我正在研究过滤器在Angularjs中是如何工作的,我看到我们需要发送2组括号.

$filter('number')(number[, fractionSize])

它意味着什么,我们如何使用JavaScript处理它？

正在阅读Joel Spolsky关于字符编码的'The Absolute Minimum'.据我所知,ASCII是一种代码点+编码方案,在现代,我们使用Unicode作为代码点方案,使用UTF-8作为编码方案.它是否正确？

嗨,任何人都可以指出我们如何将order by子句作为命名参数传递给hql

例如:

作品:

select tb from TransportBooking as tb

and TIMESTAMP(tb.bookingDate, tb.bookingTime) >= current_timestamp() order by tb.bookingDate

不起作用:

select tb from TransportBooking as tb

and TIMESTAMP(tb.bookingDate, tb.bookingTime) >= current_timestamp() order by :order

尝试使用javax.net.ssl.HttpsURLConnection连接到URL时,我得到"java.lang.ClassCastException".

我使用的是Weblogic Server 10.3.4.

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;



import java.security.cert.X509Certificate;


import java.io.BufferedReader;
import java.io.InputStreamReader;

import java.net.HttpURLConnection;
import java.net.URL;

public class GatewayConnect {


public void ConnectURL()
{
    try
    {

        System.out.println("***** Inside Class File *****");
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] {new X509TrustManager() {
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }

关于类java.lang.ThreadLocal的javadoc让我感到困惑.他们说每个访问线程局部变量的线程都有自己独立初始化的变量副本.下面是一个示例(不是真实的生活示例),它证明了线程局部变量中保存的变量可以被许多线程共享:

package com.mohamad.test.threadlocal;

import java.util.List;

public class ThreadLocalExample {

    private static final ThreadLocal<List<Integer>> myThreadLocal = new ThreadLocal<List<Integer>>();

    public static List<Integer> get() {
        return (myThreadLocal.get());
    }

    public static void set(List<Integer> value) {
        myThreadLocal.set(value);
    }
}


package com.mohamad.test.threadlocal;

import java.util.ArrayList;
import java.util.List;


public class TestThreadLocal implements Runnable {

    private static List<Integer> MY_TEST_LIST = new ArrayList<Integer>(){
        /** The serialVersionUID */
        private static final long serialVersionUID = -2419885728976816054L;
        {add(1);}
    };


    /* (non-Javadoc)
     * @see java.lang.Runnable#run()
     */
    public void run() {
        ThreadLocalExample.set(MY_TEST_LIST);
        List<Integer> integers = …
