ControllerClassNameHandlerMapping類是基於約定的處理程序映射類，它將URL請求映射到配置中提到的控制器的名稱。這個類接受控制器名稱並將其轉換為帶有前導“/”的小寫形式。 例如HelloController映射到URL: “/hello*”。

創建springMVC工程：

ControllerNameHandlerMapping-servlet.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<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" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
   http://www.springframework.org/schema/beans     
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context-3.0.xsd
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"
 
>

    <context:component-scan base-package="com.bwy" />

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

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

    <bean class="com.bwy.controller.HelloController" />
    <bean class="com.bwy.controller.WelcomeController" />

</beans>

根據如上配置，對於/hello*.*的URL，DispatcherServlet會將請求轉發到HelloController類；對於/welcome*.*的URL，DispatcherServlet會將請求轉發到WelcomeController類。

HelloController.java

package com.bwy.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class HelloController extends AbstractController {

  @Override
  protected ModelAndView handleRequestInternal(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
    ModelAndView model = new ModelAndView("hello");
    model.addObject("message", "Hello World!");
    return model;
  }

}

WelcomeController.java

package com.bwy.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class WelcomeController extends AbstractController {

  @Override
  protected ModelAndView handleRequestInternal(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
    ModelAndView model = new ModelAndView("welcome");
    model.addObject("message", "welcome!");
    return model;
  }

}

運行tomcat，並訪問http://localhost:8080/ControllerNameHandlerMapping/welcome2.d，結果如下所示：
