规则的

Question

我们正在运行2.4版

由于我们有很多与 IgniteClientDisconnectedException 相关的问题，我正在编写一个手动分段解析器（通过在客户端重新连接禁用设置为 true 的情况下禁用客户端重新连接），它将检测这种情况（使用定期运行的简单缓存查询）

我在缓存访问方面遇到了其他问题，如本文所述解决了这些问题

但问题是，每当我尝试使用spring事务注释方法时，它都无法创建一个带有IllegalStateException的事务，其中提到网格处于无效状态。

我怀疑它再次与我之前遇到的过时引用（上面引用）相同的问题，并且可能需要通过在 SpringTransactionManager 中更新内核引用在代码中处理它。我正在尝试该修复程序

同时，如果有人有更简单/更快的解决方法/建议，请分享。

下面是例外，

Answer 1

我之前提到的解决方法奏效了。对于可能面临此问题的其他人，修复方法包括在重新连接后更新SpringTransactionManager中的ignite内核引用。

下面是所需的代码更改，

在SpringTransactionManager.java中，

/**
 * @author mlekshma
 * 
 * @param ignite
 */
protected void setResourceFactory(final Ignite ignite) {
    this.ignite = ignite;
}

我使用SpringTransactionManager的匿名内部类来破解注入，因为2.4中存在Ignite-Spring集成问题（这里有更多信息），

/**
 * @author mlekshma
 *
 */
@Configuration
@EnableScheduling
@ComponentScan("com.***.***")
@EnableIgniteRepositories(basePackages={"com.***.***"})
@ImportResource("classpath:ignite-client-conf.xml")
@PropertySource("classpath:ignite-client.properties")
@EnableTransactionManagement
public class IgniteClientConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(IgniteClientConfig.class);

    public IgniteClientConfig() {
    }

    /**
     * @return
     */
    @Bean
    @DependsOn("igniteInstance")
    @Primary
    @Lazy
    public PlatformTransactionManager transactionManager() {
        final SpringTransactionManager springTransactionManager = new SpringTransactionManager() {

            private boolean isInitialized = false;

            @Override 
            public void afterPropertiesSet() throws Exception {
                if (isInitialized) {
                    if(((IgniteKernal) getResourceFactory()).context().gateway().getState() == GridKernalState.STOPPED) {
                        IgniteKernal igniteKernal = (IgniteKernal) Ignition.ignite(getIgniteInstanceName());
                        if(igniteKernal != null) {
                            setResourceFactory(igniteKernal);
                        }
                    }
                }
            }

            /**
             * @param event
             */
            @EventListener
            public void handleContextRefresh(final ContextRefreshedEvent event) throws Exception {
                LOGGER.info("Setting up tx support..");
                super.afterPropertiesSet();
                isInitialized = true;
            }
        };
        // Use default grid client instance created..
        springTransactionManager.setTransactionConcurrency(TransactionConcurrency.PESSIMISTIC);
        return springTransactionManager;
    }

}

Answer 2

在2.5版本（https://issues.apache.org/jira/browse/IGNITE-2766）中，重新连接后关闭缓存是固定的。

据我所知，您想创建一个新的点燃实例并为SpringTransactionManager使用一个。我认为这不是正确的方式，因为有缓存实例，例如在IgniteRepositoryImpl#缓存中，也需要重新初始化。

我确实建议使用IgniteClientDisconnectedException#reconnectFuture（）方法，该方法返回重新连接发生时将完成的未来。因此，您可以阻止该客户端，并等待将来的问题得到解决，并且该客户端处于活动状态。例如：

public void checkAndReconnect(){
    try{
        // make ignite query
    }catch(IgniteClientDisconnectedException ex){
       ex.reconnectFuture().get();
    }
}

希望它有助于解决连接问题。
