rickiehsu opened a new issue, #12591:
URL: https://github.com/apache/dubbo/issues/12591
### Environment
* Dubbo version: 3.2.2
* Operating System version: win 10
* Java version: 1.8
* Fastjson2: both 2.0.31,2.0.34
### Steps to reproduce this issue
This code reproduce the problem
```
public void testWriteReadString() throws Exception {
QueryVo model = new QueryVo();
model.addOrderClause(new OrderClause("task_no", false));
FrameworkModel frameworkModel = new FrameworkModel();
Serialization serialization =
frameworkModel.getExtensionLoader(Serialization.class).getExtension("fastjson2");
URL url = URL.valueOf("").setScopeModel(frameworkModel);
// write pojo, read failed
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
ObjectOutput objectOutput = serialization.serialize(url,
outputStream);
objectOutput.writeObject(model);
objectOutput.flushBuffer();
byte[] bytes = outputStream.toByteArray();
ByteArrayInputStream inputStream = new ByteArrayInputStream(bytes);
ObjectInput objectInput = serialization.deserialize(url,
inputStream);
Object obj = objectInput.readObject();
Assertions.assertEquals(obj, objectInput.readObject());
frameworkModel.destroy();
}
**QueryVo.java**
public class QueryVo implements Serializable {
private int limit;
private int offset;
private Map<String, Object> queryObj;
private List<OrderClause> orderClauses;
public int getLimit() {
return limit;
}
public void setLimit(int limit) {
this.limit = limit;
}
public int getOffset() {
return offset;
}
public void setOffset(int offset) {
this.offset = offset;
}
public Map<String, Object> getQueryObj() {

}
public void setQueryObj(Map<String, Object> queryObj) {

}
public List<OrderClause> getOrderClauses() {

}
public void addOrderClause(OrderClause orderClause) {
if (this.orderClauses == null) {
this.orderClauses = new ArrayList<>();
}
this.orderClauses.add(orderClause);
}
}
**OrderClause.java**
public class OrderClause implements Serializable {
private String fieldName;
private boolean ascending = true;
public OrderClause(){
}
public OrderClause(String fieldName){

}
public OrderClause(String fieldName, boolean ascending){
this.fieldName = fieldName;

}

return fieldName;
}
public void setFieldName(String fieldName) {
