用jersey2搭建restful平台时遇到的问题

由 霸气de小男生 提交于 2020-01-07 08:18:50
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前几天用jersey2搭建了一个restful平台，今天在测试的时候发现一个问题，如果一个没有权限的用户访问了限制资源，那么正确的返回结果应该为401。问题就在这里发生了，我写了一个测试用例，第一次访问的时候返回401，再次请求时就成了200，往后再怎么试都是200，除非重启应用。看看了日志发现报错了: An I/O error has occurred while writing a response message entity to the container output stream. ! java.lang.IllegalStateException: The output stream has already been closed. 看到了，当服务端往请求的客户端通道中返回数据时，发现客户端的通道已经关闭了。哦，明白了，看看了代码，发现问题的所以，如下： final Response ACCESS_DENIED = Response.status(Response.Status.UNAUTHORIZED).entity("无权限访问！").build(); 起初这段代码是做filter的类变量而使用的，也就是说定义了一个Response重复在使用，这样做是不对的，随后把改成了局部变量

Jersey, Guice using non-root request paths

由 流过昼夜 提交于 2020-01-06 14:19:13
问题 I'm using Jersey 1.11 over Guice 3.0 on Tomcat 6.0.32 in a standard configuration: configureServlets() { filter("/ws/*").through(GuiceContainer.class); } And a simple resource class: @Path("/resource") public class Resource { ... } Given that, I would suppose that accessing "/ws/resource" would work; but actually no resources are found. The problem seems to lie in the request path not being computed correctly. As a workaround I have set the parameter PROPERTY_FILTER_CONTEXT_PATH to /ws ,

parsing subnodes with Jersey

由 做~自己de王妃 提交于 2020-01-06 02:23:08
问题 We are connecting to a third party using Jersey. We then want to extract the returned xml into our class. This is actually working fine except for one node in the xml that is in a subnode. Here is the xml returned: <response> ... <langISO>en</langISO> <acquirerAmount>1000</acquirerAmount> <acquirerCurrency>GBP</acquirerCurrency> <subXml> <authCode>122958</authCode> </subXml> </response> Note that the authCode node is in a subnode (called subXml). OurResponse myriadResponse = response
