Spring Boot的事务处理

spring boot大大简化了之前java项目需要在配置xml里设置很多繁琐的内容。
设置数据源

 @Bean(name = "masterDataSource")
    @Primary
    public DataSource druidDataSource() {
        DruidDataSource druidDataSource = new DruidDataSource();
        druidDataSource.setDriverClassName(driver);
        druidDataSource.setUrl(url);
        druidDataSource.setUsername(username);
        druidDataSource.setPassword(password);
        druidDataSource.setInitialSize(initialSize);
        druidDataSource.setMinIdle(minIdle);
        druidDataSource.setMaxActive(maxActive);
        druidDataSource.setMaxWait(maxWait);
        druidDataSource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
        druidDataSource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
        druidDataSource.setValidationQuery(validationQuery);
        druidDataSource.setTestWhileIdle(testWhileIdle);
        druidDataSource.setTestOnBorrow(testOnBorrow);
        druidDataSource.setTestOnReturn(testOnReturn);
        druidDataSource.setPoolPreparedStatements(poolPreparedStatements);
        druidDataSource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);

        try {
            druidDataSource.setFilters("stat");
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return druidDataSource;
    }

  @Bean(name = "masterTransactionManager")
    @Primary
    public PlatformTransactionManager transactionManager() {
        return new DataSourceTransactionManager(druidDataSource());
    }

只需要在
