准备环境

1、创建数据库

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');

2、创建maven项目，添加web支持，导入所需依赖

                    **/*.properties
                    **/*.xml
                
                false
            
            
                src/main/resources
                
                    **/*.properties
                    **/*.xml
                
                false
            
        
    

3、创建基本结构

创建pojo、dao、service、controller包

配置资源文件

mybatis-config.xml

applicationContext.xml

数据库配置文件database.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=root

3、编写配置文件和接口以及实现类

编写mybatis配置文件

编写实体类Books

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;

}

在Dao层写入接口

public interface BookMapper {
//    增加
    int addBook(Books books);
//    删除
    int deleteBookById(@Param("bookId") int id);
//    更新
    int updateBook(Books books);
//    查询
    Books queryBookById(int id);
//    查询所有
    List queryAllBook();
}

编写对应的Mapper.xml文件

    
        insert into ssmbuild.books (bookName, bookCounts, detail)
        values (#{bookName},#{bookCounts},#{detail});
    
    
        delete from ssmbuild.books where bookID=#{bookId}

    
    
        update ssmbuild.books
        set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID=#{bookID}

    
    
        select *
        from ssmbuild.books where bookID=#{bookID};
    
    
        select *
        from ssmbuild.books;
    

编写Service层接口

public interface BookService {
    //    增加
    int addBook(Books books);
    //    删除
    int deleteBookById(int id);
    //    更新
    int updateBook(Books books);
    //    查询
    Books queryBookById(int id);
    //    查询所有
    List queryAllBook();

}

编写service实现类

public class BookServiceImpl implements BookService{
    private BookMapper bookMapper;

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

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

    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

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

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

    public List queryAllBook() {
        return bookMapper.queryAllBook();
    }
}

4、Spring整合mybatis

spring-dao.xml

spring整合service层          spring-service.xml

5、springmvc层

编写web.xml

    
        DispatcherServlet
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:applicationContext.xml
        
        1
    
    
        DispatcherServlet
        /
    

    
        encodingFilter
        
            org.springframework.web.filter.CharacterEncodingFilter
        
        
            encoding
            utf-8
        
    
    
        encodingFilter
        /*
    

    
    
        15
    

编写spring-mvc.xml

spring整合文件 applicationContext.xml

6、编写控制类和视图层

package com.kun.controller;

import com.kun.pojo.Books;
import com.kun.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.RequestMapping;

import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;
    @RequestMapping("/allBook")
    public String list(Model model){
        List list  = bookService.queryAllBook();
        model.addAttribute("list",list );
        return "allBook";
    }
    @RequestMapping("/toAddBook")
    public String toAdd(){
        return "toAddBook";
    }
    @RequestMapping("/addBook")
    public String addBook(Books books){
        System.out.println(books);
        bookService.addBook(books);
        return "redirect:/book/allBook";  //重定向
    }
//    修改界面
    @RequestMapping("/toUpdateBook")
    public String update(int id,Model model){
        Books books = bookService.queryBookById(id);
        model.addAttribute("QBook",books);
        return "updateBook";
    }
    @RequestMapping("/updateBook")
    public String updateBook(Books books){
        System.out.println("update"+books);
        bookService.updateBook(books);
        return "redirect:/book/allBook";
    }

   // 删除书籍
    @RequestMapping("/deleteBook")
    public String delete(int id){
        bookService.deleteBookById(id);
        return "redirect:/book/allBook";
    }
}
