最近使用dbcp2时发现错误：java.lang.AbstractMethodError: com.mysql.jdbc.Connection.isValid(I)Z

网上说要更新mysql-connector.jar可是在我更新之后问题还是没有解决，后来浏览国外的网站发现解决方法了

就是在spring的beans.xml中添加<property name="validationQuery" value="${db.validationQuery}" />配置即可解决问题。

具体配置如下：

beans.xml

<?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:aop="http://www.springframework.org/schema/aop"        xmlns:tx="http://www.springframework.org/schema/tx"        xsi:schemaLocation="http://www.springframework.org/schema/beans                http://www.springframework.org/schema/beans/spring-beans.xsd                http://www.springframework.org/schema/tx                http://www.springframework.org/schema/tx/spring-tx.xsd                http://www.springframework.org/schema/aop                http://www.springframework.org/schema/aop/spring-aop.xsd"><bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">        <property name="driverClassName" value="${db.driverClassName}" />        <property name="url" value="${db.url}" />        <property name="username" value="${db.username}" />        <property name="password" value="${db.password}" />    <property name="validationQuery" value="${db.validationQuery}" />    </bean><bean id="propertyConfigurer"        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="location" value="classpath:jdbc.properties" />    </bean><bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"><property name="dataSource" ref="dataSource"></property></bean><bean id="studentDao" class="cn.edu.whpu.dao.impl.StudentDaoImpl"><property name="jdbcTemplate" ref="jdbcTemplate"></property></bean><bean id="studentService" class="cn.edu.whpu.service.impl.StudentServiceImpl"><property name="studentDao" ref="studentDao"></property></bean></beans>

jdbc.properties
