mybatis MySQL返回插入的主键ID,oracle不行

<insertid=“doSomething"parameterType="map"useGeneratedKeys="true"keyProperty=“yourId">

...

</insert>

或

<insert id=“doSomething" parameterType=“com.xx.yy.zz.YourClass" useGeneratedKeys="true" keyProperty=“yourId">

...

</insert>

直接用插入对象的ID来接收就行

User user = new User();
user.setUserName("chenzhou");
user.setPassword("xxxx");
user.setComment("测试插入数据返回主键功能");  

System.out.println("插入前主键为："+user.getUserId());
userDao.insertAndGetId(user);//插入操作
System.out.println("插入后主键为："+user.getUserId());
