[gonghuan93cn]

问题描述

使用 SerializeConfig.put(Integer.class, ToStringSerializer.instance)进行序列化，将integer类型转成string类型，未生效；

环境信息

• OS信息： [e.g.：macOS 14.5 M1 PRO 16 GB]

• 版本信息：[e.g.：Fastjson2 2.0.53]

重现步骤

public class App {
    public static class People {
        private Integer age;

        private Long hairNums;

        private String name;

        public People(Integer age, String name, Long hairNums) {
            this.age = age;
            this.name = name;
            this.hairNums = hairNums;
        }

        public Integer getAge() {
            return age;
        }

        public String getName() {
            return name;
        }

        public Long getHairNums() {
            return hairNums;
        }
    }

    public static void main( String[] args )
    {
        SerializeConfig stringSerializeConfig = new SerializeConfig();
        stringSerializeConfig.put(Integer.class, ToStringSerializer.instance);
        stringSerializeConfig.put(Long.class, ToStringSerializer.instance);

        People one = new People(10, "aaa", 10000000L);
        System.out.println(JSON.toJSONString(one, stringSerializeConfig, new SerializerFeature[0]));
    }
}

期待的正确结果

{"age":"10","hairNums":"10000000","name":"aaa"}

相关日志输出

{"age":10,"hairNums":"10000000","name":"aaa"}
