//注意:需要导入fastjson-1.1.22.jar包
// 1)json数据必须正规 2)java实体类需要有无参构造方法 和set方法 3)实体类不能是内部类 4).自定义的属性与对象名一致才能被解析
// json-->javaBean parseObjectFastJson解析json数据 System.out.println(JSON.parseObject(json, Student.class)); String json2 = "[{name:'张三',age:18},{name:'李四',age:29}]";
// json-->集合 parseArray();
List<Student> list = JSON.parseArray(json2, Student.class);
System.out.println(list); } }
