apache – 使用spring引发嵌入式ldap服务器时出现NullPointerException

前端之家收集整理的这篇文章主要介绍了apache – 使用spring引发嵌入式ldap服务器时出现NullPointerException前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

我正在尝试使用以下方法升级Spring嵌入式Ldap服务器:

但我继续得到这个例外:

我正在使用spring 3.0.2并为ldap添加了以下jar:
弹簧安全LDAP的3.0.2.RELEASE.jar
弹簧LDAP的1.3.0.RELEASE-all.jar在
ApacheDS中,全1.5.6.jar
共享LDAP的0.9.15.jar
SLF4J-API-1.5.6.jar
SLF4J-简单1.5.6.jar

请帮忙….

@Zorkus:我不确定您在Apache Directory中遇到了什么样的问题,以及它的根本原因是什么,但如果您只需要一个有效的嵌入式Java LDAP服务器来进行Spring Security的集成测试,那么您可能会想考虑一些替代方案.

我最近开始研究替代品,因为尽管投入了大量的时间和精力,但我无法用Apache Directory实现我想要的东西. (我基本上想将Active Directory实例的模式和用户数据库复制到嵌入式服务器中.)

我发现UnboundID LDAP SDK是一个很好的替代品.与它集成需要比弹簧上下文中的单线程更多的努力(例如< security:ldap-server />),但不多.启动LDAP服务器只需几行代码

InMemoryDirectoryServerConfig config = 
        new InMemoryDirectoryServerConfig("dc=example,dc=com");

// schema config only necessary if the standard 
// schema provided by the library doesn't suit your needs
config.setSchema(Schema.getSchema("your-custom-schema.schema"));

// listener config only necessary if you want to make sure that the
// server listens on port 33389,otherwise a free random port will 
// be picked at runtime - which might be even better for tests btw.
config.setListenerConfigs(
        new InMemoryListenerConfig("myListener",null,33389,null));

InMemoryDirectoryServer ds = new InMemoryDirectoryServer(config);

ds.startListening();

// import your test data from ldif files
ds.importFromLDIF(true,"content.ldif");

您需要的唯一依赖是:

将上面的代码包装在一个可以从Spring上下文中实例化和配置的类中非常容易.
