以下是本人对spring MVC的学习,如果有不正确的地方,请各位多多指教。
不多啰嗦了,直接来代码示例。
环境: tomcat 7.0, jdk 1.6.0_25, spring 3.2.0
- 首先,我一般会先创建一个tomcat工程,这个是根据个人喜好来做。
<?xml version="1.0" encoding="UTF-8"?> <web-app 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" version="3.0" metadata-complete="true"> <welcome-file-list> <welcome-file>index.htm</welcome-file> </welcome-file-list> </web-app>
- 创建index.htm
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Insert title here</title> </head> <body> <h1>test!!!!</h1> </body> </html>
- 配置tomcat的server.xml
<Context path="/springMVC" docBase="你自己的工程路径" debug="0" reloadable="true"> </Context>
- 测试 打开ie,输入http://localhost:8080/springMVC/ ,出现下面画面,证明请求成功。
- 编辑web.xml,加入servlet
<?xml version="1.0" encoding="UTF-8"?> <web-app 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" version="3.0" metadata-complete="true"> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.htm</welcome-file> </welcome-file-list> </web-app>
- 配置结束后,这里面有个契约,上面的servlet的名字是springMVC,这样会默认在工程的WEB-INF文件夹下面找springMVC-servlet.xml文件,所以我们要创建springMVC-servlet.xml。当然也自己指定的文件,网上有很清晰的说明,这里就不再说了,如果有不清楚地,也可以留言给我。
<?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:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd "> <!-- annotation class's package --> <context:component-scan base-package="app"/> <!-- complete request and annotation mapping --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> <!-- analyze view path --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> </bean> </beans>
- 以上配置基本就结束了。现在我们开始创建action和form,来测试下。
package app.login.action; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import app.login.form.LoginForm; @Controller public class LoginAction { @RequestMapping("/index") public String index() { return "login/login"; } @RequestMapping("/login") public ModelAndView login(LoginForm form) { ModelAndView mav = new ModelAndView(); mav.addObject("form", form); mav.setViewName("login/login_success_test"); return mav; } }
-
package app.login.form; public class LoginForm { private String loginID; private String password; public String getLoginID() { return loginID; } public void setLoginID(String loginID) { this.loginID = loginID; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
- 创建结束后,我们修改index.htm
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta http-equiv="refresh" content="0;url=index.html"> <title>Insert title here</title> </head> </html>
- 创建login.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Insert title here</title> <script type="text/javascript"> function doSubmit() { document.getElementById("form").action = "login.html"; document.getElementById("form").submit(); } </script> </head> <body> <form id="form" method="post"> loginID:<input type="text" name="loginID" id="loginID" size="10"><BR> password:<input type="password" name="password" id="password" size="10"><BR> <input type="button" value="login" onclick="doSubmit();"> </form> </body> </html>
- 创建login_success_test.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Insert title here</title> </head> <body> <form> <h1>Hello, ${form.loginID}, welcome to spring MVC.</h1> </form> </body> </html>
- 测试 打开ie,再次输入http://localhost:8080/springMVC/
- 输入测试内容
- 跳转到欢迎画面,这样一个简单的demo就完成了
