spring mvc初級配置樣本__spring

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><!-- 讀取設定檔 -->
    </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設定檔如下：

<?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   
    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.2.xsd  
    http://www.springframework.org/schema/mvc  
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">  
  
    <!-- 自動掃描的包名 我的controller的類都在controllers的包下 -->  
    <context:component-scan base-package="controllers"/>  
  
    <!-- 預設的註解映射的支援，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="/"/>  <!-- 在全目錄下尋找 -->  
        <property name="suffix" value=".jsp"/>  <!-- 在全目錄下尋找.jsp檔案 -->  
        <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  頁面屬性為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";

}


}
