JAX-RS 中的安全过滤器导致错误

Question

我有一个基于 JAX-RS 的应用程序，并希望根据 @RolesAllowed 注释限制对某些服务的访问。为此，我创建了一个过滤器，但配置似乎存在一些问题。 JBoss 找不到 ContainerRequestFilter （接口，它是 JAX-RS 规范的一部分，据我所知，在 RestEasy 3.x 中实现（我使用的是 3.0.4.Final）。第二个问题是 SecurityFilter ，据我所知，类被视为JPA实体，即使它没有用@Entity注释。我已经看到这个问题发布在互联网上的某个地方，但它仍然没有答案。当不包含过滤器类时，项目工作很好。

以下是消息：

Answer 1

尝试将此依赖项添加到您pom.xml 中。缺少依赖项。

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0.1</version>
</dependency>

Answer 2

我相信您没有将此类添加为提供的依赖项：

你的日志说：

Caused by: java.lang.RuntimeException: error trying to scan <jar-file>: vfs:/home/xxx/JBoss/jboss-as-7.1.0.Final/standalone/deployments/WorkersManager.war/WEB-INF/classes/
at org.hibernate.ejb.Ejb3Configuration.scanForClasses(Ejb3Configuration.java:854)
at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:596)
at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:72)

你能打开你生成的战争并寻找应该包含它的 jar 文件吗？如果它不存在，您应该提供所需的 .jar 和 .war 文件（如果您使用 maven 构建战争，您应该修改 pom.xml 以提供 .jar ）

Answer 3

好的，这有帮助：

项目属性 -> 部署程序集 -> 添加 -> 构建路径条目 -> maven 依赖项

似乎即使在 pom.xml 中添加了依赖项（之后我运行了 maven build），它们也没有包含在部署中。
