Spring MVC应用程序不接受JSON

我不明白为什么我不能将更新发布到我的控制器。我试图通过chrome插件提交json数据。最终我将使用angular来处理请求。我对照其他stackoverflow文章进行了检查，似乎他们建议的我都有了

对于它的价值，我有一个GET请求到同一个工作正常的控制器

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.  

我的服务器日志显示以下内容

INFO - Mapped "{[/service/products/addProduct],methods=[POST],params=[],headers=[],consumes=[application/json],produces=[],custom=[]}" onto public void com.cr.controllers.ProductsController.addProduct(com.cr.entity.Products)

邮寄地址

http://localhost:8082/service/products/addProduct

正在发布的数据

{
    "productId": 2,
    "productModel": "Product Model 2",
    "productName": "Product Name 2",

}

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);
}

web.xml

   <servlet-mapping>
        <servlet-name>cr</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <filter>
        <filter-name>httpMethodFilter</filter-name>
        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>httpMethodFilter</filter-name>
        <servlet-name>cr</servlet-name>
    </filter-mapping>

这里是放大的定义和要求

 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")
            }
        });

我需要向jsonConverter bean添加以下内容

<property name="prefixJson" value="false"/>

最后的Bean如下所示

 <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="prefixJson" value="false"/>
        <property name="supportedMediaTypes" value="application/json"/>
    </bean>

您是否可以检查您的客户端是否发送了正确的内容类型头，application/jsonSpring MVC取决于Jackson（1或2）以处理JSON输入或输出。你的类路径中有jackson库吗？发布你提交数据的客户端代码，问题似乎出在客户端我添加的客户端代码中，还有一个新的错误message@CostiCiudatu我确实有杰克逊，但我失去了一处房产。

<property name="prefixJson" value="false"/>

 <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="prefixJson" value="false"/>
        <property name="supportedMediaTypes" value="application/json"/>
    </bean>
