#### **准备工作** ####

**1、添加配置类**

package com.cj.spring6.tx.config;
    
    import com.alibaba.druid.pool.DruidDataSource;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.jdbc.core.JdbcTemplate;
    import org.springframework.jdbc.datasource.DataSourceTransactionManager;
    import org.springframework.transaction.annotation.EnableTransactionManagement;
    
    import javax.sql.DataSource;
    
    @Configuration
    @ComponentScan("com.cj.spring6")
    @EnableTransactionManagement
    public class SpringConfig {
    
        @Bean
        public DataSource getDataSource() {
            DruidDataSource dataSource = new DruidDataSource();
            dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
            dataSource.setUrl("jdbc:mysql://localhost:3306/spring?characterEncoding=utf8&useSSL=false");
            dataSource.setUsername("root");
            dataSource.setPassword("123456");
            return dataSource;
        }
    
        @Bean(name = "jdbcTemplate")
        public JdbcTemplate getJdbcTemplate(DataSource dataSource) {
            JdbcTemplate jdbcTemplate = new JdbcTemplate();
            jdbcTemplate.setDataSource(dataSource);
            return jdbcTemplate;
        }
    
        @Bean
        public DataSourceTransactionManager getDataSourceTransactionManager(DataSource dataSource) {
            DataSourceTransactionManager dataSourceTransactionManager = new DataSourceTransactionManager();
            dataSourceTransactionManager.setDataSource(dataSource);
            return dataSourceTransactionManager;
        }
    }

最后进行测试：

@Test
        public void testTxAllAnnotation() {
            ApplicationContext applicationContext = new AnnotationConfigApplicationContext(SpringConfig.class);
            BookAllController accountService = applicationContext.getBean("bookAllController", BookAllController.class);
    
            Integer[] bookIds = {1, 2};
            accountService.checkout(bookIds, 1);
        }
