Spring JMX代理接口问题
[英]Spring JMX proxy interface issue
问题描述
I'm trying out Spring + JMX bean configuration in my project. 
我正在我的项目中尝试Spring + JMX bean配置。 I'm new to JMX technology. 我是JMX技术的新手。 I need to implement the proxyinterface way in managed beans. 我需要在托管bean中实现proxyinterface方式。 When tried, I'm getting the below mentioned error. 尝试时，出现以下错误。
Can anyone guide me? 谁能指导我？ I'm trying out to deploy my war in tomcat. 我正在尝试在Tomcat中部署战争。 On the context initialization of the applicaiton on startup, I'm getting InvalidInvocationException 关于启动时应用程序的上下文初始化，我得到了InvalidInvocationException
Interface 接口
package my.pjt.test.location;
public interface AppResourceLocationMBean {
String getLocation();
void setLocation(String location);
}
Implementing class 实施班
package my.pjt.test.location;
public class AppResourceLocation implements AppResourceLocationMBean {
private volatile String location = "classpath:**/app-resource/**/";
@Override public String getLocation() {
return location;
}
@Override public void setLocation(String location) {
this.location = location;
}
}
Used in AppLoader 在AppLoader中使用
package my.pjt.test.location;
public class AppLoader {
private volatile AppResourceLocationMBean appLocationMBean;
public void init() throws Exception {
...........
String appLocation = this.appLocationMBean.getLocation();
..........
}
}

Trying with your sample; 尝试您的样品； when I added throws OperationException as I suggested, I get... 当我按照建议添加throws OperationException ，我得到...
Caused by: javax.management.InstanceNotFoundException: test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001
This comment makes no sense: 此评论没有任何意义：
<!-- Enabling below bean and disabling the above bean worked for me. But need a proxy interface solution. -->
The proxy is aa proxy for the real MBean not a replacement for it - the MBean has to exist in the server. 该代理是真实MBean的代理 ，不能代替它-MBean必须存在于服务器中。
There is no such MBean "test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001" - you can see that by opening VisualVM or JConsole. 没有这样的MBean“ test：name = appLocationConfiguration，type = SpringAppLocationConfiguration，context = pjt001”-您可以通过打开VisualVM或JConsole看到这一点。
However, even with the MBean defined, the root cause of your problem is that you are trying to access it from an init() method before the context is loaded. 但是，即使定义了MBean，问题的根本原因是，您试图在加载上下文之前从init()方法访问它。
Here is a revised version of your test context that works just fine because I removed the reference to the apploader in the MBeanExporter and moved the appLoader to below the MBeanExporter. 这是测试上下文的修订版，可以正常工作，因为我删除了MBeanExporter中对apploader的引用，并将appLoader移至MBeanExporter下方。
<bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean">
<property name="locateExistingServerIfPossible" value="true"></property>
</bean>
<bean id="appConfigLocationMBean" class="org.springframework.jmx.access.MBeanProxyFactoryBean">
<property name="objectName" value="test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001"/>
<property name="proxyInterface" value="com.my.config.app_loader.AppResourceLocationMBean"/>
</bean>
<!-- Enabling below bean and disabling the above bean worked for me. But need a proxy interface solution. -->
<bean id="actualAppConfigLocationMBean" class="com.my.config.app_loader.AppResourceLocation"/>
<bean id="mbeanExporter" class="org.springframework.jmx.export.MBeanExporter">
<property name="beans">
<map>
<!-- Used to add additional application contexts at runtime. -->
<entry key="test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001"
value-ref="actualAppConfigLocationMBean" />
</map>
</property>
</bean>
<bean id="appLoader" class="com.my.config.app_loader.AppLoader">
<property name="appLocationMBean" ref="appConfigLocationMBean" />
</bean>
However, I would recommend implementing SmartLifecycle and do the lookup in start() rather than init() , because then you can be sure that all the beans in the context have been initialized. 但是，我建议实现SmartLifecycle并在start()而不是init()进行查找，因为这样可以确保上下文中的所有bean均已初始化。
