此时项目建好了，但是启动项目会报错，因为配了postgresql，必须配置链接到数据库

postgresql 配置application.yml文件配置

spring:
      datasource:
        driver-class-name: org.postgresql.Driver
        url: jdbc:postgresql://localhost:5432/firstproject
        username: postgres
        password: 123456
    
      # 解决jpa未被使用启动报错：org.postgresql.jdbc.PgConnection.createClob() 方法尚未被实作
      jpa:
        properties:
          hibernate:
            temp.use_jdbc_metadata_defaults: false

application.properties文件配置，两个配置文件效果一致

spring.datasource.driver-class-name=org.postgresql.Driver
    spring.datasource.url=jdbc:postgresql://localhost:5432/firstproject
    spring.datasource.username=postgres
    spring.datasource.password=123456
    
    #解决jpa未被使用启动报错：org.postgresql.jdbc.PgConnection.createClob() 方法尚未被实作
    spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false

创建数据库

注意配置文件与下图中的配置要对应
