druid 数据源配置
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="url" value="${ds1.url}" /> <property name="username" value="${ds1.username}" /> <property name="password" value="${ds1.password}" /> <!-- 配置监控统计拦截的filters,去掉后监控界面sql无法统计 --> <property name="filters" value="stat" /> <!-- 配置初始化大小、最小、最大 --> <property name="maxActive" value="20" /> <property name="initialSize" value="1" /> <property name="minIdle" value="1" /> <!-- 配置获取连接等待超时的时间 --> <property name="maxWait" value="60000" /> <!-- 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="3000" /> <!-- 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="validationQuery" value="SELECT ‘x‘" /> <property name="testWhileIdle" value="true" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <!-- 打开PSCache,并且指定每个连接上PSCache的大小 --> <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="20" /> </bean>
此时已经可是使用此数据源了
要查看.../proname/druid/ 须web.xml中添加 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>
此时可访问druid管理了,这里可以配置过滤,像这样:
<servlet> <servlet-name>DruidStatView</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> <init-param> <param-name>allow</param-name> <param-value></param-value> </init-param> <init-param> <param-name>deny</param-name> <param-value>192.168.146.1</param-value> </init-param> <init-param> <param-name>principalSessionName</param-name> <param-value>session.user</param-value> </init-param> <init-param> <param-name>principalCookieName</param-name> <param-value>cookies.user</param-value> </init-param> </servlet>
但是现在druid 下有些标签没数据信息:web.xml下继续添加:
<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>
到此可监控所有的请求了;
