我试图让Spring Boot 1.5.7与Hibernate一起使用Hikari CP。我在日志中得到这个：
0-Apr-2018 14:07:59.544 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file

这重复了大约5次，我认为这不是巧合是我告诉Hikari开始的最小连接。这是相关的application.properties部分：
# -- Hibernate / JPA

spring.datasource.url=jdbc:mysql://xxxx:3306/gridunity?useSSL=false

spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext
这是相关的POM部分：

现在我通过MySql测试了DB URL，名称和密码，所以我知道不是它。
任何想法？

有一条线说Hikara开始了：
