SSM整合
1. 创建Maven项目，导入依赖

</dependencies>注意：若想要把Mapper的映射文件放在src/main/java目录下，则要在pom.xml文件中添加以下配置
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
</build>2. 在 resources文件夹下创建相应配置文件
2.1 applicationContext.xml
<?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"

<!-- 引入database.properties属性文件 -->
<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">

</bean>
<!-- 配置数据源dataSource -->

<!-- 使用mybatis-plus的MybatisSqlSessionFactoryBean

<!-- 加载mapper所在的包 -->

<!-- 扫描mapper接口所在的位置 -->

<!-- 定义事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 开启注解式事务 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>注意：不管使用了src/main/java还是src/main/resource的方法，都要在对应的路径下创建Mapper.xml映射文件，否则SSM环境搭建好了之后会启动不了
2.2 db.properties
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8
jdbc.user = root

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration

<settings>

<!-- 配置文件解析器对象，要求id名称必须是multipartResolver -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 设置文件上传限制大小为10M -->
<property name="maxUploadSize" value="10485760"/>
</bean>
</beans>2.6 根据路径创建Mapper文件
根据applicationContext.xml文件的mapperLocations属性，在对应的路径下创建映射文件，该文件夹用于存放Mapper.xml文件
3. 修改webapp的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">
<!-- 设置欢迎界面 -->
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
<!-- 加载spring配置文件 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 上下文参数配置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 使用*号通配符，通配符前面的字符要一致 -->
<param-value>classpath:applicationContext*.xml</param-value>
</context-param>
<!-- 加载springmvc配置文件 -->
<servlet>
<!-- servlet名称，名称自定义，名称唯一 -->
<servlet-name>springmvc</servlet-name>
<!-- 前端控制器，SpringMVC核心控制器 -->
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- web项目启动，立即加载springmvc配置文件 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- springmvc配置文件位置 -->
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<!-- servlet名称，名称自定义 -->
<servlet-name>springmvc</servlet-name>
<!-- 访问路径-->
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 配置过滤器 -->
<!--配置解决中文乱码的过滤器-->
<filter>
<filter-name>encodingFilter</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>
<!--配置过滤器的url映射路径-->
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>4. 根据配置文件，创建相应的包结构
com.eobard.entity
com.eobard.dao
com.eobard.service
com.eobard.controller
....省略其它包
