| <h2>JMX演示用例</h2> | ||
|
|
||
| <h4>技术说明：</h4> | ||
| <h3>技术说明：</h3> | ||
| <ul> | ||
| <li>服务端演示使用Spring annotation定义MBean</li> | ||
| <li>演示使用Spring annotation将POJO定义为MBean</li> | ||
| <li>演示使用jolokia将JMX输出为Restul JSON Monitor API</li> | ||
| </ul> | ||
|
|
||
| <h4>用户故事：</h4> | ||
| <div> | ||
| 使用JMX动态配置查看和配置Log4J日志等级。<br /> 客户端可使用JConsole或JManager, 远程进程URL为 localhost:2099 | ||
| 或完整版的service:jmx:rmi:///jndi/rmi://localhost:2099/jmxrmi | ||
| </div> | ||
| <h3>MBean介绍:</h3> | ||
| <ul> | ||
| <li>Log4j Mbean，控制Log4j的Logger Level, name为log4j:name=Log4j</li> | ||
| <li>Application Statistics Mbean, 当用户在综合演示里查看/更新用户时，计数器将会递增, name为showcase:name=ApplicationStatistics</li> | ||
| </ul> | ||
|
|
||
| <h3>使用Jconsole或其他JMX客户端:</h3> | ||
| <ul> | ||
| <li>如果JConsole与应用在同一台机器，直接选择该进程。</li> | ||
| <li>否则远程进程URL为 localhost:2099 或完整版的service:jmx:rmi:///jndi/rmi://localhost:2099/jmxrmi</li> | ||
| </ul> | ||
|
|
||
| <h3>与国际接轨的Resultful API:</h3> | ||
| <ul> | ||
| <li>获取所有统计信息: <a href="${baseUrl}/jolokia/read/showcase:name=ApplicationStatistics">${baseUrl}/jolokia/read/showcase:name=ApplicationStatistics</a></li> | ||
| <li>获取展示用户列表次数: <a href="${baseUrl}/jolokia/read/showcase:name=ApplicationStatistics/ListUserTimes">${baseUrl}/jolokia/read/showcase:name=ApplicationStatistics/ListUserTimes</a></li> | ||
| <li>获取重置清零统计信息: <a href="${baseUrl}/jolokia/exec/showcase:name=ApplicationStatistics/resetStatistics">${baseUrl}/jolokia/exec/showcase:name=ApplicationStatistics/resetStatistics</a></li> | ||
| <li>获取showcase域下所有MBean的属性: <a href="${baseUrl}/jolokia/read/showcase:name=*">${baseUrl}/jolokia/read/showcase:name=*</a></li> | ||
| <li>获取特定Logger的Level: <a href="${baseUrl}/jolokia/exec/log4j:name=Log4j/getLoggerLevel/org.springside">${baseUrl}/jolokia/exec/log4j:name=Log4j/getLoggerLevel/org.springside</a></li> | ||
