我尝试使用依赖项创建简单的 webapps springboot：web、postgresql、jdbc、vaadin。开始运行我的应用程序时，应用程序将无法启动并抛出异常。异常告诉“..没有 JdbcTemplate 类型的合格 bean”。stackoverflow 中的一些建议添加工件spring-boot-starter-jdbc，但我的 pom 已经做到了，但仍然无法正常工作。

在我的配置下面

src/main/resources/application.properties:

spring.datasource.url=jdbc:postgresql://localhost:5432/sehati
spring.datasource.username=sehati
spring.datasource.password=password
