老Tomcat项目在接入HikariCP时遇到报错：

Caused by: java.lang.AbstractMethodError: com.mysql.jdbc.Connection.isValid(I)Z

解决思路：

先贴出 pom.xml,

<properties>
    <HikariCP>2.4.13</HikariCP>
</properties>
<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP-java7</artifactId>
    <version>${HikariCP}</version>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.0.5</version>
    <scope>runtime</scope>
</dependency>

 配置数据源

<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
            <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
            <property name="jdbcUrl" value="jdbc:mysql://finance.fd.com:3306/finance_syscnf"/>
            <property name="username" value="CC_dev"/>
            <property name="password" value="hvo3sl234"/>
            <property name="connectionTestQuery" value="select 1"/>
</bean>

 如果不添加 <property name="connectionTestQuery" value="select 1"/>, 那么连接池初始化会报错:
