球衣项目中的类别施放异常？(Class cast exception in jersey project?)

球衣项目中的类别施放异常？(Class cast exception in jersey project?)

我有一个球衣休息项目和一个新手问题。 从服务器端：

throw new WebApplicationException(Response.status(Status.NOT_FOUND) .entity("no access token found").build());

从客户端

else if (Status.fromStatusCode(response.getStatus()) == Status.NOT_FOUND || Status.fromStatusCode(response.getStatus()) == Status.GONE) { final VerifyTokenResponse verifyTokenResponse = new VerifyTokenResponse(); verifyTokenResponse.setError((String) response.getEntity()); return verifyTokenResponse; }

问题是

java.lang.ClassCastException: org.glassfish.jersey.client.HttpUrlConnector$1 cannot be cast to java.lang.String

为什么我不能在客户端获取错误字符串？ 这是正确的（String）response.getEntity（）吗？

I have a jersey rest project and one newbie question. From server side:

throw new WebApplicationException(Response.status(Status.NOT_FOUND) .entity("no access token found").build());

From client side

else if (Status.fromStatusCode(response.getStatus()) == Status.NOT_FOUND || Status.fromStatusCode(response.getStatus()) == Status.GONE) { final VerifyTokenResponse verifyTokenResponse = new VerifyTokenResponse(); verifyTokenResponse.setError((String) response.getEntity()); return verifyTokenResponse; }

Problem is

java.lang.ClassCastException: org.glassfish.jersey.client.HttpUrlConnector$1 cannot be cast to java.lang.String

Why I can't get error string on client side ? Is this correct (String) response.getEntity() for that ?

最满意答案

你需要使用response.readEntity(String.class)而不是(String) response.getEntity()

You need to use response.readEntity(String.class) instead of (String) response.getEntity()
