ArticleHomeDto

package com.heima.model.article.dtos;
import lombok.Data;
import java.util.Date;
@Data
public class ArticleHomeDto {
    // 最大时间
    Date maxBehotTime;
    // 最小时间
    Date minBehotTime;
    // 分页size
    Integer size;
    // 频道ID
    String tag;
}

导入heima-leadnews-article微服务

注意：需要在heima-leadnews-service的pom文件夹中添加子模块信息，如下：

    heima-leadnews-user
    heima-leadnews-article

在idea中的maven中更新一下，如果工程还是灰色的，需要在重新添加文章微服务的pom文件，操作步骤如下：

需要在nacos中添加对应的配置

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/leadnews_article?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    username: root
    password: root
# 设置Mapper接口所对应的XML文件位置，如果你在Mapper接口中有自定义方法，需要进行该配置
mybatis-plus:
  mapper-locations: classpath*:mapper/*.xml
  # 设置别名包扫描路径，通过该属性可以给包中的类注册别名
  type-aliases-package: com.heima.model.article.pojos

定义接口

package com.heima.article.controller.v1;
import com.heima.model.article.dtos.ArticleHomeDto;
import com.heima.model.common.dtos.ResponseResult;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/api/v1/article")
public class ArticleHomeController {
    @PostMapping("/load")
    public ResponseResult load(@RequestBody ArticleHomeDto dto) {
        return null;
    }
    @PostMapping("/loadmore")
    public ResponseResult loadMore(@RequestBody ArticleHomeDto dto) {
        return null;
    }
    @PostMapping("/loadnew")
    public ResponseResult loadNew(@RequestBody ArticleHomeDto dto) {
        return null;
    }
}

编写mapper文件

package com.heima.article.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.heima.model.article.dtos.ArticleHomeDto;
import com.heima.model.article.pojos.ApArticle;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import java.util.List;
@Mapper
public interface ApArticleMapper extends BaseMapper {
    public List loadArticleList(@Param("dto") ArticleHomeDto dto, @Param("type") Short type);
}

对应的映射文件

在resources中新建mapper/ApArticleMapper.xml 如下配置：



    
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
    
    
        SELECT
        aa.*
        FROM
        `ap_article` aa
        LEFT JOIN ap_article_config aac ON aa.id = aac.article_id
        
            and aac.is_delete != 1
            and aac.is_down != 1
            
            
                and aa.publish_time  #{dto.minBehotTime}
            
            
                and aa.publish_time ]]> #{dto.maxBehotTime}
            
            
                and aa.channel_id = #{dto.tag}
            
        
        order by aa.publish_time desc
        limit #{dto.size}

编写业务层代码

package com.heima.article.service;
import com.baomidou.mybatisplus.extension.service.IService;
import com.heima.model.article.dtos.ArticleHomeDto;
import com.heima.model.article.pojos.ApArticle;
import com.heima.model.common.dtos.ResponseResult;
import java.io.IOException;
public interface ApArticleService extends IService {
    /**
     * 根据参数加载文章列表
     * @param loadtype 1为加载更多  2为加载最新
     * @param dto
     * @return
     */
    ResponseResult load(Short loadtype, ArticleHomeDto dto);
}

