有没有一种方法，当我使用jackson＆spring mvc将json映射到pojo时，我不需要为布尔字段添加@JsonProperties

Question

I cannot find a way to fix this issue, but... maybe it's not an issue.

I use Extjs as the front-end and Spring MVC as backend, the Ajax request looks like:

{"isOk": true}

The Mapping DTO is:

public class TestDTO implements Serializable {

    private static final long serialVersionUID = -6074462313103219627L;

    private Boolean isOK;
    public Boolean isOk(){...}
    Public void setOk(Boolean isOk){...}
}

The get/set method be generated by intellij idea, as you can imagine that jackson works fine if I add @JsonProperty("isOk") under the "setOk" method.

But I have a lot of ***DTO objects, so is there a convenient method to reslove this issue? thanks.

I have checked the "com.fasterxml.jackson.databind.SerializationFeature" class, and didn't find any config which like the "compatible_boolean_and_ignore_is_keyword" etc..

I didn't test it, but might be helpful for your case:

Basically, try to rename your getter/setter to:

getIsOk / setIsOk

It should then serialize/deserialize json in form of {"isOk": ... }

It's been some time since I used spring, but if I recall correctly you have to

• annotate the class with @Entity
• implement the Serializable interface ( class DTO implements Serializable )
• provide a default constructor
