我已经使用Spring 3.1和Spring-Jersey 1.x，Jackson 2.x和Hibernate一段时间了。我想升级到Spring-Jersey 2.6。
根据Jersey用户指南和示例应用，我包含所有相关的依赖项。我有一种感觉，我的问题可能与我使用Jackson和JAXB注释的POJO有关，但我似乎无法弄清楚如何前进。杰克逊以前解析JAX-B注释似乎没有任何问题，所以我不确定如何修改我的配置。
我的应用程序看起来像：
public class MyApplication extends ResourceConfig {
public MyApplication(){
packages(true,"com.my.app");
register(JacksonContextResolver.class); //Custom Context Resolver
register(JacksonFeature.class);
}
}
启动时我收到此错误：

答案 0 :(得分：14)
当我从Spring-Jersey 1.x升级到2.x时，我遇到了完全相同的问题。
我发现我还在使用jersey-core-1.18.1 jar。
删除它修复了这个问题！
