不幸的是，我无法从缓存中检索密钥集，因为我收到以下错误：
ISPN000287：未经授权的访问：主题“null”缺少“ADMIN”权限
这很奇怪；因为在这个示例代码中，如果它不存在，我可以创建一个缓存（当然，如果你想创建一个缓存，你需要是管理员）但是我不能只检索该缓存的键集。
我是在做一些错误还是实际上存在错误？
重现步骤：
- 将附加的配置（infinispan.xml）放入：<SERVER_ROOT>/server/conf/infinispan.xml

运行服务器（ bin/server.sh ）
运行附带的 JAVA 程序
import java.io.IOException;
import java.util.Properties;
import java.util.Set;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import org.apache.logging.log4j.LogManager;

import org.infinispan.commons.api.CacheContainerAdmin;
public class InfinispanSample {
public static void main(String[] args) {
// Create a configuration for a locally-running server
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.addServer().host("127.0.0.1").port(ConfigurationProperties.DEFAULT_HOTROD_PORT);
// Workaround for docker 4 mac
builder.clientIntelligence(ClientIntelligence.BASIC);
//Configure the security properties
builder.security().authentication()
.username("adminuser")
.password("12345678")
.saslMechanism("DIGEST-MD5")
.realm("default")
.serverName("datagridAuth");
// Connect to the server
RemoteCacheManager cacheManager = new RemoteCacheManager(builder.build());
// Create test cache, if such does not exist
cacheManager.administration().withFlags(CacheContainerAdmin.AdminFlag.VOLATILE).getOrCreateCache("test",
DefaultTemplate.DIST_SYNC);
// Obtain the remote cache
RemoteCache<String, String> cache = cacheManager.getCache("test");
/// Store a value
cache.put("key", "value");
cache.put("key2", "XX");
// Retrieve the value and print it out
System.out.printf("key = %s\n", cache.get("key"));
System.out.printf("key2 = %s\n", cache.get("key2"));
Set<String> remoteCacheKeySet = cache.keySet();
remoteCacheKeySet.stream().forEach(item -> {
String val = cache.get(item);
System.out.printf("key = " + item + " = " + val);
});
// Stop the cache manager and release all resources
cacheManager.stop();
}
}
当我执行程序时，我看到它正确检索了 key1 和 key2 ，但是在执行 keySet 操作时出现了 ISPN000287 错误。
在这里我发布一个摘录
