1.2.28版本FastJsonHttpMessageConverter反序列化问题
Author: mttyddCreated May 3, 2017Updated Oct 6, 2024
1.自定义一个类继承hashmap，并在构造函数里设置一个值 2.序列化的时候用：SerializerFeature.WriteClassName 3.发送给服务端，服务端最终会执行DefaultJSONParser里365行代码，无法反序列化出正确的对象
测试代码如下：
public static class MyMap extends HashMap<String, Integer> {
private static final long serialVersionUID = -3933206767511509280L;
public MyMap() {
this.put("uuid", 1);
}
}
@Test
public void test1() {
MyMap map = new MyMap();
map.put("key1", 111);
map.put("key2", 222);
String text = JSON.toJSONString(map, SerializerFeature.WriteClassName);
MyMap map2 = JSON.parseObject(text, MyMap.class);
assertTrue(111 == map2.get("key1")); // error
