Question

我试图实现RESTEasy + Spring，但@Autowire无法正常工作。我找到了一些参考资料，我需要使用org.jboss.resteasy.plugins.spring.SpringContextLoaderListener并禁用resteasy自动扫描。我已经尝试了，但现在我的网络服务无法识别。我做错了什么？这是我的web.xml

<?xml version="1.0" encoding="UTF-8" ?>

这是我的网络服务

@Service
@Path("/json")
public class ApplicationSupportSvc {

    @Autowired
    private MobileSurveyApkRepo mobileSurveyApkRepo;

    @GET
    @Path("/latest")
    @Produces(MediaType.APPLICATION_JSON)
    @Transactional
    public ApkResponse getLatestApk() {

        return mobileSurveyApkRepo.getLatestApk();
    }

}

这是我的applicationContext.xml

我使用RESTEasy 3.0.6和Spring 4.0.3，使用JBOSS EAP 6.2

Answer 1

RESTEasy和Spring 4存在一个错误：https://issues.jboss.org/browse/RESTEASY-1012

根据问题的说明创建您自己的ContextLoaderListener实施。

Answer 2

此错误已在Resteasy 3.0.9中修复。最终： https://github.com/resteasy/Resteasy/blob/master/jaxrs/resteasy-spring/src/main/java/org/jboss/resteasy/plugins/spring/SpringContextLoaderListener.java

现在您可以使用以下内容：

    public Response ehlo(@PathParam("msg") String msg) {
        return Response.ok().entity(msg).build();
    }

}

Answer 3

您还需要一个弹簧配置文件。 RESTEasy期望在WEB-INF目录中有一个applicationContext.xml文件。

此文件应包含类似于：

的内容

<context:component-scan base-package="
    my.package"/>

Answer 4

有两种方法可以解决这个问题 1）使用some.package是声明MobileSurveyApkRepo的地方。要么 2）获取Webapplciationcontext并获取bean 为什么你要自动装配它，为什么你这样做呢？ MobileSurveyApkRepo mobileSurveyApkRepo = ctx.getBean（＆＃34; mobileSurveyApkRepoImpl＆＃34;，MobileSurveyApkRepo.class）;

Answer 5

由于您必须进行重新安装的自动扫描，您可能需要列出您的其他服务：

<context-param>
    <param-name>resteasy.resources</param-name>
    <param-value>com.mypackage.MyRESTService</param-value>
</context-param>

RESTEasy的SpringContextLoaderListener没有扫描@Path
