直接來乾貨 基於spring mvc有一定基礎的
首先web.xml如下 我們都知道spring mvc是基於servlet研發的
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>spring-mvc</display-name>
<!-- 配置servlet請求攔截 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/applicationContext-mvc.xml</param-value><!-- 讀取配置文件 -->
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
applicationContext-mvc.xml配置文件如下：
<?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:tx="http://www.springframework.org/schema/tx"
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-3.2.xsd
http://www.springframework.org/schema/tx

<!-- 自動掃描的包名 我的controller的類都在controllers的包下 -->
<context:component-scan base-package="controllers"/>
<!-- 默認的註解映射的支持，自動註冊DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter -->
<mvc:annotation-driven />
<!-- 視圖解釋類 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"/> <!-- 在全目錄下查找 -->
<property name="suffix" value=".jsp"/> <!-- 在全目錄下查找.jsp文件 -->
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
</bean>
</beans>
testController類如下：
package controllers;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import azj.user;
@Controller
@RequestMapping("/admin")
public class testController {
//login.do請求
@RequestMapping("/login") //獲得頁面傳來的值 頁面屬性爲username 用name屬性接受 也可以通過對象傳值
public String addUser(ModelMap mp,@RequestParam("username") String name*/){
System.out.println("com---------");
//傳值
mp.addAttribute("u",u);
//渲染的頁面
return "/welcome";
}
}
