Spring MVC---3.0 简单入门以及相关理解

下面是自己关于Spring MVC简单的入门例子----以及对于Spring MVC使用的相关理解
----------jar 包如下
jstl-1.2.jar
org.springframework.asm-3.0.5.RELEASE.jar
org.springframework.beans-3.0.5.RELEASE.jar
org.springframework.context-3.0.5.RELEASE.jar
org.springframework.core-3.0.5.RELEASE.jar
org.springframework.expression-3.0.5.RELEASE.jar
org.springframework.web.servlet-3.0.5.RELEASE.jar(也即过去的spring mvc jar package)
org.springframework.web-3.0.5.RELEASE.jar
commons-logging.jar

---------------------------------------示例如下----------------------------

----------------工程根目录下的index.jsp----------------------

<body>



<c:redirect url="/clark.do"></c:redirect>
</body>
</html>

------------------处理请求的spring controller 控制处理逻辑类--------------------

package cn.org.spartacus.spring;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
//声明Controller为注解形式
@Controller
public class HelloWorldController {
   /**
   * @RequestMapping("/clark") 中的值clark与请求返回过来的*.do的*值对应---此步骤关键
   * 关于方法名doAction()可以随意命名，与结果无关
   * @return
   */
    @RequestMapping("/clark")
    public ModelAndView doAction() {
       String message = "hello World,Spring 3.0 MVC!";
       System.out.println(message);
       /*
       * 返回ModelAndView对象
       * return---->对应着view显示的视图名称return.jsp
       * 设置"message"----message
       */
        return new ModelAndView("return","message",message);
    }
}

---------------------返回的View 显示 return.jsp--------------------------
package cn.org.spartacus.spring;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
//声明Controller为注解形式
@Controller
public class HelloWorldController {
   /**
   * @RequestMapping("/clark") 中的值clark与请求返回过来的*.do的*值对应---此步骤关键
   * 关于方法名doAction()可以随意命名，与结果无关
   * @return
   */
    @RequestMapping("/clark")
    public ModelAndView doAction() {
       String message = "hello World,Spring 3.0 MVC!";
       System.out.println(message);
       /*
       * 返回ModelAndView对象
       * return---->对应着view显示的视图名称return.jsp
       * 设置"message"----message
       */
        return new ModelAndView("return","message",message);
    }
}

=================需建立相应的jsp对应的目录===================
部署好之后地址栏输入:http://localhost:8080/部署上的工程名/,就会显示相应的输出结果:
hello World,Spring 3.0 MVC!
