我有一个Spring启动应用程序，当通过intellij运行时工作正常。但是当我从jar运行它时，我得到了下面的异常。

我试着用两个

mvn clean package

和

mvn clean install spring-boot:repackage

然后我通过java运行jar-jar-DParamName="有些Param"

我做错了什么？我是Spring的新手。任何帮助都将不胜感激。

为了补充@Bampfer的答案，因为谷歌把我带到这里。这是一种不必在单独的模块中解压资源并进行动态组件扫描的方法。

创建一个自定义注释，将其放在任何资源类上。

public @interface JaxRsResource {
}

@Named
@JaxRsResource
@Path("/my/api/path")
public class MyResource {
    @GET
    public String helloWorld() { return "Hello World"; }
}

然后，我使用了这篇文章中的Spring组件扫描api：在运行时扫描Java注释，并用我的自定义注释注册了我找到的组件，并调用了寄存器函数。

@Configuration
public class JaxrsApplication extends ResourceConfig {

    private final Logger logger = LoggerFactory.getLogger(JaxrsApplication.class);

    public JaxrsApplication() {

        final ClassPathScanningCandidateComponentProvider scanner =
                new ClassPathScanningCandidateComponentProvider(false);

        scanner.addIncludeFilter(new AnnotationTypeFilter(JaxRsResource.class));

        for (final BeanDefinition resourceBean : scanner.findCandidateComponents("my.base.package")) {
                try {
                    final Class resourceClass = getClass().getClassLoader().loadClass(resourceBean.getBeanClassName());
                    register(resourceClass);
                } catch (final ClassNotFoundException e) {
                    logger.error(String.format("Unable to load Jax-RS resource {}.", resourceBean.getBeanClassName()), e);
                }
            }
        }
    }
}

注意：您必须从类加载器加载类，并将类对象传递给register（）。如果只将类名作为字符串传递给register方法，则不会加载资源。

@阿巴格尔的答案有正确的解释，也可以说是最好的解决方案。

由于Jersey的扫描步骤是失败的，另一种解决方法是显式注册每个资源。我替换了这个：

@Component
public JerseyConfig() extends ResourceConfig {
    packages("com.mydomain.resource");
}

具有

@Component
public JerseyConfig() extends ResourceConfig {
    register(TimeResource.class);
    register(SpaceResource.class);
    // etc.
}

（使用Spring Boot 2.1.3测试）

我的代码有大约25个泽西的资源类要注册。这突出了这种方法的缺点，即必须维护显式注册。不会自动找到新的资源类，并且可能会遇到令人困惑的错误。

另一方面，您不需要拆分项目。因此，显式注册有时可能已经足够好了。

您的pom.xml.中有spring-boot-starter-jersey您得到的错误是/BOOT-INF/class（没有这样的文件或目录）。这是jersey的问题，它不能很好地与spring-boot胖jar配合使用。请参考这个和这个以获取更多详细信息。为了解决这个问题，您必须将应该由jersey扫描的类打包到jar中，并按照Spring-Boot留档中给出的方式提取jar当可执行jar运行时提取特定库
