1.创建如下mysql脚本
1 drop table if exists book_info; 2 3 create table if not exists book_info( 4 book_id int(10) primary key auto_increment, 5 book_name varchar(50) not null, 6 book_author varchar(50) not null, 7 book_publish varchar(50) not null, 8 book_page int(10) not null, 9 book_price double(10,2) not null, 10 creation_time date not null 11 ); 12 13 insert into book_info 14 (book_name,book_author,book_publish,book_page,book_price,creation_time) 15 values 16 (\'Java与模式\',\'闫磊\',\'电子工业出版社\',1100,97.00,\'2017-01-01\'), 17 (\'Java核心\',\'(美)Cay S.Horstmann\',\'机械工业出版社\',678,333.00,\'2017-01-02\'), 18 (\'Java编程思想\',\'(美)Bruce Exkel\',\'机械工业出版社\',590,75.00,\'2017-01-03\'), 19 (\'TCP/IP详解\',\'(美)W.Ricahr Steves\',\'机械工业出版社\',205,90.20,\'2017-01-04\'), 20 (\'什么是数学\',\'R.阿朗\',\'复旦大学出版社\',521,42.00,\'2017-01-05\') 21 ; 22 23 select * from book_info;
2.创建项目Spring_Mybatis_Exam9
3.导入jar文件，注意：mysql是jar文件版本：mysql-connector-java-5.1.7-bin.jar或更高版本
4.在src下的com.pojo包下创建BookInfo.java
1 package com.pojo; 2 import java.io.Serializable; 3 public class BookInfo implements Serializable{ 4 private static final long serialVersionUID = 1L; 5 private Integer book_id ; 6 private Integer book_page ; 7 private Double book_price ; 8 private String book_name ; 9 private String book_author ; 10 private String book_publish ; 11 private String creation_time; 12 13 public BookInfo() { 14 } 15 16 public BookInfo(Integer bookPage, Double bookPrice, String bookName, 17 String bookAuthor, String bookPublish, String creationTime) { 18 book_page = bookPage; 19 book_price = bookPrice; 20 book_name = bookName; 21 book_author = bookAuthor; 22 book_publish = bookPublish; 23 creation_time = creationTime; 24 } 25 26 public BookInfo(Integer bookId, Integer bookPage, Double bookPrice, 27 String bookName, String bookAuthor, String bookPublish, 28 String creationTime) { 29 book_id = bookId; 30 book_page = bookPage; 31 book_price = bookPrice; 32 book_name = bookName; 33 book_author = bookAuthor; 34 book_publish = bookPublish; 35 creation_time = creationTime; 36 } 37 public Integer getBook_id() { 38 return book_id; 39 } 40 public void setBook_id(Integer bookId) { 41 book_id = bookId; 42 } 43 public Integer getBook_page() { 44 return book_page; 45 } 46 public void setBook_page(Integer bookPage) { 47 book_page = bookPage; 48 } 49 public Double getBook_price() { 50 return book_price; 51 } 52 public void setBook_price(Double bookPrice) { 53 book_price = bookPrice; 54 } 55 public String getBook_name() { 56 return book_name; 57 } 58 public void setBook_name(String bookName) { 59 book_name = bookName; 60 } 61 public String getBook_author() { 62 return book_author; 63 } 64 public void setBook_author(String bookAuthor) { 65 book_author = bookAuthor; 66 } 67 public String getBook_publish() { 68 return book_publish; 69 } 70 public void setBook_publish(String bookPublish) { 71 book_publish = bookPublish; 72 } 73 public String getCreation_time() { 74 return creation_time; 75 } 76 public void setCreation_time(String creationTime) { 77 creation_time = creationTime; 78 } 79 @Override 80 public String toString() { 81 return "BookInfo [book_author=" + book_author + ", book_id=" + book_id 82 + ", book_name=" + book_name + ", book_page=" + book_page 83 + ", book_price=" + book_price + ", book_publish=" 84 + book_publish + ", creation_time=" + creation_time + "]"; 85 } 86 }

6.在src下的com.mapper包下创建BookInfoMapper.java
1 package com.mapper; 2 import java.util.List; 3 import com.page.PageUtil; 4 import com.pojo.BookInfo; 5 public interface BookInfoMapper { 6 //分页查询 7 List<BookInfo> findPage(PageUtil pageutil); 8 //查询总条数 9 Integer getTotalCout(); 10 //根据主键查询对象 11 BookInfo findByPrimaryKey(Integer key); 12 //添加对象 13 Integer insertBookInfo(BookInfo bookInfo); 14 //根据主键修改对象 15 Integer updatePrimaryKey(BookInfo bookInfo); 16 //根据主键删除 17 Integer deletePrimaryKey(Integer key); 18 }

11.在src下的com.service包下创建BookInfoService.java
1 package com.service; 2 import java.util.List; 3 import com.page.PageUtil; 4 import com.pojo.BookInfo; 5 public interface BookInfoService { 6 //分页查询 7 List<BookInfo> queryAll(PageUtil pageutil); 8 //查询总条数 9 Integer getTotalCout(); 10 //根据主键查询对象 11 BookInfo findBookInfo(Integer key); 12 //添加对象 13 Integer saveBookInfo(BookInfo bookInfo); 14 //根据主键修改对象 15 Integer editBookInfo(BookInfo bookInfo); 16 //根据主键删除 17 Integer deleteBookInfo(Integer key); 18 }
12.在src下的com.service.impl包下创建BookInfoServiceImpl.java
