配置配置DruidDataSource

1JDBC直连数据配置项

使用cmd进入对应的druid-1.0.4.jar包所在路径；再根据密码执行上述命令后获取密文

java -cp druid-1.0.4.jar com.alibaba.druid.filter.config.ConfigTools PAAAWORD

2修改spring-db.xml的dataSource为Druid配置

id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">

        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />

        

       

        <property name="url" value="jdbc:oracle:thin:@(description=(address=(host=192.168.1.110)(protocol=tcp)(port=21521))(FAILOVER=on)(LOAD_BALANCE=yes)(connect_data=(SERVER = DEDICATED)(service_name=test)(failover_mode=(type=select)(method=basic)(RETIRES = 20)(DELAY = 15))))" />

        

        <property name="username" value="" />

        <property name="password" value="" />                    

        <property name="filters"  value="config,stat" />

        <property name="connectionProperties" value="config.decrypt=true;druid.stat.slowSqlMillis=3000;druid.stat.logSlowSql=true;druid.stat.mergeSql=true" />

        

        <property name="initialSize" value="20" />

        <property name="minIdle"     value="20" />

        <property name="maxActive"   value="50" />

        <property name="maxWait"     value="60000" />

        

        <property name="timeBetweenEvictionRunsMillis" value="300000" />

        

        <property name="minEvictableIdleTimeMillis"    value="300000" />

        

        <property name="validationQueryTimeout" value="300000" />

        <property name="validationQuery" value="SELECT sysdate from dual" />

        <property name="testWhileIdle"   value="true" />

        <property name="testOnBorrow"    value="false" />

        <property name="testOnReturn"    value="false" />

        

        

        <property name="poolPreparedStatements" value="true" />

        <property name="maxPoolPreparedStatementPerConnectionSize" value="50" />

3配置web.xml

Tomcat JNDI数据源配置项

在Tomcat使用JNDI配置DruidDataSource，在/conf/context.xml中，在中加入如下配置：

<Resource name="jdbc/druid-test" factory="com.alibaba.druid.pool.DruidDataSourceFactory"

auth="Container" 

type="javax.sql.DataSource" 

maxActive="100" 

maxIdle="30"

maxWait="10000" 

url="jdbc:derby:memory:tomcat-jndi;create=true" 

     filters="stat" 

/>

DruidDataSource配置项

和DBCP几乎一样，迁移十分方便

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> 

     <property name="url" value="${jdbc_url}" />

     <property name="username"><value>${jdbc_user}value>property>

     <property name="password" value="${jdbc_password}" />

 

     <property name="filters"><value>statvalue>property>

 

     <property name="maxActive"><value>20value>property>

     <property name="initialSize"><value>1value>property>

     <property name="maxWait"><value>60000value>property>

     <property name="minIdle"><value>1value>property>

 

     <property name="timeBetweenEvictionRunsMillis"><value>60000value>property>

     <property name="minEvictableIdleTimeMillis"><value>300000value>property>

 

     <property name="validationQuery"><value>SELECT 'x'value>property>

     <property name="testWhileIdle"><value>truevalue>property>

     <property name="testOnBorrow"><value>falsevalue>property>

     <property name="testOnReturn"><value>falsevalue>property>

 

     <property name="poolPreparedStatements"><value>truevalue>property>

     <property name="maxOpenPreparedStatements"><value>20value>property>

 bean>

为了避免日志文件多大，

造成问题协查不便以及存储资源浪费，强烈建议把慢SQL监控输出关闭。

druid.stat.logSlowSql=false;

对于配置为true时超出设置阈值的SQL会以ERROR信息显示：