实现类：

package com.heima.article.service.impl;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.heima.article.mapper.ApArticleMapper;
import com.heima.article.service.ApArticleService;
import com.heima.common.constants.ArticleConstants;
import com.heima.model.article.dtos.ArticleHomeDto;
import com.heima.model.article.pojos.ApArticle;
import com.heima.model.common.dtos.ResponseResult;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.Date;
import java.util.List;
@Service
@Transactional
@Slf4j
public class ApArticleServiceImpl  extends ServiceImpl implements ApArticleService {
    // 单页最大加载的数字
    private final static short MAX_PAGE_SIZE = 50;
    @Autowired
    private ApArticleMapper apArticleMapper;
    /**
     * 根据参数加载文章列表
     * @param loadtype 1为加载更多  2为加载最新
     * @param dto
     * @return
     */
    @Override
    public ResponseResult load(Short loadtype, ArticleHomeDto dto) {
        //1.校验参数
        Integer size = dto.getSize();
        if(size == null || size == 0){
            size = 10;
        }
        size = Math.min(size,MAX_PAGE_SIZE);
        dto.setSize(size);
        //类型参数检验
        if(!loadtype.equals(ArticleConstants.LOADTYPE_LOAD_MORE)&&!loadtype.equals(ArticleConstants.LOADTYPE_LOAD_NEW)){
            loadtype = ArticleConstants.LOADTYPE_LOAD_MORE;
        }
        //文章频道校验
        if(StringUtils.isEmpty(dto.getTag())){
            dto.setTag(ArticleConstants.DEFAULT_TAG);
        }
        //时间校验
        if(dto.getMaxBehotTime() == null) dto.setMaxBehotTime(new Date());
        if(dto.getMinBehotTime() == null) dto.setMinBehotTime(new Date());
        //2.查询数据
        List apArticles = apArticleMapper.loadArticleList(dto, loadtype);
        //3.结果封装
        ResponseResult responseResult = ResponseResult.okResult(apArticles);
        return responseResult;
    }
    
}

定义常量类

package com.heima.common.constants;
public class ArticleConstants {
    public static final Short LOADTYPE_LOAD_MORE = 1;
    public static final Short LOADTYPE_LOAD_NEW = 2;
    public static final String DEFAULT_TAG = "__all__";
}

编写控制器代码

package com.heima.article.controller.v1;
import com.heima.article.service.ApArticleService;
import com.heima.common.constants.ArticleConstants;
import com.heima.model.article.dtos.ArticleHomeDto;
import com.heima.model.common.dtos.ResponseResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/api/v1/article")
public class ArticleHomeController {
    @Autowired
    private ApArticleService apArticleService;
    @PostMapping("/load")
    public ResponseResult load(@RequestBody ArticleHomeDto dto) {
        return apArticleService.load(ArticleConstants.LOADTYPE_LOAD_MORE,dto);
    }
    @PostMapping("/loadmore")
    public ResponseResult loadMore(@RequestBody ArticleHomeDto dto) {
        return apArticleService.load(ArticleConstants.LOADTYPE_LOAD_MORE,dto);
    }
    @PostMapping("/loadnew")
    public ResponseResult loadNew(@RequestBody ArticleHomeDto dto) {
        return apArticleService.load(ArticleConstants.LOADTYPE_LOAD_NEW,dto);
    }
}

实现思路

Freemarker

创建一个freemarker-demo 的测试工程专门用于freemarker的功能测试与模板的测试。

pom.xml如下


    
        heima-leadnews-test
        com.heima
        1.0-SNAPSHOT
    
    4.0.0
    freemarker-demo
    
        8
        8
    
    
        
            org.springframework.boot
            spring-boot-starter-web
        
        
            org.springframework.boot
            spring-boot-starter-freemarker
        
        
            org.springframework.boot
            spring-boot-starter-test
        
        
        
            org.projectlombok
            lombok
        
        
        
            org.apache.commons
            commons-io
            1.3.2

在freemarker的测试工程下创建模型类型用于测试

package com.heima.freemarker.entity;
import lombok.Data;
import java.util.Date;
@Data
public class Student {
    private String name;//姓名
    private int age;//年龄
    private Date birthday;//生日
    private Float money;//钱包
}

在resources下创建templates，此目录为freemarker的默认模板存放目录。

在templates下创建模板文件 01-basic.ftl ，模板中的插值表达式最终会被freemarker替换成具体的数据。



    
    Hello World!


