当我尝试构建我的应用程序以将我的项目上传到天蓝色时，我遇到了下一个错误并使用“mvn -e -X -Pproduction -DskipTests clean package”对其进行调试：

[ERROR] Failed to execute goal com.vaadin:vaadin-maven-plugin:22.0.0:build-frontend (default) on project cinema: Could not execute build-frontend goal: Error occured during goal execution: Type [unknown] not presentPlease run Maven with the -e switch (or Gradle with the --stacktrace switch), to learn the full stack trace. org/springframework/context/ApplicationEventPublisherAware: org.springframework.context.ApplicationEventPublisherAware -> [Help 1]

这就是我的 pom.xml 的样子，我认为我没有错过任何依赖或任何东西，我花了一整天的时间试图弄清楚这里发生了什么，谢谢。

知道如何处理这些问题吗？

问题是Application类中有两个不必要的注释

您不需要@EnableJpaRepositories，因为您的包结构是分层正确的。加上这个没有定义包的注释是没有意义的。去掉它。

@EnableAutoConfiguration已经开启@SpringBootApplication。删除这个。

然后在 pom.xml 中有一些问题。

您不应该像这里那样覆盖 Spring Boot 版本：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
    <version>2.3.3.RELEASE</version>
</dependency>

然后您可以删除所有这些依赖项，因为它们已经带有启动器依赖项：

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

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

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

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

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>7.0.1.Final</version>
    </dependency>
    
    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>7.0</version>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-java8</artifactId>
        <version>${hibernate.version}</version>
    </dependency>

我有一个类似的问题。但是，我不能简单地摆脱类上的@EnableJpaRepositories注释，Application因为需要配置一些要扫描的包。但是AppShellConfigurator在一个单独的组件中实现（即不在Application类中）对我来说是诀窍。

所以在我的例子中，这个Application类最终看起来像这样：

@SpringBootApplication(scanBasePackages = { ... })
@EnableJpaRepositories(basePackageClasses = { ... })
...
public class Application extends SpringBootServletInitializer { ... }

单独的AppShellConfigurator实现如下所示：

import org.springframework.stereotype.Component;
import com.vaadin.flow.component.page.AppShellConfigurator;
import com.vaadin.flow.theme.Theme;

@Component
@Theme(MyTheme.THEME_NAME)
public class MyAppShellConfigurator implements AppShellConfigurator { }
