当我使用 Spring Boot 2.7.2 时，一切正常。升级到版本 3.0.0-SNAPSHOT 后，我有

我想部署一个Spring-Boot application具有Service访问JpaRepository它连接到PostgreSQL DB在系统运行时JPA和Hibernate中,指的连接属性src/main/resources/application.properties

当我在Tomcat上部署构建的.WAR时,应用程序无法启动错误日志中给出的错误.

有人可以帮忙解决这个错误的含义吗？

注意:我已经注意到了麻烦点MyServiceImpl和MyRequestBody类,但我没有得到该错误的确切原因,因为我是新来的Spring框架.

我的Spring Boot Starter项目中相关类的定义如下:

Spring Boot应用程序

@SpringBootApplication
@ComponentScan(<root package name under which all subpackages containing relevant classes >)
public class MySpringBootApplication extends SpringBootServletInitializer {

我的Spring-Boot RestController类(自动装配MyService类实例)

@RestController
public class MyController {

    @Autowired
    MyService myService;

我的服务界面(我没有提供任何@Service注释)

public interface MyService {
    //all service method definitions
}

Spring ServiceImpl类,具有在PostgreSQL DB上运行的自动装配存储库实例

@Service("myService")
public class MyServiceImpl implements MyService {

       @Autowired
       private MyRepository …
