8 三层代码和数据库

8.0 数据库和实体类

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');

实体类
package org.ymx.Entity;

public class Books {
private int bookID;
private String bookName;
private int bookCounts;
private String detail;
public Books() {

}
public Books(int bookID, String bookName, int bookCounts, String detail) {
    this.bookID = bookID;
    this.bookName = bookName;
    this.bookCounts = bookCounts;
    this.detail = detail;
}

public int getBookID() {
    return bookID;
}

public void setBookID(int bookID) {
    this.bookID = bookID;
}

public String getBookName() {
    return bookName;
}

public void setBookName(String bookName) {
    this.bookName = bookName;
}

public int getBookCounts() {
    return bookCounts;
}

public void setBookCounts(int bookCounts) {
    this.bookCounts = bookCounts;
}

public String getDetail() {
    return detail;
}

public void setDetail(String detail) {
    this.detail = detail;
}

}

8.1 Dao层

接口
package org.ymx.Dao;

import org.ymx.Entity.Books;

import java.util.List;

public interface booksMapper {
//增加一个Book
int addBook(Books book);

//根据id删除一个Book
int deleteBookById(int id);

//更新Book
int updateBook(Books books);

//根据id查询,返回一个Book
Books queryBookById(int id);

//查询全部Book,返回list集合
List<Books> queryAllBook();

}

Mapper

<?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"> <mapper namespace="org.ymx.Dao.booksMapper">

<!--增加一个Book-->
<insert id="addBook" parameterType="Books">
  insert into ssmbuild.books(bookName,bookCounts,detail)
  values (#{bookName}, #{bookCounts}, #{detail})

</insert>

<!--根据id删除一个Book-->
<delete id="deleteBookById" parameterType="int">
  delete from ssmbuild.books where bookID=#{bookID}

</delete>

<!--更新Book-->
<update id="updateBook" parameterType="Books">
  update ssmbuild.books
  set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
  where bookID = #{bookID}

</update>

<!--根据id查询,返回一个Book-->
<select id="queryBookById" resultType="Books">
  select * from ssmbuild.books
  where bookID = #{bookID}

</select>

<!--查询全部Book-->
<select id="queryAllBook" resultType="Books">
  SELECT * from ssmbuild.books

</select> </mapper>

8.2 Service层

接口
package org.ymx.Service;

import org.ymx.Entity.Books;

import java.util.List;

public interface booksService {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
}

实现类
package org.ymx.Service;

import org.ymx.Dao.booksMapper;
import org.ymx.Entity.Books;

import java.util.List;

public class booksServiceImpl implements booksService{

private org.ymx.Dao.booksMapper booksMapper;

public void setBooksMapper(org.ymx.Dao.booksMapper booksMapper) {
    this.booksMapper = booksMapper;
}

public int addBook(Books book) {
    return booksMapper.addBook(book);
}

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

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

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

public List<Books> queryAllBook() {
    return booksMapper.queryAllBook();
}

}

8.3 Controller层

package org.ymx.Controller;

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 org.ymx.Entity.Books;

import java.util.List;

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

    @Autowired
    @Qualifier("booksServiceImpl")
    private org.ymx.Service.booksService booksService;

    @RequestMapping("/allBook")
    public String list(Model model) {
        List<Books> list = booksService.queryAllBook();
        model.addAttribute("list", list);
        return "allBook";
    }

}
