sprinboot整合mybatis, 有2种方式, 第一种完全使用注解的方式, 还有一种就是使用xml文件的方式
项目使用gradle + idea, 数据源使用druid, 多使用groovy编写
环境配置
1, 依赖
dependencies { compile("org.springframework.boot:spring-boot-devtools") compile("org.springframework.boot:spring-boot-starter") compile("org.springframework.boot:spring-boot-starter-web") compile("org.springframework.boot:spring-boot-starter-log4j2") compile("com.fasterxml.jackson.dataformat:jackson-dataformat-yaml") compile("org.codehaus.groovy:groovy-all:2.4.11") compile ‘mysql:mysql-connector-java‘ compile ‘com.alibaba:druid-spring-boot-starter:1.1.2‘ compile ‘org.mybatis.spring.boot:mybatis-spring-boot-starter:1.1.1‘ compile ‘javax.inject:javax.inject:1‘ testCompile group: ‘junit‘, name: ‘junit‘, version: ‘4.12‘ testCompile("org.springframework.boot:spring-boot-starter-test") }
2, user-schame.sql
在springboot的配置文件中, 增加 schema, 可以在程序启动时创建数据表, 插入数据等操作
SET FOREIGN_KEY_CHECKS=0; DROP TABLE IF EXISTS `users`; CREATE TABLE `users` ( `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT ‘主键id‘, `userName` varchar(32) DEFAULT NULL COMMENT ‘用户名‘, `passWord` varchar(32) DEFAULT NULL COMMENT ‘密码‘, `user_sex` varchar(32) DEFAULT NULL, `nick_name` varchar(32) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=28 DEFAULT CHARSET=utf8;
3, application.yml
spring: profiles: active: dev http: encoding: charset: UTF-8 force: true enabled: true server: tomcat: uri-encoding: UTF-8 --- # 开发环境 spring: profiles: dev datasource: url: jdbc:mysql://localhost:3306/springboot username: root password: root type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver # schema: classpath:user-schema.sql # data: classpath:user-data.sql server: context-path: /security port: 8010 --- # 测试环境配置 spring: profiles: qa --- # 生产环境配置 spring: profiles: prod
4, Main.groovy
package com.wenbronk.security import org.mybatis.spring.annotation.MapperScan import org.springframework.boot.SpringApplication import org.springframework.boot.autoconfigure.SpringBootApplication /** * Created by wenbronk on 2017/8/14. */ @SpringBootApplication @MapperScan("com.wenbronk.security.mapper") class SecurityApplication { static void main(String[] args) { SpringApplication.run(SecurityApplication.class) } }
5, UserEntity.groovy
package com.wenbronk.security.entity /** * Created by wenbronk on 2017/8/14. */ class UserEntity { def id def userName def passWord def userSex def nickName @Override public String toString() { return "UserEntity{" + "id=" + id + ", userName=" + userName + ", passWord=" + passWord + ", userSex=" + userSex + ", nickName=" + nickName + ‘}‘; } }
6, UserSexEnum
package com.wenbronk.security.enums; /** * Created by wenbronk on 2017/8/14. */ public enum UserSexEnum { MAN, WOMAN }
完全使用注解的方式:
1, usermapper
package com.wenbronk.security.mapper; import com.wenbronk.security.entity.UserEntity; import com.wenbronk.security.enums.UserSexEnum; import org.apache.ibatis.annotations.*; import java.util.List; /** * Created by wenbronk on 2017/8/14. */ public interface UserMapper { @Select("SELECT * FROM users") @Results({ @Result(property = "userSex", column = "user_sex", javaType = UserSexEnum.class), @Result(property = "nickName", column = "nick_name") }) List<UserEntity> findAll(); @Select("SELECT * FROM users WHERE id = #{id}") @Results({ @Result(property = "userSex", column = "user_sex", javaType = UserSexEnum.class), @Result(property = "nickName", column = "nick_name") }) UserEntity findOne(Long id); @Insert("INSERT INTO users(userName,passWord,user_sex) VALUES(#{userName}, #{passWord}, #{userSex})") void insert(UserEntity user); @Update("UPDATE users SET userName=#{userName},nick_name=#{nickName} WHERE id =#{id}") void update(UserEntity user); @Delete("DELETE FROM users WHERE id =#{id}") void delete(Long id); }
2, 测试类
package com.wenbronk.security.test import com.wenbronk.security.entity.UserEntity import com.wenbronk.security.enums.UserSexEnum import com.wenbronk.security.mapper.UserMapper import org.junit.Test import org.junit.runner.RunWith import org.springframework.boot.test.context.SpringBootTest import org.springframework.test.context.junit4.SpringJUnit4ClassRunner import javax.inject.Inject /** * Created by wenbronk on 2017/8/14. */ @RunWith(SpringJUnit4ClassRunner.class) @SpringBootTest class MybatisTest { @Inject UserMapper userMapper; @Test void insert() { userMapper.insert(new UserEntity(userName: ‘vini‘, passWord: ‘123‘, userSex: UserSexEnum.WOMAN, nickName: ‘H‘)) userMapper.insert(new UserEntity(userName: ‘bronk‘, passWord: ‘123‘, userSex: UserSexEnum.MAN, nickName: ‘H‘)) } @Test void query() { def find = userMapper.findAll() println find } }

使用xml的方式
1, application.yml中添加
mybatis.config-locations=classpath:mybatis/mybatis-config.xml mybatis.mapper-locations=classpath:mybatis/mapper/*.xml
2, mybatis-config.xml
<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>
3, user的映射文件
<mapper namespace="com.neo.mapper.UserMapper" > <resultMap id="BaseResultMap" type="com.neo.entity.UserEntity" > <id column="id" property="id" jdbcType="BIGINT" /> <result column="userName" property="userName" jdbcType="VARCHAR" /> <result column="passWord" property="passWord" jdbcType="VARCHAR" /> <result column="user_sex" property="userSex" javaType="com.neo.enums.UserSexEnum"/> <result column="nick_name" property="nickName" jdbcType="VARCHAR" /> </resultMap> <sql id="Base_Column_List" > id, userName, passWord, user_sex, nick_name </sql> <select id="getAll" resultMap="BaseResultMap" > SELECT <include refid="Base_Column_List" /> FROM users </select> <select id="getOne" parameterType="java.lang.Long" resultMap="BaseResultMap" > SELECT <include refid="Base_Column_List" /> FROM users WHERE id = #{id} </select> <insert id="insert" parameterType="com.neo.entity.UserEntity" > INSERT INTO users (userName,passWord,user_sex) VALUES (#{userName}, #{passWord}, #{userSex}) </insert> <update id="update" parameterType="com.neo.entity.UserEntity" > UPDATE users SET <if test="userName != null">userName = #{userName},</if> <if test="passWord != null">passWord = #{passWord},</if> nick_name = #{nickName} WHERE id = #{id} </update> <delete id="delete" parameterType="java.lang.Long" > DELETE FROM users WHERE id =#{id} </delete> </mapper>
4, dao代码
public interface UserMapper { List<UserEntity> getAll(); UserEntity getOne(Long id); void insert(UserEntity user); void update(UserEntity user); void delete(Long id); }
