# 1，创建springmvc demo项目 #

*  a, 配置pom.xml依赖
 *  b, 配置WEB-INF目录下的两个文件： web.xml, dispatcher-servlet.xml
 *  c, 编写 index.jsp 页面和 controller代码

# 2, 在idea中配置tomcat ，测试 #

## a, 发布web项目 ##

# \------------------- springmvc demo代码-------------------- #

## 1，配置pom.xml ##

new module --> java webapplication : 添加maven支持，配置pom.xml如下

<properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <springframework.version>4.3.7.RELEASE</springframework.version>
        </properties>
    
        <dependencies>

## 2， WEB-INF目录下： web.xml，dispatcher-servlet.xml ##

### a， web.xml ###

        </bean>
    </beans>

# 3， index.jsp 和 a.HelloController.java #

index.jsp

<a href="hello"><h1>hello,click this!</h1></a>

a.HelloController.java

package a;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.servlet.ModelAndView;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    @Controller
    public class HelloController {
        @RequestMapping(value = "/hello", method = {RequestMethod.GET})
        public ModelAndView successModel(HttpServletRequest request, HttpServletResponse reponse) {
            ModelAndView mav = new ModelAndView();
            request.setAttribute("message", "你好, hello springmvc !");
            mav.addObject("hello");
            return mav;
        }
    }
