java – 如何为使用Spring Cache缓存的Spring Web Service设置正确的Last-Modified标头值？
我有这样的
Spring MVC控制器：
@Controller
@RequestMapping(value = "/user")
public class UserController {
.....
@Cacheable(value = "users",key = "#id")
@RequestMapping(value = "/get",method = RequestMethod.GET)
@ResponseBody
public User getUser(Long id){
return userService.get(id);
}
....
}
我想将标题Last-Modified添加到GetUser Web服务的HTTP响应中.
如何在我的商店中添加缓存时获得正确的日期？
如何将此日期的Last-Modified标题添加到Spring Controller方法的响应中？
解决方法
这个怎么样：
@Controller
@RequestMapping(value = "/user")
class UserController {
@Cacheable(value = "users",key = "#id")
@RequestMapping(value = "/get",method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<User> getUser(Long id) {
HttpHeaders headers = new HttpHeaders();
headers.set("Last-Modified",dateFormat.format(new Date()));
return new ResponseEntity<SecurityProperties.User>(headers,userService.get(id),HttpStatus.OK);
}
}

我目前正在使用 Airflow 2.0 使用 BashOperator 来安排我的 Pentaho 作业，如下例所示：

当我运行它时，有很多与java库相关的错误。这是日志的一部分：

asp.net-web-api – System.Web.Routing.RouteCollection不包含“MapHttpRoute”的定义 – VS 2012,Web API
我刚刚安装了Visual Studio 2012，并开始检查MVC 4和Web Api。
我已经用Web API创建了一个新的MVC 4应用程序。基于一些示例和教程，我开始配置我的路由：
我已经用Web API创建了一个新的MVC 4应用程序。基于一些示例和教程，我开始配置我的路由：
routes.MapHttpRoute(
name: "Controller only",routeTemplate: "api/{controller}"
);
但是，这会导致RouteCollection不包含MapHttpRoute的定义的错误。我是否安装了一些DLL？
据我看到，我已经安装了所有正确的DLL和版本。
解决方法
我已经通过在RouteConfig.cs中添加对System.Web.Http的引用来解决它
asp.net-web-api – Windows.Web.Http.HttpClient WEB API Windows身份验证
我使用
Windows.Web.Http.HttpClient连接到我的WEB API.应用程序没有提示用户名和密码,但最近我通过将AuthorizeAttribute过滤器从Action级别移动到类级别来更改WEB API.现在我的Windows应用商店8.1应用程序提示用户ID和密码.请让我知道如何设置HttpClient不提示登录和密码. any1可以建议我,我需要添加标头到我的httpcleint
使用(Windows.Web.Http.HttpClient httpClient = new Windows.Web.Http.HttpClient())
{
//添加用户代理标头
var headers = httpClient.DefaultRequestHeaders;
//检查用户标头值的安全方法是TryParseAdd方法
//因为我们知道这个标题是可以的,所以我们使用ParseAdd会抛出异常
//值不好 – http://msdn.microsoft.com/en-us/library/windows/apps/dn440594.aspx
headers.UserAgent.ParseAdd("ie");
headers.UserAgent.ParseAdd("Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)");
using (var response = await httpClient.GetAsync(new Uri(url)))
我没有看到发送默认凭据的方法.
解决方法
使用HttpBaseProtocolFilter.AllowUI禁用UI对话框.试试这个：
Windows.Web.Http.Filters.HttpBaseProtocolFilter filter =
new Windows.Web.Http.Filters.HttpBaseProtocolFilter();
filter.AllowUI = false;
HttpClient client = new HttpClient(filter);
Uri uri = new Uri("http://localhost/?basic=1");
var response = await client.GetAsync(uri);
System.Diagnostics.Debug.WriteLine(response);
你需要凭证吗？使用HttpBaseProtocolFilter.ServerCredential.试试这个：
Uri uri = new Uri("http://localhost?ntlm=1");
Windows.Web.Http.Filters.HttpBaseProtocolFilter filter =
new Windows.Web.Http.Filters.HttpBaseProtocolFilter();
filter.AllowUI = false;
// Set credentials that will be sent to the server.
filter.ServerCredential =
new Windows.Security.Credentials.PasswordCredential(
uri.ToString(),"userName","abracadabra");
HttpClient client = new HttpClient(filter);
var response = await client.GetAsync(uri);
System.Diagnostics.Debug.WriteLine(response);
您需要默认的Windows凭据(域凭据)吗？只需将Enterprise Authentication功能添加到Package.appxmanifest即可.
