idea搭建ssm框架(spring+springmvc+mybatis)：

先创建一个maven工程：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 3][]

到这里项目创建完成。

下面我们来创建文件夹：

在main下new 一个directory名为java和resourses

选择java点击右键

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 4][]

选择resourses单击右键

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 5][]

创建具体的包，在java下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 6][]

包建好之后就来集成spring的一些基础的包

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>

然后需要用到数据库就需要有mysql和mybatis的jar包：

<dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis</artifactId>
        <version>3.4.6</version>
    </dependency>
    
    
    <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.38</version>
    </dependency>

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>

mybatis需要和spring整合，所以我们需要一个整合的包

<dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis-spring</artifactId>
        <version>1.3.2</version>
    </dependency>

然后这里我们采用的是传统的jsp视图，然后我们在家几个包：

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>
    
    
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>

在使用数据库中我们会使用数据库连接池再加一个包：

<dependency>
        <groupId>commons-dbcp</groupId>
        <artifactId>commons-dbcp</artifactId>
        <version>1.4</version>
    </dependency>

因为需要解析json数据我们需要阿里巴巴的json包

<dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
        <version>1.2.47</version>
    </dependency>

到这里我们基本的包已经引进完毕了，然后我们来写springmvc的配置在resources下新建一个包叫spring，然后新建springmvc的配置文件，叫spring-mvc.xml

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 7][]

内容如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 8][]

在web-inf目录下创建view文件夹![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 9][]

在下面创建一个login.jsp

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 10][]

然后需要在新建一个spring-maybis整合的配置文件spring-maybis.xml，还在spring目录下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 11][]

文件内容如下：

<?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:p="http://www.springframework.org/schema/p"

        </bean>
    
        
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            
            <property name="driverClassName" value="${driver}"/>
            <property name="url" value="${url}"/>
            <property name="username" value="${username}"/>

            <property name="minIdle" value="${minIdle}"></property>
            
            <property name="maxWait" value="${maxWait}"></property>
        </bean>
    
        
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            
            <property name="mapperLocations" value="classpath:mapper/*.xml"/>
        </bean>
    
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="com.vrv.dao"/>
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        </bean>
    
        
        <bean id="transactionManager"
              class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"/>
        </bean>
    
    
        
        
    
        
        
        
        
        
        
        
        
        
        
        
        
        
        
    
        
        
        
        
        
    
        
        
        
        
        
        
        
    </beans>

为了更加容易的更换数据库配置我们新建一个jdbc.properties文件，在resources目录下，里面填写数据库配置：

driver=com.mysql.jdbc.Driver
    #driver=com.mysql.cj.jdbc.Driver
    #mytest为我本地的数据库名
    url=jdbc:mysql://localhost:3306/teaching_manage
    #url=jdbc:mysql://192.168.220.139:3306/teaching_manage
    username=root
    #下面输入自己数据库的密码
    password=123456
    #定义初始连接数
    initialSize=1
    #定义最大连接数
    maxActive=20
    #定义最大空闲
    maxIdle=20
    #定义最小空闲
    minIdle=1
    #定义最长等待时间
    maxWait=60000

因为mybatis是半自动化的orm(以对象的方式操作数据库)，所以我们需要自己写mybatis的映射文件，现在在resourses目录下新建一个mapper文件夹:

mybatis扫描这个目录下的所有文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hfal9jXzEyMw_size_16_color_FFFFFF_t_70 12][]

最后我们需要在web.xml文件里面加载这两个配置文件，同时配置字符集监听，和前端控制器

内容如下：

<!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
            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_3_0.xsd"
            version="3.0"
            metadata-complete="true">
      <display-name>Archetype Created Web Application</display-name>
    
    
      
      <filter>
        <filter-name>encoding-filter</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>encoding-filter</filter-name>
        
        <servlet-name>springDispatcherServlet</servlet-name>
      </filter-mapping>
    
      
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/spring-mybatis.xml</param-value>
      </context-param>
    
      
      
      
      <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:spring/spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
      </servlet>
    
      
      <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>*.do</url-pattern>
      </servlet-mapping>
    
      
      
      
    </web-app>

下面对基本的包概念进行说明：

字符集监听器：org.springframework.web.filter.CharacterEncodingFilter

主要用来限制整个工程的字符集的。

前端控制器：org.springframework.web.servlet.DispatcherServlet

是spring用来接收用户请求的同时分配用户请求给控制器(controller)来控制请求处理
