一.需求分析
1.1 項目包含的功能
使用SSM框架開發一個博客系統，這個博客相當於個人博客，所以並沒有用戶註冊這個功能，在創建數據庫的時候，可以直接寫入一個用戶，使用這個用戶登錄。
這個博客系統可以概括前臺（向大家展示）和後臺（自己管理）兩個部分。
後臺主要完成的功能：
- 登錄（用戶密碼登錄）
- 查看全部文章
- 寫文章
- 文章分類管理
- 文章標籤管理
- 頁面管理（站點地圖，文章歸檔，留言板，申請）
- 公告管理
- 評論管理
- 用戶管理
- 設置（菜單管理和博客信息管理）
前臺主要要完成的功能：
- 顯示所有文章，顯示熱評文章，顯示網站信息，顯示評論等等
- 留言
後期如果添加啥功能，會及時補充。
二 數據庫搭建
在搞清要完成的功能後，就知道數據庫需要創建幾張表，和表中的數據是什麼樣的。現在給出創建數據SQL。

三.創建Web工程
3.1 使用idea創建Maven項目
3.1.1 新建項目
1.創建新項目，選擇Maven項目：
2.填寫GroupId（域名.公司名.項目名）、Artifacted(模塊名)
3.選擇maven解壓的路徑、配置文件（這次的項目不適用本地的Maven和其倉庫）
4.選擇工作空間
5.創建成功，目錄結構如下：
6.在main底下創建兩個目錄:java,resources
7.點Project Struct，設置源碼文件夾和資源文件夾
8.爲了便於管理文件，在WEB-INF底下new一個Directory，命名view，再將index.jsp剪切進去
3.1.2 編輯pom.xml文件

轉存失敗重新上傳取消轉存失敗重新上傳取消3.2 配置web.xml文件（要注意的是下面的配置都是基礎配置，後面可能還會添加）
在之前的Spring+SpringMVC+MyBatis-整合文章中，我們知道web.xml要做下面的工作：
①配置Spring容器啓動；
②配置SpringMVC前端控制器；
③配置字符編碼過濾器；
④支持REST風格的過濾器。
在本次的項目中：
⑤因爲我們使用了Druid連接池，還需要配置這個過濾器。
⑥還需要配置Log4j。
編碼如下：

3.5 Spring基礎配置（spring-mybatis.xml）
外部配置文件db.properties:
#Mysql
mysql.url=jdbc:mysql://localhost:3306/forest_blog?serverTimezone=UTC
mysql.username=root
mysql.password=password
spring-mybatis.xml文件要做的事情：
①導入數據源配置文件dbconfig.properties
②數據源配置
③ 配置MyBatis操作數據庫
④配置事務控制器，讓它控制數據源連接的關閉與提交
⑤開啓基於註解的事務，寫切入點表達式和事務建議
⑥配置事務建議，在其中配置事務屬性，例如需要切入的方法

<!--1.導入數據源配置文件-->
<context:property-placeholder location="classpath:db.properties"/>
<!--2.配置數據源：druid連接池-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<!--基礎屬性url,username,password-->
<property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
<property name="url" value="${mysql.url}"/>
<property name="username" value="${mysql.username}"/>
<property name="password" value="${mysql.password}"/>

<property name="maxPoolPreparedStatementPerConnectionSize" value="20" />
<!-- 配置監控統計攔截的filters，去掉後監控界面sql無法統計 -->
<property name="filters" value="stat" />
</bean>
<!--3.配置MyBatis操作數據庫-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--數據庫連接池-->
<property name="dataSource" ref="dataSource"/>
<!--加載MyBatis全局配置文件-->
<property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>
<!--加載MyBatis的映射文件所在的位置-->
<property name="mapperLocations" value="classpath*:mapper/" />
<!--指定需要使用別名的PO類所在的包-->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
<!--5.基於註解的事務-->
<aop:config>
<!--配置切點表達式-->
