我尝试通过两者来创建 jar

mvn clean package

和

mvn clean install spring-boot:repackage

然后我通过 java -jar -DParamName="someParam" 运行 jar

我在这里做错了什么？我是春天的新手。任何帮助将不胜感激。

标签： java spring maven spring-boot jar

【解决方案1】：

您的 pom.xml 中有 spring-boot-starter-jersey。你得到的错误是/BOOT-INF/classes (No such file or directory)。这是球衣的问题，它不适用于 spring-boot fat jar。请参考this 和this 了解更多详情。要解决此问题，您必须将应该由 jersey 扫描的类打包在一个 jar 中，并按照 Spring-Boot 文档Extract specific libraries when an executable jar runs

中给出的方式提取该 jar

【讨论】：

如何将jersey应该扫描的类打包到jar中？你能举个例子吗？

【解决方案2】：

@abaghel 的答案有正确的解释，并且可以说是最好的解决方案。

由于 Jersey 的扫描步骤失败了，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");
}

与

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

（使用 Spring Boot 2.1.3 测试）

我的代码中有大约 25 个 Jersey 资源类需要注册。这突出了这种方法的缺点，即必须保持显式注册。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，显式注册有时可能就足够了。

【解决方案3】：

添加到@Bampfer 的答案，因为 Googleing 把我带到了这里。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@JaxRsResource，您可以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"; }
}

然后我使用了这篇帖子中的 spring 的组件扫描 api：Scanning Java annotations at runtime 并使用我的自定义注释注册了我找到的组件并调用了 register 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。

我通过替换来解决这个问题：

public class JerseyResourceConfig extends ResourceConfig {
    public JerseyResourceConfig() {
        packages("com.mydomain.resource");
    }
}

与

public class JerseyResourceConfig extends ResourceConfig {
    public JerseyResourceConfig(@Context ServletContext context) {
        WebApplicationContext appCtx = WebApplicationContextUtils.getWebApplicationContext(context);
        registerInstances(new HashSet(appCtx.getBeansWithAnnotation(Path.class).values()));
    }
}

【讨论】：

当我尝试这个时，我得到了Could not autowire: No beans of of 'ServletContext' type found
