使用 javax.ws.rs.core.Response将 cookie 设置为发送到 REST 客户端的 REST 响应。

设置 Cookie 语法

要在 REST API 响应中设置 cookie，请获取 Response引用并使用它的 cookie()方法。

Response.ok().entity(list).cookie(new NewCookie("cookieResponse", "cookieValueInReturn")).build();

REST API 示例代码

我在 REST API 下编写了用于测试目的。

@GET
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response getAllEployees() 
{
	Employees list = new Employees();
	list.setEmployeeList(new ArrayList<Employee>());

	list.getEmployeeList().add(new Employee(1, "JackLi Gupta"));
	list.getEmployeeList().add(new Employee(2, "JackLi Kolenchiskey"));
	list.getEmployeeList().add(new Employee(3, "Tomm Kameron"));

	return Response.ok().entity(list).cookie(new NewCookie("cookieResponse", "cookieValueInReturn")).build();
}

测试

现在让我们使用 Jersey 客户端代码调用上面的 REST API。

public static void main(String[] args) 
{
	Client client = ClientBuilder.newClient( new ClientConfig().register( LoggingFilter.class ) );
	WebTarget webTarget = client.target("http://localhost:8080/JerseyDemos/rest").path("employees");

	Invocation.Builder invocationBuilder =  webTarget.request(MediaType.APPLICATION_JSON);
	Response response = invocationBuilder.get();

	Employees employees = response.readEntity(Employees.class);
	List<Employee> listOfEmployees = employees.getEmployeeList();

	System.out.println(response.getCookies());
	System.out.println(response.getStatus());
	System.out.println(Arrays.toString( listOfEmployees.toArray(new Employee[listOfEmployees.size()]) ));
}

输出：

{cookieResponse=cookieResponse=cookieValueInReturn;Version=1}
200
[Employee [id=1, name=JackLi Gupta], Employee [id=2, name=JackLi Kolenchiskey], Employee [id=3, name=Tomm Kameron]]
