【转载】Spring Boot干货系列:(十一)数据存储篇-Spring Boot整合Mybatis通用Mapper插件

  zyw090111

前言

上次介绍了Spring Boot中Mybatis的简单整合,本篇深入来结合通用Mapper、Mybatis Geneator以及分页PageHelper来打造适合企业开发的模板框架。

正文

项目框架还是跟上一篇一样使用Spring Boot的ace后端模板,不过最近在使用vue,所以前端引用了vue进来改写,代码变得更加简洁。

项目配置:

Spring Boot: 1.5.9.RELEASE
Maven: 3.5
Java: 1.8
Thymeleaf: 3.0.7.RELEASE
Vue.js: v2.5.11

数据源依赖

这里我们还是使用阿里巴巴的druid来当数据库连接池,发现这个有对应的监控界面,我们可以开启。
druid官方文档:https://github.com/alibaba/druid/wiki/常见问题

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
</dependency>

<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid</artifactId>
	<version>1.0.19</version>
</dependency>

对应的application.properties配置:

## 数据库访问配置
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/spring?useUnicode=true&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = root

# 下面为连接池的补充设置,应用到上面所有数据源中
# 初始化大小,最小,最大
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
# 配置获取连接等待超时的时间
spring.datasource.maxWait=60000
# 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis=60000
# 配置一个连接在池中最小生存的时间,单位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
# 打开PSCache,并且指定每个连接上PSCache的大小
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
spring.datasource.filters=stat,wall,log4j
# 合并多个DruidDataSource的监控数据
#spring.datasource.useGlobalDataSourceStat=true

对应的bean配置:

上面引入了mybatis相关的一些依赖以及generator的配置,这里generator配置文件指向
src/main/resources/mybatis-generator.xml文件,具体一会贴出。

对应的application.properties配置:

#指定bean所在包
mybatis.type-aliases-package=com.dudu.domain
#指定映射文件
mybatis.mapperLocations=classpath:mapper/*.xml

#mapper
#mappers 多个接口时逗号隔开
mapper.mappers=com.dudu.util.MyMapper
mapper.not-empty=false
mapper.identity=MYSQL

#pagehelper
pagehelper.helperDialect=mysql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.params=count=countSql

通用Mapper配置

通用Mapper都可以极大的方便开发人员,对单表封装了许多通用方法,省掉自己写增删改查的sql。
通用Mapper插件网址:https://github.com/abel533/Mapper

package com.dudu.util;

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;

/**
 * 继承自己的MyMapper
 *
 * @author
 * @since 2017-06-26 21:53
 */
public interface MyMapper<T> extends Mapper<T>, MySqlMapper<T> {
    //FIXME 特别注意,该接口不能被扫描到,否则会出错
}

这里实现一个自己的接口,继承通用的mapper,关键点就是这个接口不能被扫描到,不能跟dao这个存放mapper文件放在一起。

最后在启动类中通过MapperScan注解指定扫描的mapper路径:

package com.dudu;
@SpringBootApplication
//启注解事务管理
@EnableTransactionManagement  // 启注解事务管理,等同于xml配置方式的 <tx:annotation-driven />
@MapperScan(basePackages = "com.dudu.dao", markerInterface = MyMapper.class)
public class Application {
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}

MyBatis Generator配置

这里配置一下上面提到的mybatis-generator.xml文件,该配置文件用来自动生成表对应的Model,Mapper以及xml,该文件位于src/main/resources下面

                        password="${spring.datasource.password}">
        </jdbcConnection>

        <!-- 客户端代码,生成易于使用的针对Model对象和XML配置文件 的代码
                type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象
                type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口
        -->
       <javaClientGenerator type="XMLMAPPER" targetPackage="com.dudu.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
       </javaClientGenerator>

        <!--生成对应表及类名

        -->
        <table tableName="LEARN_RESOURCE" domainObjectName="LearnResource" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
        </table>
    </context>
</generatorConfiguration>

其中,我们通过``引入了配置文件,这样下面指定数据源的时候不用写死。

其中tk.mybatis.mapper.generator.MapperPlugin很重要,用来指定通用Mapper对应的文件,这样我们生成的mapper都会继承这个通用Mapper

<plugin type="tk.mybatis.mapper.generator.MapperPlugin">
	<property name="mappers" value="com.dudu.util.MyMapper" />
  <!--caseSensitive默认false,当数据库表名区分大小写时,可以将该属性设置为true-->
  <property name="caseSensitive" value="true"/>
</plugin>

这样就可以通过mybatis-generator插件生成对应的文件啦
bcd3d627ba574fa699b9580b869e3ae8-5811881c88221ba256bbc8f.png

如果不是IDEA开发环境也可以直接通过命令:mvn mybatis-generator:generate

自动生成的文件如下图所示

Controller层

到此为止,基本的配置结束了,我们开始实现业务的逻辑,Controller层代码如下

/** 教程页面
 * Created by tengj on 2017/12/19
 */
@Controller
@RequestMapping("/learn")
public class LearnController  extends AbstractController{
    @Autowired
    private LearnService learnService;
    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @RequestMapping("")
    public String learn(Model model){
        model.addAttribute("ctx", getContextPath()+"/");
        return "learn-resource";
    }

