Spring Boot创建DataSource时遇到的错误:No supported DataSource type found

在对Spring Boot进行DataSource配置的时候遇到一个错误

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'testDataSource' threw exception; nested exception is java.lang.IllegalStateException: No supported DataSource type found

原因是在使用DataSourceBuilder时需要在classpath里指定以下三个中的任意一个:

1.       COMMONS-DBCP

2.       TOMCAT-JDBC

3.       HIKARICP


于是在pom.xml添加了HiKariCP的依赖

		<dependency>
			<groupId>com.zaxxer</groupId>
			<artifactId>HikariCP</artifactId>
			<version>3.2.0</version>
		</dependency>


错误就没有了