普通文本 String 展示：


Hello ${name} 
对象Student中的数据展示：

姓名：${stu.name}

年龄：${stu.age}

创建Controller类，向Map中添加name，最后返回模板文件。

package com.xuecheng.test.freemarker.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.client.RestTemplate;
import java.util.Map;
@Controller
public class HelloController {
    @GetMapping("/basic")
    public String test(Model model) {
        //1.纯文本形式的参数
        model.addAttribute("name", "freemarker");
        //2.实体类相关的参数
        
        Student student = new Student();
        student.setName("小明");
        student.setAge(18);
        model.addAttribute("stu", student);
        return "01-basic";
    }
}

01-basic.ftl，使用插值表达式填充数据



    
    Hello World!


普通文本 String 展示：


Hello ${name} 
对象Student中的数据展示：

姓名：${stu.name}

年龄：${stu.age}

创建启动类

package com.heima.freemarker;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class FreemarkerDemotApplication {
    public static void main(String[] args) {
        SpringApplication.run(FreemarkerDemotApplication.class,args);
    }
}

minIO

我们提供的镜像中已经有minio的环境

我们可以使用docker进行环境部署和启动

docker run -p 9000:9000 -p 9001:9001 --name minio -d --restart=always \ 
  -e "MINIO_ROOT_USER=minio" \
  -e "MINIO_ROOT_PASSWORD=minio123" \
  -v /home/data:/data \
  -v /home/config:/root/.minio \
  minio/minio server /data --console-address ":9001"

导入pom依赖

创建minio-demo,对应pom如下


    
        heima-leadnews-test
        com.heima
        1.0-SNAPSHOT
    
    4.0.0
    minio-demo
    
        8
        8
    
    
        
            io.minio
            minio
            7.1.0
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
            org.springframework.boot
            spring-boot-starter-test

引导类：

package com.heima.minio;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class MinIOApplication {
    public static void main(String[] args) {
        SpringApplication.run(MinIOApplication.class,args);
    }
}

创建测试类，上传html文件

package com.heima.minio.test;
import io.minio.MinioClient;
import io.minio.PutObjectArgs;
import java.io.FileInputStream;
public class MinIOTest {
    public static void main(String[] args) {
        FileInputStream fileInputStream = null;
        try {
            fileInputStream =  new FileInputStream("D:\\list.html");;
            //1.创建minio链接客户端
            MinioClient minioClient = MinioClient.builder().credentials("minio", "minio123").endpoint("http://192.168.200.130:9000").build();
            //2.上传
            PutObjectArgs putObjectArgs = PutObjectArgs.builder()
                    .object("list.html")//文件名
                    .contentType("text/html")//文件类型
                    .bucket("leadnews")//桶名词  与minio创建的名词一致
                    .stream(fileInputStream, fileInputStream.available(), -1) //文件流
                    .build();
            minioClient.putObject(putObjectArgs);
            System.out.println("http://192.168.200.130:9000/leadnews/ak47.jpg");
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}

创建模块heima-file-starter

导入依赖

    
        org.springframework.boot
        spring-boot-autoconfigure
    
    
        io.minio
        minio
        7.1.0
    
    
        org.springframework.boot
        spring-boot-starter
    
    
        org.springframework.boot
        spring-boot-configuration-processor
        true
    
    
        org.springframework.boot
        spring-boot-starter-actuator

配置类

package com.heima.file.config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import java.io.Serializable;
@Data
@ConfigurationProperties(prefix = "minio")  // 文件上传 配置前缀file.oss
public class MinIOConfigProperties implements Serializable {
    private String accessKey;
    private String secretKey;
    private String bucket;
    private String endpoint;
    private String readPath;
}

MinIOConfig

package com.heima.file.config;

import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Data
@Configuration
@EnableConfigurationProperties({MinIOConfigProperties.class})
//当引入FileStorageService接口时
@ConditionalOnClass(FileStorageService.class)
public class MinIOConfig {
   @Autowired
   private MinIOConfigProperties minIOConfigProperties;
    @Bean
    public MinioClient buildMinioClient(){
        return MinioClient
                .builder()
                .credentials(minIOConfigProperties.getAccessKey(), minIOConfigProperties.getSecretKey())
                .endpoint(minIOConfigProperties.getEndpoint())
                .build();
    }
}

