接入HikariCP遇到问题
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:
