This Redis ORM solution is currently a temporary one. It is more of an implementation based on "convention." It is simple enough, flexible enough, and you can even directly copy the code without needing to include a jar file.
1、basicly implementation a simple redis orm lib
our goal is implement one redis orm lib, when you change your db data, the redis case sync at once, at the same time keep the code simple and clean.
there are three plan to slove the problem
1、use event driver, the event framework we use spring-event, when database changed, the change method send one event notify the redis listener to sync redis
2、make redis-orm as a annotion, when db method invoked, the orm code at time work,but i don't like to use annotation, it make the code understand complex.
3、use mybatis interceptor, when db update param equals EntityWithId, we can invoke the sync code
4、use inner function, like the mask code :
@Transactional
public User updateUser(User user, function funcRedisOrm) {
// 1. Update MySQL
userMapper.update(user);
// 2. Update Redis
funcRedisOrm();
return use;
}this plan like use the proxy pattern to solve the problem.
summary: the only problem is how to control the invoke time, and the invoke mechanism.
synchronous call ；synchronized call 。
you can use spring manager your serial type, default is json, you can change to protobuf.
@Configuration
public class RedisConfig {
@Bean
public RedisCacheManager redisCacheManager(RedisTemplate<String, String> redisTemplate) {
RedisCacheManager manager = new RedisCacheManager();
manager.setSerializationType(RedisCacheManager.SerializationType.PROTOBUF); // 或JSON
return manager;
}
