A Simple Cache Library both local and redis remote cache

<dependency>
    <groupId>wiki.chiu.megalith</groupId>
    <artifactId>cache-spring-boot-starter</artifactId>
    <version>3.4.2</version>
</dependency>

or

implementation("wiki.chiu.megalith:cache-spring-boot-starter:3.4.2")

use:

import java.lang.reflect.Method;
import java.util.HashSet;

@RestController
public class MyClass {
    
    @Autowired
    private CacheEvictHandler cacheEvictHandler;

    //use cache:
    @GetMapping("/test")
    @Cache(prefix = "keyPrefix")
    public String test() {
        return "this is a value";
    }

    //evict cache:
    @GetMapping("/evict")
    public String evict() {
        Method method = MyClass.class.getMethod("test");
        HashSet<String> keys = CommonCacheKeyGenerator.generateKey(method);
        cacheEvictHandler.evictCache(keys);
    }
}

The rule of the generation of key can be find in class CommonCacheKeyGenerator::generateKey

It can be auto upgraded to a stable queue(if you used rabbitmq) via config and rabbitmq dependencies(default setting is redis):
