If you want to develop alfresc extensions you can refer to building and packaging extensions into AMPs using Apache Maven ,add <property name="siteService" ref="SiteService"/> into your spring module context.

If you want to develop client application ,you can use apache commons httpclient to call alfresco site webscript api.

Alternatively, you can also inject the ServiceRegistry into your custom bean XML extension file:

<property name="serviceRegistry" ref="ServiceRegistry"/>

and then get the SiteService locally (or other public services, as needed):

private ServiceRegistry serviceRegistry;

public void setServiceRegistry(ServiceRegistry serviceRegistry) 
{
   this.serviceRegistry = serviceRegistry;
}
public void myMethod()
{
     SiteService siteService = serviceRegistry.getSiteService();
     // ... more here
}

I have already generated AMP using maven and have folder 'context' with 2 xml service-context and webscript-context.

I want the SiteService as property in my java CustomWebScript class, so I have define the CustomWebScript class in webscript-context.xml

If I include in this bean <property name="siteService" ref="SiteService"/>

</bean>

also included private SiteService siteService; as field in my custom Java class.

I receive the following error...

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webscript.custom.get' defined in class path resource [alfresco/module/xxx/context/webscript-context.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException:

Invalid property 'siteService' of bean class [xxx.demoamp.CustomWebScript]: Bean property 'siteService' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

So maybe I don't understand how exactly it works or I miss something...

Thank you in advance for your assistance.

You also need to add the setter, ie.

public void setSiteService(SiteService siteService)

{

this.siteService = siteService;

}

Yes,you need to add setter method in your xxx.demoamp.CustomWebScript class as @Jan Vonka said

After added the setting everything is working fine. Thanks!

Would it work with @Inject or @Autowired annotations above the field or ?

In general I can use the existing webscript -> /alfresco/service/api/sites using HttpConnection and get the json object.

However, I will need the server context(host,port) or something in order not to hard-coded it , could you please advise with that option as well ?

You can try to use org.springframework.beans.factory.annotation.Autowired.

I'm not clear what you mean about the second question.

Re: How to inject SiteService in my custom class?

mbel — Mon, 07 Nov 2016 13:02:26 GMT

Well, My second questions is based on your 2nd suggestion ",you can use apache commons httpclient to call alfresco site webscript api."

For example:

URL loginUrl = new URL("http://localhost:8080/alfresco/service/api/sites");

HttpURLConnection connection = (HttpURLConnection) loginUrl.openConnection();

connection.setRequestMethod("GET");

connection.connect();

InputStream is = connection.getInputStream();

//... and get the json object...

dont want to hard code the http://localhost:8080/ (since it can be changed) I want to get the current server/url context or something...not sure if there is such thing at all.

Or there is some other internal option all webscripts to communicate each other?

I will be really glad if you can answer me to the above questions as I am new with Alfresco and trying to understand how it works.....

Thanks.

You can configure the base part(http://localhost:8080/alfresco/) in a property file in your application,every time when you call webscript api,you can build the full url by concating base part and path part.

I just found that there is SysAdminParams service, which provide the protocol, host, port and alfresco context.

You want to call webscript api in alfresco ??

Re: How to inject SiteService in my custom class?

Jan Vonka is this a safe method as ServiceRegistry is providing lower case service beans?

Re: How to inject SiteService in my custom class?

janv — Tue, 08 Nov 2016 13:12:57 GMT

Angel Borroy Are you sure ? In general, ServiceRegistry returns upper-case public service beans.

Re: How to inject SiteService in my custom class?

angelborroy — Tue, 08 Nov 2016 13:21:55 GMT

Jan Vonka You are right: community-edition/ServiceRegistry.java at master · Alfresco/community-edition · GitHub

My mistake, thanks for the clarification!

Re: How to inject SiteService in my custom class?

kaynezhang — Tue, 08 Nov 2016 13:22:47 GMT

ServiceRegistry do return upper-case public service beans,but but getting some service bean via the ServiceRegistry is not recommended any more.

I have the following code:

String query = "SELECT * FROM cmis:document";

OperationContext oc = session.createOperationContext();

oc.setMaxItemsPerPage(1000000);

resultado = session.query(query.toString(), false, oc);

But I have more than 5 thousand documents and the cmis returns me only a thousand. How do I increase the number of pages that it searches? I believe he is bringing a page with only his maximum (thousand documents).

mbel — Tue, 08 Nov 2016 13:40:41 GMT

well....as an other option. The SiteService is now working and I use the method findSites() to list all sites, however the returned object is different than this one in the /api/sites, so if I want to get the json object from /api/sites, I don't know other option....

If you know, I will be glad if you share it.

Please ask this as a separate question (related to CMIS / OpenCMIS) - thanks.

By default the maximum number of search results that alfresco perform permission checks is 1000

If you want to search more than 1000 ,you should add following settings into your alfresco-global.properties file

system.acl.maxPermissionChecks=5000

But It will reduce performance.
