Cannot create JDBC driver of class '' for connect URL 'jdbc:mysql://127.0.0.1:3306/test'

原來的配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">


    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource">
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/test"></property>
　　　　 <!--<property name="url" value="jdbc:mysql://localhost/test?user=root&password=root" />-->
        <property name="username" value="root"></property>
        <property name="password" value="root"></property>
    </bean>
</beans>

 

項目部署時沒有報錯，在進行增刪改查時報錯：Cannot create JDBC driver of class '' for connect URL 'jdbc:mysql://127.0.0.1:3306/test'

錯誤信息的意思是沒有找到driver，仔細一看，在dataSource中少了driver這個屬性，加上即可，正確配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">


    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource">
        <!--添加Driver-->
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/test"></property>
        <property name="username" value="root"></property>
        <property name="password" value="xuexi"></property>
    </bean>
</beans>
