ssm-book 整合案例

一：环境及要求

环境：

• IDEA最新版
• MySQL 5.7.19 
• Tomcat 9 
• Maven 3.6    

要求：

• 需要掌握 MyBatis；Spring；SpringMVC；MySQL数据库以及简单的前端知识 

二：项目编码

1：搭建数据库

1-1：创建一个数据库

 1 CREATE DATABASE `ssm-books`;
 2
 3 USE `ssm-books`;
 4
 5 CREATE TABLE `books` (
 6   `bookId` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
 7   `bookName` VARCHAR(100) NOT NULL COMMENT '书名',
 8   `bookNumber` INT(11) NOT NULL COMMENT '数量',
 9   `bookPrice` INT(20) NOT NULL COMMENT '价格',
10   KEY `bookId` (`bookId`)
11 ) ENGINE=INNODB DEFAULT CHARSET=utf8
12
13 INSERT  INTO `books`(`bookId`,`bookName`,`bookNumber`,`bookPrice`)VALUES
14 (1,'西游记',5,55),
15 (2,'水浒传',6,66),
16 (3,'三国演义',7,77);

1-2：创建数据库需要的database.properties

jdbc.Driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/ssm-books?useSSL=true&useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456

1-3：导入数据库驱动包

1 <dependency>
2       <groupId>mysql</groupId>
3       <artifactId>mysql-connector-java</artifactId>
4       <version>5.1.47</version>
5 </dependency>

1-4：IDEA关联数据库

2：编写数据库对应的实体类及Dao层

2-1：实体类  com.qsh.pojo.Books

 1 public class Books {
 2
 3     private int bookId;
 4     private String bookName;
 5     private int bookNumber;
 6     private int bookPrice;
 7
 8     public Books() {
 9     }
10
11     public Books(int bookId, String bookName, int bookNumber, int bookPrice) {
12         this.bookId = bookId;
13         this.bookName = bookName;
14         this.bookNumber = bookNumber;
15         this.bookPrice = bookPrice;
16     }
17
18     public int getBookId() {
19         return bookId;
20     }
21
22     public void setBookId(int bookId) {
23         this.bookId = bookId;
24     }
25
26     public String getBookName() {
27         return bookName;
28     }
29
30     public void setBookName(String bookName) {
31         this.bookName = bookName;
32     }
33
34     public int getBookNumber() {
35         return bookNumber;
36     }
37
38     public void setBookNumber(int bookNumber) {
39         this.bookNumber = bookNumber;
40     }
41
42     public int getBookPrice() {
43         return bookPrice;
44     }
45
46     public void setBookPrice(int bookPrice) {
47         this.bookPrice = bookPrice;
48     }
49
50     @Override
51     public String toString() {
52         return "Books{" +
53                 "bookId=" + bookId +
54                 ", bookName='" + bookName + '\'' +
55                 ", bookNumber=" + bookNumber +
56                 ", bookPrice=" + bookPrice +
57                 '}';
58     }
59 }

2-2：Dao层接口  com.qsh.dao.BookDao

 1 import org.apache.ibatis.annotations.Param;
 2 import com.qsh.pojo.Books;
 3 import java.util.List;
 4
 5 public interface BookDao {
 6
 7     //增加books
 8     int addBook(Books books);
 9
10     //通过id删除books
11     int delBookById(@Param("bookId") int bookId);
12
13     //更新books
14     int upBook(Books books);
15
16     //通过id获取books
17     Books allBookById(@Param("bookId") int bookId);
18
19     //获取全部books
20     List<Books> allBook();
21 }

2-3：编写接口对应的Mapper文件时需要导入MyBatis的包

1 <dependency>
2       <groupId>org.mybatis</groupId>
3       <artifactId>mybatis</artifactId>
4       <version>3.5.1</version>
5 </dependency>

