java - ClassNotFoundException : org. glassfish.jersey.internal.RuntimeDelegateImpl 在具有嵌入式 cxf 依赖项的 OSGi 包中找不到

Question

这与 jax-rs-2-0-change-default-implementation 有关
我有一个由 cxf 2.7.8 和 openejb 组成的 OSGi 包。 cxf 依赖项作为嵌入式依赖项添加。
当我尝试部署 web 应用程序时，出现以下异常。
当我在启动服务器时将系统属性设置为 -Djavax.ws.rs.ext.RuntimeDelegate=org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl这可以解决。
但是在上面的链接中它说当我有 META-INF/services/javax.ws.rs.ext.RuntimeDelegate文件内容为org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl这可以解决。
在我的 OSGi 包中，该文件存在于 cxf-rt-frontend-jaxrs-2.7.8.jar 中。但是这个 jar 嵌入在 OSGi 包中似乎没有正确选择。我尝试将相同的文件添加到 OSGi 包 META-INF/services但它也没有用。
有人能告诉我有没有办法在不手动设置系统属性的情况下摆脱这种情况？java.lang.ExceptionInInitializerError at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:191) at com.sun.proxy.$Proxy89.<clinit>(Unknown

Answer 1

能够在这里找到答案:https://wso2.org/jira/browse/WSAS-1870

基本上你需要添加一个系统属性来设置默认委托(delegate):

javax.ws.rs.ext.RuntimeDelegate=org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl
