能提供重现问题的testcase么？

我也遇到了同样的问题。使用的版本为1.2.56 ；

@JSONField(deserializeUsing =TestFastJSONField.class )
	public void setPaperId(String paperId) {
		this.paperId = paperId;
	}

public class TestFastJSONField implements ObjectSerializer,ObjectDeserializer  {

	@Override
	public void write(JSONSerializer serializer, Object object, Object fieldName, Type fieldType, int features)
			throws IOException {
		 
		 String value = (String) object;
	        String text = value + "|---->";
	        serializer.write(text);
	}

	@Override
	public <T> T deserialze(DefaultJSONParser parser, Type type, Object fieldName) {
		String intValue = parser.parseObject(String.class);
		intValue =intValue +  "!____________________>";
	    return (T)intValue;
	}

	@Override
	public int getFastMatchToken() {
		return  JSONToken.LITERAL_INT;
	}

rr = JSON.parseObject(f, RequestResult.class);
		 System.out.println( JSON.toJSONString(rr));

请问是否是在非Spring环境么

时间太长了，不记得了。
