# 准备工作

数据库创建：

```sql
CREATE DATABASE `ssmbuild`;
 
USE `ssmbuild`;
 
DROP TABLE IF EXISTS `books`;
 
CREATE TABLE `books` (
  `bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
  `bookName` VARCHAR(100) NOT NULL COMMENT '书名',
  `bookCounts` INT(11) NOT NULL COMMENT '数量',
  `detail` VARCHAR(200) NOT NULL COMMENT '描述',
  KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8
 
INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES 
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
```

```



# 配置基本框架 包

在com.dai 下面分别建立controller、mapper、pojo、service

controller：前后端控制实现。

mapper：用于mybatis和数据库操作的实现

pojo：数据库对应的实现类（字段名和数据库一致）

service：事务的调用实现



# 连接数据库

先配置一个数据库的database.properties文件

```properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456
```



再配置mybatis-config.xml来控制数据库

```java
<?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>


    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>

<!--    配置数据源，交个spring做-->
    <typeAliases>
        <package name="com.dai.pojo"/>
    </typeAliases>

    <mappers>
        <mapper class="com.dai.mapper.BookMapper"/>
    </mappers>



</configuration>
```





在利用spring容器创建一个spring到文件来获取mybatis-config.xml并完成数据库连接

```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

<!--    管理数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>
<!--    连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

<!--    sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
<!--        绑定mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

<!--    配置dao接口扫描包,动态的实现dao接口可以注入到spring容器中！-->

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--        注入sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!--扫描dao的包-->
        <property name="basePackage" value="com.dai.mapper"/>

    </bean>

</beans>
```





# 编写实体类

在pojo包下创建和数据库字段一一对应的实体类

```java
package com.dai.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {

    private int bookID;
    private String bookName;
    private int bookCounts;
    private  String detail;

}
//使用了注解的无参和有参和lombok插件来自动配置相关参数
```



# 配置spring层面

配置applicationContext.xml

```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="spring-dao.xml"/>
    <import resource="spring-service.xml"/>
    <import resource="spring-mvc.xml"/>

</beans>
```



创建mapper包下mapper接口

```java
package com.dai.mapper;

import com.dai.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {

    int addBook(Books books);

    int deleteBook(@Param("bookId") int id);

    int updateBook(Books books);

    Books queryBookById(@Param("bookId") int id);

    List<Books> queryAllBooks();

    Books queryBookName(@Param("bookName") String name);

}
```



xml配置文件实现mapper接口完成IOC

```xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dai.mapper.BookMapper">
    
    <insert id="addBook" parameterType="Books">
        insert into ssmbuild.books(bookName, bookCounts, detail)
        values (#{bookName},#{bookCounts},#{detail});
    </insert>

    <delete id="deleteBook" parameterType="int">
        delete from ssmbuild.books
        where bookID=#{bookId}
    </delete>

    <update id="updateBook" parameterType="books">
        update ssmbuild.books set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID=#{bookID}
    </update>

    <select id="queryBookById" resultType="Books">
        select  * from ssmbuild.books
        where bookID=#{bookId}
    </select>

    <select id="queryAllBooks" resultType="Books">
        select  * from ssmbuild.books
    </select>

    <select id="queryBookName" resultType="Books">
        select * from ssmbuild.books
        where  bookName=#{bookName}
    </select>

</mapper>
```









配置spring-dao层来绑定mybatis文件 配置sqlSessionFactory 

将mapper接口注入到spring容器中

```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

<!--    管理数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>
<!--    连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

<!--    sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
<!--        绑定mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

<!--    配置dao接口扫描包,动态的实现dao接口可以注入到spring容器中！-->

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--        注入sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!--扫描dao的包-->
        <property name="basePackage" value="com.dai.mapper"/>

    </bean>

</beans>
```



# 配置service层

在service包下创建接口并用实现接口

```java
package com.dai.service;

import com.dai.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookService {
    int addBook(Books books);

    int deleteBook(int id);

    int updateBook(Books books);

    Books queryBookById(int id);

    List<Books> queryAllBooks();

    Books queryBookName(String name);
}
```

```java
package com.dai.service;

import com.dai.mapper.BookMapper;
import com.dai.pojo.Books;
import lombok.Lombok;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public class BookServiceImpl implements BookService{

    //Service调用mapper层，组合
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper){
        this.bookMapper=bookMapper;
    }


