Question

继续我之前的问题Neo4j Embedded database hangs after abnormal application termination

我注意到，如果我在终止应用程序之前使用graphDatabaseService.shutdown();方法，一切正常。否则在重新启动后，我的应用程序会挂起数据库操作。

经过几个小时的调查后，我想，我已经找到了这个问题的一般来源，但现在还不知道如何修复它。

这是我的Spring Boot 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内存在这些字段时，Neo4j在不干净关闭后重启。当我删除这些字段时，问题就会消失。

我用：

OS: Windows 8.1
jdk1.8.0_51
Spring 4.1.7.RELEASE
Spring Boot 1.2.5.RELEASE
Spring Security 3.2.7.RELEASE 
neo4j version 2.2.3
lucene version 3.6.2
spring-data-neo4j version 3.4.0.M1

如果WebSecurityConfig引用了与Neo4j相关的内容，则会出现此问题，否则一切正常..

它挂起在事务提交上：

2015-07-29 16:47:51 [main] DEBUG o.s.t.jta.JtaTransactionManager - Initiating transaction commit

有什么不对？

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？
