优化这段代码@Autowired private UserService userService; @RequestMapping("/addUser") public ReturnCodeUtil addUser(@RequestBody User user) { ReturnCodeUtil returnCodeUtil = new ReturnCodeUtil(); if(null == user.getUserFlag()){ returnCodeUtil.setResult(false); return returnCodeUtil; } int res = this.userService.addUser(user); if (res>0) { returnCodeUtil.setResult(true); } else { returnCodeUtil.setResult(false); } return returnCodeUtil; } @RequestMapping("/register") public ReturnCodeUtil register(@RequestBody User user) { ReturnCodeUtil returnCodeUtil = new ReturnCodeUtil(); if(user == null) { returnCodeUtil.setResult(false); return returnCodeUtil; } int res = this.userService.addUser(user); if(res>0){ returnCodeUtil.setResult(true); }else returnCodeUtil.setResult(false); return returnCodeUtil; }

这段代码中存在重复的逻辑，可以将其优化为以下代码：

@Autowired
private UserService userService;

@RequestMapping("/addUser")
public ReturnCodeUtil addUser(@RequestBody User user) {
ReturnCodeUtil returnCodeUtil = new ReturnCodeUtil();
if (user.getUserFlag() == null || user == null) {
returnCodeUtil.setResult(false);
return returnCodeUtil;
}
int res = this.userService.addUser(user);
returnCodeUtil.setResult(res > 0);
return returnCodeUtil;
}

@RequestMapping("/register")
public ReturnCodeUtil register(@RequestBody User user) {
return addUser(user);
}

这样做的优点是减少了重复代码，提高了代码的可读性和维护性。同时，将两个方法合并为一个可以减少代码量，简化代码逻辑。
