JavaMelody初使用

第一步pom文件

<!-- javamelody-core -->
<dependency>
<groupId>net.bull.javamelody</groupId>
<artifactId>javamelody-core</artifactId>
<version>1.58.0</version>
</dependency>
<!-- itext, option to add PDF export -->
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7</version>
<exclusions>
<exclusion>
<artifactId>bcmail-jdk14</artifactId>
<groupId>bouncycastle</groupId>
</exclusion>
<exclusion>
<artifactId>bcprov-jdk14</artifactId>
<groupId>bouncycastle</groupId>
</exclusion>
<exclusion>
<artifactId>bctsp-jdk14</artifactId>
<groupId>bouncycastle</groupId>
</exclusion>
</exclusions>
</dependency>

第二歩web.xml

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:net/bull/javamelody/monitoring-spring-datasource.xml
classpath*:/applicationContext.xml
</param-value>
</context-param>

<filter>
<filter-name>javamelody</filter-name>
<filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
<async-supported>true</async-supported>
</filter>
<filter-mapping>
<filter-name>javamelody</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>ASYNC</dispatcher>
</filter-mapping>
<listener>
<listener-class>net.bull.javamelody.SessionListener</listener-class>
</listener>

classpath:net/bull/javamelody/monitoring-spring-datasource.xml 这句一定要写在上面

第三歩：监控数据源

<bean id="mainDataSource" class="net.bull.javamelody.SpringDataSourceFactoryBean">
<property name="targetName" value="dataSource" />
</bean>

这里的数据源dataSource 是项目中数据源bean的id

完成以上步骤，访问

http://<host>:<port>/projectName/monitoring

就可以看到监控的页面了





这个链接默认是所有人都访问的，我们可以加一个filter 来过滤/monitoring的请求

public class JavaMelodyFilter extends net.bull.javamelody.MonitoringFilter{

@Override
public void doFilter(ServletRequest srequest, ServletResponse sresponse, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) srequest;
String uri = request.getRequestURI();
if (uri.indexOf("/monitoring") != -1) {
User user = (User)SecurityUtils.getSubject().getSession().getAttribute("user");
if(user == null || user.getIdentity()!=UserType.SYS){
return;
}
}
super.doFilter(srequest, sresponse, chain);
}

}

注意filter要继承net.bull.javamelody.MonitoringFilter
