Spring、SpringMVC、Hibernate整合 ----超详细教程

一.数据库表

/*

Navicat MySQL Data Transfer

Source Server         : 本地连接

Source Server Version : 50720

Source Host           : localhost:3306

Source Database       : ssh_demo

Target Server Type    : MYSQL

Target Server Version : 50720

File Encoding         : 65001

Date: 2019-10-07 14:19:04

*/

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------

-- Table structure for `t_user`

-- ----------------------------

DROP TABLE IF EXISTS `t_user`;

CREATE TABLE `t_user` (

  `id` int(11) NOT NULL AUTO_INCREMENT,

  `address` varchar(255) DEFAULT NULL,

  `username` varchar(50) DEFAULT NULL,

  `phone` varchar(50) DEFAULT NULL,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;

-- ----------------------------

-- Records of t_user

-- ----------------------------

INSERT INTO `t_user` VALUES ('6', 'GZ', '张三', '13456789487');

INSERT INTO `t_user` VALUES ('7', 'GZ', '张三', '15674635267');

二.使用idea创建一个maven项目，然后创建如下的目录

三.各种配置文件如下

1.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"

         version="3.0">

  <!-- 地址为http://localhost:8080/  显示的默认网页-->

  <welcome-file-list>

    <welcome-file>/index.jsp</welcome-file>

  </welcome-file-list>

  <!--加载Spring的配置文件到上下文中去-->

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>

      classpath:applicationContext.xml

    </param-value>

  </context-param>

  <!-- spring MVC config start-->

  <servlet>

    <servlet-name>spring</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>

      <param-name>contextConfigLocation</param-name>

      <!-- 此处指向的的是SpringMVC的配置文件 -->

      <param-value>classpath:spring-mvc.xml</param-value>

    </init-param>

    <!--配置容器在启动的时候就加载这个servlet并实例化-->

    <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

    <servlet-name>spring</servlet-name>

    <url-pattern>/</url-pattern>

  </servlet-mapping>

  <!-- spring MVC config end-->

  <!-- Spring监听器 -->

  <listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <!--  字符集过滤  -->

  <filter>

    <filter-name>encodingFilter</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>

    <init-param>

      <param-name>forceEncoding</param-name>

      <param-value>true</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>encodingFilter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

</web-app>

四.启动tomcat

1.输入http://localhost:8080/user/saveUser结果如下

表中数据增加了一个用户

2.浏览器输入http://localhost:8080/user/getUsers
