spring mvc ajax编码

Question

编码问题。 Spring MVC控制器从ajax char'？'收到而不是“A”等等......所有网页上的编码是UTF-8，在JavaScript文件显示正确的字符警惕，设立Ajax和添加过滤器不工作

*javascript* 

$.ajax({ 
    url : urlID,   
    contentType: "text/html; charset=utf-8", 
    data : parameters, 
    success : function(data, textStatus) { 
     $(contentID).empty().html(data); 
    }, 
    error : function(jqXHR, textStatus, errorThrown) { 
     $("#errorMessage").empty().html(
       "<h3>Exception: " + errorThrown + "</h3>"); 
    } 
}); 

控制器

@RequestMapping(value = "/marketing-changepage", method = RequestMethod.GET) 
    public String marketingChangepage(HttpServletResponse response, @RequestParam String startDate, 
      @RequestParam String endDate, @RequestParam String device, 
      @RequestParam String source, Model model, Principal principal) {   
     AjaxRequestParams ajaxRequestParams = new AjaxRequestParams(); 
     ajaxRequestParams.setDateRange(new DateRange(startDate, endDate)); 
     ajaxRequestParams.setSource(source); 
     ajaxRequestParams.setDevice(device.toLowerCase()); 
     ajaxRequestParams.setClientInfo(userService 
       .fetchClientInfoByUserName(principal.getName())); 

     preparePage(ajaxRequestParams, model, principal); 
     return "marketing/content_marketing"; 
    } 

的web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Answer 1

只是配置您的server.xml文件，并添加属性URIEncoding="UTF-8"像下面这样：

<Connector port="8080" maxHttpHeaderSize="8192" 
       maxThreads="150" minSpareThreads="25" maxSpareThreads="75" 
       enableLookups="false" redirectPort="8443" acceptCount="100" 
       connectionTimeout="20000" disableUploadTimeout="true" 
       URIEncoding="UTF-8" 
    /> 

，并请参阅本维基here，约在Tomcat的字符编码。

并且还参考这个答案here。

希望有所帮助。
