1.我的连接URL格式是：ct=DriverManager.getConnection("jbdc:sqlserver://localhost:1433;DatabaseName=mytest","sa","supersun"); 2.驱动字符是：Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 3Sqljdbc42.jar包已经加入C:\Program Files\Java\jre1.8.1\lib\ext文件夹下了； 为什么还是显示没有合适的驱动呢，小白求救

如题，我的系统是win10，hosts里的内容是 # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. 192.168.1.104 windows10.microdone.cn 请问这个问题如何解决？

我按网上给的一些解决办法尝试都没成功 TCP/IP已经启用，并且ip1和10的地址被设定为127.0.0.1，all端口设定为1433 ms-dos中输入telnet 127.0.0.1 1433，则出现了一个名为telnet 127.0.0.1 新的控制台，运行后错错误如下：另外，因为工作方面的原因最近经常要用java连接sql server，中间出现错误但是却不理解，有没有那本书是专门讲解这些错误的意义的 com.microsoft.sqlserver.jdbc.SQLServerException: 用户 'sa' 登录失败。 ClientConnectionId:cd23a148-7cb6-4bc9-86de-e10675fe5d1b at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:216) at com.microsoft.sqlserver.jdbc.TDSTokenHandler.onEOF(tdsparser.java:254) at com.microsoft.sqlserver.jdbc.TDSParser.parse(tdsparser.java:84) at com.microsoft.sqlserver.jdbc.SQLServerConnection.sendLogon(SQLServerConnection.java:2908) at com.microsoft.sqlserver.jdbc.SQLServerConnection.logon(SQLServerConnection.java:2234) at com.microsoft.sqlserver.jdbc.SQLServerConnection.access$000(SQLServerConnection.java:41) at com.microsoft.sqlserver.jdbc.SQLServerConnection$LogonCommand.doExecute(SQLServerConnection.java:2220) at com.microsoft.sqlserver.jdbc.TDSCommand.execute(IOBuffer.java:5696) at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(SQLServerConnection.java:1715) at com.microsoft.sqlserver.jdbc.SQLServerConnection.connectHelper(SQLServerConnection.java:1326) at com.microsoft.sqlserver.jdbc.SQLServerConnection.login(SQLServerConnection.java:991) at com.microsoft.sqlserver.jdbc.SQLServerConnection.connect(SQLServerConnection.java:827) at com.microsoft.sqlserver.jdbc.SQLServerDriver.connect(SQLServerDriver.java:1012) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at zidingyi.GetConnectionSqlServer.getConnectionSqlServer(GetConnectionSqlServer.java:24) at zidingyi.Try.main(Try.java:8) 我的代码如下 ``` public class GetConnectionSqlServer { public void getConnectionSqlServer() { String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver"; String dbURL = "jdbc:sqlserver://MIAO-PC\\MIAO\\\\SQLEXPRESS:1433;databasename=stmodel"; // 1433是端口，"USCSecondhandMarketDB"是数据库名称 String userName = "sa"; // 用户名 String userPwd = "sa"; // 密码 Connection dbConn = null; try { Class.forName(driverName).newInstance(); System.out.println("驱动加载成功"); } catch (Exception ex) { System.out.println("驱动加载失败"); ex.printStackTrace(); } try { dbConn = DriverManager.getConnection(dbURL, userName, userPwd); System.out.println("成功连接数据库！"); } catch (Exception e) { System.out.println("地址端口数据库用户名密码出错"); e.printStackTrace(); } finally { try { if (dbConn != null) dbConn.close(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } ```

