SpringBoot整合Mybatis

spring boot中使用mybatis有不少坑，特別是不同版本之間的兼容性等。這裏使用spring boot 1.5.9.版本和mybatis-spring-boot-starter 1.3.0版本。

 下面接着定義mybatis的配置文件，在src/main/resource目錄下：

mybatis/config.xml：

<?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>
	<typeAliases>
		<typeAlias alias="Integer" type="java.lang.Integer" />
		<typeAlias alias="Long" type="java.lang.Long" />
		<typeAlias alias="HashMap" type="java.util.HashMap" />
		<typeAlias alias="LinkedHashMap" type="java.util.LinkedHashMap" />
		<typeAlias alias="ArrayList" type="java.util.ArrayList" />
		<typeAlias alias="LinkedList" type="java.util.LinkedList" />
	</typeAliases>
</configuration>

mybatis/mapper/devdata.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="rfidData.mapper.DevDataMapper" >
	<resultMap id="DevDataMap" type="rfidData.entity.DevDataEntity" >  
        <result column="devId" property="devId" jdbcType="VARCHAR" />
        <result column="assetId" property="assetId" jdbcType="VARCHAR" />
        <result column="name" property="name" jdbcType="VARCHAR" />       
        <result column="kind" property="kind" jdbcType="VARCHAR" />
    </resultMap>
    <select id="getDevDataList" parameterType="java.lang.String"  resultMap="DevDataMap" >
        SELECT 
       devId,assetId,name,kind 
	   FROM t_rfid_dev limit 100
	   
    </select>
</mapper>

application.properties:

mybatis.config-locations=classpath:mybatis/config.xml
mybatis.mapper-locations=classpath:mybatis/mapper/*.xml
mybatis.type-aliases-package=rfidData.entity

# DATABASE
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/zkMonitor?characterEncoding=utf8&useSSL=true
spring.datasource.username=root
spring.datasource.password=123456

spring.datasource.driverClassName=com.mysql.jdbc.Driver

然後定義mapper類：

public interface DevDataMapper {
    List<DevDataEntity> getDevDataList(String id);
}
在service中使用mapper類：

@Service
public class DevDataService {

	@Autowired
	DevDataMapper devDataMapper;
	
	public List<DevDataEntity> getDevDataList() {		 
		return devDataMapper.getDevDataList("a");
		
	}
}

最後，在啓動類中添加@MapperScan註解：

@MapperScan("rfidData.mapper")

成功運行！！
