Java报错：Error creating bean with name 'testController': Injection of resource dependencies failed

报错如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bookRepository' defined in com.sirifeng.testjpa.Mapper.BookRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot resolve reference to bean 'jpaMappingContext' while setting bean property 'mappingContext'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

 

我吐了，de了两个小时的bug，最后发现是数据库的url的一个参数写错了，我写的

spring.datasource.url=jdbc:mysql://localhost:3306/webstore?useUnicode=true&characterEncoding=utf-8&serverTimeZone=UTC


这里的serverTimeZone，写错了，应该是serverTimezone，Z写成大写了，跟这报错没有半毛线关系，对新手来说真的太不友好了啊！！！！

所以写代码的时候，特别是这种配置文件的，一定要仔细检查！！！
