Druid监控Mybatis不显示SQL问题

hti

一、Web.xml增加如下配置：
1、DruidWebStatFilter。如果没有配置filter信息。session监控，web监控等不可用。没有配置

<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>/static/*,*.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>


2、DruidStatView。如果没有servlet，无法通过web页面查看监控数据。

<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>


二、在Spring中声明Druid数据源，

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="maxActive" value="${db.maxActive}" />
<property name="initialSize" value="${db.initialSize}" />
<property name="maxWait" value="${db.maxWait}" />
<property name="minIdle" value="${db.minIdle}" />
<property name="timeBetweenEvictionRunsMillis" value="${db.timeBetweenEvictionRunsMillis}" />
<property name="minEvictableIdleTimeMillis" value="${db.minEvictableIdleTimeMillis}" />
<property name="testWhileIdle" value="${db.testWhileIdle}" />
<property name="testOnBorrow" value="${db.testOnBorrow}" />
<property name="testOnReturn" value="${db.testOnReturn}" />
<property name="poolPreparedStatements" value="${db.poolPreparedStatements}" />
<property name="maxPoolPreparedStatementPerConnectionSize" value="${db.maxPoolPreparedStatementPerConnectionSize}" />
<property name="filters" value="stat" />
</bean>


注意：<property name="filters" value="stat" />属性，不然无法显示SQL检测信息。
