我不明白爲什麼我不能將更新發布到我的控制器。我正在嘗試通過Chrome插件提交json數據。最終,我將對請求使用角度。我檢查了其他的stackoverflow文章,似乎我有他們建議的一切。Spring MVC應用程序不接受JSON
爲什麼它的價值我有一個GET請求到工作沒有問題的同一個控制器。
HTTP Status 415 - The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.
我的服務器日誌顯示以下

控制器映射
@RequestMapping(value = "/service/products/addProduct",
consumes = "application/json",
method= RequestMethod.POST)
public @ResponseBody void addProduct(@RequestBody Products products){
productsDao.createProduct(products);
}
的web.xml
<servlet-mapping>
<servlet-name>cr</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<filter>
<filter-name>httpMethodFilter</filter-name>

_ UPDATE _ _
我開始使用放大做我的請求,因爲我想確保它不是鍍鉻加上。我現在得到了400。以下是我的服務器上顯示的錯誤。
org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Can not deserialize instance of com.cr.entity.Products out of START_ARRAY token
at [Source: [email protected]; line: 1, column: 1]; nested exception is org.codehaus.jackson.map.JsonMappingException: Can not deserialize instance of com.cr.entity.Products out of START_ARRAY token
at [Source: [email protected]; line: 1, column: 1
這裏是放大定義和請求。
amplify.request.define("addRequest", "ajax", {
url: "service/products/addProduct",
type: "POST",
dataType: 'json',
contentType: 'application/json'
});
amplify.request({
resourceId: "addRequest",
data: JSON.stringify(jsonData),
success: function() {
alert("success")
},
error: function() {
alert("fail")
}
});
數據:
var jsonData = [{
"productId": 4,
"productModel": "Product Model 2",
"productName": "Product Name 2",
"dateAdded": 1361880001000,
"productWeight": 2,

您可以檢查您的客戶端發送正確的Content-Type頭,應用/ JSON – gouki 2013-03-01 02:41:43
Spring MVC的依賴於傑克遜(或者1或者2)爲了處理JSON輸入或輸出。你的classpath中有沒有jackson庫? – 2013-03-01 06:56:10
發佈您提交數據的客戶端代碼,問題似乎在客戶端 – Kris 2013-03-01 10:34:08
