继上篇DruidDataSource源码分析之后 , 公司又要求做一个Druid的数据库监控 , 以及spring监控 , 研究一小时 , 总结出了一点经验 , 特此贴出来分享一下
一 . 利用Druid Monitor监控JavaWeb项目
1. 首先配置数据源
xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop

http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init"
destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@192.168.102.93:1521:mydb1" />

<property name="validationQuery" value="SELECT 1 FROM DUAL" />

<property name="testOnReturn" value="false" />
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize" value="20" />
<property name="filters" value="stat,wall,log4j" />
<property name="proxyFilters">

property>
bean>
<aop:config proxy-target-class="true">
<aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" />
aop:config>
beans>
2 . 配置web.xml
<filter> <filter-name>DruidWebStatFilterfilter-name> <filter-class>com.alibaba.druid.support.http.WebStatFilterfilter-class> <init-param> <param-name>exclusionsparam-name> <param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*param-value> init-param> <init-param> <param-name>sessionStatMaxCountparam-name> <param-value>1000param-value> init-param> <init-param> <param-name>profileEnableparam-name> <param-value>trueparam-value> init-param> <init-param> <param-name>principalSessionNameparam-name> <param-value>users.usernameparam-value> init-param> filter> <servlet> <servlet-name>DruidStatViewservlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServletservlet-class> <init-param> <param-name>allowparam-name> <param-value>128.242.127.1/24,127.0.0.1param-value> init-param> <init-param> <param-name>denyparam-name> <param-value>192.168.1.118param-value> init-param> <span style="white-space:pre"> span><init-param> <span style="white-space:pre"> span><param-name>resetEnableparam-name> <span style="white-space:pre"> span><param-value>falseparam-value> <span style="white-space:pre"> span>init-param> <span style="white-space:pre"> span> <span style="white-space:pre"> span><init-param> <param-name>loginUsernameparam-name> <param-value>druidparam-value> init-param> <init-param> <param-name>loginPasswordparam-name> <param-value>druidparam-value> init-param> servlet> <servlet-mapping> <servlet-name>DruidStatViewservlet-name> <url-pattern>/druid/*url-pattern> servlet-mapping>
3 . 配置好web.xml之后，启动自己的JavaWeb服务，访问一下地址就可以看到Druid的监控界面。比如我在这里的访问地址是：http://web4.bj1:8119/druid/index.htm
4 . 输入用户名密码(druid/druid)就可以进入监控页面。
二 . 监控JavaSE项目 ( 使用druidStat.sh 这个命令脚本在Git源码的druid\src\main\scripts目录下)
首先贴出脚本内容
1 . druidStat.sh
#!/bin/sh
if [ -z "$JAVA_HOME" ] ; then
echo "Error: JAVA_HOME is not defined."
exit 1
fi
"$JAVA_HOME/bin/java" -Dfile.encoding="UTF-8" -cp "./druid-0.2.6.jar:$JAVA_HOME/lib/tools.jar" com.alibaba.druid.support.console.DruidStat $@
2 . druidStat.bat
@echo off

set _RUNJAVA="%JAVA_HOME%\bin\java.exe"
set _TOOLSJAR="%JAVA_HOME%\lib\tools.jar"
%_RUNJAVA% -classpath "./druid-0.2.6.jar;%_TOOLSJAR%" com.alibaba.druid.support.console.DruidStat %*
3 . 有了这个脚本就可以在服务器上查看监控信息了 , 只修要修改druid的jar包的路径和版本号.下面举个例子 , 用 sh druidStat.sh -help即可一目了然的看到使用方法 , 具体就不描述了
