SSM框架配置Druid数据库连接池，启用监控

SSM框架配置Druid数据库连接池，启用监控

• 1，应用pom包
• 2，web.xml文件配置信息
• 3，数据库连接配置文件

1，应用pom包

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.10</version>
</dependency>

2，web.xml文件配置信息

<filter>

<!-- 用于采集web-jdbc关联监控的数据 -->
<filter-name>DruidWebStatFilter</filter-name>
<filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>

<init-param>
<!-- 排除不需要监控的url -->
<param-name>exclusions</param-name>
<param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</param-value>
</init-param>
<init-param>
<!-- 缺省sessionStatMaxCount是1000个 -->
<param-name>sessionStatMaxCount</param-name>
<param-value>1000</param-value>
</init-param>
<init-param>
<!--开启session统计功能 --> -
<param-name>sessionStatEnable</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<!--配置principalSessionName，使得druid能够知道当前的session的用户是谁-->
<param-name>principalSessionName</param-name>
<param-value>session_user_key</param-value>
</init-param>
<init-param>
<!--配置profileEnable能够监控单个url调用的sql列表-->
<param-name>profileEnable</param-name>
<param-value>true</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>DruidWebStatFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置 Druid 监控信息显示页面 -->
<servlet>
<servlet-name>DruidStatView</servlet-name>
<servlet-class>com.config.CustomStatViewServlet</servlet-class>
<init-param>
<param-name>allow</param-name>
<param-value>127.0.0.1</param-value>
</init-param>
<init-param>
<param-name>resetEnable</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>loginUsername</param-name>
<param-value>zxzhelloworld</param-value>
</init-param>
<init-param>
<param-name>loginPassword</param-name>
<param-value>abcd1234</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DruidStatView</servlet-name>
<url-pattern>/druid/*</url-pattern>
</servlet-mapping>

3，数据库连接配置文件

<bean id="datasource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/hellodruid?autoReconnect=true&amp;characterEncoding=utf-8&amp;allowMultiQueries=true" />
<property name="username" value="root" />
<property name="password" value="root" />
<property name = "filters" value = "stat" />
<property name="validationQuery" value="SELECT 1" />
<!-- 最大并发连接数 -->
<property name="maxActive" value="30" />
<!-- 初始化连接数量 -->
<property name="initialSize" value="5" />
<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="60000" />
<!-- 最小空闲连接数 -->
<property name="minIdle" value="10" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="maxOpenPreparedStatements" value="20" />
<!-- 打开removeAbandoned功能 -->
<property name="removeAbandoned" value="true" />
<!-- 1800秒，也就是30分钟 -->
<property name="removeAbandonedTimeout" value="1800" />
<!-- 关闭abanded连接时输出错误日志 -->
<property name="logAbandoned" value="true" />

<!-- 若需要mybatis的批量sql需配置     不配置则报错:nested exception is java.sql.SQLException: sql injection violation, multi-statement not allow-->
<property name="proxyFilters">
<list>
<ref bean="wall-filter"/>
</list>
</property>

</bean>
<!-- 若需要mybatis的批量sql需配置 -->
<bean id="wall-filter" class="com.alibaba.druid.wall.WallFilter">
<property name="config" ref="wall-config" />
</bean>

<bean id="wall-config" class="com.alibaba.druid.wall.WallConfig">
<property name="multiStatementAllow" value="true" />
</bean>
