jackson - Jackson使用，String與對象互轉

准備

    // jackson轉換工具 private static final ObjectMapper objectMapper = new ObjectMapper() .configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);

使用

對象轉json

String str = objectMapper.writeValueAsString(new MessageEntity());

json轉對象

List<String> tidList = objectMapper.readValue(tidListSrt, new TypeReference<List<String>>() {});
