找不到AEM6 :：Sling Servlet 404

Question

我已经创建了一个具有表单的登录组件，它具有指向指向siteminder URL https://test1-myuhc.uhc.com/siteminderagent/forms/login-aa.fcc的URL的POST操作

<input type="hidden" name="target" value="/bin/uhc/myuhcauthenticationhandler">

在表单内部，“target”隐藏字段是siteminder转发请求的地方。我在这里设置的目标指向一个Sling Servlet。Servlet在某种身份验证后确实重定向到AEM.The中的相应页面，问题是当我提交组件上的登录按钮时，siteminder将请求转发给https://test1-myuhc.uhc.com/bin/uhc/myuhcauthenticationhandler，这给出了一个404错误。当我将目标设置为存在于/content下的某个实际页面时，它可以正常工作。我能做些什么来解决这个问题。

代码如下：

package com.myuhc.servlets;

Answer 1

为servlet命名，如下所示，或者工作区中的任何唯一搜索，该名称应该是唯一的

@SlingServlet(
        paths={"/bin/myuhc/authenticationhandler"},
        methods = {"POST","GET"},
        metatype=true,
        name = "authentication handler servlet" // give name in servlet and build the project
        )

在干净地安装快照jar之后，再次安装快照jar

转到localhost:/system/ console /components (你可以直接进入felix控制台(系统/控制台/包) -> OSGI -> components)

ctrl+f搜索名称(在我们的示例中是“身份验证处理程序servlet”)，在那里您将找到servlet的路径。检查以下内容

Implementation Class = LoginAuthenticationHandlerServlet 
sling.servlet.paths = [/bin/myuhc/authenticationhandler]

实现类和路径应该与您的servlet相匹配。如果路径不匹配，这意味着正在命中的servlet url属于其他servlet，而这个servlet甚至可能不存在。另外，仔细检查名称在工作区中应该是唯一的。

希望这能有所帮助。
