Question

我试图在eclipse中运行一个简单的jsp程序但是当我运行程序时我得到以下错误。我现在正在使用spring并且我已经在正确的路径中正确添加了所有的jar.jsp程序如下

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
   <body>
    <h1>WELCOME TO EMPLOYEE ACCESS SITE.PLEASE ENTER THE FOLLOWING INFORMATION</h1>
    <form:form method="POST" action="/Spring/mvc1/addStudent">
    <table>
     <tr>
       <td><form:label path="name">Name</form:label></td>
       <td><form:input path="name" /></td>
     </tr>

     <tr>
       <td><form:label path="id">id</form:label></td>
       <td><form:input path="id" /></td>
     </tr>
     <tr>
       <td colspan="2">
         <input type="submit" value="Submit"/>
       </td>
     </tr>
    </table>  
 </form:form>
  </body>
</html>

当我运行以上程序时，我得到以下错误

我还没有将jsp页面链接到spring class.I只是想看到前端显示。我不知道问题出在哪里......

Answer 1

Spring Controller应返回您的JSP页面。如果你在JSP中没有spring form标签，它会工作，但你在JSP中的表单有需要name和id路径的标签。他们应该来自豆子。因此，您需要将该bean / POJO与JSP一起传递。在Model对象中添加bean。

代码将是这样的：假设页面网址为：http://localhost:8484/yourappcontext/student

@Controller
public class StudentController {

    @RequestMapping(value="/student", method = RequestMethod.GET)
    public String showAddStudentPage(Model model) {

        // instantiate empty student pojo containing name & id needed by JSP
        Student student = new Student();

        // add student pojo in model being sent with JSP
        model.addSttribute("student", student);

        return "addStudent"; // this would be your JSP name.
    }
}

Spring抛出了加载异常（java.lang.NoSuchMethodError :)
