Question

我正在使用Spring MVC Framework，而我一直使用的IDE是NetBeans。自上周整周以来，我一直面临问题，这使我心烦意乱，现在我正站在世界前列（希望今天晚上我会面带微笑上床睡觉）。这是Snapshot of Project Structure

    <body>
        <form action = "AddNumbersFunction">

            <table>
                <tr>
                    <td> First Number: </td>
                    <td> <input type = "text" name = "num1"> </td>
                </tr>
                <tr>
                    <td> Second Number: </td>
                    <td> <input type = "text" name = "num2"> </td>
                </tr>
                <tr>
                    <td></td>
                    <td> <input type = "submit" name = "SubmitButton" value = "Add Numbers"> </td>
                </tr>

</beans>

AddController.java

package com.MAKaey;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class AddController {

    @RequestMapping("/AddNumbersFunction")
    public void add(){

        System.out.println("I'm Here!");
    }
}

问题是当我运行项目时，出现以下错误（javax.servlet.ServletException）Exception's Snapshot 甚至不显示任何文本字段，因为在您运行项目时，显示的第一页就是该错误。请帮助我！谢谢！

Answer 1

更改

<ctx:annotation-config></ctx:annotation-config> <ctx:component-scan base-package = "com.MAKaey"></ctx:component-scan>

到

<tx:annotation-config></tx:annotation-config>
<tx:component-scan base-package = "com.MAKaey"></tx:component-scan>

因为您是在此处使用xmlns:tx="http://www.springframework.org/schema/tx"进行导入
