Question

我目前正在通过Sprint Boot学习AngularJS，并使用POST请求。我知道后端工作正常，但是，我试图弄清楚使用复选框和Spring Boot MVC可能是什么问题。如果我的代码不好，请原谅。

错误消息：

{
 "status" : "400",
 "cause" : null,
 "method" : "POST",
 "message" : "Required request body is missing: public void com.velatt.dartentitlements.api.SiteController.addServicesToSite(java.lang.Long,org.springframework.hateoas.Resources<com.velatt.dartentitlements.domain.DeService>) throws java.net.URISyntaxException",
 "exception" : "HttpMessageNotReadableException",
 "path" : "/sites/1/services",
 "error" : "Bad Request"
}

Answer 1

您必须像下面这样从ajax传递身体：

        $http({
            method: 'POST',
            url: "/sites/" + $scope.targetEntity.siteId + "/services",
            headers: {'Content-Type': 'application/x-www-form-urlencoded'},
            data:addRequest,
        }).then(function (response) {
            $scope.services = response.data;
        });

Answer 2

尝试这样的事情。

angularJs

// create array to hold request data
var selectedObjArray = [];

// push data to array.
 selectedObjArray.push(....);


$http({
        method: 'POST',
        url: "/sites/" + $scope.targetEntity.siteId + "/services",
        headers: {'Content-Type': 'application/json'},   // change content type to json
        data:selectedObjArray ,
    }).then(function (response) {
        $scope.services = response.data;
    });

Spring MVC

@RequestMapping(value = "/sites/{id}/services", method = RequestMethod.POST, headers = { "Content-type=application/json" })
public void addServicesToSite(@PathVariable Long id, @RequestBody List<DeService> incoming) throws URISyntaxException {
    for (Link link : incoming.getLinks()) {
        DeService deService = utilityService.getDomainObjectFromUriString(link.getHref(), DeService.class);
        service.addServiceToSite(id, deService);
    }
}
