由于SSM框架学习都要去网上或者以前的项目拷贝相同的代码,所以我在此把自己用到的配置文件全放在这里,帮助自己,帮助别人

首先开始前导入依赖和处理静态资源导出问题

<dependencies>

        <!--Junit-->

        <dependency>

            <groupId>junit</groupId>

            <artifactId>junit</artifactId>

            <version>4.13.2</version>

        </dependency>

        <!--数据库驱动-->

        <dependency>

            <groupId>mysql</groupId>

            <artifactId>mysql-connector-java</artifactId>

            <version>5.1.49</version>

        </dependency>

        <!-- 数据库连接池 -->

        <dependency>

            <artifactId>c3p0</artifactId>

            <version>0.9.5.5</version>

        </dependency>

        <!--Servlet - JSP -->

            <version>2.2</version>

        </dependency>

        <dependency>

            <groupId>javax.servlet</groupId>

            <artifactId>jstl</artifactId>

            <version>1.2</version>

        </dependency>

        <!--Mybatis-->

        <dependency>

            <groupId>org.mybatis</groupId>

            <artifactId>mybatis</artifactId>

            <version>3.5.6</version>

        </dependency>

        <dependency>

            <groupId>org.mybatis</groupId>

            <artifactId>mybatis-spring</artifactId>

            <version>2.0.6</version>

        </dependency>

        <!--Spring-->

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-webmvc</artifactId>

            <version>5.3.5</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-jdbc</artifactId>

            <version>5.3.5</version>

        </dependency>

<!--        lombok-->

        <dependency>

            <groupId>org.projectlombok</groupId>

            <artifactId>lombok</artifactId>

            <version>1.18.20</version>

        </dependency>

    </dependencies>

<!--静态资源导出问题-->

    <build>

        <resources>

            <resource>

                <directory>src/main/resources/</directory>

                <includes>

                    <include>**/*.properties</include>

                    <include>**/*.xml</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.配置web.xml文件

web.xml文件需要配置三部分信息，spring、springmvc以及解决springmvc传值乱码的过滤器，分别如下：

2.1(web.xml) spring配置信息：

<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>

2.2 (web.xml) springmvc配置信息:

<!--    1.配置DispatcherServlet-->

<servlet>

    <servlet-name>springmvc</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

   <init-param>

     <param-name>contextConfigLocation</param-name>

     <param-value>classpath:springmvc-servlet.xml</param-value>

   </init-param>

   <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

    <servlet-name>springmvc</servlet-name>

    <url-pattern>/</url-pattern>

 </servlet-mapping>

<!-- 2.解决springmvc传递值乱码问题 -->

    <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>

    <filter-mapping>

        <filter-name>encodingFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

<!--3.Session过期时间-->

    <session-config>

        <session-timeout>15</session-timeout>

    </session-config>

3.配置mybatis-config.xml配置文件

<?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>

<!--配置数据源,交给spring去做-->

    <typeAliases>

        <package name="cn.dzp.pojo"/>

    </typeAliases>

    <mappers>

        <mapper class="cn.dzp.dao.BookMapper"/>

    </mappers>

</configuration>

4.配置spring-dao.xml的信息

数据库配置文件db.properties

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8

jdbc.username=root

jdbc.password=123456

<?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"

       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">

<!-- 1.关联数据库配置文件   -->

    <context:property-placeholder location="db.properties"/>

<!--    2.连接池-->

    <!--数据库连接池

        dbcp  半自动化操作  不能自动连接

        c3p0  自动化操作（自动的加载配置文件 并且设置到对象里面）

    -->

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

        <property name="driverClass" value="${jdbc.driver}"/>

        <property name="jdbcUrl" value="${jdbc.url}"/>

        <property name="user" value="${jdbc.username}"/>

        <property name="password" value="${jdbc.password}"/>

 <!-- c3p0连接池的私有属性 -->

        <property name="maxPoolSize" value="30"/>

        <property name="minPoolSize" value="10"/>

        <!-- 关闭连接后不自动commit -->

        <property name="autoCommitOnClose" value="false"/>

        <!-- 获取连接超时时间 -->

        <property name="checkoutTimeout" value="10000"/>

        <!-- 当获取连接失败重试次数 -->

        <property name="acquireRetryAttempts" value="2"/>

    </bean>

<!--    3.SqlSessionFactory-->

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<!--        注入数据库连接池-->

        <property name="dataSource" ref="dataSource"/>

        <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->

        <property name="configLocation" value="mybatis-config.xml"/>

    </bean>

<!--    4.配置dao接口扫描包,动态实现dao接口可以注入到spring容器中-->

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>

<!--        要扫描的dao包-->

        <property name="basePackage" value="cn.dzp.dao"/>

    </bean>

</beans>

5.配置spring-service.xml配置文件

<?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"

        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.xsd">

        <!-- 1.扫描service相关的bean -->

        <context:component-scan base-package="cn.dzp.service"/>

        <!--2.将我们所有的业务类,注入到spring,可以通过配置或者注解实现-->

        <bean id="BookServiceImpl" class="cn.dzp.service.BookServiceImpl">

            <property name="bookMapper" ref="bookMapper"/>

        </bean>

        <!--3.配置事务管理器-->

          <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<!--              注入数据库连接池-->

              <property name="dataSource" ref="dataSource"/>

          </bean>

        <!--4.aop事务支持-->

        </beans>

6.:spring-mvc.xml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

       http://www.springframework.org/schema/context/spring-context.xsd

       http://www.springframework.org/schema/mvc

       https://www.springframework.org/schema/mvc/spring-mvc.xsd">

<!--    配置springMVC-->

<!--    1.开启springMVC注解驱动-->

    <mvc:annotation-driven/>

<!--    2.静态资源默认servlet配置-->

    <mvc:default-servlet-handler/>

<!--    3.配置jsp,显示ViewResolver视图解析器-->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>

        <property name="prefix" value="/WEB-INF/jsp/"/>

        <property name="suffix" value=".jsp"/>

    </bean>

<!--    4.扫描web相关的bean-->

    <context:component-scan base-package="cn.dzp.controller"/>

</beans>

7.applicationContext.xml整合其他配置文件文件：

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

<beans xmlns="http://www.springframework.org/schema/beans"

              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

              xsi:schemaLocation="http://www.springframework.org/schema/beans

              http://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="spring-dao.xml"/>

    <import resource="spring-service.xml"/>

    <import resource="spring-mvc.xml"/>

</beans>

配置到此结束,希望能在编程之路上帮到自己!
