spring boot集成mybatis+事务控制

一下代码为DEMO演示，采用注解的方式完成Spring boot和Mybatis的集成，并进行事物的控制

数据源的配置:

spring.datasource.url=jdbc:mysql://localhost:3306/book
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

 

依赖包:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.0.0</version>
</dependency>

 

Mapper：

@Configuration
public interface BookMapper {
    
    @Update("update books set publicsher =#{publicsher} where bookid = #{id}")
    public int update(@Param("publicsher")String publicsher,@Param("id")int id);
}

 

Service：

@Service
public class BookServiceImpl implements BookService {
    
    @Autowired
    private BookMapper bookMapper;
    
    @Transactional
    public void update(String publicsher , int bookId) {
        bookMapper.update(publicsher,bookId);
    }

}

 

Controller:

@RestController
public class BookController {
    
    @Autowired
    private BookService bookService;
    
    @RequestMapping("/updataBook")
    public String updataBook(String name,int id) {
        bookService.update(name,id);
        return "updata Success";
    }
    
}

 

App：

@ComponentScan(basePackages = { "com.szzt.controller" , "com.szzt.service","com.szzt.exceptionHandler"})
@MapperScan(basePackages="com.szzt.mapper")
@EnableAutoConfiguration
public class App {
    
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
    
}
