2. Create a pom.xml in cloudstack/plugins/api/timeofday. Make sure your "parent" relative path points back to plugins/pom.xml, otherwise it won't build. The main entries that matter are the artifactId (cloud-plugin-timeofday), as well as the dependencies.

6. Create an interface that extends from PluggableService
| Code Block | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| ||||||||||
package com.cloud.test;
import com.cloud.utils.component.PluggableService;
public interface TimeOfDayManager extends PluggableService { }
|
7. Create an implementation of your newly created interface, overriding the getCommands method, and populating it with the classes of each command you want to expose.

|---|---|---|---|---|---|---|---|---|---|---|
| ||||||||||
package com.cloud.test;
import com.cloud.utils.component.PluggableService;
import java.util.List;
import java.util.ArrayList;
import org.apache.log4j.Logger;
import com.cloud.test.GetTimeOfDayCmd;
import javax.annotation.PostConstruct;
import org.springframework.stereotype.Component;
import javax.ejb.Local;
@Component
@Local(value = { TimeOfDayManager.class })
public class TimeOfDayManagerImpl implements TimeOfDayManager {
private static final Logger s_logger = Logger.getLogger(TimeOfDayManagerImpl.class);
public TimeOfDayManagerImpl() {
super();
}
@Override
public List<Class<?>> getCommands() {
List<Class<?>> cmdList = new ArrayList<Class<?>>();
cmdList.add(GetTimeOfDayCmd.class);
return cmdList;
}
}
|
8. Write a command class that implements the correct annotations for a command:: (Note: (1) by using authorized annotation, we can enabled this API by default for a given set of role types, (2) by using the validations annotation on @Parameter field we can perform ApiArgValidator.NotNullOrEmpty checks on string types and ApiArgValidator.PositiveNumber on number types such as short, int, long.)

9. Write a Response class for the command:

package com.cloud.test;
import org.apache.cloudstack.api.ApiConstants;
import com.cloud.serializer.Param;
import com.google.gson.annotations.SerializedName;
import org.apache.cloudstack.api.BaseResponse;
import java.util.Date;
import java.text.SimpleDateFormat;
@SuppressWarnings("unused")
public class GetTimeOfDayCmdResponse extends BaseResponse {
@SerializedName(ApiConstants.IS_ASYNC) @Param(description="true if api is asynchronous")
private Boolean isAsync;
@SerializedName("timeOfDay") @Param(description="The time of day from CloudStack")
private String timeOfDay;
@SerializedName("exampleEcho") @Param(description="An upper cased string")
private String exampleEcho;
public GetTimeOfDayCmdResponse(){
this.isAsync = false;
SimpleDateFormat dateformatYYYYMMDD = new SimpleDateFormat("yyyyMMdd hh:mm:ss");
this.setTimeOfDay( (new StringBuilder( dateformatYYYYMMDD.format( new Date() ) )).toString() );
}
public void setAsync(Boolean isAsync) {
this.isAsync = isAsync;
}
public boolean getAsync() {
return isAsync;
}
public void setTimeOfDay(String timeOfDay) {
this.timeOfDay = timeOfDay;
}
public void setExampleEcho(String exampleEcho) {
this.exampleEcho = exampleEcho.toUpperCase();
}
}

11. Update 11. For CloudStack version 4.8.x and below update client/tomcatconf/commands.properties.in, and add the command name (for the example this would be getTimeOfDay as stated in the @APICommand annotation). For CloudStack 4.9.x and above, the commands.properties.in way has been deprecated and API authors are encouraged to enable their API by default using authorized annotation as in the example above which can be used to enable the API for a given set of user role types.
12. Along with this you need to add your plugin as a dependency to client/pom.xml. You will see examples within the pom, you will require your plugins artifact ID.
