## 二.添加web工程 ##

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

#### 2.1在Project Structure中型添加一个web工程 ####

注意路径必须加上**src\\main\\webapp**放在此目录下

![d8fed377fd204a328de6376209bbe50f.png][]

#### 2.2配置web.xml ####

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
             version="4.0">
        
        
        <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>
            <init-param>
                <param-name>forceEncoding</param-name>
                <param-value>true</param-value>
            </init-param>
        </filter>
        
        <filter-mapping>
            <filter-name>CharacterEncodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>
    
        
    
        
        <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:SpringMVC.xml</param-value>
            </init-param>
            
            <load-on-startup>1</load-on-startup>
        </servlet>
    
        
        <servlet-mapping>
            <servlet-name>DispatcherServlet</servlet-name>
            
            <url-pattern>*.action</url-pattern>
        </servlet-mapping>
    
    
        
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        
        <context-param>
            <param-name>contextConfigLocation</param-name>
            
            <param-value>classpath:applicationContext-*.xml</param-value>
        </context-param>
    </web-app>

## 三.创建SpringMVC的配置文件 ##

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

#### 3.1配置SpringMVC.xml ####

方式1：用jsp时

方式2：用html时

## 四.搭建MyBatis环境 ##

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

#### 4.1创建属性文件jdbc.properties ####

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/xiaomissm?Unicode=true&;characterEncoding=utf-8&;useSSL=false
    jdbc.username=root
    jdbc.password=1234

#### 4.2创建MyBatis的核心配置文件mybatis-config.xml ####

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE configuration
            PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
     
    <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>
    
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>
    </plugins>
    </configuration>

#### 4.3创建日志文件log4j.xml ####

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
    
    <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
    
        <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
        <param name="Encoding" value="UTF-8" />
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%-5p %d{MM-dd HH:mm:ss,SSS}%m (%F:%L) \n" />
        </layout>
        </appender>
        <logger name="java.sql">
        <level value="debug" />
        </logger>
        <logger name="org.apache.ibatis">
        <level value="info" />
        </logger>
        <root>
        <level value="debug" />
        <appender-ref ref="STDOUT" />
        </root>
    </log4j:configuration>

#### 4.4创建Mapper接口和映射文件（若用逆向工程生成可忽略此步骤） ####

##### 4.4.1手动创建pojo类 #####

![628524bcb76a4751be6381c832339d63.png][]

##### 4.4.2创建Mapper接口 #####

![a825ed94339b4dff97bc9d4794bd2cfa.png][]

##### 4.4.3创建Mabatis的映射文件 #####

![62b0ff93409442ccac40763ac259f95e.png][]

**注意包名和文件名要一致**

![dd182ca53a1c4e14ad5fd7959d7eb01f.png][]

## 五.创建Spring的配置文件 ##

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

#### 5.1配置spring文件 ####

##### 5.1.1 方式一： #####

多个模块时，可以根据不同模块功能拆分开来写（例如：applicationContext-dao.xml和applicationContext-service.xml）

**①applicationContext-dao.xml**

**②applicationContext-service.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"

       <context:component-scan base-package="com.bjpowernode.service"></context:component-scan>
    
       
       <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
          <property name="dataSource" ref="dataSource"></property>
       </bean>
       
       <tx:advice id="myadvice" transaction-manager="transactionManager">
          <tx:attributes>

             <tx:method name="*get*" read-only="true"/>
             <tx:method name="*search*" read-only="true"/>
             
             <tx:method name-"*insert*" propagation"REQUIRED"/>
             <tx:method name="*save*" propagation="REQUIRED"/>
             <tx:method name="*add*" propagation"REQUIRED"/>

             <tx:method name="*drop*" propagation="REQUIRED"/>
             <tx:method name="*" propagation="SUPPORTS"/>
             
          </tx:attributes>
       </tx:advice>
       
       <aop: config>
          
          <aop: pointcut id="mypointcut" expression="execution(* com.bjpowernode.service.*.*(..))"/>
          <aop: advisor advice-ref-"myadvice" pointcut-ref="mypointcut "*/aop:advisor>
       </aop: config>
    </beans>

##### 5.1.2 方式二： #####

写到同一个spring.xml里

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <context:component-scan base-package="com.atguigu.ssm">
            
            <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>
    
        
        <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
        
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">

        </bean>
                        
    </beans>

## 六.MyBats的逆向工程生成pojo+mapper ##

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

#### 6.1在pom.xml文件中添加依赖和插件 ####
