spring与mybatis的使用
作者：互联网
1、spring与mybatis整合配置文件版
spring与mybaits整合需要一个中间包mybatis-spring，将mybatis交给spring管理，中间包pom依赖如下
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>2.0.3</version>
</dependency>
完整pom依赖如下
<dependencies>
<dependency>

<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>

mybatis config配置
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<setting name="mapUnderscoreToCamelCase" value="true"/>
<setting name="logImpl" value="STDOUT_LOGGING"/>
</settings>
<typeAliases>
<package name="com.wonders.bigdata.domain"/>
</typeAliases>
<!-- 配置映射文件：用来配置sql语句和结果集类型等 -->
<mappers>
<mapper resource="WebsitesMapper.xml"/>
</mappers>
</configuration>
之后需要对实体对应的mapper文件进行编写，有xml或者注解的方式进行定义，mapper文件如下。
package com.wonders.bigdata.mapper;
import com.wonders.bigdata.domain.Websites;
import com.wonders.bigdata.domain.WebsitesExample;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import java.util.List;
public interface WebsitesMapper {
int countByExample(WebsitesExample example);
int deleteByExample(WebsitesExample example);
int deleteByPrimaryKey(Long id);
int insert(Websites record);
int insertSelective(Websites record);
List<Websites> selectByExample(WebsitesExample example);
Websites selectByPrimaryKey(Long id);
int updateByExampleSelective(@Param("record") Websites record, @Param("example") WebsitesExample example);
int updateByExample(@Param("record") Websites record, @Param("example") WebsitesExample example);
int updateByPrimaryKeySelective(Websites record);
int updateByPrimaryKey(Websites record);
@Select("select * from bd_websites where id = #{id}")
Websites findById(Long id);
}
对应service编写
package com.wonders.bigdata.spring.service;
import com.wonders.bigdata.domain.Websites;
public interface WebsitesService {
Websites findById(Long id);
}
package com.wonders.bigdata.spring.service.impl;
import com.wonders.bigdata.domain.Websites;
import com.wonders.bigdata.mapper.WebsitesMapper;
import com.wonders.bigdata.spring.service.WebsitesService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class WebsitesServiceImpl implements WebsitesService {
@Autowired
private WebsitesMapper websitesMapper;
@Override
public Websites findById(Long id) {
return websitesMapper.findById(id);
}
}
测试
@Test
public void springContext() {
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:application-context.xml");
MessageService messageService = context.getBean(MessageService.class);
WebsitesService websitesService = context.getBean(WebsitesService.class);
System.out.println(messageService.getMessage());
System.out.println(websitesService.findById(1L));
}
