監控效果圖見本文結尾部分.

3.在web.xml中配置filter:

1. <filter>
2.         <filter-name>monitoring</filter-name>
3.         <
   filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
4.         <init-param>
5.             <param-name>log</param-name>
6.             <param-value>true</param-value>
7.         </init-param>
8.     </filter>
9.     <filter-mapping>
10.         <filter-name>
    monitoring</filter-name>
11.         <url-pattern>/*</url-pattern>
12.     </filter-mapping>
13.     <listener>
14.         <listener-class>net.bull.javamelody.SessionListener</listener-class>
15.     </listener>

至此,基本配置已完成,可以進行簡單的效能監控,下面配置是javamelody與struts2和spring3的整合配置:

1. <packagename="base"namespace="/"extends="struts-default">
2.         <result-types>
3.             <result-typename="json"class="org.apache.struts2.json.JSONResult"/>
4.         </result-types>
5.         <interceptors>
6.             <!-- javamelody -->
7.             <interceptorname="monitoring"class="net.bull.javamelody.StrutsInterceptor"/>
8.             <interceptor-stackname="myStack">
9.                 <interceptor-refname="monitoring"/>
10.                 <!-- 
11.                     struts預設的攔截器 
12.                 -->
13.                 <interceptor-refname="defaultStack"/>
14.             </interceptor-stack>
15.         </interceptors>
16.         <default-interceptor-refname="myStack"/>

1. <packagename="example"namespace="/"extends="base">
2.         <actionname="student_*"class="studentAction"method="{1}">
3.             <resultname="input">/pub_error.jsp</result>
4.         </action>
5.     </package>

1. <beanid= "facadeMonitoringAdvisor"class="net.bull.javamelody.MonitoringSpringAdvisor">
2.          <propertyname ="pointcut">
3.                  <beanclass="org.springframework.aop.support.JdkRegexpMethodPointcut">
4.                          <propertyname ="pattern"value="com.proj.*.service.*"/><!--正則表示式-->
5.                  </bean>
6.          </property>
7. </bean>

7.如果你的所有spring管理的bean都實現了介面,用步驟6中的配置一切OK,但如果有些bean沒有實現介面,使用步驟6中的配置將會出錯.
則將步驟6中的配置改為(這樣將使用cglib代理):
spring配置檔案中配置:
<bean id= "facadeMonitoringAdvisor" class="net.bull.javamelody.MonitoringSpringAdvisor" >
         <property name ="pointcut" >
                 <bean class="org.springframework.aop.support.JdkRegexpMethodPointcut" >
                         <property name ="pattern" value="com.proj.*.service.*" /><!--正則表示式-->
                 </bean>
         </property>
</bean>


方式一,web.xml中加入如下配置:
<context-param>
<param-name> contextConfigLocation</param-name>
             <param-value>
                  classpath:applicationContext*.xml<!--Spring配置檔案-->
                  classpath:net/bull/javamelody/monitoring-spring-aspectj.xml<!--和spring整合時新增-->
             </param-value>
</context-param>


方式二,在spring.xml中加入如下配置:
<import resource="classpath:net/bull/javamelody/monitoring-spring-aspectj.xml" />

8.在專案中經常這樣得到泛型類:

1. private Class<T> entityClass = (Class<T>) ((ParameterizedType) getClass()  
2.             .getGenericSuperclass()).getActualTypeArguments()[0];  

1. private Class<T> entityClass = (Class<T>) getSuperClassGenricType(this
2.             .getClass(), 0);  
3. publicstatic Class<?> getSuperClassGenricType(Class<?> clazz, int index)  
4.             throws IndexOutOfBoundsException {  
5.         Type genType = clazz.getGenericSuperclass();  
6.         if (!(genType instanceof ParameterizedType)) {  
7.             return Object.class;  
8.         }  
9.         Type[] params = ((ParameterizedType) genType).getActualTypeArguments();  
10.         if (index >= params.length || index < 0) {  
11.             return Object.class;  
12.         }  
13.         if (!(params[index] instanceof Class<?>)) {  
14.             return Object.class;  
15.         }  
16.         return (Class<?>) params[index];  
17.     }  

1. <beanid="quartzScheduler"class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
2.                 <propertyname="exposeSchedulerInRepository"value="true"/>
3.                 ...  
4.         </bean>

1. <filter>
2.                 <filter-name>monitoring</filter-name>
3.                 <filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
4.                 <init-param>
5.                         <param-name>log</param-name>
6.                         <param-value>true</param-value>
7.                 </init-param>
8.         </filter>

擴充套件部分:增加訪問許可權校驗

public class MiaoshaMonitoringFilter extends MonitoringFilter {  
   
    protected boolean isRequestAllowed(HttpServletRequest httpRequest) {  
        HttpSession session = httpRequest.getSession();  
        if (session == null) {  
            return false;  
        }  
        User user = (User) session.getAttribute(UserConstants.SEESSION_USER);  
        if(user==null){  
            return false;  
        }  
        return user.isAdmin();  
    }  
}
