測試代碼spring
String json = "[{\"f_clsm\":\"111\",\"f_fk\":\"-1\",\"f_clkssj\":\"2019-05-24 13:52:11\",\"f_cljssj\":\"2019-05-24 14:52:11\",\"f_clryid\":\"1000645\"}]"; List<UserIssueProcessDto> list = JSON.parseObject(json, new TypeReference<List<UserIssueProcessDto>>() {}); System.out.println(list);
最初發現項目中使用的是fastjson-1.2.7.jarjson
報錯以下：mybatis

最先發現這個問題是在springmvc實體屬性注入的時候，通過修改各類springmvc配置無效。this
後來聯想到最近使用的mybatis使用LocalDateTime/LocalDate等類使用了jsr310的時間類，須要額外添加jar包支持。lua
最初錯誤的把jackson-datatype-jsr310-2.7.0-rc1.jar添加進來，調試一直無效。spa
後來發現一篇文章Fastjson支持Java8中的LocalDateTime嗎？，說fastjson-1.2.11支持，開始更換版本。.net
筆者從mvnrepository.com下載相應的版本，通過最終測試，wenshao的說法是錯誤的。
必須使用fastjson-1.2.12版本以上才能正常解析。
