我是Spring MVC的新手,我正在尝试进行简单的搜索.这是我的控制器和视图.如何使搜索实际工作？findTeamByName已经从一个接口实现,并且团队已经填充在内存中.提前谢谢你们!

@Controller
public class SearchController {

  @Autowired    
  SuperPlayerService sp;

  @RequestMapping(value="/search")
    public ModelAndView Search(@RequestParam(value = "searchTerm", required = false) 
    String pSearchTerm, HttpServletRequest request, HttpServletResponse response) {
        ModelAndView mav = new ModelAndView("search");

       mav.addObject("searchTerm", pSearchTerm);
       mav.addObject("searchResult", sp.findTeamByName(pSearchTerm));      

     return mav;
   }
}

JSP:

<%@ page contentType="text/html" pageEncoding="UTF-8" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib prefix="t" tagdir="/WEB-INF/tags" %>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>


<t:MasterTag>
<jsp:attribute name="pageTitle"><c:out value="Search"/></jsp:attribute>
<jsp:attribute name="currentMenuName"><c:out value="Search"/></jsp:attribute>
<jsp:body>





<div class="row">
     <div class="small-3 columns">
        <input type="text" id="txt" name="searchString">
      </div>

       <div class="small-5 …

我正在使用chart.js并渲染圆环图.我想将初始图表总值设置为零,以便它可以呈现完整的"空"图表.当我使用零实例化图表时,它不会呈现.我无法在开发人员文档中找到它如何处理零.

var kPoints = 000;
var mPoints = 000;
var tPoints = 000;
var cPoints = 000;
var doughnutData = [ {
    value : kPoints,
    color : "#FF8000"
}, {
    value : mPoints,
    color : "#99CC00"
}, {
    value : tPoints,
    color : "#0099CC"
}, {
    value : cPoints,
    color : "#333333"
}, ];
var ctx = $("#profileChart").get(0).getContext("2d");
var myDoughnut = new Chart(ctx).Doughnut(doughnutData);
