通常我不提供点火配置。我只是这样做：
this.ignite = Ignition.getOrStart(new IgniteConfiguration());
并对点燃执行一些操作：
this.ignite.getOrCreateCache(Identifiers.BRAND_IGNITE_ITEM_CACHE).removeAll();
this.ignite.getOrCreateCache(Identifiers.BRAND_IGNITE_ITEM_CACHE).putAll(map);
工作正常。出于测试目的，我现在想要使用ignite创建一个内存数据库，以便拥有一个数据库，我可以从中将项目加载到我的ignite缓存中。所以我创建了一个jdbc连接：
public class DefaultConnection {
private static Connection connection = null;
public static Connection getConnection(String driverName, String host, String user, String password) throws SQLException {
if (connection != null) {
return connection;
} else {
try {
Class.forName(driverName);
} catch (ClassNotFoundException e) {
log.severe(e.getMessage());
return null;
}
if (user == null || password == null) {
return DriverManager.getConnection(host);
}
return DriverManager.getConnection(host, user, password);
}
}
}
this.DRIVER_NAME = "org.apache.ignite.IgniteJdbcThinDriver";
this.HOST = "jdbc:ignite:thin://127.0.0.1/";
this.connection = DefaultConnection.getConnection(DRIVER_NAME, HOST, null, null);
... // create tables and insert some data
注意我还没有使用.loadCache(null)上的ignite.getOrCreateCache("MyCache")函数将数据从数据库加载到缓存中。我刚刚创建了一些包含一些数据的表。
当我现在想要在空缓存上执行操作时，就像一个简单的get：
this.ignite = Ignition.getOrStart(new IgniteConfiguration());
this.ignite.getOrCreateCache("MyCache").get("123456");
我收到以下错误：
reactor.core.Exceptions$ErrorCallbackNotImplemented: java.lang.IllegalStateException: Grid is in invalid state to perform this operation. It either not started yet or has already being or have stopped [igniteInstanceName=null, state=STOPPED]

如果我没有创建一个jdbc连接来点燃一切正常。
“MyCache”的缓存配置示例：
private CacheConfiguration<String, MyItem> getCacheConfiguration() {
final CacheConfiguration<String, MyItem> cacheConfiguration = new CacheConfiguration<>("MyCache");
cacheConfiguration.setName("MyCache");
cacheConfiguration.setIndexedTypes(String.class, MyItem.class);
cacheConfiguration.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
cacheConfiguration.setCacheStoreFactory(FactoryBuilder.factoryOf(MyItemCacheStore.class.getName()));
cacheConfiguration.setReadThrough(true);
cacheConfiguration.setWriteThrough(true);
cacheConfiguration.setCopyOnRead(false);
cacheConfiguration.setCacheMode(CacheMode.PARTITIONED);
cacheConfiguration.setOnheapCacheEnabled(true);
cacheConfiguration.setEvictionPolicy(new LruEvictionPolicy());
return cacheConfiguration;
}
当有一个打开的jdbc连接点燃时，为什么isnt点燃能够构建网格？
修改
一些额外的信息：我只需要jdbc连接进行单元测试。此异常只出现在使用gradlew test如果我运行单元测试“正常”方式一切正常

注意：仅在运行gradlew test时以及使用@ActiveProfiles("test")注释服务测试类时才会显示异常。在其他情况下
