我在听到很多人的好评后，试图从c3p0切换到HikariCP。我遇到了一个错误。我无法弄清楚我到底做错了什么。 使用的技术：Spring 4，Hibernate 4.3.7，HikariCP 2.4.1，Oracle 11g和hibernate-hikaricp：5.0.2.Final
Spring配置文件：config.xml
<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource"

<property name="connectionTestQuery" value="SELECT 1"/>
<property name="dataSourceClassName" value="oracle.jdbc.pool.OracleDataSource" />
<property name="dataSourceProperties">

java文件：AccountsController.java

try {

String result = usersDAO.validate(jsonData);
