本章记录一下Spring、SpringMVC、Mybatis整合的配置操作–小白篇  
SSM框架主要在于搭建resources文件里的配置文件，配置好了写逻辑代码就很方便  
配置jdbc.properties-----这里写连接数据库的配置

##驱动类
    mysql.driverClass=com.mysql.cj.jdbc.Driver
    ##########jdbc:mysql://服务器地址:端口号/数据明?mysql8.0的操作
    mysql.url=jdbc:mysql://localhost:3306/ssmvip03?useSSL=true&serverTimezone=UTC
    ###数据库用户名
    mysql.username=root
    ###数据库密码
    mysql.password=root

配置myBatis-config.xml -----MyBatis的配置

<?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>
    	
        <properties resource="classpath:jdbc.properties"/>
    	
        <typeAliases>
        	
            <package name="com.gtl.pojo"/>
        </typeAliases>
    
        <environments default="development">
            <environment id="development">
                <transactionManager type="JDBC"/>
                <dataSource type="POOLED">
                    <property name="driver" value="${mysql.driverClass}"/>
                    <property name="url" value="${mysql.url}"/>
                    <property name="username" value="${mysql.username}"/>
                    <property name="password" value="${mysql.password}"/>
                </dataSource>
            </environment>
        </environments>
    
        <mappers>
        	
            <package name="com.gtl.mapper"/>
        </mappers>
    </configuration>

配置applicationContext.xml-----Spring的xml配置整合Mybatis

<?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 https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    
        
        <context:property-placeholder location="classpath:jdbc.properties"/>
        
        <context:component-scan base-package="com.gtl.service"/>
        
        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="${mysql.driverClass}"/>
            <property name="url" value="${mysql.url}"/>
            <property name="username" value="${mysql.username}"/>
            <property name="password" value="${mysql.password}"/>
        </bean>
        
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"/>
        </bean>
        
        <tx:annotation-driven transaction-manager="transactionManager"/>
        
        <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            
            <property name="typeAliasesPackage" value="com.gtl.pojo"/>
            
            <property name="mapperLocations" value="classpath:com/gtl/mapper/*.xml"/>
        </bean>
    
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="com.gtl.mapper"/>
            <property name="sqlSessionFactoryBeanName" value="sessionFactory"/>
        </bean>
    </beans>

配置SpringMVC.xml-----SpringMVC的配置

<?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" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        <context:component-scan base-package="com.gtl.controller"/>
        
        <mvc:default-servlet-handler/>
        
        <mvc:annotation-driven/>
    
        
        
        
        
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            
            <property name="prefix" value="/WEB-INF/"/>
            
            <property name="suffix" value=".jsp"/>
        </bean>
    
        
        <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
            
            <property name="defaultEncoding" value="uft-8"/>
            
            <property name="maxUploadSizePerFile" value="19243435"/>
            
            <property name="maxUploadSize" value="321493275409327"/>
        </bean>
    
        
        <mvc:interceptors>
            <mvc:interceptor>
                
                
                <mvc:mapping path="/**"/>
                
                <mvc:exclude-mapping path="/user/login"/>
                <mvc:exclude-mapping path="/user/myLogin"/>
                
                <bean class="com.gtl.config.MyHandlerInterceptor" />
            </mvc:interceptor>
        </mvc:interceptors>
    </beans>

以上配置完成,就完成了SSM的配置  
下面配置服务器  
web.xml的配置

<?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-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
            <init-param>
                <param-name>encodingFilter</param-name>
                <param-value>UTF-8</param-value>
            </init-param>
        </filter>
        <filter-mapping>
            <filter-name>encodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>
    
    
        <servlet>
            <servlet-name>dispatcherServlet</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:SpringMVC.xml</param-value>
            </init-param>
        </servlet>
    
        <servlet-mapping>
            <servlet-name>dispatcherServlet</servlet-name>
            
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
        
        <context-param>

            <param-value>classpath:applicationContext.xml</param-value>
        </context-param>
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
    
    
    </web-app>
