FF4J：FeatureStoreHttp抛出NoClassDefFoundError：javax / ws / rs / client / RxInvokerProvider

编程问答 2022-08-12

问题描述

我创建了一个包含所有功能的功能标志微服务（并已连接到oracle db），我希望其他应用程序/微服务通过Rest API与该功能标志应用进行对话，因为我不想他们直接连接到数据库。这是我的配置。

    @Configuration
    @ConditionalOnClass({FF4j.class })
    public class Ff4jConfig extends SpringBootServletInitializer {
    
        @Bean
        public FF4j getFF4j() {
            FF4j ff4j = new FF4j();
            ff4j.setFeatureStore(new FeatureStoreHttp("http://localhost:9190/api/ff4j"));
    
            return ff4j;
        }
    }

当我调用ff4j.check（“ test”）时，出现以下错误。此外，确实存在测试功能（通过调用REST API进行验证-http：// localhost：9190 / api / ff4j / store / features）。

有人可以建议我是否想念东西。

解决方法

使用Jersey客户端与API交互的类account（将在Spring的Feign或WebClient中的ff4j V2中进行升级）

在这里您缺少课程FeatureStoreHttp。我会考虑在类路径中添加javax.ws.rs.client.RxInvokerProvider，版本为jaxrs-api，如所述的here

附带说明：

  • spring-boot-starter应该用于暴露REST-API / WEB-CONSOLE的组件，而不是在客户端微服务上。
  • 定义启动器核心和aop时已在类路径中
