[290044632]

【环境版本】

• JDK：jdk-21.0.2
• fastjson：2.0.53

        public Transform(String from, String to) {
            this(new Bridge(from, to));
        }

        public Transform(Bridge bridge) {
            this.bridge = bridge;
        }
    }

    record Bridge(String from, String to) {

    @Test
    public void testJDKRecord() throws Exception {
        String json = JSON.toJSONString(new Transform("zhangsan", "lisi"));
        System.out.println(json);
        Transform transform = JSON.parseObject(json, Transform.class);
        System.out.println(transform);
  }

【期望输出】

{"bridge":{"from":"zhangsan","to":"lisi"}}
Transform[bridge=Bridge[from=zhangsan, to=lisi]]

【实际输出】

{"bridge":{"from":"zhangsan","to":"lisi"}}
