目前Suboveive SVN连接器的安装因Eclipse Oxygen而失败.

如何找出 HttpClient 4.3 的实际超时值？我知道如何显式设置它们，但如果我不覆盖它们，我想知道隐式使用哪些值。

例子

import org.apache.http.client.config.RequestConfig;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.DefaultHttpRequestRetryHandler;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.params.HttpParams;

public class HttpClientDefaults
{

    public static void main(String[] args)
    {       
        RequestConfig config = RequestConfig.custom().build();
        System.out.println("ConnectionRequestTimeout: " + config.getConnectionRequestTimeout());
        System.out.println("ConnectTimeout: " + config.getConnectTimeout());
        System.out.println("SocketTimeout: " + config.getSocketTimeout());
        CloseableHttpClient client = HttpClientBuilder.create().setRetryHandler(new DefaultHttpRequestRetryHandler()).build();
        HttpParams params = client.getParams();
        System.out.println(params.getParameter("http.socket.timeout"));
    }

}

输出

ConnectionRequestTimeout: -1
ConnectTimeout: -1
SocketTimeout: -1
Exception in thread "main" java.lang.UnsupportedOperationException

client.getParams() 抛出 java.lang.UnsupportedOperationException 异常。有人知道读出将要使用的实际值的方法吗？

有没有办法像javax.servlet.Filter在 Servlet 3.x 容器中一样运行 Jersey servlet 容器 (2.x) 无描述符？我需要与我的服务一起提供静态资源，因此需要使用jersey.config.servlet.filter.forwardOn404orjersey.config.servlet.filter.staticContentRegex仅在根据 Javadoc 作为过滤器运行时才起作用

该属性仅当 Jersey servlet 容器配置为作为 javax.servlet.Filter 运行时才适用，否则该属性将被忽略。

web.xml我想彻底摆脱

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
            http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    version="3.1">
    <display-name>My-Webservice</display-name>

    <filter>
        <filter-name>Jersey Filter</filter-name>
        <filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.foo.webservices.MyApplication</param-value>
        </init-param>
    </filter>
</web-app>

并在我的定制Application课程中拥有一切

@ApplicationPath(value = "/")
public class MyApplication extends ResourceConfig
{    
    public MyApplication()
    {
        packages("com.foo.webservices.services");
        property(ServletProperties.FILTER_FORWARD_ON_404, true);
    }
}

不幸的是，官方文档（https://jersey.java.net/documentation/latest/deployment.html#deployment.servlet.3）没有说明有关过滤器的任何内容。
