ssm整合 idea+maven版

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

 

Pom中导入相关依赖

对于版本集中管理

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <spring.version>4.2.4.RELEASE</spring.version>

    <mybatis-spring.version>1.2.2</mybatis-spring.version>
    <maven.test.skip>true</maven.test.skip>
  </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 ”

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:

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

整合spring 

resource 目录下创建applicationContext.xml

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

        <property name="dataSource" ref="dataSource"/>
        <!-- 自动扫描mappers.xml文件 -->
        <!--<property name="mapperLocations" value="classpath:mappers/*.xml"></property>-->
        <!-- mybatis配置文件 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    </bean>

    <!-- DAO接口所在包名,Spring会自动查找其下的类 -->

        <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation"/>
    </aop:config>

</beans>

整合mybatis 

resource 目录下创建 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">
<configuration>
    <typeAliases>
        <package name="com.ssm.demo.entity"/>
    </typeAliases>
</configuration>

整合springmvc

resource 目录下创建 spring-mvc.xml 

<?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-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!-- 使用注解的包,包括子集 -->
    <context:component-scan base-package="com.ssm.demo.controller"/>

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

最重要的是在web.xml中进行配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         id="WebApp_ID" version="2.5">
  <display-name>ssm-demo</display-name>
