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. /**

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. }
