I am currently working on a project which is using Redis mainly for caching purposes, I am using Oracle as the main database and Spring Data JPA to handle the database layer in my project. I need to know how to use @Transactional annotation support to handle transactions in Redis. I have already referred to lots of tutorials and documentation regarding this scenario. In most of those tutorials, there is always the same set of source codes available. But still, I didn't have a clear idea about the implementation. Because in my application there is already a data source available which I configured through property file. (Oracle database) So I doubt the implementation of the dataSource bean. And I couldn't understand the usage of transactionManager bean too. How should I implement this properly please give a detailed explanation.
Source code which I found on the internet.
@Configuration@EnableTransactionManagement // 1public class RedisConfig { @Bean public StringRedisTemplate stringRedisTemplate(LettuceConnectionFactory redisConnectionFactory) { // Configure redisTemplate StringRedisTemplate stringRedisTemplate = new StringRedisTemplate(); stringRedisTemplate.setConnectionFactory(redisConnectionFactory); / / Open transaction support stringRedisTemplate.setEnableTransactionSupport(true); // 2 return stringRedisTemplate; } @Bean public PlatformTransactionManager transactionManager() throws SQLException { return new DataSourceTransactionManager(dataSource()); // 3 } @Bean public DataSource dataSource() throws SQLException { // ... }}
