Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create(); return gson.toJson(resultData);
在使用Gson格式化LocalDateTime時,結果並無按照想象中的格式出現,而是出現了下面這種格式 "date":{"year":2019,"month":11,"day":17},"time":{"hour":22,"minute":0,"second":0,"nano":0}java
百度沒搜到,google了一下 https://www.soinside.com/question/FvzpUvjQeuEXXnHFCCkJWm<br> 先實現一個類git
public class LocalDateAdapter implements JsonSerializer<LocalDateTime> { @Override public JsonElement serialize(LocalDateTime localDateTime, Type type, JsonSerializationContext jsonSerializationContext) { return new JsonPrimitive(localDateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))); } }
而後github
Gson gson = new GsonBuilder() .setPrettyPrinting() .registerTypeAdapter(LocalDateTime.class,new LocalDateAdapter()).create(); return gson.toJson(resultData);
就能夠了 "2019-11-17 22:00:00" 更多文章見我的博客 https://zheyday.github.io/json
