@nobodyiam 是的。我刚刚看了，spring-boot-maven-plugin配置了`org.apache.maven.plugins.shade.resource.ServicesResourceTransformer`，而且打包出来的jar都是在lib下面的，SPI能找到这两种实现，因此不会出问题。 有些用户可能用的不是spring-boot-maven-plugin，自己配置了maven-shade-plugin，尤其是一些用于非web场景的可执行jar，在实践中，确实容易出问题。

brilliant fix

Solution: To Turn off decodeSlash: Thanks to @zqq90 ``` @FeignClient(name = "yourClient", url= "xxxx", configuration = YourClient.ClientConf.class) public interface YourClient { class ClientConf{ @Bean Contract contract(@Autowired(required = false) List parameterProcessors,...

已经有此选项 

`javafx/application/Application` 找不到，可能是你cmd里面的JAVA和IDEA里面使用的JDK不一样。
