搭建過程：
通常idea建立工程的過程數據庫
打開idea ---> File ---> new ---> project ---> maven --->apache
create from archetype ---> maven-archetype-webapp ---> 接下來通常默認便可bootstrap
最後在main目錄下新建java文件夾，而且mark as source root。
首先建立以下的目錄結構便可：
├── java
│ └── com
│ └── hisen
│ ├── dao
│ │ └── BookDao.java
│ ├── entity
│ │ └── Book.java
│ ├── service
│ │ ├── BookService.java
│ │ └── impl
│ │ └── BookServiceImpl.java
│ └── web
│ └── BookController.java
├── resources
│ ├── jdbc.properties
│ ├── logback.xml
│ ├── mapper
│ │ └── BookMapper.xml
│ ├── mybatis-config.xml
│ └── spring
│ ├── spring-dao.xml
│ ├── spring-service.xml
│ └── spring-web.xml
└── webapp
├── index.jsp
└── WEB-INF
├── jsp
│ ├── detail.jsp
│ └── list.jsp
└── web.xml
第一步：添加Spring、Spring MVC、Mybatis的依賴
都配有詳細的說明，這裏再也不重複
詳情請看pom.xml
第二步：添加數據庫配置文件
├── resources │ ├── jdbc.properties
建立數據庫配置文件，內容以下
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://127.0.0.1:3306/booksystem?useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=hisen
這裏須要建立一個數據庫，名爲：booksystem
建表語句以下：
CREATE TABLE `book` ( `book_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '圖書ID', `name` varchar(100) NOT NULL COMMENT '圖書名稱', `number` int(11) NOT NULL COMMENT '圖書數量', `detail` varchar(200) NOT NULL COMMENT '圖書描述', PRIMARY KEY (`book_id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='圖書表'
表結構以下：
+---------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------+--------------+------+-----+---------+----------------+ | book_id | bigint(20) | NO | PRI | NULL | auto_increment | | name | varchar(100) | NO | | NULL | | | number | int(11) | NO | | NULL | | | detail | varchar(200) | NO | | NULL | | +---------+--------------+------+-----+---------+----------------+
第三步：添加mybatis配置文件
├── resources │ ├── mybatis-config.xml
在resources目錄下新建文件：mybatis-config.xml
內容以下：
<?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>
<!-- 配置全局屬性 -->
<settings>
<!-- 使用jdbc的getGeneratedKeys獲取數據庫自增主鍵值 -->
<setting name="useGeneratedKeys" value="true" />
<!-- 使用列別名替換列名 默認:true -->
<setting name="useColumnLabel" value="true" />
<!-- 開啓駝峯命名轉換:Table{create_time} -> Entity{createTime} -->
<setting name="mapUnderscoreToCamelCase" value="true" />
</settings>
</configuration>
第四步：添加Spring配置文件
在resources/spring目錄下新建三個文件：
│ └── spring │ ├── spring-dao.xml │ ├── spring-service.xml │ └── spring-web.xml
詳細內容詳見：resources/spring/
第五步：添加logback配置文件
logback配置比log4j要簡單點，功能相似
├── resources │ ├── logback.xml
在resources文件夾下新建文件：logback.xml
<?xml version="1.0" encoding="UTF-8" ?>
<configuration debug="true">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<!--開啓debug日誌模式，在控制檯打印日誌-->
<root level="debug">
<appender-ref ref="STDOUT" />
</root>
</configuration>
第六步：建立DAO、entity
以下兩個文件：BookDao.java、Book.java
│ └── com │ └── hisen │ ├── dao │ │ └── BookDao.java │ ├── entity │ │ └── Book.java
詳細內容：BookDao.java
詳細內容：Book.java
建立測試類：
- 測試基類：查看代碼BaseTest.java
- BookDao：查看代碼BookDaoTest.java
- 測試：addBook （因爲沒有預先準備數據，因此就先添加）

- 測試:queryById

20:15:04.076 [main] DEBUG com.hisen.dao.BookDao.queryById - <== Total: 1
20:15:04.088 [main] DEBUG org.mybatis.spring.SqlSessionUtils - Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@6f3187b0]
Book{bookId=101, name='活着0', number=100, detail='描述0'}
以此類推，就很少寫了
第七步：建立mybatis mapper文件
在resources/mapper/目錄下建立：resources/mapper/BookMapper.xml
在mapper文件中須要用到第六步的內容
第八步：建立service
├── service │ ├── BookService.java │ └── impl │ └── BookServiceImpl.java
具體內容：service
- 建立測試類：BookServiceImplTest
- BookServiceImplTest：查看代碼BookServiceImplTest.java
- 測試：getById
20:19:58.871 [main] DEBUG o.m.s.t.SpringManagedTransaction - JDBC Connection [com.mchange.v2.c3p0.impl.NewProxyConnection@37fb0bed] will not be managed by Spring
20:19:58.885 [main] DEBUG com.hisen.dao.BookDao.queryById - ==> Preparing: SELECT book_id, name, number, detail FROM book WHERE book_id = ?
20:19:58.974 [main] DEBUG com.hisen.dao.BookDao.queryById - ==> Parameters: 101(Long)
20:19:59.004 [main] DEBUG com.hisen.dao.BookDao.queryById - <== Total: 1
20:19:59.011 [main] DEBUG org.mybatis.spring.SqlSessionUtils - Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@2bec854f]
Book{bookId=101, name='活着0', number=100, detail='描述0'}
第九步：建立controller
└── web
└── BookController.java
具體內容：BookController.java
第十步：建立jsp頁面以及配置web.xml
頁面主要使用了bootstrap
└── webapp
├── index.jsp
└── WEB-INF
├── jsp
│ ├── detail.jsp
│ └── list.jsp
└── web.xml
