这是一种可以实现的方法，与Jersey实现其日志记录过滤器的方式非常相似。您可以阅读该实体并将其粘贴回请求，因此您不小心在过滤器中不使用它。

request.setEntityInputStream(new ByteArrayInputStream(requestEntity));
}
return request;
} catch (IOException ex) {
throw new ContainerException(ex);
}
}

b.append(new String(entity)).append("\n");
System.out.println("#### Intercepted Entity ####");
System.out.println(b.toString());
}
}
