我正在
415 Unsupported Media Type - The server refused this request because the request entity is in a format not supported by the requested resource for the requested method
请求网址为:

从弹簧控制器读取时出现错误;我检查了相同模式的其他控制器方法,它们工作正常但不是我新引入的那个。我找不到它的任何问题,你能否建议我错过什么?
我的控制器:
@RequestMapping(value = "/review/{key}", method = RequestMethod.GET, consumes = "", produces = "application/json")
public
@ResponseBody
List<Review> reviews(@PathVariable(value = "key") String key) {
System.out.println("key : " + key);
List<Review> reviewList = reviewService.getReviewsById(key);
System.out.println("reviewList : " + reviewList.size());
return reviewList;
}
Angular的My Services.js:
services.factory('PostFactory', ['$resource', function ($resource) {
alert("I am here service");
return {
postmain: $resource('/ngdemo/web/posts', {}, {
query: {method: 'GET', isArray: true },
create: {method: 'POST'}
}),
reviews: $resource('/ngdemo/web/posts/review/:key', {}, {
query: {method: 'GET', params: {key: '@key'} },
create: {method: 'POST'}
}),
postreview: $resource('/ngdemo/web/posts/getreview', {}, {
query: {method: 'GET', isArray: true },
create: {method: 'POST'}
}),
allresults: $resource('/ngdemo/web/posts/result/:tag', {}, {
query: {method: 'GET', params: {tag: '@tag'} },
create: {method: 'POST'}
})};
}]);
我的controller.js中的代码打电话:
var reviewId = place.id;
$scope.allreviews = PostFactory.reviews.query({key: reviewId})
我无法找到问题所在,所以你们可以看看并指出我错过了什么?谢谢!

为什么您的consumes
参数设置为""
?
如果:
consumes = "",
Content-Type
HTTP标头然后它应该工作。

它的工作原理是:
@Consumes("text/html")
@Consumes("text/html")
@RequestMapping(value = "/review/{key}", method = RequestMethod.GET, produces = "application/json")
public
@ResponseBody
List<Review> reviews(@PathVariable(value = "key") String key) {

查看网络选项卡,首先需要确认Angular是否在URL中发送参数,可能您的请求是发送有关请求有效负载的信息。
错误415是错误的转换信息。 @PathVariable是一个在url中获取参数的注释:
https://stackoverflow.com/ {pathVariableParam} /
使用注释@RequestBody
创建一个对象并将其插入到方法中@RequestMapping(value = "/review", method = RequestMethod.GET, consumes = "", produces = "application/json")
public
@ResponseBody List<Review> reviews(@RequestBody String key) { // Or (@RequestBody ObjectKey key)
System.out.println("key : " + key);
List<Review> reviewList = reviewService.getReviewsById(key);
System.out.println("reviewList : " + reviewList.size());
return reviewList;
}
