使用HazelCast实现Spring Boot自定义缓存解析器和缓存管理器

要使用Hazelcast实现Spring Boot自定义缓存解析器和缓存管理器，你需要按照以下步骤操作：

步骤1：添加依赖 首先，将Hazelcast的Spring Boot Starter依赖添加到你的项目中。在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>com.hazelcast</groupId>
    <artifactId>hazelcast-spring</artifactId>
    <version>4.2.2</version>
</dependency>

步骤2：创建Hazelcast配置 创建一个Hazelcast的配置类，用于配置Hazelcast实例。例如，创建一个名为HazelcastConfig的类，如下所示：

import com.hazelcast.config.Config;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableCaching
public class HazelcastConfig {

    @Bean
    public Config hazelcastConfig() {
        Config config = new Config();
        // 添加其他配置项，如集群配置等
        return config;
    }
}

步骤3：实现自定义缓存解析器 创建一个实现Spring的CacheResolver接口的自定义缓存解析器。这个解析器将用于解析缓存注解，并返回一个HazelcastCache对象。例如，创建一个名为HazelcastCacheResolver的类，如下所示：

import com.hazelcast.core.HazelcastInstance;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.Cache;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CacheConfig;
import org.springframework.cache.interceptor.CacheOperationInvocationContext;
import org.springframework.cache.interceptor.CacheResolver;
import org.springframework.stereotype.Component;

import java.util.Collection;
import java.util.Collections;

@Component
public class HazelcastCacheResolver implements CacheResolver {

    @Autowired
    private HazelcastInstance hazelcastInstance;

    @Autowired
    private CacheManager cacheManager;

    @Override
    public Collection<? extends Cache> resolveCaches(CacheOperationInvocationContext<?> context) {
        CacheConfig cacheConfig = context.getMethod().getAnnotation(CacheConfig.class);
        String cacheName = cacheConfig.cacheNames()[0];
        Cache cache = cacheManager.getCache(cacheName);
        if (cache == null) {
            cache = createCache(cacheName);
            cacheManager.getCacheNames().add(cacheName);
        }
        return Collections.singleton(cache);
    }

    private Cache createCache(String cacheName) {
        return new HazelcastCache(cacheName, hazelcastInstance);
    }
}

步骤4：实现自定义缓存管理器 创建一个实现Spring的CacheManager接口的自定义缓存管理器。这个管理器将用于管理HazelcastCache对象。例如，创建一个名为HazelcastCacheManager的类，如下所示：

import com.hazelcast.core.HazelcastInstance;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.Cache;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Configuration;

import java.util.Collection;
import java.util.Collections;
import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.ConcurrentMap;

@Configuration
@EnableCaching
public class HazelcastCacheManager implements CacheManager {

    private final ConcurrentMap<String, Cache> caches = new ConcurrentHashMap<>();

    @Autowired
    private HazelcastInstance hazelcastInstance;

    @Override
    public Cache getCache(String name) {
        Cache cache = caches.get(name);
        if (cache == null) {
            cache = createCache(name);
            caches.put(name, cache);
        }
        return cache;
    }

    @Override
    public Collection<String> getCacheNames() {
        return Collections.unmodifiableSet(caches.keySet());
    }

    private Cache createCache(String name) {
        return new HazelcastCache(name, hazelcastInstance);
    }
}

步骤5：实现自定义Hazelcast缓存 创建一个实现Spring的Cache接口的自定义Hazelcast缓存。这个缓存将使用Hazelcast实例来存储缓存数据。例如，创建一个名为HazelcastCache的类，如下所示：

import com.hazelcast.core.HazelcastInstance;
import com.hazelcast.core.IMap;
import org.springframework.cache.Cache;
import org.springframework.cache.support.SimpleValueWrapper;

import java.util.concurrent
