Spring LDAP error code 32 - No Such Object]; remaining name '/'"

问题

以下是翻译好的内容：

我是LDAP的新手，我尝试使用Spring运行一个CRUD示例。首先，我学习并运行了一个使用[此][1]指南的示例，这是一次成功的尝试。需要注意的是，此指南适用于嵌入式LDAP（不是本地LDAP），而我是为本地LDAP执行的。使用[此][2]指南，我尝试进行一个CRUD项目。当我使用Postman从http://localhost:8080/retrieve-users获取结果时，我收到以下错误消息：

    > "status": 500, "error": "Internal Server Error", "message": "[LDAP:
    > error code 32 - No Such Object]; nested exception is
    > javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such
    > Object]; remaining name '/'", "path": "/retrieve-users"
而在IntelliJ控制台中的错误消息是：

    ERROR 18652 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : 在路径为[]的上下文中，servlet [dispatcherServlet] 的服务（Servlet.service()）抛出异常[请求处理失败；嵌套异常为org.springframework.ldap.NameNotFoundException: [LDAP: error code 32 - No Such Object]; nested exception is javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such Object]; remaining name '/']

    javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such Object]

    	...
您可以在Internet上找到类似的错误，其中所有错误都被告知找不到所提到的对象。但我的问题是，此处提到的对象是`remaining name '/'`，我无法确定缺少哪个对象。

英文:

I'm new to LDAP and I try to run a CRUD example with Spring. First I learned and run an example using this guide and it was a successful try. It should be mentioned that this guide was for embedded LDAP (not local LDAP) and I do it for local LDAP. Using this guide I try to do a CRUD project. When I using postman for getting results from http://localhost:8080/retrieve-users I get this error:

> "status": 500, "error": "Internal Server Error", "message": "[LDAP:
> error code 32 - No Such Object]; nested exception is
> javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such
> Object]; remaining name '/'", "path": "/retrieve-users"

and the error in IntelliJ console is:

ERROR 18652 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.ldap.NameNotFoundException: [LDAP: error code 32 - No Such Object]; nested exception is javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such Object]; remaining name '/'] with root cause

I found similar errors in the internet and all of them was told that an mentioned object don't exist. But my problem is that the mentioned object here is remaining name '/' and I can not find out which object not exist.

答案1

得分: 2

你在模型上没有正确设置对象。你必须在@Entry注解中进行指定。类似于这样：

@Entry(base="ou=users", objectClasses = {
        "top",
        "inetOrgPerson", "person", "organizationalPerson",
        "simpleSecurityObject"})

这篇教程帮助我设置了Spring Data LDAP：

https://dzone.com/articles/spring-ldap

英文:

You haven't set the object right on your model. You have to specify it in the @Entry annotation. Something like this:

@Entry(base="ou=users", objectClasses = {
"top",
"inetOrgPerson", "person", "organizationalPerson",
"simpleSecurityObject"})

This tutorial helped me set up spring data ldap:
