mybatis 1 - 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());
