Liferay7 BPM门户开发之34: liferay7对外服务类生成(RestService Get Url)

在liferay7中开发不依赖Service Builder的对外服务类,非常简洁,只需要2点注解:

  • 在类的前部定义:

  @ApplicationPath("/PathXXX")

  • 方法前定义:

  @GET
  @Path("/ActionXXX")
  @Produces("text/plain")

例子:得到注册用户

import com.liferay.portal.kernel.model.User;import com.liferay.portal.kernel.service.UserLocalService;import java.util.Collections;import java.util.Set;import javax.ws.rs.ApplicationPath;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.Produces;import javax.ws.rs.core.Application;import org.osgi.service.component.annotations.Component;import org.osgi.service.component.annotations.Reference;@ApplicationPath("/allUsers")@Component(    immediate = true, property = {"jaxrs.application=true"},    service = Application.class)public class UsersRestService extends Application {    @Override    public Set<Object> getSingletons() {        return Collections.singleton((Object)this);    }    @GET    @Path("/list")    @Produces("text/plain")    public String getAllUsers() {        StringBuilder result = new StringBuilder();        for (User user : _userLocalService.getUsers(-1, -1)) {            result.append(user.getFullName()).append(",\n");        }        return result.toString();    }    @Reference    public void setUserLocalService(UserLocalService userLocalService) {        _userLocalService = userLocalService;    }    private UserLocalService _userLocalService;}

 

osgi语法真是简洁。
