我试图从Moxy转移到杰克逊json媒体提供商为我的泽西岛网络服务,并发现了迄今为止我无法解决的几个问题：
首先,moxy对于同一段代码工作正常,但因为我们在其他项目中使用jackson,我希望保持一致…
所以我改变了
1)对pom的依赖
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>${jersey.version}</version>
</dependency>
2)ResourceConfig regester
register(JacksonFeature.class)
但是当我运行我的webservice时,我开始得到这个异常(基本上当我从Web服务方法返回时会发生这种情况)：

是的……显然我们使用WildFly作为应用程序服务器,如果它很重要.
因此,如果有人能够指出我可能存在的问题,那就太棒了.
干杯!
解决方法
问题似乎发生在FilteringJacksonJaxbJsonProvider,这是泽西岛自己的杰克逊提供商,因为它支持它
Entity Data Filtering.似乎有一些注入(调用Weld)继续导致它失败.如果你不需要实体数据过滤功能,你可以摆脱jersey-media-json-jackson而不是使用
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>${jackson2.version}</version>
</dependency>
// as of now ${jackson2.version} == 2.5.3
至于Weld问题,我不确定它是否会在将来给你造成问题,所以我不会考虑改变Jackson依赖是一个解决方案,而不是解决方法.
你在评论中说你正在使用gf-cdi.也许这就是问题所在.在泽西岛2.14(你使用的是泽西岛2.17)之后不再生成这个神器. CDI支持模块已更改.你可以看到27.3.1. Release 2.15 Highlights.它提到了一些关于CDI支持依赖的东西.
CDI support improvement caused breaking changes for those users directly referring to the following CDI supporting Jersey module in maven:
06001
The above dependency needs to be replaced with:
06002
The following needs to be included in addition if you want to leverage CDI JTA support:
06003
