Java 弹簧座控制器POST请求不存在'；行不通

我有一个休息控制器：

@RestController
@RequestMapping("/query")
public class QueryController {

    @Autowired
    private QueryService queryService;

    @RequestMapping(value = "/select", method = RequestMethod.POST)
    public @ResponseBody QueryResultDTO executeQuery(@RequestBody QueryDTO queryDTO) {
        try {
            QueryResultDTO queryResultDTO = queryService.executeQuery("select * from employees");
            queryResultDTO.setSuccessful(true);
            return queryResultDTO;
        } catch (SQLException e) {
            QueryResultDTO queryResultDTO = new QueryResultDTO();
            queryResultDTO.setSuccessful(false);
            queryResultDTO.setErrorMessage(e.getMessage());
            return queryResultDTO;
        }
    }
}

app.controller("AppCtrl",function($scope,$http) {
    var app = this;

    $scope.execute= function () {
        $http({
            url: '../query/select',
            method: "POST",
            data: { 'message' : $scope.queryText }
        })
            .then(function(response) {
                    $scope.queryResult = response.data;
                    console.log($scope.queryResult);
                    console.log($scope.queryText)
                },
                function(response) {
                    console.log(response);
                });
    }

});

app.controller("AppCtrl",function($scope,$http) {
    var app = this;

    $scope.execute= function () {
        $http({
            url: '../query/select',
            method: "GET",
            data: { 'message' : $scope.queryText }
        })
            .then(function(response) {
                    $scope.queryResult = response.data;
                    console.log($scope.queryResult);
                    console.log($scope.queryText)
                },
                function(response) {
                    console.log(response);
                });
    }

});

我尝试从AngularJS控制器发送POST请求：

@RestController
@RequestMapping("/query")
public class QueryController {

    @Autowired
    private QueryService queryService;

    @RequestMapping(value = "/select", method = RequestMethod.POST)
    public @ResponseBody QueryResultDTO executeQuery(@RequestBody QueryDTO queryDTO) {
        try {
            QueryResultDTO queryResultDTO = queryService.executeQuery("select * from employees");
            queryResultDTO.setSuccessful(true);
            return queryResultDTO;
        } catch (SQLException e) {
            QueryResultDTO queryResultDTO = new QueryResultDTO();
            queryResultDTO.setSuccessful(false);
            queryResultDTO.setErrorMessage(e.getMessage());
            return queryResultDTO;
        }
    }
}

app.controller("AppCtrl",function($scope,$http) {
    var app = this;

    $scope.execute= function () {
        $http({
            url: '../query/select',
            method: "POST",
            data: { 'message' : $scope.queryText }
        })
            .then(function(response) {
                    $scope.queryResult = response.data;
                    console.log($scope.queryResult);
                    console.log($scope.queryText)
                },
                function(response) {
                    console.log(response);
                });
    }

});

app.controller("AppCtrl",function($scope,$http) {
    var app = this;

    $scope.execute= function () {
        $http({
            url: '../query/select',
            method: "GET",
            data: { 'message' : $scope.queryText }
        })
            .then(function(response) {
                    $scope.queryResult = response.data;
                    console.log($scope.queryResult);
                    console.log($scope.queryText)
                },
                function(response) {
                    console.log(response);
                });
    }

});

但它不起作用。Spring控制器中的My

executeQuery

函数甚至没有被调用

但当我改变RequestMethod以使其正确工作时

@RestController
@RequestMapping("/query")
public class QueryController {

    @Autowired
    private QueryService queryService;

    @RequestMapping(value = "/select", method = RequestMethod.GET)
    public @ResponseBody QueryResultDTO executeQuery() {
        try {
            QueryResultDTO queryResultDTO = queryService.executeQuery("INSERT INTO employee VALUES (7,'dupa')");
            queryResultDTO.setSuccessful(true);
            return queryResultDTO;
        } catch (SQLException e) {
            QueryResultDTO queryResultDTO = new QueryResultDTO();
            queryResultDTO.setSuccessful(false);
            queryResultDTO.setErrorMessage(e.getMessage());
            return queryResultDTO;
        }
    }
}

在角度控制器中：

@RestController
@RequestMapping("/query")
public class QueryController {

    @Autowired
    private QueryService queryService;