    /**
     * 查询教程列表
     * @param page
     * @return
     */
    @RequestMapping(value = "/queryLeanList",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject queryLearnList(Page<LeanQueryLeanListReq> page){
        List<LearnResource> learnList=learnService.queryLearnResouceList(page);
        PageInfo<LearnResource> pageInfo =new PageInfo<LearnResource>(learnList);
        return AjaxObject.ok().put("page", pageInfo);
    }
    /**
     * 新添教程
     * @param learn
     */
    @RequestMapping(value = "/add",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject addLearn(@RequestBody LearnResource learn){
        learnService.save(learn);
        return AjaxObject.ok();
    }

    /**
     * 修改教程
     * @param learn
     */
    @RequestMapping(value = "/update",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject updateLearn(@RequestBody LearnResource learn){
        learnService.updateNotNull(learn);
        return AjaxObject.ok();
    }

    /**
     * 删除教程
     * @param ids
     */
    @RequestMapping(value="/delete",method = RequestMethod.POST)
    @ResponseBody
    public AjaxObject deleteLearn(@RequestBody Long[] ids){
        learnService.deleteBatch(ids);
        return AjaxObject.ok();
    }
}

通用Service

正常情况下具体业务是每个模块的service里面定义许多方法,然后mapper中实现。

但是博主查看插件文档后发现一个通用Mapper在Spring4中的最佳用法。那就是通用的Service。
具体可以查看这里了解:https://gitee.com/free/Mapper2/blob/master/wiki/mapper/4.Spring4.md

定义通用service接口

/**
 * 通用接口
 */
@Service
public interface IService<T> {

 T selectByKey(Object key);

 int save(T entity);

 int delete(Object key);

 int updateAll(T entity);

 int updateNotNull(T entity);

 List selectByExample(Object example);

 //TODO 其他...
}

具体实现通用接口类

/**
 * 通用Service
 * @param <T>
 */
public abstract class BaseService<T> implements IService<T> {

    @Autowired
    protected Mapper<T> mapper;
    public Mapper<T> getMapper() {
        return mapper;
    }

    @Override
    public T selectByKey(Object key) {
        //说明:根据主键字段进行查询,方法参数必须包含完整的主键属性,查询条件使用等号
        return mapper.selectByPrimaryKey(key);
    }

    @Override
    public int save(T entity) {
        //说明:保存一个实体,null的属性也会保存,不会使用数据库默认值
        return mapper.insert(entity);
    }

    @Override
    public int delete(Object key) {
        //说明:根据主键字段进行删除,方法参数必须包含完整的主键属性
        return mapper.deleteByPrimaryKey(key);
    }

    @Override
    public int updateAll(T entity) {
        //说明:根据主键更新实体全部字段,null值会被更新
        return mapper.updateByPrimaryKey(entity);
    }

    @Override
    public int updateNotNull(T entity) {
        //根据主键更新属性不为null的值
        return mapper.updateByPrimaryKeySelective(entity);
    }

    @Override
    public List<T> selectByExample(Object example) {
        //说明:根据Example条件进行查询
        //重点:这个查询支持通过Example类指定查询列,通过selectProperties方法指定查询列
        return mapper.selectByExample(example);
    }
}

到此基本的增删改查通用service就写好了,具体业务的service就直接继承这个接口即可,也可以添加额外的方法,例如:

public interface LearnService  extends IService<LearnResource>{
    public List<LearnResource> queryLearnResouceList(Page<LeanQueryLeanListReq> page);
    public void deleteBatch(Long[] ids);
}

具体实现service

/**
 * Created by tengj on 2017/4/7.
 */
@Service
public class LearnServiceImpl extends BaseService<LearnResource>  implements LearnService {

    @Autowired
    private LearnResourceMapper  learnResourceMapper;

    @Override
    public void deleteBatch(Long[] ids) {
        Arrays.stream(ids).forEach(id->learnResourceMapper.deleteByPrimaryKey(id));
    }

    @Override
    public List<LearnResource> queryLearnResouceList(Page<LeanQueryLeanListReq> page) {
        PageHelper.startPage(page.getPage(), page.getRows());
        return learnResourceMapper.queryLearnResouceList(page.getCondition());
    }
}

可以看到,具体LearnServiceImpl这边就实现了2个方法,其他的都使用了通用service的,在开发上剩下了许多功夫。

Mapper相关

在自动生成的mapper文件中实现sevice自定义的方法:

public interface LearnResourceMapper extends MyMapper<LearnResource> {
    List<LearnResource> queryLearnResouceList(Map<String,Object> map);
}

LearnResourceMapper.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dudu.dao.LearnResourceMapper">
  <resultMap id="BaseResultMap" type="com.dudu.domain.LearnResource">
    <!--
      WARNING - @mbg.generated
    -->
    <id column="id" jdbcType="BIGINT" property="id" />
    <result column="author" jdbcType="VARCHAR" property="author" />
    <result column="title" jdbcType="VARCHAR" property="title" />
    <result column="url" jdbcType="VARCHAR" property="url" />
  </resultMap>
    <select id="queryLearnResouceList" resultType="com.dudu.domain.LearnResource">
      SELECT * from learn_resource where 1=1
      <if test="author != null and author!= ''">
        and author like CONCAT('%',#{author},'%')
      </if>
      <if test="title != null and title!= ''">
        and title like CONCAT('%',#{title},'%')
      </if>
      order by id desc
    </select>
</mapper>

IDEA可以安装这个插件,这样就可以直接从Mapper文件跳转到xml了