封装操作minIO类

        }
    }
    /**

    @Override
    public byte[] downLoadFile(String pathUrl)  {
        String key = pathUrl.replace(minIOConfigProperties.getEndpoint()+"/","");
        int index = key.indexOf(separator);

        }
        return byteArrayOutputStream.toByteArray();

}

对外加入自动配置

在resources中新建META-INF/spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.heima.file.service.impl.MinIOFileStorageService

其他微服务使用

第一，导入heima-file-starter的依赖

第二，在微服务中添加minio所需要的配置

minio:
  accessKey: minio
  secretKey: minio123
  bucket: leadnews
  endpoint: http://192.168.200.130:9000
  readPath: http://192.168.200.130:9000

第三，在对应使用的业务类中注入FileStorageService，样例如下：

package com.heima.minio.test;
import com.heima.file.service.FileStorageService;
import com.heima.minio.MinioApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
@SpringBootTest(classes = MinioApplication.class)
@RunWith(SpringRunner.class)
public class MinioTest {
    @Autowired
    private FileStorageService fileStorageService;
    @Test
    public void testUpdateImgFile() {
        try {
            FileInputStream fileInputStream = new FileInputStream("E:\\tmp\\ak47.jpg");
            String filePath = fileStorageService.uploadImgFile("", "ak47.jpg", fileInputStream);
            System.out.println(filePath);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

在文章微服务中导入依赖

    
        org.springframework.boot
        spring-boot-starter-freemarker
    
    
        com.heima
        heima-file-starter
        1.0-SNAPSHOT

新建ApArticleContentMapper

package com.heima.article.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.heima.model.article.pojos.ApArticleContent;
import org.apache.ibatis.annotations.Mapper;
@Mapper
public interface ApArticleContentMapper extends BaseMapper {
}

6.在artile微服务中新增测试类（后期新增文章的时候创建详情静态页，目前暂时手动生成）

package com.heima.article.test;
import com.alibaba.fastjson.JSONArray;
import com.baomidou.mybatisplus.core.toolkit.Wrappers;
import com.heima.article.ArticleApplication;
import com.heima.article.mapper.ApArticleContentMapper;
import com.heima.article.mapper.ApArticleMapper;
import com.heima.file.service.FileStorageService;
import com.heima.model.article.pojos.ApArticle;
import com.heima.model.article.pojos.ApArticleContent;
import freemarker.template.Configuration;
import freemarker.template.Template;
import org.apache.commons.lang3.StringUtils;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;
@SpringBootTest(classes = ArticleApplication.class)
@RunWith(SpringRunner.class)
public class ArticleFreemarkerTest {
    @Autowired
    private Configuration configuration;
    @Autowired
    private FileStorageService fileStorageService;
    @Autowired
    private ApArticleMapper apArticleMapper;
    @Autowired
    private ApArticleContentMapper apArticleContentMapper;
    @Test
    public void createStaticUrlTest() throws Exception {
        //1.获取文章内容
        ApArticleContent apArticleContent = apArticleContentMapper.selectOne(Wrappers.lambdaQuery().eq(ApArticleContent::getArticleId, 1390536764510310401L));
        if(apArticleContent != null && StringUtils.isNotBlank(apArticleContent.getContent())){
            //2.文章内容通过freemarker生成html文件
            StringWriter out = new StringWriter();
            Template template = configuration.getTemplate("article.ftl");
            Map params = new HashMap();
            params.put("content", JSONArray.parseArray(apArticleContent.getContent()));
            template.process(params, out);
            InputStream is = new ByteArrayInputStream(out.toString().getBytes());
            //3.把html文件上传到minio中
            String path = fileStorageService.uploadHtmlFile("", apArticleContent.getArticleId() + ".html", is);
            //4.修改ap_article表，保存static_url字段
            ApArticle article = new ApArticle();
            article.setId(apArticleContent.getArticleId());
            article.setStaticUrl(path);
            apArticleMapper.updateById(article);
        }
    }
}
