在我的宠物项目中，我有一个简单的jersey（v 2.13）资源执行一些crud操作，输入由hibernate-validator（v 5.0.1.Final）验证。 问题是虽然junit测试按预期工作，但当我部署webapp时，所有ExceptionMapper实现都会被忽略。
这里有一些细节：
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public JsonResult<User> addUser(@Valid Userbean user) {
//do stuff...
}
验证由hibernate-validator完成。
Userbean注释为：
@NotNull
private String password;
我已经创建了一个ExceptionMapper实现：
@Provider
public class ValidationExceptionMapper implements ExceptionMapper<ValidationException> {
@Override
public Response toResponse(ValidationException e) {
return Response.status(422).build();
}
}
暂不考虑验证时，正确的状态代码应为400，我的问题是，在我的junit-test中，一切都很顺利......
Userbean entity = new Userbean();
entity.setUsername(username);
Response response = target.path("users").request(MediaType.APPLICATION_JSON).post(Entity.json(entity));
int status = response.getStatus();
assertEquals(422 status);
...当我在tomcat上运行它时，我无法重现相同的行为（我已尝试过tomcat7 / tomcat 8以及glassfish 4.1）
我总是得到一个400状态代码而不是422，并且正在跳过ValidationExceptionMapper。

在测试服务器上进行的相同调用按预期工作：
curl -v -X POST -H "Content-Type: application/json" --data "{\"username\":\"MrFoo\"}" http://localhost:8080/users/
* About to connect() to localhost port 8080 (#0)

< Content-Type: application/json
< Date: Sun, 28 Dec 2014 15:05:35 GMT

我用于junit的服务器的代码是：
@Before
public void setUpClient() throws Exception {
ResourceConfig rc = new UserResourceConfig();
rc.property("contextConfig", appContext);
server = GrizzlyHttpServerFactory.createHttpServer(BASE_URI, rc);
server.start();
....
提前感谢您的帮助。
