[英]How to retrieve a record using Spring JDBC
我正在嘗試搜索記錄,並使用Spring JDBC在JSP中顯示它。 我現在在瀏覽器上遇到以下錯誤。
異常消息: 頁面
我的JSP:Search.jsp:
<div class="container"> <div class="col-xs-12 col-sm-8 col-md-6 col-sm-offset-2 col-md-offset-3"> <div class="row"> <div class="col-xs-12 col-sm-6 col-md-6"> <div class="form-group"> <form action="/SpringMail/searchresults" method="get"> <input type="text" name="searchRecord" id="search_record" class="form-control input-lg" placeholder="Enter email to search" tabindex="1" required="required"> <div class="col-xs-12 col-md-6"><input type="submit" value="Search" class="btn btn-primary btn-block btn-lg search" tabindex="4"></div> </form> </div> </div> </div> </div> </div>
Searchresult.jsp:它有一個表。 因此,我只包含其中的代碼。
<table class="table"> <thead> <tr> <th>#</th> <th>Firstname</th> <th>Lastname</th> <th>DisplayName</th> <th>DateOfBirth</th> <th>Email</th> <th>Password</th> <th>Contact</th> <th>Skills</th> </tr> </thead> <tbody> <% List students = (List)request.getAttribute("searchresult"); Iterator stdIter = students.iterator(); while(stdIter.hasNext()) { Student s = (Student) stdIter.next(); %> <tr> <td><% s.getFirstName(); %></td> <td><% s.getLastName(); %></td> <td><% s.getDisplayName(); %></td> <td><% s.getDateOfBirth(); %></td> <td><% s.getEmail(); %></td> <td><% s.getPassword(); %></td> <td><% s.getContact(); %></td> <td><% s.getStudentSkills(); %></td> </tr> <% } %> </tbody> </table>
我的控制器:RegistrationController:
` // For Search
@RequestMapping(value="/search", method=RequestMethod.GET)
public ModelAndView getSearchForm() {
ModelAndView searchmv = new ModelAndView("search");
return searchmv;
}
@RequestMapping(value="/searchresults/{email}", method=RequestMethod.GET)
public ModelAndView searchResults(@PathVariable("email") String email,HttpServletRequest request) {
System.out.println("Inside Search method");
ModelAndView searchResult = new ModelAndView("searchresult");
request.setAttribute("searchresult", st.getStudent(email));
return searchResult;
}
// For Search`
getStudent():
public List<Student> getStudent(String email) {
System.out.println("Inside getStudent() method");
System.out.println("Entered email: " + email);
List studentList = new ArrayList();
String sql = "select * from student where email = " + email;
studentList = jt.query(sql, new StudentRowMapper());
return studentList;
}
我是第一次這樣做。 請指導我正確的方法。
我得到了答案。 方法:RegistrationController中的searchResults格式錯誤。 我這樣修復。
@RequestMapping(value="/searchresults", method=RequestMethod.GET)
public ModelAndView searchResults(@RequestParam("searchRecord") String email, Map model) {
ModelAndView searchResult = new ModelAndView("searchresult");
model.put("searchresult", st.getStudent(email));
return searchResult;
}
感謝您的投入
