springcloud启动eureka报错java.lang.ClassNotFoundException: com.sun.jersey.api.core.DefaultResourceConfig

最近开始学习spring cloud,因为钱不久使用过spring boot，所以轻松上手。

然后弄清楚我们的消费者 服务者 服务发现者，然后就跟着教程走起来，然后就悲剧的出现如下的一幕

换了四五个版本的 cloud.version 同样出现问题：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [cloud.eureka.server.EurekaServer]; nested exception is java.lang.IllegalStateException: Failed to introspect annotated methods on class org.springframework.cloud.netflix.eureka.server.EurekaServerConfiguration

理论上我还是认为maven搞的好好的，不会出现这样的错误，但是最终还是没办法，找不到类就是找不到类

就直接上网找这个：com.sun.jersey.api.core.DefaultResourceConfig

然后塞进maven里面，也可以先下载jar放进去试试

远程地址如下：

http://grepcode.com/snapshot/repo1.maven.org/maven2/com.sun.jersey/jersey-bundle/1.19/

我使用的jersey 1.19.1 所以我找的1.19 然后就ok 了，大家自己看下自己的jersey版本，自动添加

下面是maven代码：

        com.sun.jersey
        jersey-bundle
          1.19
     

搞定，启动妥妥的，eureka成功启动.

这是今天新加的，使用spring cloud并用maven打包独立运行时出现异常，始终无法处理，没办法最终又回到了
java.lang.ClassNotFoundException: com.sun.jersey.api.core.DefaultResourceConfig
这一次到墙外面逛了一圈，还是老外经验足：
url: https://github.com/spring-projects/spring-boot/issues/1345
pom.xml 添加如下代码
                
   org.springframework.boot
   spring-boot-maven-plugin
   
       
               
                       com.sun.jersey
                       jersey-server
               
               
                       com.sun.jersey
                       jersey-core
               
               
                       com.sun.jersey
                       jersey-servlet
               
       
   

报错的原因是因为jar出现了冲突：导出的jar也能正常运行，算是把这个坑填好了
