7.配置文件(记得修改依赖包名）

1）在maven-dao中添加applicationContext-dao.xml，database.properties，mybatis.config.xml三个配置文件

applicationContext-dao.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"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="

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

    <!-- 扫描注解所在的包 -->
    <context:component-scan base-package="com.manong.dao"/>

<!-- <context:property-placeholder location="classpath:database.properties"/>-->

    <!-- 引入database.properties属性文件 -->

    <!-- 配置数据源dataSource -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <!--驱动-->
        <property name="driverClassName" value="${jdbc.driver}"/>
        <!--连接字符串-->
        <property name="url" value="${jdbc.url}"/>
        <!--数据库用户名-->
        <property name="username" value="${jdbc.user}"/>
        <!--数据库密码-->

        <!-- 加载SQL映射文件 -->
        <property name="mapperLocations" value="classpath:mapper/**/*.xml"/>
    </bean>

    <!-- 加载mapper所在的包 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 扫描mapper接口所在的位置 -->
        <property name="basePackage" value="com.manong.dao"/>
    </bean>



</beans>

database.properties

#\u6570\u636E\u5E93\u9A71\u52A8
jdbc.driver = com.mysql.cj.jdbc.Driver

jdbc.user = root
#\u6570\u636E\u5E93\u5BC6\u7801
jdbc.password = root

mybatis.config.xml

<?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">

    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">

            <property name="resonable" value="true"/>
        </plugin>

</configuration>

2）给maven-service添加applicationContext-service.xml文件

applicationContext-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"

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

    <!-- 扫描注解所在的包 ,管理service-->
    <context:component-scan base-package="com.manong.service"/>


    <!-- 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>

3）给maven-web添加springmvc.xml和log4j.properties文件

springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"

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


    <!-- 加载控制器所在的包 -->
    <context:component-scan base-package="com.manong.controller"/>

    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 视图前缀（页面在哪个目录下） -->
        <property name="prefix" value="/WEB-INF/jsp/"/>

    <mvc:resources mapping="/statics/**" location="/statics/"/>

    <!-- 开启注解支持 -->
    <mvc:annotation-driven>
        <mvc:message-converters>
            <!-- 配置编码字符集 -->
            <!-- 配置响应编码字符集 -->
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes">

                    </list>
                </property>
            </bean>

            <!-- 配置Jackson消息转换器 -->
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>


    <!-- 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>

log4j.properties

# rootLogger\u662F\u6240\u6709\u65E5\u5FD7\u7684\u6839\u65E5\u5FD7,\u4FEE\u6539\u8BE5\u65E5\u5FD7\u5C5E\u6027\u5C06\u5BF9\u6240\u6709\u65E5\u5FD7\u8D77\u4F5C\u7528

4）更新maven-web—>webapp---->WEB-INF—>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">


  <!-- 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 -->
  <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>

</web-app>

出现resources报错情况，在webapp同级创建一个resources文件夹即可，先这样办，之后项目会进行改进。
spring-mvc里的 mvc:resources及静态资源访问

5）clean文件，clean右侧所有文件

在这里插入图片描述
执行maven指令时失败，‘modules.module[10]’ specifies duplicate child module

8.测试

1.打开SQLyo创建gdb_hotel_Jt11.sql(文件名更改的时候记得在maven-dao/src/main/resources/database.properties的内容也要修改)，再其中创建一个user表，根据maven-entity创建的user.java建立一个user数据随便填一下。
在这里插入图片描述

2.测试tomcat

关于出现 Error creating bean with name ‘sqlSessionFactory’ defined in URL的错误
还在修bug中…
