私は、サーバーを起動していた場合、それは入門れるが、私はエラーを取得しています。APIの呼び出しを行うことが、このことはできませんが原因。これらはエラーです。

問題は、このクラスにしました
@Component public class APIsAuthentications implements Filter
そのために使用されていますAPIs Authentications。このクラスではと呼ばれる方法があります：
@Override public void doFilter(ServletRequest servletRequest, ServletResponse response, FilterChain chain)throws IOException, ServletException
これは、検証されるAPIsと期待token/authenticationしてrequests header。ここでdoFilterの方法は、ベースURLも、応答を与えるためのAPIを検証します401。Tomcatで何も問題はありません。
最後に、私は中1の条件を入れてdoFilter、それはだ場合の方法base URLs/Open URLs、これらのAPIの無い検証があります。
ローカルマシンのための私のベースURL： http://localhost:8080/projects/
問題が解決しました ！！！:)
