我试图创建一个使用Hibernate 5和Postgres 9的Spring Boot应用程序。现在我遇到了如下错误:
Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
- Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
- Bean method 'dataSource' not loaded because @ConditionalOnBean (types: org.springframework.boot.jta.XADataSourceWrapper; SearchStrategy: all) did not find any beans
虽然,我已经添加了 spring.datasource.* 属性:
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=root

有什么想法吗?在大多数教程中,一切都非常标准和简单,似乎我错过了一些小细节..
