### SSM 实训笔记 -09- 使用 Spring MVC + JDBC Template 实现登录（maven） ###

**本篇内容：**

（1）使用 Spring MVC 替代原来的令人脑壳儿疼的 Servlet。

**（2）先看下 Spring MVC 对比 Servlet 的简化程度：**

**（3）项目的功能和之前一样：**

*  登录、查询、删除、添加

![在这里插入图片描述][20190108175541614.gif]

### 一、创建数据库，插入数据 ###

（建议名称一致）

（1）安装 MySQL 请百度或参考：[MySQL 安装 + 入门大全 + 常用命令合集][MySQL _ _ _ _]

（2）打开 cmd ，登录 mysql 的 root 用户，创建 studb 数据库，创建表 tb\_user ：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMTQ3ODYz_size_16_color_FFFFFF_t_70 1][]

（3）显示表结构，插入 3 条用户数据：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMTQ3ODYz_size_16_color_FFFFFF_t_70 2][]

（4）数据库 studb，表 tb\_user 创建好了。

### 二、创建项目、配置 ###

（1）创建项目就不多说了，请参考：[Spring 笔记 -05- 创建 Maven Web 项目 + Tomcat 及目录结构配置][Spring _ -05- _ Maven Web _ _ Tomcat]

（2）上面的创建项目内容全部需要

**（如果看过上一篇请不要忽略 pom 配置）**

（3）配置 Maven 的 pom.xml 文件，添加 Spring MVC 和 Spring JDBC Template 依赖：

<dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-webmvc</artifactId>
          <version>5.1.3.RELEASE</version>
        </dependency>
    
        
    
        <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-context</artifactId>
          <version>5.1.3.RELEASE</version>
        </dependency>
    
          
          <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>spring-jdbc</artifactId>
              <version>5.1.3.RELEASE</version>
          </dependency>

（4）在 resources 下创建 啊 applicationContext.xml 文件：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMTQ3ODYz_size_16_color_FFFFFF_t_70 3][]

（5）填写如下配置，自行修改为自己的数据库信息：

<?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.xsd">
        
    
        
        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="url" value="jdbc:mysql://localhost:3306/studb?serverTimezone=UTC"></property>
            <property name="username" value="root"></property>
            <property name="password" value="xiaopengwei"></property>
            <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"></property>
        </bean>
    
        
        <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
            <property name="dataSource" ref="dataSource"></property>
    
        </bean>
    
    </beans>

（6）下面需要先做一件事，就是在 js 目录中，引入 Bootstrap3 和 jQuery

注意：只能是 Bootstrap3 版本：

**配置步骤：**

*  安装 Node.js ，因为要使用 npm
 *  在项目中 js 目录，右键 Open in Explorer 可以打开该目录，并复制
 *  在 cmd 进入项目的 js 目录
 *  使用命令：

npm install bootstrap3

npm install jQuery

### 三、项目源代码： ###

先根据目录结构创建好项目，准备粘贴代码。

**整体项目目录结构：**

**前端页面：**  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMTQ3ODYz_size_16_color_FFFFFF_t_70 4][]

**后端目录及文件：**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMTQ3ODYz_size_16_color_FFFFFF_t_70 5][]

**WEB-INF 下面的文件的配置**

**（1）web.xml 文件的配置：**

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >
    
    <web-app>
      <display-name>Archetype Created Web Application</display-name>
    
      <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      </servlet>
      <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>*.do</url-pattern>
      </servlet-mapping>
    </web-app>

（2）springmvc-servlet.xml 文件：  
（名称很重要，必须以这个样式命名，【web.xml 中的】-servlet，不然的话需要进行配置）

<?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" 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.xsd">
           
    
    <context:component-scan base-package="com.servlet"></context:component-scan>
    
    </beans>

**前端页面源代码：**
