ResourceResolverFactory getServiceResourceResolver在AEM 6.1中引发异常 [英] ResourceResolverFactory getServiceResourceResolver throws Exception in AEM 6.1

问题描述

我想向AEM中写入一些数据，下面的代码对我来说在AEM 6.0中工作正常，但在AEM 6.1中却不行，总是抛出如下所示的Login Exception：

I want to write some data to AEM, and the below code works fine for me in AEM 6.0 but not in AEM 6.1 , always throws a Login Exception as follows:

获取服务的CRX用户时的登录异常：'writeService'.org.apache.sling.api.resource.LoginException：无法导出束group.tti.commons-service [395]的用户名，并且子服务writeService

OSGI配置：

我班上的代码：

import javax.jcr.Session;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ResourceResolverFactory;
....
@Reference
private ResourceResolverFactory factory;
private ResourceResolver resourceResolverWriter;
private static Session adminSession;
...
...
Map<String, Object> param = new HashMap<String, Object>();        
    param.put(ResourceResolverFactory.SUBSERVICE, "writeService");
try {
  resourceResolverWriter = factory.getServiceResourceResolver(param);            
  adminSession = resourceResolverWriter.adaptTo(Session.class);
...
} catch (LoginException e) {
...
}

我在AEM 6.1上缺少任何东西吗？

Am i missing anything on AEM 6.1?

推荐答案

在贾斯汀的建议下，我尝试并发现了解决方案。

With Justin's advice, i tried and found the solution. Posting so can be beneficial for others.

目标：在用户登录时将数据/节点写入内容（特别是/ etc / userdata）。

Goal: To write data/nodes to content (specifically to /etc/userdata) when a user logs in.

我们可以通过两种方式实现这一目标（无论哪种方式，用户都必须是系统用户）

We can achieve this in 2 ways (either way, the user needs to be a 'system user')

步骤1：在OSGI配置中使用内置系统用户。在OSGI中，选择 Apache Sling服务用户映射器服务

Step 1: Use in-built system user in OSGI configuration. In OSGI select Apache Sling Service User Mapper Service

group.abc.commons-service：writeService = oauthservice （其中 oauthservice 是系统用户）

步骤2：向该系统用户分配权限来访问内容文件夹。

Step 2: Assign that system user the permissions to access the content folder.

您会在CRX中看到系统用户： / home / users / system

You see the system users in CRX at: /home/users/system

步骤1 ：创建一个新的系统用户。为此
打开 http：// localhost：4502 / crx / explorer / index。 jsp

Step 1: Create a new system user. to do this Open http://localhost:4502/crx/explorer/index.jsp

1. Login as admin 
2. Open 'User Administration
3. Select 'Create System User'
4. Enter "user id"
5. Hit the Green button (you will not se a save button :)`

我已经创建了 abcwriteservice 用户

步骤2：转到权限，然后为用户 abcwriteservice 授予权限以访问您要写入的文件夹。 （在此示例中： / etc / userdata ）

Step 2: Go to Permissions, and for the user abcwriteservice give Permissions to access the folder where you'd like to write. (In this example: /etc/userdata )

第3步：打开OSGI控制台并转到 Apache Sling服务用户映射器服务来定义服务用户映射。

Step 3: Open OSGI console and go to Apache Sling Service User Mapper Service to define the service-user mapping.

示例： group.commons-service：writeService = abcwriteservice

步骤4：在代码中，我添加了额外的参数，例如：

Step 4: In code, i added extra parameter, as:

Map<String, Object> param = new HashMap<String, Object>();
param.put(ResourceResolverFactory.SUBSERVICE, "writeService");

try {
    resourceResolverWriter = factory.getServiceResourceResolver(param);

    if (resourceResolverWriter == null)
        throw new Exception("Could not obtain a CRX User for the Service:'writeService'");

    Node usersRootNode = adminSession.getNode("/etc/userdata/users");
}