    @RequestMapping(value = "/select", method = RequestMethod.POST)
    public @ResponseBody QueryResultDTO executeQuery(@RequestBody QueryDTO queryDTO) {
        try {
            QueryResultDTO queryResultDTO = queryService.executeQuery("select * from employees");
            queryResultDTO.setSuccessful(true);
            return queryResultDTO;
        } catch (SQLException e) {
            QueryResultDTO queryResultDTO = new QueryResultDTO();
            queryResultDTO.setSuccessful(false);
            queryResultDTO.setErrorMessage(e.getMessage());
            return queryResultDTO;
        }
    }
}

app.controller("AppCtrl",function($scope,$http) {
    var app = this;

    $scope.execute= function () {
        $http({
            url: '../query/select',
            method: "POST",
            data: { 'message' : $scope.queryText }
        })
            .then(function(response) {
                    $scope.queryResult = response.data;
                    console.log($scope.queryResult);
                    console.log($scope.queryText)
                },
                function(response) {
                    console.log(response);
                });
    }

});

app.controller("AppCtrl",function($scope,$http) {
    var app = this;

    $scope.execute= function () {
        $http({
            url: '../query/select',
            method: "GET",
            data: { 'message' : $scope.queryText }
        })
            .then(function(response) {
                    $scope.queryResult = response.data;
                    console.log($scope.queryResult);
                    console.log($scope.queryText)
                },
                function(response) {
                    console.log(response);
                });
    }

});

我的主要问题是，我想向我的Spring控制器发送一些数据，然后向我的Angular控制器发送

JSON

。Whith

GET

methodresponse工作得很好，但是当我使用

POST

时，甚至没有调用controller方法

编辑：

我的

QueryDTO

类很简单：

public class QueryDTO {

    private String message;

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}

以及一些具有

DEBUG

级别的日志：

2016-06-06 09:28:23.697 DEBUG 7504 --- [nio-8090-exec-2] o.s.web.servlet.DispatcherServlet        : Null ModelAndView returned to DispatcherServlet with name 'dispatcherServlet': assuming HandlerAdapter completed request handling
2016-06-06 09:28:23.698 DEBUG 7504 --- [nio-8090-exec-2] o.s.web.servlet.DispatcherServlet        : Successfully completed request

尝试在方法中添加

consumes=MediaType.APPLICATION\u JSON\u值

@Transactional
@RequestMapping(value = "/userlogincheck", method = RequestMethod.POST,   consumes=MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody void userLoginCheck(@RequestBody UserImpl user, HttpServletRequest request, HttpServletResponse response) throws JSONException, IOException {
JSONObject json = new JSONObject();
    try {
        String email=user.getEmail();
        Long userId=user.getId();
        User loginData = accountService.userLoginCheck(email,userId);
        if(loginData==null)
        {
            json.put("status", "FAILURE");
            json.put("message", "user does not exist");
            json.put("nextPage", "signIn");
        }
        else
        {
            json.put("status", "SUCCESS");
            json.put("nextPage", updateState);
        }
    }
    catch(Exception e) {
        logger.info(e.getMessage());
    }
    response.setContentType("application/json;charset=UTF-8");
    logger.info("response======" + json.toString());
    PrintWriter out = response.getWriter();
    out.write(json.toString());
}

我也遇到了同样的问题，通过向我的请求中添加CSRF令牌可以解决这个问题（只有在使用Web安全性时，这才是一个问题）

此链接描述了以下步骤：

1） 将令牌添加到您的头中，使用thymeleaf，您可以执行以下操作（我认为您也可以从cookie中获取令牌）：

QueryTo需要哪些属性？请张贴其代码。你试过做出明确的回应吗？定义。最后，您还可以尝试更改公司添加。您的QueryTo看起来怎么样？如果Spring message converter正在将JSON转换为QueryTo，您是否检查了日志。我已经用QueryTo代码和一些日志更新了我的帖子。您能否将org.springframework.web设置为在日志配置中调试并粘贴跟踪？QueryTo需要哪些属性？请张贴其代码。你试过做出明确的回应吗？定义。最后，您还可以尝试更改公司添加。您的QueryTo看起来怎么样？如果Spring message converter正在将JSON转换为QueryTo，您是否检查了日志。我已经用QueryTo代码和一些日志更新了我的帖子。您能否将org.springframework.web设置为在日志配置中调试并粘贴跟踪？
