spring-boot - 无法使用 Eureka 客户端运行服务。它因 "Cannot create Jersey client"错误而中断

转载作者：行者123 更新时间：2023-12-05 09:13:38

由于错误“无法创建 Jersey 客户端”而无法运行 eureka 客户端

我有一项服务“insureconnect”，它依赖于此 spring-auth 服务。如果我在没有 insureconnect 的情况下运行 spring-auth，它就可以工作。我在 insureconnect 中有一些类在 spring-auth 中被引用。 Eureka 服务器在 8761 端口上正常运行。使用 Insureconnect 如果我尝试运行 spring-auth 它会中断

spring-auth服务的pom:

spring-auth 启动类


    package com.eureka.auth;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.autoconfigure.domain.EntityScan;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

    @SpringBootApplication(scanBasePackages ={"com.eureka.auth","com.metamorphosys.insureconnect"})
    //@ComponentScan({"com.eureka.auth","com.metamorphosys"})
    //@EntityScan("com.delivery.domain")
    //@EnableJpaRepositories("com.delivery.repository")
    @EnableEurekaClient
    public class SpringEurekaAuthApp {

        public static void main(String[] args) {
            SpringApplication.run(SpringEurekaAuthApp.class, args);
        }
    }

下面是我得到的错误:

最佳答案

我意识到这是一个很晚的答案，但如果其他人被引导到这里，那么我的解决方案，因为我不需要 Jersey ，只是从 eureka-client 中排除 Jersey 依赖:

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>com.sun.jersey</groupId>
                    <artifactId>jersey-client</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>com.sun.jersey</groupId>
                    <artifactId>jersey-core</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>com.sun.jersey.contribs</groupId>
                    <artifactId>jersey-apache-client4</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
