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

本文主要是介绍Liferay7 BPM门户开发之34: liferay7对外服务类生成（RestService Get Url），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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 {@Overridepublic 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();}@Referencepublic void setUserLocalService(UserLocalService userLocalService) {_userLocalService = userLocalService;}private UserLocalService _userLocalService;}
