Description: 一个自己写的Hadoop MapReduce实例源码，网上看到不少网友在学习MapReduce编程，但是除了wordcount范例外实例比较少，故上传自己的一个。包含完整实例源码，编译配置文件，测试数据，可执行jar文件，执行脚本及操作步骤。学习完此例子后，你能掌握MapReduce基础编程，及如何编译Java文件，打包jar文件，编写shell执行脚本等。后续学习还可以参看本人的CSDN博客，如有问题也可以在线为你解答，不过本人也学习Hadoop不足一年，现学现卖而已，也可能力不能及，有些难的也很有可能不懂。希望能够帮助到学习MapReduce的朋友-A written Hadoop MapReduce example source code line to see a lot of friends in the learning MapReduce programming, but in addition to the wordcount example instance is relatively small, so upload your own. Contains the full example source code, the compiler configuration files, test data, executable jar file, execute the script and steps. Learn this example, you can grasp the the MapReduce basis of programming, and how to compile Java files, packaged jar file, write shell execute the script. Follow-up study can also see my CSDN blog if the problem is also available online for you to answer, but I also learned that for Hadoop less than a year, buying and learning it can also power can not and some difficulty also likely to understand . Want to be able to help to learn MapReduce friend Platform: |

Description: 酒店在线预定app全套源码是一套关于安卓版酒店预定的项目源码包括数据库+jsp服务端+安卓客户端源码，为了测试这套源码mysql的编码问题把我折磨的不轻，最后还是因为技术有限没有解决掉。不过已经不影响测试了，安卓客户端需要在Constant.java文件中更改web端IP地址，如果使用本地计算机+avd测试的话那么avd访问本地计算机的IP是10.0.2.2。初始化完数据有web管理员的帐号但是没有普通用户的帐号，第一次打开客户端需要先注册一个帐号，然后用注册的帐号登录客户端。登录以后可以浏览酒店可以提供的房间信息。也可以直接修改个人帐号信息，可以在线预定房间或者会议室。总体来说是套不错的源码。 -Hotel online booking app full set of source code is a set of about Android version of the hotel reservation project source code, including +jsp server+ client source Zhuo, in order to test the MySQL source coding problem to torture me not light, finally because Technology Co. didn t get rid of. But it does not affect the test, Android client needs to change the web IP address in the Constant.java file, if you use the local computer+avd test, then the IP access to the local computer AVD is 10.0.2.2. Initialization data have web administrator account but no ordinary user account, the first time you need to open the client to register an account, and then use the registered account login client. After log in, you can browse the hotel can provide room information. You can also directly modify the personal account information, you can book a room or conference room online. Overall is a good source. Platform: |

Description: 直连mysql的图书馆管理系统源码是一个Android直连mysql的图书管理系统，遗憾的是，目前只有Android客户端，作者没有把数据库导出来跟客户端放在一起，有兴趣和mysql基础的朋友可以根据DBUtil.java类里面的表名和字段名新建一个mysql数据库，关于Android上是否可以直连mysql数据库网上一直有争议，甚至某大神放话“想Android直连mysql的都是猴子请来的逗逼”，的却即使Android可以直连mysql也是存在很多安全隐患的，因为密码需要写死在程序里面，别人反编译以后很容易获取数据库的用户名密码干些坏事，但是如果是内网使用或者公司内部使用的话应该问题不大,本项目有Android通过jdbc连接mysql的实现代码，但是javaapk没有做有效性测试，网上说直连需要注意下面几点：1. 关闭mysql服务器的防火墙。2. 加入mysql的jdbc包，添加到libs文件夹内。3.ADT和SDK为16及16以下，17以上的不能访问。4.手机和mysq服务器互相ping通。5.添加网络权限 。6.在Thread中连接访问mysql，防止ANR。7.设置mysql允许远程连接。 -Direct source library management system MySQL is a library management system with direct Android mysql, unfortunately, currently only the Android client, the author does not have the derived together with the client, and interested friends can according to the DBUtil.java MySQL foundation class inside the table name and field name of a new MySQL on whether Android can be directly connected to the MySQL online has been controversial, even a great God said to direct Android MySQL is a monkey funny forced, but even if the Android can be directly connected to MySQL is also there are many security risks, because the password needs to be coded in the program, after others decompile easy access to user name password do bad, but if it is used inside the intranet or the company should not be a problem, this project is Andr Oid through JDBC to connect mysql implementation code, but javaapk did not test the validity, said that the on-line direct need to pay attention to the following several Platform: |
