Question

Project Folder structure我在Sring mvc应用程序上浏览了本站点上与 404资源未找到错误相关的大部分问题。我尝试了所有的解决方案，结果仍然没有超过两天的解决方案。我是Spring MVC的新手，并从链接中试用了一个示例应用程序 Simple Spring MVC app

我的代码完全如上面的网站所述。但无论我做出什么改变，仍然会收到404错误。

这是我的 web.xml 部分

@Controller  
public class EmployeeController {  

  @RequestMapping(value = "/employee", method = RequestMethod.GET)  
  public ModelAndView employee() {  
    return new ModelAndView("employeeForm", "command", new Employee());  
   }  

  @RequestMapping(value = "/addEmployee", method = RequestMethod.POST)  
  public String addEmployee(@ModelAttribute("SpringWeb")Employee employee, ModelMap model) {  
     model.addAttribute("name", employee.getName());  
     model.addAttribute("age", employee.getAge());  
     model.addAttribute("empId", employee.getEmpId());  
     model.addAttribute("salary", employee.getSalary());  
     return "employeeDetail";  
   }  
}

控制器文件，的 EmployeeController.java

<form:form action="/addEmployee" method="POST">        
<table><tbody>  
<tr>        <td><form:label path="empId">Employee :</form:label></td>      <td><form:input path="empId"></form:input></td>    </tr>  
<tr>      <td><form:label path="name">EmployeeName:/form:label></form:label></td>       <td><form:input path="name"></form:input></td>    </tr>  
<tr>       <td><form:label path="age">Employee Age:</form:label></td>       <td><form:input path="age"></form:input></td>     </tr>  
<tr>      <td><form:label path="salary">Employee Salary:</form:label></td>     <td><form:input path="salary"></form:input></td>    </tr>  
<tr>         <td colspan="2"><input type="submit" value="Submit"/>  </td>       </tr>  
</tbody></table>  
</form:form>

其中Employee是我的POJO类，带有setter和getter方法。

这是我的 employeeForm.jsp

<context:component-scan base-package="com.dineshonjava.emp.controller">  
</context:component-scan>  
  <context:annotation-config/>
   <bean
        class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="viewResolver">  
 <property name="prefix" value="/WEB-INF/views/"></property>  
 <property name="suffix" value=".jsp"></property>

这是我的 sdnext-servlet.xml

你犯了一个根本性的错误。假设您的项目名称是bunbub-proj，因此要访问的网址是localhost:8080/bunbub-proj。当您发布到/addEmployee时，实际上是在点击localhost:8080/addEmployee而不是localhost:8080/bunbub-proj/addEmployee

修复方法是简单地将.附加到您的所有links/urls。例如。 <form:form action="./addEmployee" method="POST">

注意：浏览器将localhost：8080视为基本URL或主机网址。
