java - fastjson 或者 Gson 有没有对某个类自定义 json 的办法。

Question

有一个特殊的类型，不希望按照 bean 方式json 化，能不能用自己的方法替换。

Answer 1

Solved it myself:

    ObjectSerializer recordFilter = new ObjectSerializer() {
        @Override
        public void write(JSONSerializer jsonSerializer, Object o, Object o1, Type type) throws IOException {
            SerializeWriter out = jsonSerializer.getWriter();
            Record record = (Record) o;
            if( record != null){
                out.write(record.toJson());
            }else{
                out.writeNull();
            }
        }
    };

    public LocalConductor() {
        SerializeConfig.getGlobalInstance()
                .put(Record.class, recordFilter);

    }

Interface may change

Use the put method of the SerializeConfig class to modify the parsing of the specified type.

I don’t understand very well, you can post an example. If you don’t use beans, you can use fastjson’s get method to return the result

Answer 3

JSONSerializer
