Question

我正在尝试在heroku上部署一个应用程序并遇到了几个问题。该应用程序正在我的IDE（Intellij）中工作，但当我尝试使用“heroku local -f Procfile.windows”运行它时，我收到此错误：

@EntityScan(basePackages = { "cinemagic.model"})
@EnableScheduling

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/").setCachePeriod(0);
    super.addResourceHandlers(registry);
}

public static void main(String[] args) {
    SpringApplication.run(App.class, args);
}

}

Answer 1

首先让框架使用框架而不是框架。你的依赖是一团糟，你没有使用正确的插件。

首先删除所有插件并替换为spring-boot-maven插件。（另见the reference guide）。

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

接下来清理您的依赖项并使用正确的（Spring Boot托管）版本。

<dependencies>

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

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

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

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

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-jpamodelgen</artifactId>
        <scope>provided</scope>
    </dependency>

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

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>

    <dependency>
        <groupId>org.flywaydb</groupId>
        <artifactId>flyway-core</artifactId>
    </dependency>

    <dependency>
        <groupId>org.assertj</groupId>
        <artifactId>assertj-core</artifactId>
        <version>3.4.1</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
    </dependency>

</dependencies>

最后，您的应用程序类（有些）存在缺陷，您不需要那么多注释，并且您正在扩展Spring Boot配置类。 Spring Boot默认已提供您在重写方法中尝试执行的操作。所以没有必要这样做。另外，只需将App课程放在cinematic顶级包中，其他所有内容都将为您检测。

@SpringBootApplication
@EnableScheduling
public class App 

  public static void main(String[] args) {
      SpringApplication.run(App.class, args);
  }

}

现在重建你的jar并启动它。

注意：主要问题是您没有使用Spring Boot maven插件，但是他自己试图这样做。

Answer 2

转到C：\ Users \ username.m2 \ repository \ org \ springframework \ boot

并删除spring-boot-autoconfiguration并再次构建你的maven。

它会工作它会再次生成。

由于缺少EmbeddedServletContainerFactory bean
