myeclipse与mysql连接运行servlet出问题

按赞数排序

java.lang.NumberFormatException: For input string: "3306:myceshi"
这个异常是由于他准备把你的"3306:myceshi"这个值转换为数字，所有是这里出错了
你这个其实是你的数据库连接写法错了改成这样
3306/myceshi
如果不行的话，把你的数据库连接代码或配置文件发到我邮箱：rabbit110423@163.com

你把你的连接代码贴出来

我把它发过去了，请多指教。

/**

  • 链接mysql数据库

  • @author weichk
    */
    public class JDBC {
    private static final String URL = "jdbc:mysql://localhost:3306/myceshi";
    private static final String USER = "root";
    private static final String PASSWORD = "root";

    static {
    try {
    Class.forName("com.mysql.jdbc.Driver");
    } catch (ClassNotFoundException e) {
    System.out.println("加载Mysql数据库驱动失败！");
    }
    }

    /**

    • 获取Connection
    • @return
    • @throws SQLException
    • @throws ClassNotFoundException */ public static Connection getConnection() throws SQLException { Connection conn = null; try { conn = DriverManager.getConnection(URL, USER, PASSWORD); } catch (SQLException e) { System.out.println("获取数据库连接失败！"); throw e; } return conn; }

    /**

    • 关闭ResultSet
    • @param rs */ public static void closeResultSet(ResultSet rs) { if (rs != null) { try { rs.close(); } catch (SQLException e) { System.out.println(e.getMessage()); } } }

你的驱动包有了吗？密码正确？

ext+servlet+mysql编码问题！！彻底崩了
ext+servlet+mysql 的一个管理系统 现在情况是 1. 用户登录到jsp 在文本框输入的参数， a = Ext.getCmp("XXX").getValue()获取不到 a永远为空"" （getCmp("XXX")成功，获取到了该组件，只是getValue为空） 2. 前台直接设置var a = "哈哈" 后台用b =getParameter("XXX")接收成功,输出 b="哈哈" 3. 后台sql 语句查询 sql= "select * from table wherename = '" +b+"'" 结果为空 （但复制System.out.println(""+sql)的sql语句去数据库直接查询是有结果的） 4. 数据库查询出来的数据能争取传到后台也能传到前台 代码问题绝对排除。。。已经被编码弄疯了。最开始把所有设置成UTF-8不行 后来又都设成GBK 更崩。。 求教一下整个mysql到前台到后台的编码设置方法。。平台是Myeclipse 9 自己弄了三天了没弄明白 谢谢了。。

Mysql数据库和Hibernate持久化框架
我想问一下，Mysql数据库中已经建立了主外键关系，MyEclipse中持久化类中还需要建立一对多，多对一的关联映射吗？如果要建立关联映射的话，怎么建。持久化类是我自己手写的，不是自动生成的。急啊！在线等！！！！![图片](https://img-ask.csdn.net/upload/201607/27/1469588406_450924.jpg)![图片](https://img-ask.csdn.net/upload/201607/27/1469588532_442970.jpg)![图片](https://img-ask.csdn.net/upload/201607/27/1469588443_796285.jpg)

Java学习的正确打开方式
在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。 何谓学习？博主所理解的学习，它是一个过程，是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些？
由于我之前一直强调数据结构以及算法学习的重要性，所以就有一些读者经常问我，数据结构与算法应该要学习到哪个程度呢？，说实话，这个问题我不知道要怎么回答你，主要取决于你想学习到哪些程度，不过针对这个问题，我稍微总结一下我学过的算法知识点，以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的，并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构，当然，我也会整理一些看过...

聊聊C语言和指针的本质
坐着绿皮车上海到杭州，24块钱，很宽敞，在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传，然而，对于C语言，指针却是与生俱来的。 那么，什么是指针，为什么大家都想避开指针。 很简单， 指针就是地址，当一个地址作为一个变量存在时，它就被叫做指针，该变量的类型，自然就是指针类型。 指针的作用就是，给出一个指针，取出该指针指向地址处的值。为了理解本质，我们从计算机模型说起...
为什么你学不过动态规划？告别动态规划，谈谈我的经验
动态规划难吗？说实话，我觉得很难，特别是对于初学者来说，我当时入门动态规划的时候，是看 0-1 背包问题，当时真的是一脸懵逼。后来，我遇到动态规划的题，看的懂答案，但就是自己不会做，不知道怎么下手。就像做递归的题，看的懂答案，但下不了手，关于递归的，我之前也写过一篇套路的文章，如果对递归不大懂的，强烈建议看一看：为什么你学不会递归，告别递归，谈谈我的经验 对于动态规划，春招秋招时好多题都会用到动态...
程序员一般通过什么途径接私活？
二哥，你好，我想知道一般程序猿都如何接私活，我也想接，能告诉我一些方法吗？ 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”，还有很多读者问过我类似这样的问题。 我接的私活不算多，挣到的钱也没有多少，加起来不到 20W。说实话，这个数目说出来我是有点心虚的，毕竟太少了，大家轻喷。但我想，恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉，我也算是有经验的人了。 唾弃接私活、做外...

压测学习总结（1）——高并发性能指标：QPS、TPS、RT、吞吐量详解
一、QPS，每秒查询 QPS：Queries Per Second意思是“每秒查询率”，是一台服务器每秒能够相应的查询次数，是对一个特定的查询服务器在规定时间内所处理流量多少的衡量标准。互联网中，作为域名系统服务器的机器的性能经常用每秒查询率来衡量。 二、TPS，每秒事务 TPS：是TransactionsPerSecond的缩写，也就是事务数/秒。它是软件测试结果的测量单位。一个事务是指一...

活到老，学到老，程序员也该如此
全文共2763字，预计学习时长8分钟 图片来源：Pixabay 此前，“网传阿里巴巴要求尽快实现P8全员35周岁以内”的消息闹得沸沸扬扬。虽然很快被阿里辟谣，但苍蝇不叮无缝的蛋，无蜜不招彩蝶蜂。消息从何而来？真相究竟怎样？我们无从而知。我们只知道一个事实：不知从何时开始，程序猿也被划在了“吃青春饭”行业之列。 饱受“996ICU”摧残后，好不容易“头秃了变强了”，即将步入为“高...
Vue快速实现通用表单验证
本文开篇第一句话，想引用鲁迅先生《祝福》里的一句话，那便是：“我真傻，真的，我单单知道后端整天都是CRUD，我没想到前端整天都是Form表单”。这句话要从哪里说起呢？大概要从最近半个月的“全栈工程师”说起。项目上需要做一个城市配载的功能，顾名思义，就是通过框选和拖拽的方式在地图上完成配载。博主选择了前后端分离的方式，在这个过程中发现：首先，只要有依赖jQuery的组件，譬如Kendoui，即使使用...

面试官：关于Java性能优化，你有什么技巧
通过使用一些辅助性工具来找到程序中的瓶颈，然后就可以对瓶颈部分的代码进行优化。 一般有两种方案：即优化代码或更改设计方法。我们一般会选择后者，因为不去调用以下代码要比调用一些优化的代码更能提高程序的性能。而一个设计良好的程序能够精简代码，从而提高性能。 下面将提供一些在JAVA程序的设计和编码中，为了能够提高JAVA程序的性能，而经常采用的一些方法和技巧。 1．对象的生成和大小的调整。 J...
