在google搜索后,发现jackson的性能比gson好,我打算在我的项目中用jackson替换gson,但是在运行测试代码时我得到了不同的结果.

private static final Type PHOTOLINKS_TYPE_GSON = new TypeToken<List<Photo>>() {}.getType();
private static final Type PHOTOCAPTIONS_TYPE_GSON = new TypeToken<List<String>>() {}.getType();
Gson gson = new Gson();
private void testGson(String photoJson, String captionJson) {
    GSON_MON.start();
    List<Photo> photos = gson.fromJson(photoJson, PHOTOLINKS_TYPE_GSON);
    List<String> photoCaptions = gson.fromJson(captionJson, PHOTOCAPTIONS_TYPE_GSON);
    GSON_MON.stop();
}

TypeReference<List<Photo>> PHOTOLINKS_TYPE_JACKSON = new TypeReference<List<Photo>>(){};
TypeReference<List<String>> PHOTOCAPTIONS_TYPE_JACKSON = new TypeReference<List<String>>(){};
ObjectMapper mapper = new ObjectMapper();
private void testJackson(String photoJson, String captionJson) {
    JACKSON_MON.start();
    try {
        List<Photo> photos = mapper.readValue(photoJson, PHOTOLINKS_TYPE_JACKSON);
        List<String> photoCaptions = mapper.readValue(captionJson, PHOTOCAPTIONS_TYPE_JACKSON);
    } …
