20_Spring_零XML事务控制

创建配置类

1. package com.msb.config;
2. import com.alibaba.druid.pool.DruidDataSource;
3. import org.springframework.beans.factory.annotation.Value;
4. import org.springframework.context.annotation.Bean;
5. import org.springframework.context.annotation.ComponentScan;
6. import org.springframework.context.annotation.Configuration;
7. import org.springframework.context.annotation.PropertySource;
8. import org.springframework.jdbc.core.JdbcTemplate;
9. import org.springframework.jdbc.datasource.DataSourceTransactionManager;
10. import org.springframework.transaction.PlatformTransactionManager;
11. import
    org.springframework.transaction.annotation.EnableTransactionManagement;
12. import javax.sql.DataSource;
13. /**

16. */
17. @Configuration // 配置类标志注解
18. @ComponentScan(basePackages = "com.msb") // spring包扫描
19. @PropertySource("classpath:jdbc.properties") // 读取属性配置文件
20. @EnableTransactionManagement // 开启事务注解
21. public class SpringConfig {

22. @Value("${jdbc_driver}")
    

23. private String driver;
    

24. @Value("${jdbc_url}")
    

25. private String url;
    

26. @Value("${jdbc_username}")
    

27. private String username;
    

28. @Value("${jdbc_password}")
    

29. private String password;
    

30. /*创建数据库连接池*/
    

31. @Bean
    

32. public DruidDataSource getDruidDataSource(){
    

33.     DruidDataSource dataSource=new DruidDataSource();
    

34.     dataSource.setDriverClassName(driver);
    

35.     dataSource.setUrl(url);
    

36.     dataSource.setUsername(username);
    

37.     dataSource.setPassword(password);
    

38.     return dataSource;
    

39. }
    

40. /*创建JdbcTemplate对象*/
    

41. @Bean
    

42. public JdbcTemplate getJdbcTemplate(DataSource dataSource){
    

43.     JdbcTemplate jdbcTemplate=new JdbcTemplate();
    

44.     jdbcTemplate.setDataSource(dataSource);
    

45.     return jdbcTemplate;
    

46. }
    

47. /*创建事务管理器*/
    

48. @Bean
    

49. public PlatformTransactionManager
    

    getPlatformTransactionManager(DataSource dataSource){

50.     DataSourceTransactionManager transactionManager =new
    

    DataSourceTransactionManager();

51.     transactionManager.setDataSource(dataSource);
    

52.     return transactionManager;
    

53. }
    

54. }

测试代码

1. @Test()

2.  public void testTransaction3(){
   

3.      ApplicationContext context =new
   

   AnnotationConfigApplicationContext(SpringConfig.class);

4.      AccountService accountService =
   

   context.getBean(AccountService.class);

5.      int rows = accountService.transMoney(1, 2, 100);
   

6.      System.out.println(rows);
   

7.  }
