解决方法：配置数据源时spring.datasource.url改为spring.datasource.jdbc-url，修改如下：

spring:
 bz-datasource:
    driver-class-name: com.mysql.jdbc.Driver
    jdbc-url: jdbc:mysql://xxx:3306/tnaot_news_bz?useUnicode=true&characterEncoding=UTF-8&useSSL=false
    username: dbuser
    password: asdQWE!@#

 recommend-datasource:
    driver-class-name: com.mysql.jdbc.Driver
    jdbc-url: jdbc:mysql://xxx:3306/tnaot_recommend?useUnicode=true&characterEncoding=UTF-8&useSSL=false
    username: dbuser
    password: asdQWE!@#

 news-datasource:
    username: dbuser
    password: asdQWE!@#
    driver-class-name: com.mysql.jdbc.Driver
    jdbc-url: jdbc:mysql://xxx:3306/mongcent_news?useUnicode=true&characterEncoding=UTF-8&useSSL=false
