Druid工具配置使用

一、 配置maven

<!-- mysql数据库连接池 pool --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.8</version> </dependency>

二、自定义DataSourceFactory类, 用来封装第三方DataSource

import org.apache.ibatis.datasource.unpooled.UnpooledDataSourceFactory; import com.alibaba.druid.pool.DruidDataSource; public class DruidDataSourceFactory extends UnpooledDataSourceFactory{ public DruidDataSourceFactory(){ this.dataSource = new DruidDataSource(); } }

三、配置mybatis.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <environments default="development"> <environment id="development"> <transactionManager type="JDBC"/> <dataSource type="com.****.***.web.DruidDataSourceFactory"> <property name="url" value="${jdbc_url}" /> <property name="username" value="${jdbc_username}" /> <property name="password" value="${jdbc_password}" /> <!-- 配置初始化大小、最小、最大 --> <property name="initialSize" value="1" /> <property name="minIdle" value="1" /> <property name="maxActive" value="20" /> <!-- 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="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="validationQuery" value="SELECT 'x'" /> <property name="testWhileIdle" value="true" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <!-- 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" /> </dataSource> </environment> </environments> <mappers> <package name="com.***.****.entity" /> </mappers> </configuration>

四、配置访问路径(web.xml)

<!-- druid监控 --> <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>

当然还可以配置一些过滤条件
