快速搭建SSM框架

1）搭建Spring基础框架：

　　1.从maven仓库(网址：https://mvnrepository.com/)中引入spring核心包spring-context到pom.xml;　　

<!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.3.25.RELEASE</version>
</dependency>

　　2.在项目resource路径下创建一个spring.xml配置文件，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
</beans>

 

2）开启Spring MVC扩展功能：

　　1.从maven仓库引入spring-web架包以及spring-web-mvc架包到pom.xml；

<!-- https://mvnrepository.com/artifact/org.springframework/spring-web -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>4.3.25.RELEASE</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>4.3.25.RELEASE</version>
</dependency>

　　2.在项目web.xml中加入如下配置：

<context-param>
　　<param-name>contextConfigLocation</param-name>
　　<param-value>classpath:spring.xml</param-value>
</context-param>
<servlet>
　　<servlet-name>dispatcher</servlet-name>
　　<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
　　<init-param>
　　　　<param-name>contextConfigLocation</param-name>
　　　　<param-value></param-value>
　　</init-param>
　　<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
　　<servlet-name>dispatcher</servlet-name>
　　<url-pattern>/**</url-pattern>
</servlet-mapping>
<listener>
　　<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

　　3.同时将spring.xml修改如下，配置以开启MVC功能和包扫描：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd ">
<!-- 开启MVC -->
<mvc:annotation-driven/>
<!-- IOC容器自动化扫描，处理控制器和服务层 -->
<context:component-scan base-package="此处修改为控制器所在包路径"></context:component-scan>
<context:component-scan base-package="此次修改为服务层所在包路径"></context:component-scan>
</beans>

　　4.进行到此建议写一个控制器和页面进行访问测试，无误后继续mybatis的整合。

3）整合MyBatis：

　　1.从maven仓库引入mybatis、mybatis-spring、数据库驱动(mysql)的依赖包到pom.xml

<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.5.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring -->
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.3.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>6.0.6</version>
</dependency>

　　2.在resource下创建mybatis自己的xml配置文件mybatis.xml，内容如下：

<?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>
</configuration>

　　3.在spring.xml配置文件中增加mybatis整合配置：dataSource，SqlSessionFactoryBean，MapperScannerConfigurer三个bean。

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
　　<property name="driverClassName" value="此处修改为数据库驱动类路径" />
　　<property name="url" value="此处修改为数据库地址路径" />
　　<property name="username" value="此处修改为数据用户名" />
　　<property name="password" value="此处修改为数据库密码" />
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
　　<property name="dataSource" ref="dataSource" />
　　<property name="configLocation" value="classpath:mybatis.xml"></property>
　　<property name="mapperLocations" value="此处修改为扫描mapper的xml配置文件所在位置" />
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
　　<property name="basePackage" value="此处修改为mapper接口对应的包路径" />
　　<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
