测试代码

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);

最初发现项目中使用的是fastjson-1.2.7.jar

报错如下：

最早发现这个问题是在springmvc实体属性注入的时候，经过修改各种springmvc配置无效。

后来联想到最近使用的mybatis使用LocalDateTime/LocalDate等类使用了jsr310的时间类，需要额外添加jar包支持。

最初错误的把jackson-datatype-jsr310-2.7.0-rc1.jar添加进来，调试一直无效。

后来发现一篇文章Fastjson支持Java8中的LocalDateTime吗？，说fastjson-1.2.11支持，开始更换版本。

笔者从mvnrepository.com下载相应的版本，经过最终测试，wenshao的说法是错误的。

必须使用fastjson-1.2.12版本以上才能正常解析。
