【分布式缓存】springboot整合jetcache使用详解

import com.alicp.jetcache.Cache;
import com.alicp.jetcache.CacheBuilder;
import com.alicp.jetcache.embedded.EmbeddedCacheBuilder;
import com.alicp.jetcache.anno.CacheConsts;
import com.alicp.jetcache.anno.config.EnableCreateCacheAnnotation;
import com.alicp.jetcache.anno.config.EnableMethodCache;
import com.alicp.jetcache.anno.support.SpringConfigProvider;
import com.alicp.jetcache.embedded.EmbeddedCacheConfig;
import com.alicp.jetcache.support.FastjsonKeyConvertor;
import com.alicp.jetcache.support.JavaValueDecoder;
import com.alicp.jetcache.support.JavaValueEncoder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
@EnableMethodCache(basePackages = "com.yourpackage.service")
@EnableCreateCacheAnnotation
public class CacheConfig {
 
    @Bean
    public SpringConfigProvider springConfigProvider() {
        return new SpringConfigProvider();
    }
 
    @Bean
    public CacheBuilder<Object, Object> cacheBuilder() {
        EmbeddedCacheBuilder embeddedCacheBuilder = EmbeddedCacheBuilder.createEmbeddedCacheBuilder()
                .keyConvertor(FastjsonKeyConvertor.INSTANCE)
                .valueEncoder(JavaValueEncoder.INSTANCE)
                .valueDecoder(JavaValueDecoder.INSTANCE)
                .config(config());
        return embeddedCacheBuilder;
    }
 
    private EmbeddedCacheConfig config() {
        EmbeddedCacheConfig cacheConfig = new EmbeddedCacheConfig();
        cacheConfig.setName(CacheConsts.DEFAULT_CACHE_NAME);
        // 设置其他配置参数
        return cacheConfig;
    }
 
    @Bean
    public Cache<Object, Object> defaultCache(CacheBuilder<Object, Object> cacheBuilder) {
        return cacheBuilder.buildCache();
    }
}

这个配置类定义了一个名为defaultCache的缓存Bean，它使用了FastjsonKeyConvertor进行序列化，JavaValueEncoder和JavaValueDecoder进行值的编码和解码。同时，它也启用了注解方式的缓存，这意味着在服务层的方法上使用@CreateCache和@RefreshCache注解可以创建和刷新缓存。这个配置类也展示了如何配置默认缓存的基本参数。