使用sqljdbc.jar连接jdbc时: 通过端口 1433 连接到主机 127.0.0.1 的 TCP/IP 连接失败。错误:“Connection refused: connect。请验证连接属性。确保 SQL Server 的实例正在主机上运行，且在此端口接受 TCP/IP 连接，还要确保防火墙没有阻止到此端口的 TCP 连接。 代码如下: String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";//驱动器 String url = "jdbc:sqlserver://127.0.0.1:1433;DatabaseName=xxxx"; String user = "sa";//用户名 String password = "sa";//密码 try { Class.forName(driver); // 加载数据库驱动 // 构建连接 Connection conn = DriverManager.getConnection(url, user, password); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); 防火墙已经关闭 没有阻止接口 telnet localhost 1433是通的 但是127.0.0.1 1433就提示连接端口:1433 失败 ping 127.0.0.1是没问题的 C盘etc/hosts中的对应localhost与127.0.0.1的内容为: # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost Sqlserver配置器已经打开 IIPALL的固定端口是1433 一直保持侦听状态 只有一个实例MSSQLSERVER windows事件日志上的错误是:服务器无法在 'any' <ipv4> 1434 上侦听。错误: 0x277a。若要继续，请通知您的系统管理员。 查看sqlserver 2012日志错误如下: Server failed to listen on 'any' <ipv4> 1434. Error: 0x277a. To proceed, notify your system administrator 错误: 26024，严重性: 16，状态: 1。 电脑已经重装成win7了 还是这个问题 sql可以和visual studio 2012连接 但是无法和MyElicpse连接 在cmd中执行netstat -ano 只有TCP [::]:1433接口在监听 找不到0.0.0.0:1433和127.0.0.1:1433这两个接口 1434只有UDP [::]:1434和0.0.0.0:1434 执行tasklist|findstr 2448(1433端口PID) 显示进程为sqlservr.exe 1433没有被占用 使用的jar包是sqljdbc4.jar      在之前使用win8的时候 有段时间是可以连接的 当时没有加入tomcat 大约有2到3个月没有使用这个jdbc 再拿出来学习jsp的时候 就一直提示这个错误 因为我要使用tomcat做jsp 要连接jdbc 所以这个问题很急 求大神解决一下啊 重装了好几次系统了 要崩溃了

目前状况，在lnmp环境下，需要远程访问一台服务器上的sqlserver数据库，远程访问已经设置好了 linux下php扩展pdo_dblib 和 mssql 都已经安装完毕，并且 freetds 访问远程数据库都是 没问题的  然而在php中做连接时却出现问题，php代码  报错 SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9)

最近在学习 PHP，搭建环境后，在 Safari 能打开 http://localhost，显示 It works! 接着改动了 DocumentRoot 的地址为 Sites 文件的地址(“/Users/用户名/Sites”)，让后创建新 php 文件，能在 Safari 中通过 http://localhost/xxx.php 可后来就不能打开了，只能打开 http://localhost，显示 It works! 这是怎么回事？是哪里配置出错了吗？

我试了好多次，不是数据库链接不上，不知道为什么，然后就是连接上数据库了，然后tomcat能正常启动，但是http://localhost:8080/网页就是打不开,试着改了端口号，关了防火墙，换了浏览器都打不开。用http://127.0.0.1:8080还是无济于事，已经重新配置了很多遍了还是如此，希望各位大神可以指点一下

我在家里的电脑上用eclipse建了一个简单的hibernate工程. 运行的时候碰到no suitable driver found for jdbc:mysql//localhost:3306/qzhao 异常。 我在网上搜了很多答案，比如把jar放在jre/lib/ext下面，都不行。 奇怪的是在我单位工作电脑上，同样的项目就能work。也没有把jar包放在jre下面。我家里用的是win7，jdk装在C:\pogram files下面。连接配置都是好的。还有家里mysql是和eclipse装在同一台电脑上。工作单位是在服务器上。 请高手解释？昨晚折腾了一夜。最后网速暴慢就睡觉了。 [b]问题补充：[/b] 我的不是一个web程序，就是一个普通的eclipse java project。我已经把jar加到eclipse project里面了。而且用这个jar包用一般的java code可以连接啊 [b]问题补充：[/b] 谢谢各位的答案 出现这样的情况，一般有四种原因： 一：连接URL格式出现了问题(Connection conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/XX","root","XXXX") [qzhao]:我的配置如下： <!-- Database connection settings --> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://10.111.3.244:3306/qzhao_opbook</property> <property name="connection.username">qzhao</property> <property name="connection.password">qzhao</property> <!-- JDBC connection pool (use the built-in) --> <property name="connection.pool_size">1</property> <!-- SQL dialect --> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <!-- Enable Hibernate's automatic session context management --> <property name="current_session_context_class">thread</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">true</property> <!-- Drop and re-create the database schema on startup --> <property name="hbm2ddl.auto">update</property> <mapping resource="org/hibernate/tutorial/domain/Event.hbm.xml" /> 而且在我单位电脑能work 二：驱动字符串出错(com.mysql.jdbc.Driver) 三：Classpath中没有加入合适的mysql_jdbc驱动（驱动要和你的数据库版本一致） 这个我用的是mysql-connector-java-5.0.4-bin.jar，数据库是5.0 四：驱动jar包放的位置不对 我把它加到eclipse project build path里面的。同样在单位电脑上可以工作的。所以我很疑惑，难道是因为家里的电脑jdk路径下面有空格或者是win7的原因？？ [b]问题补充：[/b] 问题找到了，是url错了。 分就给walsh吧

