Spring Web Security 锁定 Neo4j 嵌入式数据库

Question

继续我的上一期

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，我想我已经找到了这个问题的一般根源，但现在不知道如何解决它。

这是我的 Spring 启动 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;

.....

}

我自动装配了 4 个内部使用 Neo4j 的字段（DAO、存储库等）。当这些字段出现在我的 WebSecurityConfig 中时，Neo4j 在不正常关机后重新启动时挂起。当我删除这些字段时，问题就消失了。

我使用：

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 Neo4j 相关的东西，就会出现这个问题，否则一切正常..

它在事务提交时挂起：

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

有什么问题吗？

我可以确认此问题与以下修复相关 - https://github.com/neo4j/neo4j/commit/c9596af0d990d7dde9a9053799b7295985ae3c05

我应用了这次提交的更改，问题消失了。

所以，现在我正在等待 Neo4j 2.2.4 的发布。

您知道 Neo4j 2.2.4 的计划发布日期吗？
