SSM整合（接口测试）

src/main/test 下创建 com.xxx.service.BookServiceTest

package com.xxx.service;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SpringConfig. class)
public class BookServiceTest {

    @Autowired
    private BookService bookService;

    @Test
    public void testGetById(){
        Book book = bookService.getById(1);
        System.out.println(book);
    }

    @Test
    public void testGetAll(){
        List<Book> all = bookService.getAll();
        System.out.println(all);
    }
}

添加事务管理

SpringConfig.java

package com.xxx.config;

@Configuration
@Component({"com.xxx..service"})
@PropertySource("jdbc.properties")
@Import({JdbcConfig.class, MyBatisConfig.class})
@EnableTransactionManagement
public class SpringConfig {

}

JdbcConfig.java

package com.xxx.config;

public class JdbcConfig {

    @Value("${jdbc.drive}")
    private String driver;
    @Value("${jdbc.url}")
    private String url;
    @Value("${jdbc.username}")
    private String username;
    @Value("${jdbc.password}")
    private String password;

    @Bean
    public DataSource dataSource(){
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName(driver);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        return dataSource;
    }

    @Bean
    public PlatformTransactionManager transactionManager(DataSource dataSource){
        DataSourceTransactionManager ds = new DataSourceTransactionManager();
        ds.setDataSource(dataSource);
    }
}

BookService.java

package com.xxx.service;

@Transactionl
public interface BookService {

    public boolean save(Book book);

    public boolean update(Book book);

    public boolean delete(Integer id);

    public Book getById(Integer id);

    public List<Book> getAll();
}
