我试图使用下面的pom创建一个Spring云Eureka服务器，主要来自https://github.com/joshlong/service-registration-and-discovery

但是，我得到＆＃34;错误创建名称为＆＃39; viewControllerHandlerMapping＆＃39;＆＃34;＆＃34;错误，由＆＃34; java.lang.IllegalStateException引起：如果资源当前未启动，则可能无法访问这些资源＆＃34;。

我认为可能与各种Jersey组件的版本有关，分别为1.11和1.13，虽然我没有看到任何一个罐被拉两次。除此之外，我不知道为什么。有任何想法吗？提前谢谢！

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

所以问题是spring-cloud-starter-eureka-server 1.0.3.RELEASE正在拉动相互冲突的球衣版本--1.11和1.13。如果我排除1.13依赖项并将它们重新添加为1.11依赖项，则它可以工作：

有冲突的球衣版本：

[INFO] |  +- org.springframework.cloud:spring-cloud-netflix-eureka-server:jar:1.0.3.RELEASE:compile
[INFO] |  |  +- com.netflix.eureka:eureka-client:jar:1.1.147:compile
[INFO] |  |  |  +- com.sun.jersey:jersey-core:jar:1.11:compile
[INFO] |  |  |  +- com.sun.jersey:jersey-client:jar:1.11:runtime
[INFO] |  |  |  +- com.sun.jersey.contribs:jersey-apache-client4:jar:1.11:runtime
[INFO] |  |  +- com.sun.jersey:jersey-servlet:jar:1.13:compile
[INFO] |  |  +- com.sun.jersey:jersey-server:jar:1.13:compile

修正：
