返回状态 >=400 时如何获取 http 响应内容。那是我的代码示例：

    try {
        ChatService client = ProxyFactory.create(ChatService.class, apiUrl);
        client.putMessage(dto);
    } catch (ClientResponseFailure ex) {
        System.out.println(ex.getResponse().getEntity().toString());
    }

这抛出：

Exception in thread "main" org.jboss.resteasy.spi.ReaderException: java.io.IOException: Stream closed
    at org.jboss.resteasy.core.messagebody.ReaderUtility.doRead(ReaderUtility.java:123)

我想了解更多详细信息，而不仅仅是状态码 400。

那是您要发送的例外吗？

不幸的是，RestEASY 客户端框架本身不支持异常编组，而是将其适配到 HTTP 框架中。但是仍然应该在服务器上抛出异常。我从来没有做过，你可以使用 ExceptionMappers 来检查异常。

调试时，我注意到我需要的细节在“streamFactory”对象中作为 XML 的字节流。我在有关ClientResponse的 RestEasy 文档中找到了这个帮助主题。它说

getEntity(java.lang.Class<T2> type)

其中 getEntity 可以将输出编组到所需的类。就我而言，我有一个自定义类，用于从名为 ServiceError 的服务返回的错误。所以，这就是我传递给 getEntity 的类：

try {
    serviceResult = proxy.addCustomer(customerName, customerProfile);
} catch (ClientResponseFailure ex) {
    ClientResponse<String> cResp = ex.getResponse();
    ServiceError myEntity = cResp.getEntity(ServiceError.class);
    System.out.println("myEntity errorText=" + myEntity.getErrorMessage().getErrorText());
    System.out.println("myEntity errorCode=" + myEntity.getErrorMessage().getErrorCode());
}
