SSM框架整合配置詳解(spring,spring mvc,mybatis)

當今SSM框架已經成為了一種主流,其中spring,spring mvc和mybatis框架的功能很強大,給我們程式設計師節省了很多力氣,可以說這三種框架簡直就是我們程式設計師的福音,但是我們都知道,框架在自身帶來便捷的同時,也存在很多的配置檔案,更別說當三個框架整合的時候那就更加的困難了,所以我將這三個框架的環境搭建做了一下整理,希望可以給初學者一點引導.
搭建一個SSM專案主要分為以下幾個步驟:
1.建立一個web專案
2.匯入jar包(maven和手動)
其中用到的主要jar包有:(注意,因為版本之間存在不相容情況,所以對於初學者強烈建議使用一下版本)
spring4.37(context,mvc,jdbc,tx),jsckson2.81,mybatis3.4.5,
mytatis-spring1.3.1,druid1.0.14,mysql-connection5.0.8
commons-fileupload1.3.2+Apache poi3.13
3.建立java類
com.tarena.dao 介面
com.tarena.service 業務的介面
com.tarena.service.impl 業務介面的實現
com.tarena.controller springmvc的controller類
com.tarena.entity 例項類,序列化
com.tarena.vo 值物件,序列化
com.tarena.util 工具
4.配置檔案
a.專案入口web.xml
b.spring.xml 配置spring容器
c.spring_mvc.xml 配置springmvc容器
d.spring_mybatis.xml 配置mybatis
5.跑專案
6.新增專案靜態資源(html,css,js,image,video等)
7.跑專案
8.邊寫程式碼,邊除錯

下面就將每一步的程式碼貼上

  • 1.建立一個web專案
    我建立的maven專案,注意是war專案

  • 2.匯入jar包(maven和手動)

    a.專案入口web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</filter>
	<filter-mapping>

		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- spring mvc的入口 載入spring mvc 前端控制器 restful -->
	<!-- restful模式,必須注意在spring_mvc.xml中配置,刨除靜態資源 -->

</web-app>

b.spring.xml 配置spring容器

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

c.spring_mvc.xml 配置springmvc容器

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

</beans>

d.spring_mybatis.xml 配置mybatis

這是spring-mybatis的清單檔案
因為spring沒有整合mybatis,所以mybatis自己向spring靠攏

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

	</bean>
	<!-- 例項化MyBatis的SqlSessionFactoryBean物件-->
	<!--mybatis配置,讀取配置檔案(掃描配置檔案)-->
    <bean id="sqlSessionFactory"
        class="org.mybatis.spring.SqlSessionFactoryBean"

    <!-- spring 事務管理開始 -->	
    
    <!-- Spring jdbc 的事務管理器 -->
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="alibabaDataSource"/>
    </bean>
    
    <!-- 掃描事務有關的註解@Transactional -->
    <tx:annotation-driven transaction-manager="txManager"/>
   		
    <!-- Spring事務管理結束 -->
</beans>

mybatis的總清單檔案

<?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>
	
	</typeAliases>
	
	
</configuration>

這樣整個專案就算基本搭建完成了
搭建完之後的樣子是下面這樣的:
在這裡插入圖片描述

其中mapper裡面兩個xml是mybatis的對映檔案.還有conf中的mysql.properties和page.properties是屬性檔案,這個根據自己的實際情況去配置,我就不贅述了.
然後就可一啟動Tomcat了,如果出現下面的資訊就表明你配置成功了,
在這裡插入圖片描述

到這就萬事大吉了!
