需求：使用MyBatis往MySQL数据库中插入一条记录后，需要返回该条记录的自增主键。 方法：在mapper中指定keyProperty属性，示例如下： insert id=insertAndGetId useGeneratedKeys=true keyProperty=userId parameterType=com.chenzhou.mybatis.Userinsert in

需求：使用MyBatis往MySQL数据库中插入一条记录后，需要返回该条记录的自增主键值。

 

方法：在mapper中指定keyProperty属性，示例如下：

<insert id="insertAndGetId" usegeneratedkeys="true" keyproperty="userId" parametertype="com.chenzhou.mybatis.User">
	insert into user(userName,password,comment)
	values(#{userName},#{password},#{comment})
</insert>
Copy after login

如上所示，我们在insert中指定了keyProperty="userId"，其中userId代表插入的User对象的主键属性。
