Cannot load JDBC driver class 'com.mysql.jdbc.Driver

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException: ### Error updating
database. Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver '### Cause: org.springframework.jdbc.CannotGetJdbcConnectionException:
Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver '

解决：

applicationContext.xml中是

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

        destroy-method="close">

        <property name="driverClassName" value="${jdbc.driver}" />

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

        <property name="username" value="${jdbc.username}" />

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

        <property name="maxActive" value="30" />

        <property name="maxIdle" value="5" />

    </bean>

db.properties中的顺序弄错了

应该和applicationContext中一致
