applicationContext.xml

<!-- test环境 -->
    <beans profile="test">
    
        <context:property-placeholder ignore-unresolvable="true"
            location="classpath*:config/jdbc.test.properties" />
                
        <!--阿里巴巴druid,高效、功能强大、可扩展性好,便于sql监控分析-->    
        <bean id="mysqlDataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">  
            <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="5" />
            <property name="minIdle" value="5" />
            <property name="maxActive" value="20" />
            <!-- 配置获取连接等待超时的时间 -->
            <property name="maxWait" value="60000" />
        
            <!--打开PSCache,并且指定每个连接上PSCache的大小 ,Oracle,把poolPreparedStatements配置为true,mysql可以配置为false。分库分表较多的数据库,建议配置为false-->
            <property name="poolPreparedStatements" value="false" />
            <property name="maxPoolPreparedStatementPerConnectionSize" value="20" />
        
            <!-- 开启Druid的监控统计功能 -->
            <property name="filters" value="stat,config" />
            <!-- 开启数据库密码解密-->
            <property name="connectionProperties" value="config.decrypt=${jdbc.decrypt};config.decrypt.key=${jdbc.publickey}" /> 
            </bean>    
        <!-- 数据源1配置, 使用Tomcat JDBC连接池 -->
        <!-- <bean id="mysqlDataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
            Connection Info
            <property name="driverClassName" value="${jdbc.driver}" />
            <property name="url" value="${jdbc.url}" />
            <property name="username" value="${jdbc.username}" />
            <property name="password" value="${jdbc.password}" />
        
            Connection Pooling Info
            <property name="maxActive" value="${jdbc.pool.maxActive}" />
            <property name="maxIdle" value="${jdbc.pool.maxIdle}" />
            <property name="minIdle" value="0" />
            <property name="defaultAutoCommit" value="true" />
        </bean> -->
        
    </beans>
