Springboot Redis Cache Objects

As soon as you join Spring-boot-starter-data-redis, Springboot automatically recognizes and uses Redis as the cache container, using the following methods

Gradle Join Dependency

    Compile ("Org.springframework.boot:spring-boot-starter-data-redis:${springbootversion}")

Enable caching in Redis configuration

Redis Custom key generation rule

@Bean public    keygenerator wiselykeygenerator () {        return to new Keygenerator () {            @Override public            Object Generate (Object target, Method method, Object ... params) {                StringBuilder sb = new StringBuilder ();                Sb.append (Target.getclass (). GetName ());                Sb.append (":" + method.getname ());                for (Object obj:params) {                    sb.append (":" + obj.tostring ());                }                return sb.tostring ();            }        };    }

Sometimes we need to use redistemplate, so we can configure

@Bean Publicredisconnectionfactory redisconnectionfactory () {return Newjedisconnectionfactory (); } @Bean Publicredistemplate redistemplate (redisconnectionfactory redisconnectionfactory) {redistemplate RedisTemplate=Newredistemplate ();        Redistemplate.setconnectionfactory (redisconnectionfactory); returnredistemplate; } @Bean PublicCacheManager CacheManager (redistemplate redistemplate) {return NewRediscachemanager (redistemplate); }

The other use of spring cache is simple, can be directly crossing network or Baidu example
