我将基于Neo4j嵌入式数据库公开我的第一个应用程序并遇到严重阻塞问题 -
这是我之前关于数据库删除的问题，我在这里遇到了这个问题Effectively clear Neo4j database
我用：
OS: Windows 8.1
jdk1.8.0_51
neo4j version 2.2.3
lucene version 3.6.2
spring-data-neo4j version 3.4.0.M1
我注意到如果我在终止我的应用程序之前使用graphDatabaseService.shutdown();方法，一切正常。否则数据库被销毁（不仅是我的应用程序，但是当我尝试加载我的时候，甚至Neo4j服务器也会挂起这个损坏的数据库带有Neo4j Web界面的嵌入式数据库）。
有什么方法可以让Neo4j Embedded数据库更具容错能力？在生产环境中出现第一个错误（例如停电事件）后，我将丢失所有数据。
我在这个问题上花了几天时间，但仍然没有想法如何继续它。请帮忙。

在删除操作期间，应用程序会挂起tx.close();行：
public class Neo4jUtils {
final static Logger logger = LoggerFactory.getLogger(Neo4jUtils.class);
private static final int BATCH_SIZE = 10;
public static void cleanDb(Neo4jTemplate template) {
logger.info("Cleaning database");
long deletedNodesCount = 0;
do {
GraphDatabaseService graphDatabaseService = template.getGraphDatabaseService();
Transaction tx = graphDatabaseService.beginTx();
try {
Result<Map<String, Object>> result = template.query("MATCH (n) WITH n LIMIT " + BATCH_SIZE + " OPTIONAL MATCH (n)-[r]-() DELETE n, r RETURN count(n) as count", null);
deletedNodesCount = (long) result.single().get("count");
tx.success();
logger.info("Deleted " + deletedNodesCount + " nodes...");
} catch (Throwable th) {
logger.error("Error while deleting database", th);
throw th;
} finally {
tx.close();
}
} while (deletedNodesCount > 0);
}
}
已更新
我找到了这个问题的一般来源，但现在不知道如何修复它。
这是我的WebSecurityConfig：
@Configuration
@EnableWebSecurity
@EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private SocialAuthenticationSuccessHandler socialAuthenticationSuccessHandler;
@Autowired
private TokenAuthenticationService tokenAuthenticationService;
@Autowired
private TokenAuthenticationFilter tokenAuthenticationFilter;
@Autowired
private DBUserDetailsService userDetailsService;
.....
}
我自动安装了4个内部使用Neo4j的字段（DAO，存储库等）。当我的WebSecurityConfig中存在这些字段时，Neo4j在不干净关闭后挂起重启。当我评论这些字段时，问题就会消失。
有什么不对？
答案 0 :(得分：2)
Neo4j Enterprise允许您在群集中运行多个Neo4j实例，为您提供高可用性和扩展读取。为了在n失败的同时生存，您需要2n+1个实例。
如果是不干净的关闭，预期的行为是下次启动时的自动恢复操作（可能需要一些时间）。在过去的几年里，在不干净的关闭之后，我从未经历过处于不可恢复状态的Neo4j。
对于嵌入式使用案例，请务必在JVM shutdown hook中致电gdb.shutdown()。

我可以确认此问题与以下修复有关 - https://github.com/neo4j/neo4j/commit/c9596af0d990d7dde9a9053799b7295985ae3c05
我已应用此提交中的更改，问题就消失了。
所以，现在我正在等待Neo4j 2.2.4发布。
您知道Neo4j 2.2.4的计划发布日期吗？
