java对象和json字符串互转

1.使用fastjson.jar包

2.将字符串转换成List结果集

List<Test> columns = JSON.parseArray("json字符串",Test.class);

3.将字符串转换成java对象

Test test = JSON.parseObject("json字符串"，Test.class);

4.将对象转换成json字符

String str =  JSON.toJSONString("java对象");

5.拼接json字符串格式

"{"success":"true","info":"+str+"}"

{"success":"true","info":{"names":[],"moduleName":"test"}}
