java - org.springframework.web.servlet.DispatcherServlet noHandlerFound(警告: No mapping found for HTTP request)

Question

我在 Tomcat 服务器中遇到此错误:

WARNING: No mapping found for HTTP request with URI [/TestProject/user/register] in DispatcherServlet with name 'ravi'

我在重定向到注册页面时收到上述错误。

我的 web.xml:

<servlet>
    <servlet-name>ravi</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>ravi</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

我的 ravi-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:context="http://www.springframework.org/schema/context"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://www.springframework.org/schema/beans

      http://www.springframework.org/schema/context/spring-context.xsd ">
  <context:component-scan base-package="com.test.webProject" />
  <mvc:annotation-driven />
  <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
    <property name="prefix" value="/WEB-INF/view/" />
    <property name="suffix" value=".jsp" />
  </bean>

我的 Controller 类:

@Controller
@RequestMapping(value="/TestProject/user")
public class UserController {
    @RequestMapping(value="/register", method=RequestMethod.GET)
    public String newEmployeeForm(Model model) {
        model.addAttribute("User Registration" , "User Registration");
        return "register";
    }

如何调试此问题？

Answer 1

您确定 WEB-INF/view 中有 register.jsp 吗？如果是，请确保 Controller 类位于 context:component-scan 包

中
