json数据转成lists数据

Question

{"id":-1,"name":"Gantt editor","progress":0,"description":"","code":1,"level":0,"status":"STATUS_ACTIVE","depends":"","canWrite":true,"start":1524758400000,"duration":22,"end":1526745599999,"startIsMilestone":true,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":true}
怎么转成list格式数据 存入数据库。自己写了一部分，不知道能否用上package vo;public class Gantt { private int id_a;

Answer 1

直接用fastjson就可以转啊，为啥这么复杂

Answer 2

实际返回的字符串是
{"tasks":[{"id":-1,"name":"Gantt editor","progress":0,"description":"","code":1,"level":0,"status":"STATUS_ACTIVE","depends":"","canWrite":true,"start":1524758400000,"duration":22,"end":1526745599999,"startIsMilestone":true,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":true},{"id":-2,"name":"coding","progress":0,"description":"","code":"1.1","level":1,"status":"STATUS_ACTIVE","depends":"","canWrite":true,"start":1524758400000,"duration":10,"end":1525708799999,"startIsMilestone":false,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":true},{"id":-3,"name":"gantt  part","progress":0,"description":"","code":"1.1.1","level":2,"status":"STATUS_ACTIVE","depends":"","canWrite":true,"start":1524758400000,"duration":2,"end":1524931199999,"startIsMilestone":false,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":false},{"id":-4,"name":"editor  part","progress":0,"description":"","code":"1.1.2","level":2,"status":"STATUS_SUSPENDED","depends":"3","canWrite":true,"start":1524931200000,"duration":4,"end":1525363199999,"startIsMilestone":false,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":false},{"id":-5,"name":"testing","progress":0,"description":"","code":"1.2","level":1,"status":"STATUS_SUSPENDED","depends":"2:5","canWrite":true,"start":1526140800000,"duration":7,"end":1526745599999,"startIsMilestone":false,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":true},{"id":-6,"name":"test on safari","progress":0,"description":"","code":"1.2.1","level":2,"status":"STATUS_SUSPENDED","depends":"","canWrite":true,"start":1526140800000,"duration":2,"end":1526313599999,"startIsMilestone":false,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":false},{"id":-7,"name":"test on ie","progress":0,"description":"","code":"1.2.2","level":2,"status":"STATUS_SUSPENDED","depends":"6","canWrite":true,"start":1526313600000,"duration":3,"end":1526572799999,"startIsMilestone":false,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":false},{"id":-8,"name":"test on chrome","progress":0,"description":"","code":"1.2.3","level":2,"status":"STATUS_SUSPENDED","depends":"6","canWrite":true,"start":1526313600000,"duration":2,"end":1526486399999,"startIsMilestone":false,"endIsMilestone":false,"collapsed":false,"assigs":[],"hasChild":false}],"selectedRow":0,"deletedTaskIds":[],"canWrite":true,"canWriteOnParent":true}能给具体的语句吗？本人小白

Answer 3

fastjson支持string转实体类（或者实体类列表）。
然后你把实体类数据保存到数据库不就行了。

Answer 4

直接用jackson包自带的api呀，都可以互相转换的。

Answer 5

引入org.JSON 或者alibaba的JSON 就可以不用麻烦自己写那么多东西了 
项目构建工具引入dependency 或者自己手动下载

Answer 6

阿里巴巴的fasejson，了解一下
