Question

我们有一个Web应用程序，如果我们已经登录，则需要显示一个标头，如果我们没有登录，则需要显示另一个标头。我想在JSP文件中呈现这些服务器端。

这是我的第一次尝试：

WebDelivery.java

package xyz.toold.cuebox.web;

import java.util.HashMap;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import org.glassfish.jersey.server.mvc.Viewable;

@Path("/")
public class WebDelivery {

    @Path("/")
    @GET
    public Viewable index() {
        HashMap<String, Object> model = new HashMap<>();
        model.put("LoggedIn", true);
        return new Viewable("/index", model);
    }

    @Path("/search/")
    @GET
    public Viewable search() {
        return new Viewable("/search/index", true);
    }

    @Path("/user/")
    @GET
    public Viewable user() {
        return new Viewable("/user/index");
    }

    @Path("/board/details/")
    @GET
    public Viewable boardDetails() {
        return new Viewable("/board/details/index");
    }

    @Path("/board/")
    @GET
    public Viewable board() {
        return new Viewable("/board/index");
    }

    @Path("/admin/")
    @GET
    public Viewable admin() {
        return new Viewable("/admin/index");
    }
}

index.jsp

问题是我的if从未触发，因此标题从未显示。我知道else丢失了。我本来可以通过另一个if来实现它的，它被倒置了。

我还尝试过不传递HashMap而是传递普通的boolean，但是它也不起作用。

这是link to my GitLab project。

我在做错什么，还是这完全是错误的方式？

c：如果来自模型的变量
