解決辦法

    將配置文件中的url修改成jdbc-url  代碼以下java

spring:
  datasource:
    test1:
      driver-class-name: com.mysql.jdbc.Driver
      username: root
      password: root
      jdbc-url: jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8
    test2:
      driver-class-name: com.mysql.jdbc.Driver
      username: root
      password: root
      jdbc-url: jdbc:mysql://localhost:3306/springboot?characterEncoding=UTF-8
