mybatis- 获取自增ID

1、环境：

mybatis : 3.2.3

spring-mybatis:  1.2.1

mysql:5.5.29

实体：

public class sys_user {    private int userid;    private String username;       public int getUserid() {        return userid;    }    public void setUserid(Integer userid) {        this.userid = userid;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username == null ? null : username.trim();    }    

 

insert 节点配置：

  <insert id="insert" parameterType="com.mamaguwen.entity.sys_user"   useGeneratedKeys="true" keyProperty="userid">      <!--    <selectKey keyProperty="userid" resultType="int" order="BEFORE">         SELECT LAST_INSERT_ID()  as  userid     </selectKey> -->    insert into sys_user ( UserName)    values (#{username})  </insert>

keyProperty:对应为实体字段值

调用代码：

sys_UserDao.insert(model);
System.out.println("getUserid:"+ model.getUserid());
