本文介绍了如何在Spring Boot项目中整合Mybatis，并详细说明了如何配置pom.xml以打包成WAR包。特别提示，XML配置文件需放置在resources目录下，确保能被正确扫描。

1.pom.xml

注：要打包war包的话，要加

<packaging>war</packaging>和<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>，如果要在idea中调试的话，要把<scope>provided</scope>注释，否则运行会失败

</project>

2. Mapper.java

package hello.dao;

import hello.bean.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.mybatis.spring.annotation.MapperScan;

/**
 * Created by Administrator on 2016/11/20.
 */
@Mapper()
public interface UserMapper {

    @Select("select * from user1 where u_id = #{u_id}")
    User findById(@Param("u_id")String u_id);
    User selectByCode(String u_code);
}

3. mapper.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="hello.dao.UserMapper" >
    <resultMap id="BaseResultMap" type="hello.bean.User" >
        <result column="U_ID" property="u_id" jdbcType="INTEGER" />
        <result column="U_CODE" property="u_code" jdbcType="VARCHAR" />
    </resultMap>
    <select id="selectByCode" resultMap="BaseResultMap" parameterType="java.lang.String" >
        select
        *
        from User1
        where U_CODE = #{u_code,jdbcType=VARCHAR}
    </select>
</mapper>

4. application.properties

注：idea下xml文件要放在resources下，否则扫描不到

spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=test
spring.datasource.password=123
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
server.port=1111

mybatis.mapper-locations=classpath*:mapper/*.xml
5. Application.java

package hello;

import org.mybatis.spring.annotation.MapperScan;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

/**
 * Created by Administrator on 2016/11/20.
 */
@SpringBootApplication    
public class Application extends SpringBootServletInitializer {
    private static final Logger log = LoggerFactory.getLogger(Application.class);
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
    public static void main(String []args){
        SpringApplication.run(Application.class, args);
    }

}
