扫描接口（BoopMapping）
@SpringBootApplication
@MapperScan("dao")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
- application.properties: 添加自己的服务器
spring.datasource.url=
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
重点：全局配置
mybatis.mapper-locations=classpath:mapping/BookMapping.xml
mybatis.type-aliases-package=pojo
- BookMapping 接口
@Repository
public interface BookMapping {
void addBook(Book book);
Book loadBook(int id);
List<Book> findAllBook(Book book);
void updataBook(@Param("id") int id, @Param("book") Book book);
Book deleteBook(int id);
}
- 新建类controller
@RestController
public class TestController {
@Autowired
private BookMapping bookMapping;
@RequestMapping(value = "/books",method = RequestMethod.POST)
public Book loadBook(Book book){
bookMapping.addBook(book);
return book;
}
@RequestMapping(value = "/books/{id}",method = RequestMethod.GET)
public Book loadBook(@PathVariable int id){
return bookMapping.loadBook(id);
}
@RequestMapping(value = "/books",method = RequestMethod.GET)
public Book findAllBook(Book book){
bookMapping.findAllBook(book);
return book;
}
@RequestMapping(value = "/books/{id}",method = RequestMethod.PUT)
public Book updataBook(@PathVariable int id,@RequestBody Book book){
bookMapping.updataBook(id,book);
book.setId(id);
return book;
}
@RequestMapping(value = "/books/{id}",method = RequestMethod.DELETE)
public Book updataBook(@PathVariable int id){
return bookMapping.deleteBook(id);
}
}
BookMapping.xml
