JSON的这两个方法不知道能不能帮到你

public static <T> T parseObject(InputStream is, //
                                    Charset charset, //
                                    Type type, //
                                    Feature... features) throws IOException {
        ...
    }

public static final int writeJSONString(OutputStream os, // 
                                             Charset charset, // 
                                             Object object, // 
                                             SerializerFeature... features) throws IOException {
        ...
    }
