Spring系列【12】简单MVC应用
User.java
1 package com.user; 2 3 public class User { 4 private String username; 5 private String password; 6 public String getUsername() { 7 return username; 8 } 9 public void setUsername(String username) {10 this.username = username;11 }12 public String getPassword() {13 return password;14 }15 public void setPassword(String password) {16 this.password = password;17 }18 }
Validation.java
1 package com.validation; 2 3 import javax.servlet.http.HttpServletRequest; 4 import javax.servlet.http.HttpServletResponse; 5 6 import org.springframework.web.servlet.ModelAndView; 7 import org.springframework.web.servlet.mvc.AbstractController; 8 9 import com.user.User;10 11 public class Validation extends AbstractController {12 private User user;13 14 public User getUser() {15 return user;16 }17 18 public void setUser(User user) {19 this.user = user;20 }21 protected ModelAndView handleRequestInternal(HttpServletRequest request,22 HttpServletResponse response) throws Exception {23 String username=request.getParameter("username");24 String password=request.getParameter("password");25 if(username.equals(user.getUsername())&&password.equals(user.getPassword())){26 return new ModelAndView("yes");27 }else{28 return new ModelAndView("error");29 }30 }31 }
以上为本例要用到的jar包，与前几例相比，多了web 和webmvc两个包。
Spring的配置文件如下:
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd"> <!--定义控制器转发视图类 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix"> <value>/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> <!-- 为User对象属性赋值 --> <bean id="user" class="com.user.User"> <property name="username"> <value>admin</value> </property> <property name="password"> <value>111</value> </property> </bean> <!-- 让bean Validation自动装配User并映射do --> <bean name="/login.do" autowire="byName" class="com.validation.Validation"> <property name="user" ref="user"> </property> </bean></beans>
web.xml配置文件如下:
<?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>zidingyi</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping></web-app>
文件结构如下：
注意文件名与return new ModelAndView("yes");的对应关系。。。
特别留言：与User类成员变量的对应关系
