Spring MVC 404在某些请求上出错

Question

我正在Apache7.xx应用程序上开发Spring MVC，并且没有任何错误地设置了所有内容。

我有一个应用程序将我的dispatcher servlet映射到HomeController，HomeController为视图“home/view”提供服务，该视图也在工作。

<form action="/UserRegisteration/RegisterForm" method="POST">
                <table width="283" border="1">
  <tr>
    <td width="123"><label for="firstname">First Name</label></td>
    <td width="144"><input type="text" name="firstname" id="firstname"></td>
  </tr>
  <tr>
    <td><label for="lastname">Last Name</label></td>
    <td><input type="text" name="lastname" id="lastname"></td>
  </tr>
  <tr>
    <td><label for="email">Email</label></td>
    <td><input type="text" name="email" id="email"></td>
  </tr>
  <tr>
    <td><label for="phonecontact1">Phone Contact 1</label></td>
    <td><input type="text" name="phonecontact1" id="phonecontact1"></td>
  </tr>
  <tr>
    <td><label for="phonecontact2">Phone Contact 2</label></td>
    <td><input type="text" name="phonecontact2" id="phonecontact2"></td>
  </tr>
  <tr>
    <td><label for="address1">Address 1</label></td>
    <td><input type="text" name="address1" id="address1"></td>
  </tr>
  <tr>
    <td><label for="address2">Address 2</label></td>
    <td><input type="text" name="address2" id="address2"></td>
  </tr>
  <tr>
    <td><label for="industry ">Industry </label></td>
    <td><input type="text" name="industry " id="industry "></td>
  </tr>
  <tr>
    <td><label for="password">Enter Desired Password</label></td>
    <td><input type="text" name="password" id="password"></td>
  </tr>
  <tr>
    <td><input type="reset" name="clear " id="clear " value="Clear Fields"></td>
    <td><input type="submit" name="register" id="register" value="Register"></td>
  </tr>
</table>
</form>

(UserRegisterationController.java)
@Controller
@RequestMapping("/UserRegisteration")
public class UserRegisterationController {
    @Autowired
    private RegisterationService registerationService;
    @Autowired
    private UserAccountService userAccountService;
    @Autowired
    private PasswordService passwordService;
    public UserRegisterationController() {
    }
    public UserRegisterationController(RegisterationService registerationService, UserAccountService userAccountService, PasswordService password) {
        this.registerationService = registerationService;
        this.userAccountService = userAccountService;
        this.passwordService = password;
    }
    //if checked on register link , forward to registeration page
    @RequestMapping(value="/RegisterForm", method=RequestMethod.GET)
    public String serveRegisterationView()
    {
       return  "UserAccount/Register";
    }
    @RequestMapping(value="/RegisterForm", method=RequestMethod.POST)
    public String createUserAccountRegisteration()
    {
     //if submited registeration 
    //check for previous registeration 
    //if registered prompt , forward to sign in 
    //else create registeration , and user account , and password , forward to main user page  
       return  "UserAccount/Register";
    }

spring-servlet相关片段（在我的例子中是cmgr-servlet）

    <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>

   <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"     
        p:prefix="/WEB-INF/views/" p:suffix=".jsp" p:viewClass="org.springframework.web.servlet.view.JstlView" />

applicationcontext.xml（相关代码段）

 <!-- Activates various annotations to be detected in bean classes --> 
    <context:annotation-config />
    <!-- Scans the classpath for annotated components that will be auto-registered as Spring beans.   For example @Controller and @Service. Make sure to set the correct base-package--> 
    <context:component-scan base-package="com.cmgr.*" />    
    <!-- Configures the annotation-driven Spring MVC Controller programming model.  Note that, with Spring 3.0, this tag works in Servlet MVC only!  --> 
    <mvc:annotation-driven/>
    <!-- mapping of static resources-->
    <mvc:resources mapping="/resources/**" location="/resources/" />

</beans>

register.jsp表单sumbmit的结果：

我注意到浏览器url缺少我的应用程序上下文（/cmgr）正确的url应该是“http：//localhost:8084/cmgr/userregisteration/registerform”

Answer 1

register.jsp表单的结果sumbmit：浏览器URL：（http：//localhost:8084/userregisteration/registerform）

我注意到浏览器url缺少我的应用程序上下文（/cmgr）正确的url>应该是“http：//localhost:8084/cmgr/userregisteration/registerform”

这是正确的，上下文根“/cmgr”丢失了。把你的观点展示给我们，想必表单动作就是问题所在。

您可以使用Spring url标记，如下所示：

<spring:url value="/UserRegisteration/RegisterForm" var="targetURL"/>

<form action="${targetURL}" [...] >
</form>`
