解决springboot和jersey结合后，使得uber.jar启动失败的问题

问题：

某一天把spring-boot从1.3.6版本升级到1.4.3版本，然后在使用 java -jar uber.jar 运行启动项目的时候会出现

的异常

环境

springboot 1.5.2
jersey 2.25.1

原因

spring-boot升级到1.4+ 以后，spring-boot专门用来打包的maven plugin对目录结构进行了改变，如果使用了jersey来代替springmvc作为restful的方案，然后并且自己在生成的JerseyConfig类里面，通过 package()函数来指定要扫描的包的路径的话，会导致找不到对应的路径，从而导致了出现java.io.FileNotFoundException 的异常

解决

网上一搜， 果然有很多相关的提问， 其中官方网站的升级wiki里面，也说了这个问题，并且给出了解决方案：
http://docs.spring.io/spring-boot/docs/1.5.x/reference/htmlsingle/#howto-extract-specific-libraries-when-an-executable-jar-runs

但是，按照这个方案进行配置，修改了相关的jar的坐标，但是没有效果（可能是我配置错误，如果有人知道如何通过配置，麻烦告知，十分感谢）

然后没有办法，只能找其他的解决方案

既然是 package()函数来指定扫描包的时候找不到对应的路径，那就替换这个方法，最终使用了

ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);
    // add more annotation filters if you need
    scanner.addIncludeFilter(new AnnotationTypeFilter(Path.class));
    scanner.addIncludeFilter(new AnnotationTypeFilter(Provider.class));
    this.registerClasses(scanner.findCandidateComponents(scanPackage).stream()
        .map(beanDefinition -> ClassUtils
            .resolveClassName(beanDefinition.getBeanClassName(), this.getClassLoader()))
        .collect(Collectors.toSet()));

来替换了传统的 package() 的方式，然后打包、运行。 可以看到项目成功启动了，并且简单的接口也可以访问了。

不过接下来需要进一步验证是否能在其他环境正常运行。
