java - 从 Spring-Jersey 1.x 迁移到 2.x

Question

一段时间以来，我一直在使用 Spring 3.1 和 Spring-Jersey 1.x、Jackson 2.x 和 Hibernate。我想升级到 Spring-Jersey 2.6。

我根据 Jersey 用户指南和示例应用程序包含所有相关依赖项。我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继续前进。我之前似乎对 Jackson 解析 JAX-B 注释没有任何问题，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);
        }
    }

在启动时出现此错误:

Answer 1

当我从 Spring-Jersey 1.x 升级到 2.x 时，我遇到了完全相同的问题。

我发现我仍然包含 jersey-core-1.18.1 jar。

删除它解决了这个问题!
