打开 IDEA 工具，通过 File -> New -> Project，新建项目，或者直接在 IDEA 欢迎页面点击新建项目

“ GroupID ” 是项目组织唯一的标识，实际对应 Java 的包结构，是 main 目录里 Java 的目录结构，

“ ArtifactID ” 是项目的唯一的标识符，实际对应项目的名称，也就是项目根目录的名称，名为 ssmdemo 。

一路next 对于maven 这里不详细介绍

  2.     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  3.     <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

  14.     <maven.test.skip>true</maven.test.skip>
  15.   </properties>

完善目录结构

通过 Maven 骨架生成的项目结构只有 main 目录及其目录下的 webapp 目录，这两个目录并不完善，缺少了 java 目录和 resource 目录，因此需要在 main 目录新建这两个目录，过程如下：

main -> New -> Directory -> 新建 Java 目录 main -> New -> Directory -> 新建 Resources 目录

之后需要右键选择 “ Mark Directory as ” ，分别将 java 目录和 resource 目录设置为 “ 源码根目录 ” 和 “ 配置文件目录 ”

1708247-20190610143256141-1642770074.png

之后在 resources 目录下新建 mappers 目录用来存放 MyBatis 的 mapper 文件，整个项目的目录结构就完成了，如下所示：

  1. ssmdemo                                ——项目名称
  2.      ├── src/main/java                  ——Java 源码根目录
  3.             ├── controller              ——控制层目录
  4.             ├── dao                     ——dao层目录
  5.             ├── entity                  ——实体层目录
  6.             ├── service                 ——业务层目录
  7.                 └── impl                ——业务实现类目录
  8.             └── utiles                  ——工具类目录
  9.      ├── src/main/resources             ——配置文件根目录
  10.             └── mappers                 ——mapper文件目录
  11.      ├── src/main/webapp                ——网站 Web 资源
  12.      └── pom.xml                        ——pom文件

整合spring

整合mybatis

resource 目录下创建 mybatis-config.xml

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE configuration
  3.         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  4.         "http://mybatis.org/dtd/mybatis-3-config.dtd">
  5. <configuration>
  6.     <typeAliases>
  7.         <package name="com.ssm.demo.entity"/>
  8.     </typeAliases>
  9. </configuration>

整合springmvc

resource 目录下创建 spring-mvc.xml 

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
  6.         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
  8.     <!-- 使用注解的包，包括子集 -->
  9.     <context:component-scan base-package="com.ssm.demo.controller"/>
  11.     <!-- 视图解析器 -->
  12.     <bean id="viewResolver"
  13.           class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  14.         <property name="prefix" value="/"/>
  15.         <property name="suffix" value=".jsp"></property>
  16.     </bean>
  17. </beans>

最重要的是在web.xml中进行配置

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
  3.          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  4.          id="WebApp_ID" version="2.5">
  5.   <display-name>ssm-demo</display-name>
  8.   <!--Start 欢迎页-->
  9.   <welcome-file-list>
  10.     <welcome-file>index.jsp</welcome-file>
  11.   </welcome-file-list>
  12.   <!--End 欢迎页-->
