问题描述
第一次尝试，我很快遇到了一个我无法解决的问题.我在同一个程序包中有两个资源，遵循相同的蓝图，但是在运行时，Jersey只找到其中一个.我检查了这两个类是否存在于战争中所包含的jar的相同文件夹中.
Trying Jersey for the first time, I've quickly run into a problem that I can't figure out. I have two resources in the same package, following the same blueprint, but at runtime, Jersey only finds one of them. I have checked that both classes exist in the same folder in the jar included in the war.
更新:如果我在DashboardResource上删除了@Path注释(有效地删除了资源)，则DetailsResource突然变得生动起来.看来细节被某种方式隐藏在仪表板上.
迫切需要一些解决方法！
In desperate need of some ideas of how to resolve this!
事实和代码
版本:Jersey 2.4.1，Apache Tomcat 7.0.47
Versions: Jersey 2.4.1, Apache Tomcat 7.0.47
这个很好用:
package jerseytest;
import javax.ws.rs.*;
@Path("/dashboard")
public class DashboardResource {
@GET
@Produces("text/plain")
public String getDashboard() { return "Dashboard"; }
}
这给了我一个HTTP 404:
This one gives me an HTTP 404:
package jerseytest;
import javax.ws.rs.*;
@Path("/details")
public class DetailsResource {
@GET
@Produces("text/plain")
public String getDetails() { return "Details"; }
}
具有Jersey跟踪的HTTP标头

推荐答案
经过大量的挖掘，我发现问题是我的资源类放在战争中的jar中.这会在Jersey 2.4.1(已在2.5中修复)中的一个错误中.
After a considerable amount of digging, I found that the problem is that I have my resource classes in a jar inside a war. This hits a bug in Jersey 2.4.1, which is fixed in 2.5.
