Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfigurat

报错

pom.xml加入了jpa的引用， 项目启动时会去读yml或properties文件里的jdbc配置，没有就报错：Error creating bean with name ‘org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration’: Unsatisfied dependency expressed through constructor parameter 0;

解决方案

只需要加入相应的jar包并把jpa、datasource配好后就可以了：

server:
  port: 80
  servlet:
    context-path: /hv
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/db_test?useSSL=false&serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&allowPublicKeyRetrieval=true
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource

注：上面连接url最后面的allowPublicKeyRetrieval=true必须加上否则有可能会报错：java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
