大概需要配置的文件

在这里插入图片描述

第一步: 导入项目需要的基本依赖

                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include> **/*.xml</include>
                </includes>
            </resource>
        </resources>
    </build>
</project>

第二步: 配置连接数据库的信息

这里用的是c3p0连接池

#配置数据库的连接信息
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/biaoshu
jdbc.username=root
jdbc.password=123

第三步:日志配置文件

#指明日志输出的级别,输出的地方
log4j.rootLogger=info,stout
#日志在控制台上输出的格式
log4j.appender.stout=org.apache.log4j.ConsoleAppender
log4j.appender.stout.layout=org.apache.log4j.PatternLayout
log4j.appender.stout.layout.ConversionPattern=%5p [%t] - %m%n
# %p 优先级   %t 线程名   %m 代码中指定的消息   %n 回车换行符

第四步:mybatis的主配置文件

<?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>
    <plugins>
	    <!-- com.github.pagehelper为PageHelper类所在包名 -->
	    <plugin interceptor="com.github.pagehelper.PageInterceptor">
    </plugin>
</plugins>
    <settings>
        <!--开启懒加载(使用到的时候才进行加载) lazyLoadingEnable  aggressiveLazyLoading-->
        <!--①开启懒加载开关-->
        <setting name="lazyLoadingEnabled" value="true"/>
        <!--②将积极加载改为消极加载-->
        <setting name="aggressiveLazyLoading" value="false"/>
        <!--开启自动映射,partial表示只对非嵌套的resultMap进行自动映射-->
        <setting name="autoMappingBehavior" value="PARTIAL"/>
        <!--开启全局缓存开关(二级缓存) 默认就是true-->
        <setting name="cacheEnabled" value="true"/>
        <!--日志实现-->
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>

    <!--别名定义(该路径下的类就拥有一个别名,也就是类名首字母小写就是它的别名)-->
    <typeAliases>
        <package name="com.ssii.pojo"/>
    </typeAliases>

</configuration>

第五步:配置spring管理下的dao,applicationContext-dao.xm

<?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.引入静态属性文件(配置了数据库连接信息的文件)-->
    <context:property-placeholder location="classpath:db.properties"/>
    <!--2.配置数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxPoolSize" value="15"/>
    </bean>
    <!--3.配置mybatis最核心的sqlSessionFactory-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--加载mybatis的主配置文件-->
        <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"/>
        <!--数据源 -->
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--批量配置mapper接口:
    通过mapper扫描器,扫描某个包下的所有mapper接口,批量加载配置
    -->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--设置需要扫描的包-->
        <property name="basePackage" value="这里是你需要的被扫描的包"></property>
        <!--配置sqlSessionFactory对象-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>
</beans>

第六步:配置spring管理下service层的配置文件

applicationContext-service

<?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">
    <!--扫描service包,将service包下添加@Servcie注解的类添加到容器中-->
    <context:component-scan base-package="这里是你编写的service的包"></context:component-scan>
</beans>

第七步:配置spring管理下的事务文件

当然,可以直接在项目中使用事务注解,这样,就不用下面的配置文件了.

<?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:aop="http://www.springframework.org/schema/aop"
       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/aop https://www.springframework.org/schema/aop/spring-aop.xsd
 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
">
    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!--配置通知-->
    <tx:advice id="tx_advice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="insert*" propagation="REQUIRED" isolation="DEFAULT"/>
            <tx:method name="add*"></tx:method>
            <tx:method name="update*"></tx:method>
            <tx:method name="modify*"></tx:method>
            <tx:method name="delete*"></tx:method>
            <tx:method name="remove*"></tx:method>
            <tx:method name="get*" read-only="true"></tx:method>
            <tx:method name="select*" read-only="true"></tx:method>
            <tx:method name="query*" read-only="true"></tx:method>
        </tx:attributes>
    </tx:advice>

    <!--配置切面(使用了切点表达式)-->
    <aop:config>
        <aop:advisor advice-ref="tx_advice" pointcut="execution(* 这里一般写service的类所在包..*.*(..))"></aop:advisor>
    </aop:config>
</beans>

第八步:配置springMVC的配置文件

<?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"
       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">
    

    <!--配置扫描controller包下的所有以@Controller注解修饰的类-->
    <context:component-scan base-package="这里是控制器的所在类,你可以放一起写,也可以分开写"></context:component-scan>

    <!--配置注解驱动-->
    <mvc:annotation-driven></mvc:annotation-driven>

    <!--放行静态资源文件-->
    <mvc:default-servlet-handler></mvc:default-servlet-handler>

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

    <!--配置文件上传解析器 吐过需要,你就打开注释commons-io commons-fileupload-->
    <!--<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="10000000"></property>
    </bean>-->

</beans>

第九步:web.xml文件

<?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">

  <!--配置post提交中文乱码的过滤器-->
  <filter>
    <filter-name>characterEncoding</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>characterEncoding</filter-name>
    <url-pattern>*</url-pattern>
  </filter-mapping>

  <!--给监听器指定初始化参数,用于加载spring配置文件-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <!--classpath:spring/applicationContext-dao.xml,classpath:spring/applicationContext-tx.xml,classpath:spring/applicationContext-servcie.xml-->
    <param-value>classpath:spring/applicationContext-*.xml</param-value>
  </context-param>

  <!--配置监听器 加载spring配置文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--配置前端控制器-->
  <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:spring/springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>
