Spring与MX4J集成实现JMX管理 （转载）

MX4J是一个开源JMX管理框架，支持JSR3 (JMX) 和JSR160 (JMX RemoteAPI)。通过Spring将MX4J集成到我们的应用系统中，可以通过HTTP协议适配，能够基于Web的方式来实现对应用系统的监控和管理。这里，使用的版本分别为：Spring 2.5

MX4J 3.0.2

MX4J对应的几个JAR文件，加入到CLASSPATH：

mx4j.jarmx4j-impl.jarmx4j-jmx.jarmx4j-remote.jarmx4j-rimpl.jarmx4j-rjmx.jarmx4j-tools.jar

首先，给出Spring的完整配置，如下所示：

view plain
  1. <?xml?version="1.0"?encoding="UTF-8"?>??<beans?xmlns="http://www.springframework.org/schema/beans"??
  2. ????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"?xmlns:p="http://www.springframework.org/schema/p"??????xsi:schemaLocation="http://www.springframework.org/schema/beans?http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">??
  3. ??????<bean?id="exporter"?class="org.springframework.jmx.export.MBeanExporter"??
  4. ????????depends-on="mbeanServer">??????????<property?name="beans">??
  5. ????????????<map>??????????????????<entry?key="CONFIG.SHIRDRN.ORG:name=config"?value-ref="config"?/>??
  6. ????????????????<entry?key="MX4J.SOURCEFORGE.COM:name=httpAdaptor"?value-ref="httpAdaptor"?/>??????????????????<!--?
  7. ????????????????<entry?key="jdmk.sun.com:name=adaptorServer"?value-ref="adaptorServer"?/>?????????????????-->??
  8. ????????????</map>??????????</property>??
  9. ????????<property?name="server"?ref="mbeanServer"?/>??????????<property?name="assembler">??
  10. ????????????<ref?bean="assembler"?/>??????????</property>??
  11. ????</bean>??????<bean?id="assembler"??
  12. ????????class="org.springframework.jmx.export.assembler.InterfaceBasedMBeanInfoAssembler">??????????<property?name="managedInterfaces">??
  13. ????????????<list>??????????????????<value>org.shirdrn.jmx.mx4j.SelectedMethodsInterface</value>??
  14. ????????????</list>??????????</property>??
  15. ????</bean>??????<bean?id="mbeanServer"?class="org.springframework.jmx.support.MBeanServerFactoryBean"?/>??
  16. ????<bean?id="httpAdaptor"?class="mx4j.tools.adaptor.http.HttpAdaptor">??????????<property?name="processor">??
  17. ????????????<ref?bean="xsltProcessor"?/>??????????</property>??
  18. ????????<property?name="host">??????????????<value>172.20.9.23</value>??
  19. ????????</property>??????????<property?name="port"?value="9988"?/>??
  20. ????</bean>??????<bean?id="xsltProcessor"?class="mx4j.tools.adaptor.http.XSLTProcessor"?/>??
  21. ????<bean?id="config"?class="org.shirdrn.jmx.mx4j.MyConfiguration"?/>????????
  22. ????<!--??????<bean?id="adaptorServer"?class="com.sun.jdmk.comm.HtmlAdaptorServer">??
  23. ????????<property?name="port">??????????????<value>9999</value>??
  24. ????????</property>??????</bean>??
  25. ????-->????
  26. </beans>???

上面配置中，比较核心的是MX4J的HTTP适配器类：mx4j.tools.adaptor.http.HttpAdaptor，它有一个processor属性，使用MX4J已经实现的mx4j.tools.adaptor.http.XSLTProcessor来对其注入。XSLTProcessor实现了MX4J定义的XML转换成为浏览器可以解析的格式的文档，就Web网页。

通过MX4J的源码可以看到，在mx4j-3.0.2/src/tools/mx4j/tools/adaptor/http/xsl目录下面，可以看到MX4J定义的一些XSLT模板，例如serverbydomain.xsl为Web控制台首页模板：

Spring配置中通过实例化一个HttpAdaptor，注册到MBeanServer中，实现基于HTTP协议远程访问管理和监控。org.shirdrn.jmx.mx4j.MyConfiguration我们定义的一个MBean，也注册到MBean Server中，实现JMX的管理与监控，代码如下所示：

view plain
  1. package?org.shirdrn.jmx.mx4j;????
  2. public?class?MyConfiguration?{??????private?long?id?=?System.currentTimeMillis();??
  3. ????private?String?name;??????public?MyConfiguration()?{??
  4. ????????super();??????}??
  5. ????public?MyConfiguration(long?id,?String?name)?{??????????super();??
  6. ????????this.id?=?id;??????????this.name?=?name;??
  7. ????}??????public?long?getId()?{??
  8. ????????return?id;??????}??
  9. ????public?void?setId(long?id)?{??????????this.id?=?id;??
  10. ????}??????public?String?getName()?{??
  11. ????????return?name;??????}??
  12. ????public?void?setName(String?name)?{??????????//?通过JMX管理调用时，更新id的值??
  13. ????????this.id?=?System.currentTimeMillis();??????????this.name?=?name;??
  14. ????}??????public?String?show()?{??
  15. ????????StringBuffer?sb?=?new?StringBuffer().append("id=").append(id).append(??????????????????",?name=").append(name);??
  16. ????????System.out.println("show()="?+?sb.toString());??????????return?sb.toString();??
  17. ????}??}??

但是，Spring配置中的org.springframework.jmx.export.assembler.InterfaceBasedMBeanInfoAssembler对MBean暴露的操作进行了限制，主要是通过我们定义的接口org.shirdrn.jmx.mx4j.SelectedMethodsInterface来指定需要将MBean的哪些内容暴露给JMX管理，接口如下所示：

view plain
  1. package?org.shirdrn.jmx.mx4j;????
  2. public?interface?SelectedMethodsInterface?{????????public?long?getId();????
  3. ????public?void?setName(String?name);??????public?String?getName();??
  4. ????public?void?show();????}??

最后，我们可以初始化Spring的IOC容器，启动MX4J的HttpAdaptor服务，实现通过Web控制台的JMX管理，代码如下所示：

view plain
  1. package?org.shirdrn.jmx.mx4j;????
  2. import?java.io.IOException;??import?javax.management.MalformedObjectNameException;??
  3. import?mx4j.tools.adaptor.http.HttpAdaptor;??import?org.springframework.context.ApplicationContext;??
  4. import?org.springframework.context.support.ClassPathXmlApplicationContext;????
  5. public?class?JMXTest?{??????public?static?void?main(String[]?args)?throws?IOException,??
  6. ????????????MalformedObjectNameException,?Exception?{??????????ApplicationContext?ctx?=?new?ClassPathXmlApplicationContext(??
  7. ????????????????new?String[]?{?"org/shirdrn/jmx/mx4j/applicationContext.xml"?});??????????HttpAdaptor?httpAdaptor?=?(HttpAdaptor)?ctx.getBean("httpAdaptor");??
  8. ????????httpAdaptor.start();??????}??
  9. }??

启动成功后，可以通过浏览http://192.168.1.102:9988，可以看到我们注册的MBean，并对其进行管理和监控。
