问题描述

简要描述您碰到的问题。
json类型和实体类型不一致时,parse报错

环境信息

请填写以下信息:

  • OS信息: [e.g.:CentOS 8.4.2105 4Core 3.10GHz 16 GB]
  • JDK信息: Openjdk 1.8.0_312
  • 版本信息:Fastjson2 2.0.15

重现步骤

如何操作可以重现该问题:
1.新建实体类A
2.定义字符串json("{"content": "aaa", "type": ""}")
使用JSON.parseObject(json, A.class)报错

  1. 使用 xxx.xxx 方法
  2. 输入 ... 数据
  3. 出现 ... 错误
//可在此输入示例代码
public class TestJson {

@Data
public static class A {
    private Integer type;
    private String content;
}

public static void main(String[] args) {
    String json2 = "{\n" +
            "  \"content\": \"123456\",\n" +
            "  \"type\": \"\"\n" +
            "}";
    A a = JSON.parseObject(json2, A.class);
    System.out.println(a);
}
}

期待的正确结果

对您期望发生的结果进行清晰简洁的描述。
TestJson.A(type=null, content=123456)

附加信息

如果你还有其他需要提供的信息,可以在这里填写(可以提供截图、视频等)。
若更换json中两个字段的位置,则可正常解析,如下
String json2 = "{\n" +
" "type": "",\n" +
" "content": "123456"\n" +
"}";
