JSONField_jsonDirect_cn

wenshao edited this page May 21, 2016 · 1 revision

在fastjson-1.2.12版本中,JSONField支持一个新的配置项jsonDirect,它的用途是:当你有一个字段是字符串类型,里面是json格式数据,你希望直接输入,而不是经过转义之后再输出。

Model

import com.alibaba.fastjson.annotation.JSONField;

public static class Model {
    public int id;
    @JSONField(jsonDirect=true)
    public String value;
}

Usage

Model model = new Model();
model.id = 1001;
model.value = "{}";

String json = JSON.toJSONString(model);
Assert.assertEquals("{\"id\":1001,\"value\":{}}", json);