2-4：编写BookMapper.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

    update books set bookName=#{bookName},bookNumber=#{bookNumber},bookPrice=#{bookPrice}

    select * from books where bookId=#{bookId}
</span><span style="color: #0000ff;">&lt;/</span><span style="color: #800000;">select</span><span style="color: #0000ff;">&gt;</span>
<span style="color: #008000;">&lt;!--</span><span style="color: #008000;">5.获取全部books</span><span style="color: #008000;">--&gt;</span>

</span><span style="color: #0000ff;">&lt;/</span><span style="color: #800000;">select</span><span style="color: #0000ff;">&gt;</span>
 
</mapper>

2-5：编写Mybatis-config.xml配置文件；配置别名，注册映射文件  

<?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>
 
<!--别名-->

<typeAliases>

<package name="com.qsh.pojo"/>

</typeAliases>
 
<!--关联映射文件-->

<mappers>

<mapper resource="com/qsh/dao/BookMapper.xml"/>

</mappers>
 
</configuration>

3：编写Service层的接口和实现类

3-1：接口  com.qsh.service.BookService

 1 import com.qsh.pojo.Books;
 2 import org.apache.ibatis.annotations.Param;
 3 import java.util.List;
 4
 5 public interface BookService {
 6
 7     //增加books
 8     int addBook(Books books);
 9
10     //通过id删除books
11     int delBookById(@Param("bookId") int bookId);
12
13     //更新books
14     int upBook(Books books);
15
16     //通过id获取books
17     Books allBookById(@Param("bookId") int bookId);
18
19     //获取全部books
20     List<Books> allBook();
21 }

3-2：实现类  com.qsh.service.BookServiceImpl

 1 import com.qsh.dao.BookDao;
 2 import com.qsh.pojo.Books;
 3 import java.util.List;
 4
 5 public class BookServiceImpl implements BookService {
 6
 7     //组合Dao层,设置一个set接口，方便spring管理
 8     private BookDao bookDao;
 9
10     public void setBookDao(BookDao bookDao) {
11         this.bookDao = bookDao;
12     }
13
14     @Override
15     public int addBook(Books books) {
16
17         return bookDao.addBook(books);
18     }
19
20     @Override
21     public int delBookById(int bookId) {
22         return bookDao.delBookById(bookId);
23     }
24
25     @Override
26     public int upBook(Books books) {
27
28         return bookDao.upBook(books);
29     }
30
31     @Override
32     public Books allBookById(int bookId) {
33
34         return bookDao.allBookById(bookId);
35     }
36
37     @Override
38     public List<Books> allBook() {
39         return bookDao.allBook();
40     }
41 }

4：Spring整合MyBatis

4-1：我们这里数据源使用c3p0连接池；先导入相关jar包

 1 <!--1.mybatis-spring整合包 -->
 2     <dependency>
 3       <groupId>org.mybatis</groupId>

35         <property name="basePackage" value="com.qsh.dao"/>
36     </bean>
37
38 </beans>

5：Spring整合service层

5-1：配置spring-service.xml

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

15         <property name="bookDao" ref="bookDao"/>
16     </bean>
17
18 </beans>

6：SpringMVC相关配置

6-1：配置web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3          xmlns="http://java.sun.com/xml/ns/javaee"

41
42 </web-app>

6-2：配置spring-mvc.xml

 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"

27     <context:component-scan base-package="com.qsh.controller"/>
28
29 </beans>

7：Spring配置整合文件，applicationContext.xml

7-1：我们将前面的spring-dao.xml   spring-service.xml   spring-mvc.xml 三个配置文件导入一个大的配置文件中，使其项目结构更加清晰，也更好管理

 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"

 6
 7     <import resource="spring/spring-dao.xml"/>
 8     <import resource="spring/spring-mvc.xml"/>
 9     <import resource="spring/spring-service.xml"/>
10
11 </beans>

8：编写BookController类

8-1：导入jsp和servlet的包

 1 <!--1.servlet -->
 2     <dependency>
 3       <groupId>javax.servlet</groupId>
 4       <artifactId>javax.servlet-api</artifactId>

13     </dependency>
14
15     <!-- 3.JSTL -->
