 9             <scope>test</scope>
10         </dependency>
11 
12         <!--freemarker支持-->
13         <dependency>

28             <version>1.1.1</version>
29         </dependency>

2.application.properties

1 spring.datasource.url=jdbc:mysql://localhost:3306/bookshop
2 spring.datasource.username=root
3 spring.datasource.password=123
4 spring.datasource.driver-class-name=com.mysql.jdbc.Driver

3.entity层

 1 public class Book {
 2 
 3     private Integer bookid;
 4 
 5     private String bookname;
 6 
 7     private Integer bookprice;
 8 
 9    
10 }

4.mapper层

1 public interface BookMapper {
2 
3     @Select("select * from book where bookname=#{bookname}")
4     public Book findByName(@Param("bookname") String bookname);
5 
6     @Insert("insert into book(bookname,bookprice) values (#{bookname},#{bookprice})")
7     public int insertBook(@Param("bookname") String bookname,@Param("bookprice") Double bookprice);
8 }

5.controller层

 1 @RestController
 2 public class BookController {
 3     @Autowired
 4     private BookMapper bookMapper;
 5 
 6     @RequestMapping("findByName")
 7     public Object findByName(String bookname){
 8         return bookMapper.findByName(bookname);
 9     }
10 
11     @RequestMapping("insert")
12     public String insert(String bookname,Double bookprice){
13         bookMapper.insertBook(bookname,bookprice);
14         return "success";
15     }
