jdbcUrl is required with driverClassName错误解决

springboot 升级到2.0之后发现配置多数据源的时候报错：

“jdbcUrl is required with driverClassName.”或者Cause: java.lang.IllegalArgumentException: dataSource or dataSourceClassName or jdbcUrl is required.] with root cause

主要原因是在1.0 配置数据源的过程中主要是写成：spring.datasource.url 和spring.datasource.driverClassName。

而在2.0升级之后需要变更成：spring.datasource.jdbc-url和spring.datasource.driver-class-name即可解决！

springboot2.0配置多数据源：

改为：

server:
  port: 8080
spring:
  main:
    allow-bean-definition-overriding: true
  datasource:
    admin: # sys-admin
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/sys-admin?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8
      username: root
      password: 123456
    order: # sys-order
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/sys-order?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8
      username: root
      password: 123456
