自动连线不'；t为RESTEasy和Spring 3工作

在RESTEasy 2.2.1.GA和Spring 3.0.5.RELEASE中使用@Autowired时遇到问题。我每次都会得到NPE

String result = customerBo.getMsg();

为我服务

如何更正代码的自动连线行为

这是我的RESTEasy服务：

@Component
@Path("/api")
public class Rest {

    @Autowired
    CustomerBo customerBo;

      @GET
      @Produces("text/plain")
      public String getXMLMessage() {
              String result = customerBo.getMsg();
              return result;
      }
}

这是我的web.xml：

我的问题解决了。 问题是，对于实现，我使用了来自不同版本库的不同来源的文章

我在官方文件中找到了我的问题的正确答案：

---

根据文档，SpringContextLoaderListener必须在ResteasyBootstrap之后声明，因为它使用由它初始化的ServletContext属性

org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap

org.jboss.resteasy.plugins.spring.SpringContextLoaderListener

---

你能发布你的web.xml吗？你不应该等太久。这是一个研究项目，所以它仍然可以包含错误。最后一个版本放在这里：我已经像你一样评论了行代码

，但这是正确的方式吗？是的，RESTEasy使用自己的

org.jboss.RESTEasy.plugins.spring.SpringContextLoaderListener

我可以知道你是如何解决这个问题的吗？实际上，我不能使用自动连线。我必须依赖于使用applicaton的上下文获取bean实例。我认为在您的情况下，您最好创建新的问题。顺致敬意，
