JQuery ajax 返回json時出現(xiàn)中文亂碼該如何解決

$.ajax({ 
 url: '/test/testAction.do?method=test', 
 type: 'POST', 
 dataType: 'json', 
 timeout: 5000, 
 async: false, 
 error: function(){ 
 alert('獲取數(shù)據(jù)失敗！'); 
 }, 
 success: function(json){ 
 jsObject = eval(json); 
 } 
 }); 
 return jsObject;

<span style="font-size: x-small;">$.ajax({ 
 url: '/test/testAction.do?method=test',

 async: false, 
 error: function(){ 
 alert('獲取數(shù)據(jù)失敗！'); 
 }, 
 success: function(json){ 
 jsObject = eval(json); 
 } 
 }); 
 return jsObject;</span> 
action：

JSONArray json = JSONArray.fromObject(SysList);//SysList是一個List 
// 設(shè)置response的ContentType解決中文亂碼 
 response.setContentType("text/html;charset=UTF-8"); 
 response.getWriter().print(json.toString()); 
 return null; 
Java代碼 
<span style="font-size: x-small;">JSONArray json = JSONArray.fromObject(SysList);//SysList是一個List 
// 設(shè)置response的ContentType解決中文亂碼 
 response.setContentType("text/html;charset=UTF-8"); 
 response.getWriter().print(json.toString());
