当我在IntelliJ中运行我的项目时它工作正常，服务器启动等但是当我构建我的项目（使用maven）并且我想执行.jar文件时我得到了这些错误：

第一个例外可能是因为在我的SocialConfig类中，我使用“Environment”从application.properties中获取属性，并且没有属性在.jar之外（当它们在jar旁边时也可以获取它）但我不知道其他例外是什么意思......

Application.class：

@SpringBootApplication
public class EnnuiApplication {

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

    @Bean
    public ModelMapper modelMapper(){
        return new ModelMapper();
    }
}

SocialConfig.class：

   @Configuration
public class SocialConfig implements SocialConfigurer {

    public void addConnectionFactories(ConnectionFactoryConfigurer cfConfig, Environment env) {
        cfConfig.addConnectionFactory(new FacebookConnectionFactory(
                env.getProperty("facebook.appId"),
                env.getProperty("facebook.appSecret")));
    }

    @Override
    public UserIdSource getUserIdSource() {
        return null;
    }

    @Override
    public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
        return null;
    }
}

Answer 1

正如JB Nizet指出的那样，问题在于没有提供FacebookConnectionFactory。

目录JAR可以添加到包装中。但是，您应该考虑将依赖项安装到本地Maven存储库并从那里将其提供给项目，而不是将其传递到目录中。

Answer 2

将JAR手动安装到本地Maven存储库中。

第一个解决方案是使用Maven目标install：install-file将JAR手动添加到本地Maven存储库中。插件的使用非常简单，如下所示：

mvn install:install-file -Dfile=<path-to-file>

请注意，我们没有指定要安装的JAR的groupId，artifactId，版本和包装。实际上，由于Maven-install-plugin的版本为2.5，因此可以从可选的pomFile中获取这些信息。

这些信息也可以在命令行中给出：

mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version>

位置：

<path-to-file>: Path to the JAR to install
<group-id>: Group id of the JAR to install
<artifact-id>: Artifact id of the JAR to install
<version>:  Version of the JAR

例如：

mvn install:install-file –Dfile=C:\dev\app.jar -DgroupId=com.roufid.tutorials -DartifactId=example-app -Dversion=1.0

然后您可以通过将这些行添加到pom.xml文件中来将依赖项添加到您的Maven项目中：

<dependency>
    <groupId>com.roufid.tutorials</groupId>
    <artifactId>example-app</artifactId>
    <version>1.0</version>
</dependency>

此解决方案可能非常昂贵。为什么？您必须考虑到更改本地Maven存储库的那一天必须重新安装JAR。再或者，如果有很多人在从事该项目，那么每个人都必须在其本地存储库中安装JAR。必须考虑项目的可移植性。

另一种解决方案是在pom.xml中使用maven-install-plugin，这将在Maven“初始化”阶段安装jar。为此，您必须指定要安装的jar的位置。最好的方法是将JAR放在项目根目录下创建的文件夹中（与pom.xml文件位于同一目录中）。

Spring .jar没有启动
