本文详细介绍了Spring、Spring MVC和Hibernate（SSH）框架的整合过程，包括项目结构、配置文件spring-mvc.xml和applicationContext.xml的设置，web.xml的DispatcherServlet配置，以及UserController、UserService和UserServiceImpl的具体实现，展示了如何通过SSH框架完成用户信息的保存和处理。

一、项目结构

在这里插入图片描述

二、导包

源码中有这些包
在这里插入图片描述

三、spring-mvc.xml

<?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" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd  
        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-4.1.xsd  
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd">
 
	<!-- 配置自动扫描包 -->
	<context:component-scan base-package="com.ssh" />
	<mvc:annotation-driven />
 
	<!-- 配置视图解析器 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/pages/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
</beans>

四、applicationContext.xml

<?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:tx="http://www.springframework.org/schema/tx"
	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-4.1.xsd  
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd">
 
	<!-- 配置自动扫描的包 -->
	<context:component-scan base-package="com.ssh">
		<!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>
</beans>

五、web.xml

<?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_3_0.xsd"
	id="WebApp_ID" version="3.0">
	<display-name>ssh</display-name>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
 
	<!-- 配置spring ioc容器 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:config/applicationContext.xml</param-value>
	</context-param>
 
	<!-- Bootstraps the root web application context before servlet initialization -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
 
	<!-- 配置springmvc 的DispatcherServlet -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:config/spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
 
	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
 
	<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>
</web-app>

六、UserController

package com.ssh.controller;
 
import javax.servlet.http.HttpServletRequest;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 
import com.ssh.service.UserService;
 
@Controller
@RequestMapping("/user")
public class UserController {
 
	@Autowired
	private UserService userService;
 
	@RequestMapping(value = "save")
	public String save(HttpServletRequest request) {
		String username = request.getParameter("username");
		String password = request.getParameter("password");
		System.out.println(username + " " + password);
		System.out.println("controller save...");
 
		userService.save();
		return "success";
	}
}

七、UserService

package com.ssh.service;
 
public interface UserService {
	void save();
}

八、UserServiceImpl

package com.ssh.service;
 
import org.springframework.stereotype.Service;
 
@Service
public class UserServiceImpl implements UserService {
 
	@Override
	public void save() {
		System.out.println("userservice save...");
	}
}

九、add.jsp

<%@ page language=“java” contentType=“text/html; charset=utf-8”
pageEncoding=“utf-8”%>

Insert title here

添加用户

十、success.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">
