[SSM] 整合spring springmvc mybatis SSM框架搭建

项目地址：https://github.com/and826826/ssm

下面是使用maven在idea2019.3.1下搭建SSM的过程.
搭建步骤:
1.在pom文件下添加依赖。依赖可多不可少。
2.在web.xml文件里面引入spring和springmvc的配置文件。
3.编写spring和springmvc的配置文件。
4.编写mapper文件操作数据库。

具体步骤如下：
在idea中新建一个maven项目

next后输入自己的项目名，再next选择maven仓库，推荐你使用自己的maven仓库，如果没有也可选择默认的。

idea新生成的项目目录可能会不够完整
完整的目录结构如下图：

你可能没有Java和resource，自己新建同名的包就行了。新建之后如果包颜色不对，就需要手动设置包的属性。右击你要修改的包，然后选择下图中箭头中的选项。

目录结构正确后，我们引入依赖。
下图是pom.xml文件。

我在搭建的时候发现很多作者是在pom文件开头的properties中写入了spring的版本，在后面引入依赖时直接用${spring.version}来规定版本，这样所有spring依赖的版本都是相同的，这是一种很好的做法，避免了依赖的版本差异可能导致的问题。

配置web.xml文件

新建applicationContext_mvc.xml：

新建applicationContext.xml：

<!--	Spring的配置文件,这里主要配置业务逻辑-->

<!--dataSource(已经搞定) sqlsessionFactory(已经搞定)
sqlSession（可以暂时不管）  mapper（已经搞定） 事务（已经搞定） -->
<!--配置数据源 -->

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
<property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/user?serverTimezone=UTC"/>
<property name="username" value="root"/>
<property name="password" value="open"/>
</bean>
<!--配置sqlSessionFactory  与mybatis整合 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml" />
</bean>

<!--一劳永逸的映射器mapper 将mybatis接口实现加到ioc容器  -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ssm.mapper" />
</bean>

<!--事务管理 -->
<!--	 <tx:jta-transaction-manager />-->
<!--	<bean  id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">-->
<!--		<property name="dataSource" ref="dataSource"></property>-->
<!--	</bean>-->

</beans>

至此，springmvc和spring的核心文件编写完成。
下面使用一个例子来测试：
在controller下新建了一个类

hellocontroller代码如下

package com.ssm.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.ssm.mapper.UserMapper;
import com.ssm.service.impl.UserDaoServiceImple;

@Controller//

public class HelloController  {

@Autowired
UserDaoServiceImple daoService;

@RequestMapping("/hello")
public  ModelAndView method01() {
System.out.println("hello测试");

return  null;

}

}

将项目部署到tomcat服务器上，在游览器里访问hello，你就能看见服务器端打印出了"hello 测试"，游览器跳到了一个空白页面。
