一、POJO
public class User {
private Integer userId;
private String name;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
二、数据库表
CREATE TABLE `t_user` ( `user_id` int(11) NOT NULL AUTO_INCREMENT COMMENT ‘用户ID‘, `name` varchar(18) NOT NULL COMMENT ‘用户名‘, PRIMARY KEY (`user_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT=‘用户表‘
三、Mybatis映射文件中SQL语句
<insert id="insert" parameterType="com.xxx.xxxx.pojo.User">
insert into t_user (name)
values (#{user.name})
<selectKey resultType="Integer" order="AFTER" keyProperty="user.userId">
SELECT LAST_INSERT_ID() AS userId
</selectKey>
</insert>
四、Dao层接口
void insert(@Param("user") User user);
五、Service层实现
@Override
public void insert() {
User user = new User();
user.setName("zain");
dao.insert(user);
System.out.println(user.getUserId); //发现ID已经获取了
}