昨天早上通过远程的方式 review 了两名新来同事的代码，大部分代码都写得很漂亮，严谨的同时注释也很到位，这令我非常满意。但当我看到他们当中有一个人写的 switch 语句时，还是忍不住破口大骂：“我擦，小王，你丫写的 switch 语句也太老土了吧！” 来看看小王写的代码吧，看完不要骂我装逼啊。 private static String createPlayer(PlayerTypes p...

原博客再更新，可能就没了，之后将持续更新本篇博客。

提到“程序员”，多数人脑海里首先想到的大约是：为人木讷、薪水超高、工作枯燥…… 然而，当离开工作岗位，撕去层层标签，脱下“程序员”这身外套，有的人生动又有趣，马上展现出了完全不同的A/B面人生！ 不论是简单的爱好，还是正经的副业，他们都干得同样出色。偶尔，还能和程序员的特质结合，产生奇妙的“化学反应”。 @Charlotte：平日素颜示人，周末美妆博主 大家都以为程序媛也个个不修边幅，但我们也许...

今天给你们讲述一个外包程序员的幸福生活。男主是Z哥，不是在外包公司上班的那种，是一名自由职业者，接外包项目自己干。接下来讲的都是真人真事。 先给大家介绍一下男主，Z哥，老程序员，是我十多年前的老同事，技术大牛，当过CTO，也创过业。因为我俩都爱好喝酒、踢球，再加上住的距离不算远，所以一直也断断续续的联系着，我对Z哥的状况也有大概了解。 Z哥几年前创业失败，后来他开始干起了外包，利用自己的技术能...

场景 日常开发，if-else语句写的不少吧？？当逻辑分支非常多的时候，if-else套了一层又一层，虽然业务功能倒是实现了，但是看起来是真的很不优雅，尤其是对于我这种有强迫症的程序"猿"，看到这么多if-else，脑袋瓜子就嗡嗡的，总想着解锁新姿势：干掉过多的if-else！！！本文将介绍三板斧手段： 优先判断条件，条件不满足的，逻辑及时中断返回； 采用策略模式+工厂模式； 结合注解，锦...

有小伙伴问松哥这个问题，他在上海某公司，在离职了几个月后，前公司的领导联系到他，希望他能够返聘回去，他很纠结要不要回去？ 俗话说好马不吃回头草，但是这个小伙伴既然感到纠结了，我觉得至少说明了两个问题：1.曾经的公司还不错；2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说，松哥之前也有过类似的经历，今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点，就是离职了也没必要和老东家弄的苦...

编程语言层出不穷，从最初的机器语言到如今2500种以上的高级语言，程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新，一边面临由于许多代码已存在，程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法，它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中，可视化建模来组装和配置应用程序。这样一来，开发者直...

前几天我们公司做了一件蠢事，非常非常愚蠢的事情。我原以为从学校出来之后，除了找工作有测试外，不会有任何与考试有关的事儿。 但是，天有不测风云，公司技术总监、人事总监两位大佬突然降临到我们事业线，叫上我老大，给我们组织了一场别开生面的“考试”。 那是一个风和日丽的下午，我翘着二郎腿，左手端着一杯卡布奇诺，右手抓着我的罗技鼠标，滚动着轮轴，穿梭在头条热点之间。 “淡黄的长裙~蓬松的头发...
