I have a Java app working with CouchDB. For parsing JSON from it, I use lib: com.google.code.svenson v.1.3.8 But, I've got a problem. I receive JSON, and one property in it I want to exclude. Example:

{"groups":[], "norms":[], "unit":null, "_attachments":{
    "revision/1-b7c9e44edecb4c6509ce75d84d3aa06d":{
        "content_type":"application/json",
        "revpos":2,
        "digest":"md5-qPtWsDPF7vQANTQvQzmjrA==",
        "length":684,
        "stub":true
    }
}}

I need to exclude "_attachments" field and all inners. But problem is, that property revision is dynamically. It changes all time. And my code doesn't work: 

public class TestDTO {

    private String attachment;
    private String revision;
    private String contentType;
    private String revpos;
    private String digest;
    private String length;
    private String stub;

    @JSONProperty(ignore = true, value = "_attachments")
    public void setAttachment(String attachment) {
        this.attachment = attachment;
    }

    public String getRevision() {
        return revision;
    }

    @JSONProperty(ignore = true, value = "revision/")
    public void setRevision(String revision) {
        this.revision = revision;
    }
//other get/set methods 
}

Yes, you can do it. All you need is to declare the List of Address as transient property in you business object.

Then add the following code to your jsonConfig:

JsonConfig jsonConfig = new JsonConfig();
jsonConfig.setIgnoreTransientFields(true);
