转眼一学期过去了，总结一下ssm框架的整合，望各位coder指出不足。

一、导包

        </dependency>
        <!--spring-mybatis整合包-->
        <dependency>

        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>

        <!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.2.3</version>
        </dependency>

    </dependencies>

二、编写JDBC配置文件（jdbc.propertise）

jdbc.className = com.mysql.cj.jdbc.Driver
jdbc.url = jdbc:mysql://118.178.143.144:3306/ssmCourse?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC&useSSL=false&allowMultiQueries=true
jdbc.user = ssmCourse
jdbc.password = LekArx2mpnyDbRhh

三、整合Spring-MyBatis框架(application.xml)

1、配置注解扫描（注意：只扫描@Service和@Dao注解）

<!--只扫描Service和dao的注解 -->
    <context:component-scan base-package="com.projectName">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

2、加入JDBC配置文件

<!--加入jdbc配置文件-->
    <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>

3、在spring里配置数据源

<!--把mybatis的权利交给spring-->
<!--配置连接池-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
    <property name="driverClassName" value="${jdbc.className}"/>
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.user}" />
    <property name="password" value="${jdbc.password}" />
    <!--事务是否自动提交-->
    <property name="defaultAutoCommit" value="false"/>
</bean>

4、配置sqlSessionFactory(将sqlSession的创建交给spring)

<!--配置sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--自动扫描mapper.xml 文件-->
        <property name="mapperLocations" value="classpath:mapper/UserDao.xml"></property>
        <!--简化mapper.xml里面实体类的全限定名-->
        <property name="typeAliasesPackage" value="com.projectName.pojo"/>
    </bean>

5、配置事务管理器

<!--事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

6、配置dao层接口所在的包

<!--配置dao层接口所在的包-->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.projectName.dao"/>
    </bean>

7、配置文件头

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

四、整合SpringMVC（springMVC.xml）

1、配置注解扫描（注意：只扫描@Controller）

<!--开启注解扫描，只扫描controller-->
    <context:component-scan base-package="com.projectName.controller">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

2、启动Spring MVC的注解功能，完成请求和注解POJO的映射（）

    <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
        <mvc:annotation-driven />

3、过滤静态资源(还需再web.xml里配置servlet-mapping，见下文)

<!--静态资源默认serlvet配置解决静态资源访问问题（常用,适用于多种服务器）-->
    <mvc:default-servlet-handler/>

4、配置视图解析器

<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/WEB-INF/jsp/" />
        <!-- 后缀 -->
        <property name="suffix" value=".jsp" />
</bean>

5、配置拦截器

注意：这里要指明拦截路径和拦截器（该java类需实现HandlerInterceptor接口或WebRequestInterceptor接口

<!--拦截器-->
    <mvc:interceptors>
        <mvc:interceptor>
            <!--拦截路径-->
            <mvc:mapping path="/welcome"/>
            <!--实际拦截器-->
            <bean class="interceptor.LoginInterceptor"></bean>
        </mvc:interceptor>
    </mvc:interceptors>

6、配置mapper.xml(例子)

<!DOCTYPE mapper
        PUBLIC "-//mybati.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.projectName.dao.UserDao">
    <select id="login" parameterType="com.projectName.pojo.User" resultType="int">
        select count(*) from user where userName=#{userName} and password=#{password}
    </select>
</mapper>

7、配置文件头

<?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 http://www.springframework.org/schema/context/spring-context-4.3.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">
</beans>

五、编写web.xml配置文件（该文件放在WEB-INF下）

1、加载spring

<!--加载Spring-->
    <!--配置监听器,默认只加载web-inf目录下的applicationContext.xml-->
    <!--但是我们的文件在resources文件夹下-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!--设置spring配置文件路径-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

2、加载SpringMVC(含过滤静态资源)

<!--前端控制器-->
    <display-name>Archetype Created Web Application</display-name>
    <servlet>
        <servlet-name>spring-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--加载springmvc.xml配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springMVC.xml</param-value>
        </init-param>
        <!--启动服务器时，创建该servlet-->
        <load-on-startup>1</load-on-startup>
    </servlet>
	<!--使用默认的静态资源处理Servlet处理静态资源(涉及spring-mvc.xml, web.xml)-->
  	<servlet-mapping>
    	<servlet-name>default</servlet-name>
    	<url-pattern>*.js</url-pattern>
    	<url-pattern>*.css</url-pattern>
    	<url-pattern>*.jpg</url-pattern>
        <url-pattern>*.png</url-pattern>
  	</servlet-mapping>
    <servlet-mapping>
        <servlet-name>spring-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

3、配置中文乱码过滤器

<!--配置中文乱码过滤器-->
    <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>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/</url-pattern>
    </filter-mapping>

4、配置文件头

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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">
</web-app>
