Question

我的自动配置文件在Spring-Boot应用程序中不起作用。我在下面附上我的配置应用程序文件：

@Configuration
@EnableAutoConfiguration
@ComponentScan
@SpringBootApplication
@EnableScheduling
public class Application {

  public static void main(String[] args) {
      SpringApplication springApplication=new SpringApplication(Application.class);
      System.out.println("Spring Core Version:- " + SpringVersion.getVersion());
      springApplication.run(args);

  }
}

抛出异常如下。我该如何解决？

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

Answer 1

我自己解决了。

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.0.7.Final</version>
</dependency>

Answer 2

我从@Component添加了import org.springframework.stereotype.Component注解，问题得以解决。

Answer 3

在我看来，找不到您的Hibernate库（NoClassDefFoundError：org / hibernate / boot / archive / scan / spi / ScanEnvironment，如上所示）。

尝试检查Hibernate核心是否作为依赖项放入：

    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-core</artifactId>
      <version>5.0.11.Final</version>
      <scope>compile</scope>
    </dependency>

Answer 4

就我而言，我在项目中包括了jdbc api依赖项，因此未打印“ Hello World”。删除以下依赖项后，它就像一个魅力。

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>

启动ApplicationContext时出错。要显示自动配置报告，请在启用“debug”的情况下重新运行应用程序
