【Spring系列】Spring mvc整合druid

一、pom.xml中添加druid依赖

 <!-- druid -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.0.7</version>
        </dependency>

二、修改SqlSessionFactory中的dataSource引用

<!--2 配置druid数据源 -->
    <bean id="datasource" class="com.alibaba.druid.pool.DruidDataSource">
        <!--驱动类名 -->
        <property name="driverClassName" value="${mysql.driver}" />
        <!-- url -->
        <property name="url" value="${mysql.url}" />
        <!-- 用户名 -->
        <property name="username" value="${mysql.uid}" />
        <!-- 密码 -->
        <property name="password" value="${mysql.password}" />
        <!--初始化连接大小-->
        <property name="initialSize" value="${mysql.initialPoolSize}"/>
        <!--连接池最大使用连接数量-->
        <property name="maxActive" value="${mysql.maxPoolSize}"/>
        <!--连接池最小空间-->
        <property name="maxIdle" value="0"/>
        <!--获取连接最大等待时间-->
        <property name="maxWait" value="60000"/>
        <property name="validationQuery" >
            <value >select 1 from dual</value>
        </property>

        <property name="testOnBorrow" value="false"/>
        <property name="testOnReturn" value="false"/>
        <property name="testWhileIdle" value="true"/>
        <!--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="25200000"/>
        <!--打开removeAbandoned功能-->
        <property name="removeAbandoned" value="true"/>
        <!--1800秒 -->
        <property name="removeAbandonedTimeout" value="1800"/>
        <!--关闭abandoned连接是输出错误日志-->
        <property name="logAbandoned" value="true"/>
        <!--监控数据库-->
        <property name="filters" value="mergeStat"/>
    </bean>

三、web.xml中排除一些不必要的url

 <!-- 经常需要排除一些不必要的url，比如.js,/jslib/等等。配置在init-param中。比如 -->
    <filter>
        <filter-name>DruidWebStatFilter</filter-name>
        <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
        <init-param>
            <param-name>exclusions</param-name>
            <param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>DruidWebStatFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- druid的Servlet -->
    <servlet>
        <servlet-name>DruidStatView</servlet-name>
        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>DruidStatView</servlet-name>
        <url-pattern>/druid/*</url-pattern>
    </servlet-mapping>
