在使用Jackson ObjectMapper时如何忽略pojo注释? [英] How to ignore pojo annotations while using Jackson ObjectMapper?

问题描述

我有一个带有Jackson批注的POJO

I've a POJO with Jackson annotations

     public class Sample{

        private String property1;

        @JsonIgnore
        private String property2;

        //...setters getters

     }

因此，当其他框架(例如RestEasy)将Jackson库用于自动编组时，这些注释将帮助指导序列化和反序列化过程.

So, when Jackson library is used for automarshalling by other frameworks such as RestEasy these annotations help guide the serialization and deserilization process.

但是，当我想使用ObjectMapper mapper = new ObjectMapper()显式进行序列化时，我不希望这些注释产生任何效果，而是根据自己的需求配置mapper对象.

But when I want to explicitly serialize using ObjectMapper mapper = new ObjectMapper(), I don't want those annotations to make any effect, instead I will configure the mapper object to my requirement.

那么，如何在使用ObjectMapper时使注释不起作用?

So, how to make the annotations not make any effect while using ObjectMapper?

推荐答案

配置您的ObjectMapper不要使用这些注释，如下所示:

Configure your ObjectMapper not to use those Annotations, like this:

ObjectMapper objectMapper = new ObjectMapper().configure(
                 org.codehaus.jackson.map.DeserializationConfig.Feature.USE_ANNOTATIONS, false)
                    .configure(org.codehaus.jackson.map.SerializationConfig.Feature.USE_ANNOTATIONS, false);

这行得通！
