第一个SpringMVC

1.编写web.xml 放置于  WebContent/WEB-INF 下

<?xml version ="1.0" encoding ="UTF-8"?>

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance "
    xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd ">
    <!-- 配置前端控制器 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        <!-- 初始化 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!-- 绑定springmvc配置文件 -->
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
    </servlet>

    <!-- 使用前端控制器 -->
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <!-- 配置拦截 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

2.编写springmvc配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
         http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.3.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">
    <!-- 开启spring注解扫描的包 -->
    <context:component-scan base-package="user" />

    <!-- 开启springmvc默认的器-->
    <mvc:annotation-driven></mvc:annotation-driven>

    <!-- 开启mvc的视图转化器 -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver"
        id="internalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/WEB-INF/view/" />
        <!-- 后缀 -->
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

3.建立处理类

package user;

import java.util.Date;

import javax.xml.crypto.Data;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import converter.date_converter;
import javabean.userbean;

@Controller
@RequestMapping("/user")
public class user {
    @RequestMapping(path="/init")
    public String denglu(userbean user,Data data) {
        System.out.println("成功了"+user);
        System.out.println(data);
        return "init";
    }
    
}
