使用下面提供的信息,您可以回答以下问题:
(JAXRSServerFactoryBean)RuntimeDelegate.getInstance().createEndpoint(app, JAXRSServerFactoryBean.class);
抛出非法参数异常的应用程序有什么问题?我正在尝试将使用注释(无web.xml )的JAX-RS应用程序部署到使用 Java Application Manager (这是专有系统)的系统已经移植到了一些应用程序管理器库中,但是我不确定是什么原因,因为围绕它的支持文档很少。
总体而言,我有一个Java应用程序,该应用程序使用JAX-RS批注(例如ApplicationPath,Path,Products / Consums和JsonProperty)来尝试在“应用程序服务器”上创建端点。我之所以说“应用程序服务器”,是因为我没有有关该系统的文档,因此我将其称为“应用程序服务器”。尝试启动应用程序时,出现以下异常:
java.lang.IllegalArgumentException: No container provider supports the type class org.apache.cxf.jaxrs.JAXRSServerFactoryBean
at org.glassfish.jersey.server.ContainerFactory.createContainer(ContainerFactory.java:64)
at org.glassfish.jersey.server.internal.RuntimeDelegateImpl.createEndpoint(RuntimeDelegateImpl.java:47)
at com.app.Server.startServer(Server.java:182)
我研究了java.lang.IllegalArgumentException
函数抛出的org.glassfish.jersey.server.internal.RuntimeDelegateImpl.createEndpoint
。我不确定为什么会这样做,因为在封面上看起来好像正确地注释了应用程序类并extends Application
。
我能够查看服务器的类代码,这是正在做的事情:
这是com.app.Server.startServer(Server.java:182)
代码的一部分,我无法更改此代码:
inside of startServer...
Application app = (Application) Class.forName("com.app.MyApplication").newInstance();
JAXRSServerFactoryBean jaxrsServerFactory = (JAXRSServerFactoryBean)RuntimeDelegate.getInstance().createEndpoint(app, JAXRSServerFactoryBean.class);
现在我的代码:
package com.app;
import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import com.app.services.ServiceOne;
@ApplicationPath("base/path")
public class MyApplication extends Application {
public MyApplication() {
System.out.println(Long.toString(System.nanoTime()) + " " + this.getClass().getName() + " constructor called...");
}
/* (non-Javadoc)
* @see javax.ws.rs.core.Application#getClasses()
*/
@Override
public Set<Class<?>> getClasses() {
System.out.println(Long.toString(System.nanoTime()) + " " + this.getClass().getName() + " getClasses() method called...");
Set<Class<?>> classes = new HashSet<>();
classes.add(ServiceOne.class);
return classes;
}
}
package com.app.services.ServiceOne;
import java.util.ArrayList;
import javax.ws.rs.Consumes;
import javax.ws.rs.NotFoundException;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
// pretend the model imports are here...
@Path("serviceOne")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class ServiceOne {
@PUT
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public ResponseObject performService(InputObject body) throws NotFoundException {
// do whatever to get result and send...
}

再次感谢您的帮助!

我想出了我问题的答案。
我试图将应用程序部署到的系统已经在各个目录中的系统上安装了jar
个文件。
我更新了我的应用程序以包括那些jar
文件。这是通过更新用于将应用程序部署到系统的描述符完成的。
然后,我将scope
中某些依赖项的pom.xml
设置为<scope>provided</scope>
,以便当应用程序由maven打包时,这些依赖项将不包含在最终的jar中。
下面是一个示例:
