尝试搭建多模块项目，项目本来一切就绪，编译上已经不存在错误了，但是在启动时还是报了一个错
错误详情
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
上网寻找解决方法，看到大概这个错误发生原因是数据源配置存在问题，但是我yml中的数据源应该没有啥问题，因为这在我另一个单模块项目中启动没有报错，这个是我yml的配置：
spring:
#配置数据源
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/longcaiuserbook?characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true&useUnicode=true&useSSL=false
username: root
password: root

#配置mybatis
mybatis:
#配置mapper.xml所在路径
mapper-locations: classpath*:/mapping/*.xml,classpath*:pmp/mapper/*/*.xml
# 配置映射类所在的包名：
type-aliases-package: com.cjsg.property.**.entity
server:
port: 62
这个是我的启动类代码
package com.cjsg.testmultiplemodule;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@SpringBootApplication
@ServletComponentScan
@MapperScan("com.cjsg.**.dao")
public class TestMultipleModuleApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(TestMultipleModuleApplication.class, args);
}
}
这是我的主模块的pom依赖相关：

这个是我的目录结构：
试了很多方法尝试解决，网上搜到的修改pom冲突依赖，给启动类
@SpringBootApplication加(exclude = DataSourceAutoConfiguration.class)，给pom中的build引入yml路径之类的，但是都不好使，希望各位帮忙看一下，可能问题出在哪！感谢！
