spring - Spring MVC 中的简单搜索

Question

我是 Spring MVC 的新手，我正在尝试进行简单的搜索。这是我的 Controller 和 View 。如何使搜索真正发挥作用？ findTeamByName 已从接口(interface)实现，并且团队已填充到内存中。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 columns end">
         <button id="button-id" type="submit">Search Teams</button>
       </div>

   </div>

 <div class="row">
      <div>
         ${searchTerm}
     </div>
</div>

Answer 1

您可以返回您的值，即在 ModelAndView

@RequestMapping(value="/search/{searchTerm}")
public ModelAndView Search(@PathVariable("searchTerm") String pSearchTerm) {
    ModelAndView mav = new ModelAndView("search");

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

    return mav;
}

可以通过 ${searchTerm} 在您的 search.jsp 中访问该字段

编辑:

如果你想要像这样搜索:search?searchTerm=java那么你可以这样做:

@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;
}
