这是Tomcat版本：

Apache Maven version 3.6.3

编译之后（用Maven），一切看起来都很好，没有构建错误，构建了war文件，一切都很好，就像以前的任何其他构建一样。只有现在，我尝试命中的任何endpoint都返回404，如果我移除'spring-boot-starter-jdbc'依赖项，则全部返回正常。

没有依赖项得日志：

我看到日志中提到了“数据源”，这是我在application.properites文件中的内容：

spring.datasource.url=jdbc:sqlserver://some-server.net;databaseName=somedbname
spring.datasource.username=serverusername
spring.datasource.password=1346794613

3. Connect to SQL Server with Spring JDBC
4. Connect to SQL Server with Spring Data JPA

还有人经历过这种事吗？会有什么问题？

提前道谢。

Spring MVC（Springboot）和许多其他MVC框架共享相同的概念，其中控制器(C)与模型(M)严格分离。因此，任何持久化模块JDBC都不太可能与您的控制器发生冲突。在你的问题中,

只是现在，我尝试命中的任何端点都返回404

我只能假设应用程序在这个场景中甚至没有上手。

package net.codejava;
 
import org.springframework.data.jpa.repository.JpaRepository;
 
@Repository
public interface CustomerRepository extends JpaRepository<Customer, Long> {
 
}

因此，它变成了一个Spring Bean，您可以在某个地方进一步autowire。

更新：在检查了您刚刚发布的stacktrace之后，我注意到驱动程序类是这里的问题所在。

Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: 
Factory method 'dataSource' threw exception; nested exception is 
org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: 
Failed to determine a suitable driver class

请参见未能确定合适的驱动程序类？它建议您定义驱动程序类。

spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
# or
# spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
