配合哔哩哔哩视频学习【SSM 框架】SpringMVC+Spring+Mybatis SSM 整合+实战+源码17-18集
7.SSM整合-客户添加
7.1.在CustomerController里面添加方法
package com.ssmlcx.controller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.ssmlcx.domain.Customer;
import com.ssmlcx.service.CustomerService;
@Controller
@RequestMapping("/customer")
public class CustomerController {
//注入业务对象
@Resource
private CustomerService customerService;
/* @RequestMapping("/test")
public String test()
{
return "test";
}*/
/**
* 跳转到input.jsp
*/
@RequestMapping("/input")
public String input()
{
return "input";
}
/**
* 保存客户
*/
@RequestMapping("/svae")
public String save(Customer customer)
{
customerService.saveCustomer(customer);
return "succ";
}
}
7.2.编写input.jsp录入客户页面
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>客户录入页面</title>
<meta http-equiv="pragma" content="no-cache">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<form action="${pageContext.request.contextPath}/customer/save.action" method="post">
客户姓名：<input type="text" name="name"/><br/>
客户性别：
<input type="radio" name="gender" value="男"/>男
<input type="radio" name="gender" value="女"/>女<br/>
客户：<input type="text" name="name"/><br/>
客户手机：<input type="text" name="telephone"/><br/>
客户姓名：<input type="text" name="name"/><br/>
客户住址：<input type="text" name="address"/><br/>
<input type="submit" value="保存">
</form>
</body>
</html>
这时发现页面传到Controller，中文数据就乱码，这时可以在web.xml加多编码过滤器
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>01.mybatis</display-name>
<!-- 配置springMVC编码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 启动springMVC -->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 参数：读取 spring-mvc.xml-->
<init-param>

</init-param>
</servlet>
<servlet-mapping>

<url-pattern>*.action</url-pattern>
</servlet-mapping>
<!-- 启动spring -->

<!-- 修改路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
