springmvc中对普通Javabean属性的获取
设置两个简单Java类
public class Address {
private String province;
private String city;
public String getProvince() {
return province;
}
public void setProvince(String province) {
this.province = province;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
@Override
public String toString() {
return "Address [province=" + province + ", city=" + city + "]";
}
}
public class User {
private String name;
private String psw;
private String sex;
private Address address;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPsw() {
return psw;
}
public void setPsw(String psw) {
this.psw = psw;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
@Override
public String toString() {
return "User [name=" + name + ", psw=" + psw + ", sex=" + sex
+ ", address=" + address + "]";
}
}
关于springmvc基础jar的引入
在web.xml中配置
<?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"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!-- 非默认配置文件，启动时加载配置文件 --> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
springmvc.xml的配置如下
<?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: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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 包扫描--> <context:component-scan base-package="cn.zqq.controller"></context:component-scan> <!-- spring提供的视图转发 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 前缀 --> <property name="prefix" value="/WEB-INF/jsp/"></property> <!-- 后缀 --> <property name="suffix" value=".jsp"></property> </bean>
编写Controller
@Controller @RequestMapping("/test") public class controllerTest { @RequestMapping("/pojo") public String testPojo(User user) { System.out.println(user); return "success"; } ｝
对应的jsp表单请求
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>My JSP ‘success.jsp‘ starting page</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 action="test/pojo"> name<input type="text" name="name"><br> psw<input type="password" name="psw"><br> province<input type="text" name="address.province"><br> sex<input type="text" name="sex"><br> city<input type="text" name="address.city"><br> <input type="submit" value="submit"> </form> </body> </html>
对于级联属性，springmvc也是支持的，如代码所示，当用户请求时便可得到相应结果
结果如下
对于中文乱码，对应配置解码即可
springmvc封装了servlet的请求应用，进行映射