    @Override
    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    @Override
    public int deleteBook(int id) {
        return bookMapper.deleteBook(id);
    }

    @Override
    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    @Override
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    @Override
    public List<Books> queryAllBooks() {
        return bookMapper.queryAllBooks();
    }

    @Override
    public Books queryBookName(String name) {
        return bookMapper.queryBookName(name);
    }
}
```



最后将service层面注册到spring容器中

```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">

<!--    扫描包-->
    <context:component-scan base-package="com.dai.service"/>

<!--    将所有业务类注入到spring可以通过配置或者注解实现-->
    <bean id="BookServiceImpl" class="com.dai.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

<!--    声明事务配置-->
    <bean id="TransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

<!--    aop事务支持-->

</beans>
```





# 配置controller层

在controller包下使用注解@Contreoller实现自动注入到spring层中

```java
package com.dai.controller;

import com.dai.pojo.Books;
import com.dai.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.ArrayList;
import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {

    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;


    //查询全部书籍
    @RequestMapping("/allBook")
    public String list(Model model){

        List<Books> list= bookService.queryAllBooks();
        model.addAttribute("list",list);
        return "allBook";
    }

    //跳转增加页面
    @RequestMapping("/toAddBook")
    public String toAddPaper(){
        return "addBook";
    }

    //添加书籍的请求
    @RequestMapping("/addBook")
    public String addBook(Books books){
        bookService.addBook(books);
        return "redirect:/book/allBook";
    }

    //跳转到修改界面
    @RequestMapping("/toUpdate")
    public String toUpdatePaper(int id,Model model){
        Books books = bookService.queryBookById(id);
        model.addAttribute("QBook",books);
        System.out.println(books);
        return "Update";
    }

    //修改书籍
    @RequestMapping("/update")
    public String UpdatePaper(Books books){
        System.out.println("updateBook------"+books);
        bookService.updateBook(books);
        return "redirect:/book/allBook";
    }

    //删除书籍
    @RequestMapping("/delete/{bookId}")
    public String deletePaper(@PathVariable("bookId") int id){
        System.out.println("delete--------");
        bookService.deleteBook(id);

        return  "redirect:/book/allBook";
    }

    //查询书籍
    @RequestMapping("/queryBook")
    public String queryBook(String queryBookName,Model model){
        System.out.println("查询----------------");
        Books books = bookService.queryBookName(queryBookName);
        List<Books> list=new ArrayList<>();
        list.add(books);
        System.err.println(books);
        if(books==null){
            list= bookService.queryAllBooks();
            model.addAttribute("error","未查到");
        }
            model.addAttribute("list",list);

        return "allBook";
    } 
}
```

配置spring-mvc中

1.注解驱动

2.扫描包

3.视图解析器

```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
<!--    扫描包-->
    <context:component-scan base-package="com.dai.controller"/>
<!--    注解驱动-->
    <mvc:annotation-driven/>
<!--    静态资源过滤-->
    <mvc:default-servlet-handler/>
<!--    视图解析器-->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>
```



# 配置web层面

配置web.xml:

1.配置DispatcherServlet（spring中的调度功能）

2.配置乱码过滤

3.配置session延时

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

        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

<!--    Session-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

</web-app>
```





创建在WEB-INF下面创建jsp包，包类是controller类中跳转的目标

前端三个jsp文件

# 总结

1.先配置maven包依赖，数据库文件，和mybatis文件和数据相连。

2.根据具体功能实现创建包结构,配置applicationContext.xml

3.根据数据文件创建一一对应的实体类

4.先在mapper层下创建相应功能的接口，然后利用xml文件进行实现。

5.然后在mybatis-config.xml文件下配相应的接口，在注入到spring-dao层中

6.在service中创建功能的接口和实现类，实现类利用mapper层实现功能。

7.创建spring-service.xml文件来在将实现类进行注入，并配置事务（防止提交不成功）。

8.配置controller包中类，使用注解@Controller来完成该类自动注入，这层用于前端页面的跳转和视图解析。

9.配置spring-mvc层，在配置文件中先配置注解驱动，在配置静态资源过滤，最后配置视图解析器。

10.将mapper层，springmvc，service层的文件全部注入到applicationContext文件中，实现统一控制。

10.先添加web框架，在WEB-INF下创建相应的包结构，配置web.xml（配置DispatcherServlet实现视图调度，绑定applicationtionContext.xml文件，配置乱码过滤）

11.完成前端页面jsp的编写。
