当客户在Java中说"Code不应该有自定义类加载器"时,这究竟意味着什么？我不能做什么？

有没有办法格式化JSON以在视图中显示？这样当我添加新属性时,我的API文档会自动更新？额外的功劳是用CSS包围某些元素来设计它.我也想为XML做这个.

class Student 
{
      static CreateEmpty()
      {
           return new Student() {
                 FirstName: 'Mike',
                 LastName: 'Flynn',
                 Classes: new List<Class>(),
                 School: new School() {
                      Name: 'High School'
                 }
           }
      }
}


<code>
@(Student.CreateEmpty().ToJSON())
</code>

至

<code>

{
     FirstName: 'Mike',
     LastName: 'Flynn',
     Classes: [],
     School: {
          Name: 'High School'
     }
}

</code>

我有一个单一的网页应用程序,都是JavaScript.我注意到每次返回新视图的AJAX调用都会出现JavaScript堆大小.我应该做些什么来清理旧观点？

我无法弄清楚为什么下面代码的时区一直显示UTC而不是EST.在我的本地计算机上它显示EST,即使我在MST时间但在实际服务器上它仍然显示UTC.任何线索？

@JsonIgnore
    public String getDateCreatedFormatted() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(getDateCreated());
        calendar.setTimeZone(TimeZone.getTimeZone("EST"));

        SimpleDateFormat format = new SimpleDateFormat("EEE MMM d yyyy h:mm:ss a z");      

        return format.format(calendar.getTime());
    }

当我在动作上有CompressFilter并且它们是错误时,我没有得到我的ExceptionHandling命中.请求未返回任何响应.如果我删除压缩过滤器然后它返回错误数组就好了.如何在错误上跳过压缩过滤器,或者让它达到第二个？

控制器动作

 [HttpPost, CompressAttribute]
 public virtual ActionResult Builder()

Global.asax中

GlobalConfiguration.Configuration.Filters.Add(new ExceptionHandlingAttribute());

CompressFilter

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class CompressAttribue : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
                var encodingsAccepted = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
                if (string.IsNullOrEmpty(encodingsAccepted)) return;

                encodingsAccepted = encodingsAccepted.ToLowerInvariant();
                var response = filterContext.HttpContext.Response;

                if (encodingsAccepted.Contains("gzip"))
                {
                    response.AppendHeader("Content-encoding", "gzip");
                    response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
                }
                else if (encodingsAccepted.Contains("deflate"))
                {
                    response.AppendHeader("Content-encoding", "deflate");
                    response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
                }
        }
    }

我想知道Java Spring MVC是否有某种与返回部分视图(如ASP.NET MVC)相关的实现？基本上我想返回HTML,绑定到一个对象并将其返回到javascript回调以附加到dom,而不是使用Jquery构建html(这是单调乏味的).如果不是,我可以使用Jquery模板.

为什么我的测试中下面的响应总是为空？

SSO.cs

 public class SSO : ISSO
    {
        const string SSO_URL = "http://localhost";
        const string SSO_PROFILE_URL = "http://localhost";

        public AuthenticateResponse Authenticate(string userName, string password)
        {
            return GetResponse(SSO_URL);
        }

        public void GetProfile(string key)
        {
            throw new NotImplementedException();
        }

        public virtual AuthenticateResponse GetResponse(string url)
        {
            return new AuthenticateResponse();
        }
    }

    public class AuthenticateResponse
    {
        public bool Expired { get; set; }
    }

SSOTest.cs

 [TestMethod()]
public void Authenticate_Expired_ReturnTrue()
{
    var target = MockRepository.GenerateStub<SSO>();
    AuthenticateResponse authResponse = new AuthenticateResponse() { Expired = true }; …

我有一个名为ImporterState的复合表,它与一个名为Importer和State的表相关联.这里发生错误context.Importers.Include(q => q.States).为什么会这样？

{"无效的对象名称'ImporterStates'."}

    [Table("HeadlineWebsiteImport", Schema = "GrassrootsHoops")]
        public class Importer
        {
            public int Id { get; set; }
            public string Name { get; set; }
            public string RssUrl { get; set; }
            public string Type { get; set; }
            public string Keywords { get; set; }
            public bool Active { get; set; }
            public DateTime DateModified { get; set; }
            public DateTime DateCreated { get; set; }

            public int WebsiteId { get; set; }

            public HeadlineWebsite Website …

我想知道在WHERE子句和NULL值中处理多个条件时哪个是更好的性能或最佳实践.

WHERE
    u.id = COALESCE(user_id, u.id) AND
    su.custom_id = COALESCE(student_number, su.custom_id)

要么

WHERE
CASE 
    WHEN user_id IS NOT NULL AND LENGTH(user_id) > 0
    THEN
        u.id = user_id 
    ELSE
        su.custom_id = student_number
    END

为什么这条路线http://localhost:2222/2012-adidas-spring-classic/37不能从下面的路线中获取？我收到404错误.

      public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.IgnoreRoute("{*vti_inf}", new { vti_inf = @"(.*/)?_vti_inf.html(/.*)?" });
            routes.IgnoreRoute("{*vti_rpc}", new { vti_rpc = @"(.*/)?_vti_rpc(/.*)?" });

            #region API

            routes.MapRouteLowercase(
             "NamedHomeEvent",
             "{year}-{name}/{Id}",
             new { controller = "Event", action = "Index", year = DateTime.Now.Year },
             new { year = @"\d{4}", Id = @"\d+" }
            );



   public virtual ActionResult Index(int? id, int? year, string name)
        {
