spring boot - 迫使我在运行时使用jersey client 1.19

Question

我这里有一个棘手的情况。我正在使用

• spring starter parent 2.0.0.RELEASE
• spring cloud version Finchley.BUILD-SNAPSHOT

后者将在运行时提供jersey-client 1.19.1。但是，我必须使用的另一个公司内部库依赖于2.23.2的版本org.glassfish.jersey.client.ClientRequest。特别是accept方法

    /**
     * Add new accepted types to the message headers.
     *
     * @param types accepted types to be added.
     */
    public void accept(final String... types) {
        getHeaders().addAll(HttpHeaders.ACCEPT, (Object[]) types);
    }

使用版本javax.ws.rs.core.MultivaluedMap.addAll中不存在的1.19.1。

我尝试了什么

第一个想法是排除由jersey-client 1.19.1引入的版本spring cloud eureka，而是依赖jersey-client 2.23.2。 这给出了另一个错误：

有了这个pom，我得到了这个新错误：

***************************
APPLICATION FAILED TO START

Description:

Parameter 0 of method cachingLBClientFactory in org.springframework.cloud.openfeign.ribbon.FeignRibbonClientAutoConfiguration required a bean of type 'org.springframework.cloud.netflix.ribbon.SpringClientFactory' that could not be found.

感谢您的帮助！

Answer 1

它不是春季启动，而是spring-cloud-netflix。特别是Eureka客户端是用它构建的，这是一个问题。

请参阅文档的此部分：http://cloud.spring.io/spring-cloud-static/spring-cloud-netflix/1.4.3.RELEASE/single/spring-cloud-netflix.html#_eurekaclient_without_jersey

我们已经建立了RestTemplate eureka客户端。要使用它，请在pom.xml中执行以下操作
