我正在使用REST和Jersey，以及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，无法识别的属性）时，Jackson正在抛出异常（我的资源代码未执行，之前失败），但客户端获取状态代码200。
我可以做一些事情，以便客户端获得不同的状态代码吗？
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();
}
}
以下是杰克逊日志中的例外情况：

您可以“捕获”这些异常并抛出“个性化”“WebApplicationException”，其HTTP代码状态/错误与该异常引发的错误不同。
以下是该类型的个性化异常的示例，其中包含400错误状态（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API jersey方法中“声明”它“抛出”“WebApplicationException”。
