小例子
1.jar信息
2.web.xml文件配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" 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_2_5.xsd"> <!-- name 自己拟定 --> <servlet> <servlet-name>test</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- url-pattern 是对应的*.test的响应进行处理的 --> <servlet-mapping> <servlet-name>test</servlet-name> <url-pattern>*.test</url-pattern> </servlet-mapping> </web-app>
3.编写add_emp.jsp（WEB-INF下）
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>add_emp.jsp</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <form method="post"> name:<input name="name" /> phone:<input name="phone" /> empNo：<input name="empNo" /> hireDate:<input name="hireDate" /> department: <select name="dept"> <c:forEach items="${deptList}" var="dept"> <option value="${dept }">${dept }</option> </c:forEach> </select> <input type="submit" value="add" /> </form> </body> </html>
4.在WEB-INF目录下，配置test-servlet.xml 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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <!-- 简单的映射处理 --> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="add_emp.test">addEmpController</prop> </props> </property> </bean> <bean id="addEmpController" class="com.spring.test.EmpFormController"> <property name="commandClass" value="com.spring.test.Emp" /> <property name="formView" value="add_emp" /> <property name="successView" value="success" /> </bean> <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
5.写bean文件
package com.spring.test; import java.text.SimpleDateFormat; import java.util.Date; public class Emp { // 注入的默认是String类型，如果要注入其他类型，则需要数据绑定 private String name; private String phone; private int empNo; //private Date hireDate; private String dept; public String getDepartment() { return dept; } public void setDepartment(String dept) { this.dept = dept; } /*public Date getHireDate() { return hireDate; } public void setHireDate(Date hireDate) { this.hireDate = hireDate; }*/ public int getEmpNo() { return empNo; } public void setEmpNo(int empNo) { this.empNo = empNo; } public String getName() { return name; } public String getPhone() { return phone; } public void setName(String name) { this.name = name; } public void setPhone(String phone) { this.phone = phone; } public String toString() { return "empNo " + empNo + " name "+name + " phone " + phone +", " ; } }
6.处理java文件。
package com.spring.test; import java.sql.Date; import java.text.SimpleDateFormat; import java.util.HashMap; import java.util.Map; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.propertyeditors.CustomDateEditor; import org.springframework.validation.Errors; import org.springframework.web.bind.ServletRequestDataBinder; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.SimpleFormController; public class EmpFormController extends SimpleFormController { @Override protected ModelAndView onSubmit(Object command) throws Exception { // TODO Auto-generated method stub Emp emp = (Emp)command; System.out.println(emp); return super.onSubmit(command); } @Override protected Map referenceData(HttpServletRequest request, Object command, Errors errors) throws Exception { Map<String,Object> model = new HashMap<String, Object>(); model.put("deptList",new String[]{"sales","manages"}); // TODO Auto-generated method stub return model; } @Override protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception { binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true)); } }
