200尽管存在Jackson错误，但从REST返回的状态代码

我将REST用于Jersey，Jackson用于JSON处理。当客户端发送一个带有无效JSON的请求（在我的例子中，是无法识别的属性）时，Jackson抛出了一个异常（我的资源代码没有执行，它以前失败过），但是客户端得到了状态代码200

我可以做些什么让客户端获得不同的状态码吗

我的休息方法：

    @PUT
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Response myMethod(MyClass message)
    {
        try
        {
            //my logic here
            return Response.ok(result).build();
        }
        catch (Exception e)
        {
            return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity(e.getMessage()).build();
        }
    }

以下是我从Jackson的日志中得到的例外情况：

您可以“捕获”这些异常并抛出一个“个性化的”WebApplicationException，其HTTP代码状态/错误与该异常抛出的不同

以下是该类型个性化异常的示例，具有400错误状态（错误请求）：

---

然后，您需要在API jersey方法中“声明”它“抛出”一个“WebApplicationException”。

我试过这么做。我添加了您的类并声明我的方法抛出“PersonalizedExceptionBadRequest”，但它不起作用。什么不起作用？它给了你什么错误？尝试声明API方法抛出一个“WebApplicationException”，看看它是否返回相同的问题。它不起作用，这意味着我仍然得到200个响应。这是我的方法签名：公共响应myMethod（MyMessage message）抛出PersonalizedExceptionBadRequest但在抛出此新异常之前，您是否“捕获”了您在原始问题中报告的异常（UnrecognizedPropertyException）？我无法捕获它，因为它不是从我的代码中抛出的。如果我试图为“UnrecognizedPropertyException”添加catch子句，我将得到编译错误-“错误：exception UnrecognizedPropertyException从未在相应的try语句体中抛出”将资源方法的代码添加到问题中。听起来你正在接受JSON异常，导致“成功”响应。我可以添加我的代码，但我认为这不会有什么帮助。我没有“吞咽”JSON异常。我的代码甚至没有被执行，它在进入我的代码之前失败了。奇怪的是，你肯定应该得到一个HTTP 500状态，而不是一个200状态。不是对原始问题的回答，但为了消除异常，您可以在POJO中添加一个。

import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.Response;

public class PersonalizedExceptionBadRequest extends WebApplicationException{

    /**

    private static final long serialVersionUID = 1L;

    /**

    public PersonalizedExceptionBadRequest(){
        super(Response.status(400).build());
    }

    /**

     * 
     * @param message
     *            the String that is the entity of the 400 response.
     */
    public PersonalizedExceptionBadRequest(String message){
        super(Response.status(400).entity(message).type("text/plain")
                .build());
    }
