2、完善配置文件

2.1、数据库配置文件db.properties

jdbc.url=jdbc:mysql://localhost:3306/xiaomissm?user=root&password=&useUnicode=true&characterEncoding=gbk&serverTimezone=Asia/Shanghai
jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.user=xxxx
jdbc.passward=xxxxxx

2.2、mybatis配置文件mybatisConfig.xml

2.3、spring配置文件applicationContext.xml

• applicationContext.xml

2.3.1 applicationContext_dao.xml

2.3.2 applicationContext_service.xml

2.3.3 applicationContext_trans.xml

2.4、springmvc配置文件springmvc.xml

2.5、web.xml配置

  Archetype Created Web Application
  
  
    contextConfigLocation
    classpath*:applicationContext.xml
  
  
    org.springframework.web.context.AbstractContextLoaderInitializer
  
  
  
    springmvc
    org.springframework.web.servlet.DispatcherServlet
      
    
      contextConfigLocation
      classpath*:springmvc.xml
    
  
  
    springmvc
    *.do
  

3、工具配置类

什么是工具配置类呢，在上文我们成功搭建了SSM的基本框架并成功的运行出来的helloworld程序；
当然，这样的程序是十分简单的，但他的配置却十分繁琐，这也是本篇文章的目的，提供基本工具配置模板而达到简单复用并快速实现搭建SSM的意义。

3.1、逆向工程generatorConfiguration

逆向生成dao/mapper/entity

逆向工程插件

 <!-- 具体插件，逆向工程的操作是以构建过程中插件形式出现的 -->
      <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.7</version>
        <!-- 插件的依赖 -->
        <dependencies>
          <!-- 逆向工程的核心依赖 -->
          <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.7</version>
          </dependency>
          <!-- MySQL驱动 -->
          <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql.version}</version>
          </dependency>
        </dependencies>
      </plugin>

3、 实际效果：
按照预期生成了dao\mapper\entity

log4j.rootCategory=debug, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
