我有两个JVM。
JettyJVM运行http请求,并有一个接口CarFacade,该接口使用RmiProxy FactoryBean支持到CoreJVM 中运行的CarFacadeImpl
<bean class="org.springframework.remoting.rmi.RmiProxyFactoryBeanFactory">
<property name="serviceInterface" value="org.foo.CarFacade"/>
<property name="serviceUrl" value="rmi://#{HOST}:1099/CarFacade"/>
</bean>
CoreJVM在spring容器中运行核心业务逻辑,并具有CarFacadeImpl
<bean id="carFacade" class="org.foo.impl.CarFacadeImpl"></bean>
<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
<property name="service" ref="carFacade"></property>
<property name="serviceInterface" value="org.foo.CarFacade"></property>
<property name="serviceName" value="CarFacade"></property>
<property name="replaceExistingBinding" value="true"></property>
<property name="registryPort" value="1099"></property>
</bean>
这个设置目前适用于flex/blazds,我的服务也很好地公开了。
有什么办法我也可以通过泽西岛揭露这件事吗?
我尝试了Impl上的注释(首选),但组件扫描没有找到注释(很明显,因为接口没有注释)所以我尝试在接口上添加注释,但jersey说它无法实例化接口。
// CarFacadeImpl.java - when I had the annotations on the class in the CoreJVM
@Path("car")
public class CarFacadeImpl implements CarFacade {
@GET
public String getName() {
return "CarFacade";
}
}
// CarFacade.java - When I had the annotations on the interface in JettyJVM
@Path("car")
public class CarFacade {
@GET
String getName();
}
我真的不想写一个额外的层只是通过休息暴露
我试过这里的例子http://www.webappsolution.com/wordpress/2012/03/23/one-java-service-pojo-for-amfxmljson-with-spring-blazeds-jersey-jax-rs/并且它们在没有RMI调用的情况下工作。
我找到了答案,至少泽西岛2.16。它确实需要在接口上添加注释,但这比创建一个全新的层要好得多
覆盖默认路径扫描注册并使用类似的东西注册:
// Jersey ResourceConfig
final ResourceConfig rc = new ResourceConfig();
// Get my Spring context
final ApplicationContext context = new ClassPathXmlApplicationContext("clientContext.xml");
// Use Springs class path scanner to find @Path annotated classes
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false) {
@Override
protected boolean isCandidateComponent(AnnotatedBeanDefinition beanDefinition) {
return beanDefinition.getMetadata().isIndependent();
}
};
scanner.addIncludeFilter(new AnnotationTypeFilter(Path.class));
// For each class found in package (and sub packages)
for (BeanDefinition bd : scanner.findCandidateComponents("example")) {
try {
// Get the class
Class clazz = HttpServer.class.getClassLoader().loadClass(bd.getBeanClassName());
// Get the proxy
Object bean = context.getBean(clazz);
if (bean != null) {
// Register the proxy with the interface
rc.register(bean, clazz);
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
