我将 REST 与 Jersey 一起使用，Jackson 用于 JSON 处理。当客户端发送带有无效 JSON 的请求（在我的情况下，是无法识别的属性）时，Jackson 抛出异常（我的资源代码未执行，之前失败），但客户端获得状态代码 200。

我可以做些什么让客户得到不同的状态码吗？

我的 REST 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();
        }
    }

这是我从杰克逊的日志中得到的异常：

您可以“捕获”这些异常并引发“个性化”“WebApplicationException”，其 HTTP 代码状态/错误与该异常引发的不同。

以下是该类型个性化异常的示例，错误状态为 400（错误请求）：

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

public class PersonalizedExceptionBadRequest extends WebApplicationException{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    /**
     * Create a HTTP 400 (Bad Request) exception.
     */
    public PersonalizedExceptionBadRequest(){
        super(Response.status(400).build());
    }

    /**
     * Create a HTTP 400 (Bad Request) exception.
     * 
     * @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());
    }

}

然后你需要在你的 API jersey 方法中“声明”它“抛出”一个“WebApplicationException”。
