原始服务器拒绝处理请求,因为有效负载的格式不受目标资源上此方法的支持。
控制器代码
@RestController
public class UserController
{
@Autowired
public IretrieveService retrieveService;
@RequestMapping(value="/register", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public ModelAndView doRegister(@RequestBody UserBean userBean,BindingResult result)
{
ModelAndView view = new ModelAndView("index");
System.out.println("username "+userBean.getUsername());
if(!result.hasFieldErrors())
{
if(retrieveService.insert(userBean) != null)
{
System.out.println("done");
}
}
return view;
}
}
角度js代码
<script type="text/javascript">
var app = angular.module('myApp', []);
app.controller("UserController", ['$scope', '$http', function($scope, $http, httpPostService) {
var self=this;
self.userBean={username:''};
$scope.insertData = function()
{
alert($scope.userBean.username);
$http({
method: "POST",
url: "register",
data: $scope.userBean.username
}).then(function(response){
console.log(response.status);
console.log("in success");
}, function(response){
console.log(response.status);
console.log("in fail");
});
};
}]);
</script>
<form method="post" action="register" name="myForm">
<label for="username" class="control-label">First Name:</label>
<input type="text" data-ng-model="userBean.username" class="form-control" placeholder="Enter Firstname"/>
<button type="submit" data-ng-click="insertData()" class="btn btn-primary">Submit</button>
</form>
出现错误,但没有将值从angular js传递给控制器类

由于控制器需要application / json,但您正在发送原始字符串数据,因此出现415 http错误。
这是如何发布json数据的有效示例:
Javascript:
var data = { "name":"emre" }
$.ajax({
type: "POST",
url: "http://localhost:8080/yourUrl",
data: JSON.stringify(data),
contentType: "application/json",
cache: false,
timeout: 600000,
success: function (data) {
alert("success")
},
error: function (e) {
alert("ERROR : ", e);
}
});
控制器:
@CrossOrigin
@PostMapping
public ResponseEntity post(@RequestBody UserBean request) {
return ResponseEntity.status(HttpStatus.CREATED).body(request); // your response
}
UserBean类:
@Data // comes from lombok for getter setter purpose
class UserBean {
private String name;
}
您可以根据需要调整控制器和javascript。

在我看来,您发送到控制器的数据是String而不是UserBean对象。您的有效载荷为$scope.userBean.username
,但您的控制器希望使用@RequestBody UserBean userBean
。
将控制器更改为
public ModelAndView doRegister(@RequestBody String userName, BindingResult result)
可能会解决问题。
