简介
基本风格是按照spring mvc做的,在后期会加入一些新的特性,封装成易于自己项目使用的mvc框架。

功能简介:
1. 支持将客户端参数封装成对象,类型自动转换
2. 支持注解,配置controller和方法@RequestMapping
3. 方法中可以对request和response进行访问
4. 支持jstl
5. 可配置编码
6. controller方法的参数可以任意调换
7. 404报错提醒
8. restfull支持@PathVariable
快速使用入门
jar包:
在dist目录中copy easymvc.jar和依赖jar包到web项目中
在web项目中,resources目录下建立mvc-servlet.xml
<beans>
<!-- 编码 -->
<constant name="charsetEncoding">utf-8</constant> <!-- 扫描的目录 -->
<scan base-package="com.easymvc.controller"/> </beans>
web.xml中配置:
<servlet>
<servlet-name>EasymvcInitServlet</servlet-name>
<display-name>EasymvcInitServlet</display-name>
<load-on-startup>1</load-on-startup>
<description></description>
<servlet-class>com.easymvc.servlet.EasymvcInitServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>EasymvcInitServlet</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
Controller:
@Controller //Controller注解
public class TestController { @RequestMapping(value = "/test.html")
public String test(Model model,User user,HttpServletRequest request,HttpServletResponse response){
System.out.println("controller:"+user.getName());
List<User> list = new ArrayList<User>();
for(int i=0;i<2;i++){
User user1 = new User();
user1.setName("哈哈"+i);
list.add(user1);
}
model.addAttribute("list", list);
System.out.println(request);
System.out.println(response);
return "test";
}
}
jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <html>
<head>
<style type="text/css">
div{
padding:5px;
} </style>
</head> <body>
<div style="color: green"> <form action="test.html" method="POST">
<div>
name: <input name="name" type="text"/>
</div>
<div>
orderInfo.orderId: <input name="orderInfo.orderId" type="text"/>
</div>
<div>
orderInfo.user.name:<input name="orderInfo.user.name" type="text"/>
</div>
<div>
sex: <input name="sex" type="text"/>
</div>
<div>
birthDate: <input name="birthDate" type="text"/>
</div>
<div>
type: <input name="type" type="text"/>
</div>
<div>
amt: <input name="amt" type="text"/>
</div>
<div>
status: <input name="status" type="text"/>
</div>
<input type="submit">
</form> </div>
</body> </html>
restfull支持:
@RequestMapping(value = "/test/{userId}/test3.html")
public String test3(@PathVariable("userId") String userId){
System.out.println("======================="+userId);
return "test";
}
