看不出具体是哪里出了错，后来经过同事提醒，配置文件中数据库密码有特殊字符

spring:
  datasource:
     driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver
     url: jdbc:sqlserver://127.0.0.1:1433;DatabaseName=sjdsx;autoReconnect=true
     username: sa
     password: !+r@sSsMGC1@@i25*w
  jpa:
     database: sql_server
     hibernate:
       ddl-auto: none
     show-sql: true
     database-platform: org.hibernate.dialect.SQLServer2008Dialect

需要加上引号：

     driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver
     url: jdbc:sqlserver://127.0.0.1:1433;DatabaseName=sjdsx;autoReconnect=true
     username: sa
