找工作神器的主要原理是，根据查询条件去访问相应的网站，通过程序拿到相应网站的HTML代码，再通过相应的正则表达式取相应的信息，再去截取相应的重要信息，再将相应的信息显示在表格里。這里有使用到线程池异步的方式，同时会去三个网站抓取数据，并且会抓取一条解析一条就会在表格里显示出来，这样就避免等待太长时间还看不到结果的尴尬，程序发布后各位园友可以下载程序看看效果如何，还请您能提出宝贵的意见。
整个程序显示的界面效果图：
图片上面显示的是查询条件，输入查询条件后点击查询，下面显示的查询出的数据，分别有三个页签（猎聘网、智联招聘和前程无忧），表格分别显示职位名称、公司名称、公司性质、公司规模、月薪/年薪、工作地点、工作经验、最低学历和发布时间等等信息，日后根据需要还可以继续扩充想要看到的信息，实现看到信息的基本上跟网站上的信息差不多。
查询条件
解析：现在输入的条件有工作地点、薪水范围（上限、下限），关键词、必须包含的关键词，现在暂时只支持以上几种条件，日后可能会继续加入更多的的查询条件（公司名称、公司性质、工作经验、学历要求等等条件，日后再扩展），使查询更方便。
启动查询的代码如下：
通过启动线程池异步的方式同时启动三个网站数据的加载，这样增强用户体验的效果，并且会拿到一条数据解析一条数据，并且及时显示在表格了，这样用户不需要等待太长的时间而看不到结果。
程序启动首先会加载城市对应的ID的一个字典，数据加载如下：

1.前程无忧
前程无忧我相信应该是很多园友找工作的首选，博主就是在这上面注册了简历，并且每次换工作都是在这上面取得了成功，感觉还挺不错，祝愿各位园友都能找到自己称心如意的工作，只要我们大家都一起努力应该都没有问题的。
下面介绍实现逻辑：

以上三个函数的作用分别是线程池启动调用的方法、表格增加一行数据、表格增加行和双击行打开当前行链接四个方法，实现这四个方法即可获取前程无忧的数据，那么获取HTML内容和解析HTML需用另外一个类实现，实现这个类如下：

以上这个类的作用是分别根据网址获取HTML内容，再根据正则表达式获取招聘相关信息，再通过函数截取相关字段的信息，再组装到前台界面，实现数据的显示，这个里面有一个逻辑就是动态每一条招聘信息的连接，再根据连接去获取HTML信息，相当于这中间有两层解析XML的过程。

猎聘网也是最近一两年才兴起的，這个网站上基本上都是很多猎头发布的信息，开的工资大多是都是十多二十万年薪的岗位，只要你具备這个实力可以去這个网站看看，应该会有所收获的，不过這个网站也有部分企业自己发布的招聘信息，如果前面两个网站都没有看到自己满意的求职信息，那么這个网站也可以是自己求职的一个补充，不知各位博友是不是支持我这种观点。
下面介绍实现逻辑：
