解决方法:

把application.xml的spring.datasource.《前缀》.url改成spring.datasource.《前缀》.jdbc-url即可

问题是jdbcurl缺失driverClassName,我没有配置jdbcurl?回去看application.xml的数据源配置。发现我配置的是spring.datasource.spring.url。那么问题来了,之前单数据源的时候就可以用url配置,为什么多数据源就要用jdbc-url呢?等有空在仔细进入源码看看吧。

环境:

application.xml

logging.config=classpath:logging-config.xml    #这里是多数据源  spring.datasource.spring.url=jdbc:mysql://localhost:3306/spring?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC  spring.datasource.spring.username=root  spring.datasource.spring.password=root  spring.datasource.spring.driver-class-name=com.mysql.jdbc.Driver    spring.datasource.springboot.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC  spring.datasource.springboot.username=root  spring.datasource.springboot.password=root  spring.datasource.springboot.driver-class-name=com.mysql.jdbc.Driver      # REDIS (RedisProperties)  # Redis数据库索引(默认为0)  spring.redis.database=0  # Redis服务器地址  spring.redis.host=192.168.203.1  # Redis服务器连接端口  spring.redis.port=6379  # Redis服务器连接密码(默认为空)  spring.redis.password=  # 连接池最大连接数(使用负值表示没有限制)  spring.redis.jedis.pool.max-active=8  # 连接池最大阻塞等待时间(使用负值表示没有限制)  spring.redis.jedis.pool.max-wait=200ms  # 连接池中的最大空闲连接  spring.redis.jedis.pool.max-idle=8  # 连接池中的最小空闲连接  spring.redis.jedis.pool.min-idle=0  # 连接超时时间(毫秒)  spring.redis.timeout=2000ms

多数据源配置类:
