dao里面
int updateUsers(UserInput userInput);
service里面
Dto updateUsers(UserInput userInput);
serviceImpl里面
@Override
public Dto updateUsers(UserInput userInput) {
Dto dto =new Dto();
userMapper.updateUsers(userInput);
return dto;
}
controller里面
@RequestMapping(value = "/updateUsers",method =RequestMethod.POST)
@ResponseBody
public Dto updateUsers(@RequestBody UserInput userInput) {
return userService.updateUsers(userInput);
}
用的是postman测的
结果传参示例:
{
"userList":[
{
"uid":13,
"uname":"测试13",
"age":"24",
"sex":"2",
"phone":"12435435"
},
{
"uid":14,
"uname":"测试14",
"age":"24",
"sex":"2",
"phone":"12435435"
}
]
}
返回结果示例:
{
"code": 0,
"msg": "success"
}
