Answer 1

你试试在response.setCharacterEncoding( "UTF-8 "); 前面加上
response.setContentType("text/html;charset=UTF-8")看行不呢

Answer 2

确定前台页面也是UTF-8格式？

Answer 3

木有页面 就是直接输入的~！页面代码
?????
[{"foodpic":"img/demo.jpg","foodId":"3","foodcart":"tb1","foodnumber":1,"foodenergy":34,"foodName":"??"}]

Answer 4

顺序错了。 试试看调整这样的。request.setCharacterEncoding( "UTF-8 "); 
response.setCharacterEncoding( "UTF-8 "); PrintWriter   out=response.getWriter(); 
//这句在那两句下面

Answer 5

12楼 正解  谢谢各位大能了 因为在用getresponse() 之前先给他定义编码就好了~！
