406不可接受：Spring MVC + JSON

我知道这个问题已经被问过很多次了，虽然我尝试了已经说过的话，但我仍然有这个问题。我正试图生成一个简单的JSON响应工作。现在我得到406不可接受的错误。 Tomcat说：“这个请求标识的资源只能根据请求”接受“头文件生成不可接受的特征的响应。” 在tomcat/lib我有jackson罐子。我使用Spring 1.1.0和Tomcat 7 我addedd在pom.xml的依赖关系：406不可接受：Spring MVC + JSON

CompaniesRestController.java

@RequestMapping(value = "/Companies", method = RequestMethod.GET) 
    @ResponseBody 
    public List<Companies> listCompaniess() { 
     return new java.util.ArrayList<Companies>(companiesService.loadCompaniess()); 
    }

我在applicationContext.xml添加此代码段如在所描述的：reference：

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 
    <property name="messageConverters"> 
     <util:list id="beanList"> 
     <ref bean="stringHttpMessageConverter"/> 
     <ref bean="marshallingHttpMessageConverter"/> 
     </util:list> 
    </property 
</bean> 

<bean id="stringHttpMessageConverter" 
     class="org.springframework.http.converter.StringHttpMessageConverter"/> 

<bean id="marshallingHttpMessageConverter" 
     class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter"> 
    <property name="marshaller" ref="castorMarshaller" /> 
    <property name="unmarshaller" ref="castorMarshaller" /> 
</bean>

但徒劳无益，没有任何工作。

我会很感谢您的建议。

PS：我用脚手架来生成我的CRUD应用程序。

其实，当我编辑 CompaniesRestController.java

@RequestMapping(value = "/Companies", method = RequestMethod.GET) 
    @ResponseBody 
    public String<Companies> listCompaniess() { 
     return new java.util.ArrayList<Companies>(companiesService.loadCompaniess()).toString(); 
    }

或

@RequestMapping(value = "/Companies", method = RequestMethod.GET,produces="application/json") 

    public @ResponseBody Object[] listCompaniess() { 
     return new java.util.ArrayList<Companies>(companiesService.loadCompaniess()).toArray(); 

    }

我不再有406error，我得到包含数组记录我在我的数据库中，但作为一个数组，不是一个JSON ...

我试过如果使用JSONObject，但仍然有相同的问题，我用脚手架来创建我的spring mvc应用程序，然后将其转换为Maven项目以添加jackson库和依赖项，但是当我cenvert它，所有的项目坍塌并引发以下错误：

可生产媒体类型映射的请求也可以由Spring的配置@RequestMapping。

例如：@RequestMapping(value = "/list", method = RequestMethod.GET, produces = "application/json")

我已经尝试过这个注释，但仍然有同样的问题。 – user1567118

根据您更新的问题，您现在不会收到该错误，并且您获取的数据不是JSON格式。您可以通过两种方式使用JSON格式：1 - 返回您自己的Model对象而不是Object [] 2-如果您不想创建新的Model对象，请使用JSONObject。 –

我拥有的项目真的很庞大，所以我无法承担编辑每个班级的费用，以便返回我自己的模型对象 *即使JSONObject不起作用，仍然有406错误 – user1567118
