springboot+maven 多模块项目中引入多数据源dynamic-datasource问题

Question

原有springboot+maven多模块项目中，想增加获取另一个数据库的数据，于是增加了dynamic-datasource

的配置，如下：

主pom.xml中增加配置：

      <dependency>
          <groupId>com.baomidou</groupId>
          <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
          <version>2.5.7</version>
      </dependency>

启动类中增加：

 EnableTransactionManagement
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableScheduling
@MapperScan(basePackages = {"com.xxx.mapper"})
public class RapidoRestApplication extends SpringBootServletInitializer {

yml配置文件如下：

datasource:
    dynamic:
      ##默认的数据源
      primary: master
      datasource:
        master: #唯一标识  你原来的数据源放在这里个里面
          url: jdbc:mysql://192.168.****:3306/rap?autoReconnect=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&&useSSL=false
          username: rap
          password: 123456
          type: com.alibaba.druid.pool.DruidDataSource
          driverClassName: com.mysql.cj.jdbc.Driver  #这是驱动8.0的，以前版本的记得换
        s_log: #唯一标识 日志数据源
          url: jdbc:mysql://10.12.0.10:3306/resdb?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2b8
          username: root
          password: 123456
          type: com.alibaba.druid.pool.DruidDataSource
          driverClassName: com.mysql.cj.jdbc.Driver #这是驱动8.0的，以前版本的记得换
    filters: stat
    maxActive: 200
    initialSize: 30
    maxWait: 60000
    minIdle: 10
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: select 'x'
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    maxOpenPreparedStatements: 20

配置完成后，启动服务报错，如下：

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
