易宝支付Demo,生产中封装成简洁的代付接口，不用request如何获取项目运行时的真实路径

最近项目在做融360引流，涉及到了易宝支付的代扣和代付。易宝官方给出的demo只能简单运行，而且都是通过form表单的形式提交，返回XML格式。同时接口代码都写在了JSP中看起来不友好。项目在生成中想要用，必须修改整合到自己的项目工程中（文末附我修改的源码下载地址）。

首先说明易宝的版本号：易宝支付-代付代发-商户接入包-V3.3

言归正传，相信易宝官方的demo大家都能获取到，所以这里不再赘述demo的难看点。在这里直接截图给大家说明我修改后的代码。有不好的地方请大家看了代码后及时在下方评论

上图是通过request获取项目的真实路径，以便下面用于获取证书地址，但是实际我们在封装成自己的代码时，传入request是不太好的，因为有可能在我们用的时候，无法获取到request对象。而且这里的功能单一，所以我用下面的方法进行了修改，以便获取到证书真实路径（urlss这里需要替换成自己的当前类全限定名称，TransferParamResolver这个都要替换。下面有可Cp代码）

这里代替为用静态代码块获取证书的真实路径，这里的System.Properties功能还是很多的

//        System.err.println(sysPath);
//        Properties props = System.getProperties();
//        propertis = props.getProperty("user.dir")+"文件分隔符：" + //props.getProperty("file.separator");
//        System.out.println("操作系统的名称：" + props.getProperty("os.name"));
//        System.out.println("操作系统的构架：" + props.getProperty("os.arch"));
//        System.out.println("操作系统的版本号：" + props.getProperty("os.version"));
//        System.out.println("文件分隔符：" + props.getProperty("file.separator"));
//        //在 unix 系统中是＂／＂
//        System.out.println("路径分隔符：" + props.getProperty("path.separator"));
//        //在 unix 系统中是＂:＂
//        System.out.println("行分隔符：" + props.getProperty("line.separator"));
//        //在 unix 系统中是＂/n＂
//        System.out.println("用户的账户名称：" + props.getProperty("user.name"));
//        System.out.println("用户的主文件夹：" + props.getProperty("user.home"));
//        System.out.println("用户的当前工作文件夹：" + props.getProperty("user.dir"));

//        操作系统的名称：Windows 8.1
//        操作系统的构架：amd64
//        操作系统的版本号：6.3
//        文件分隔符：\
//        路径分隔符：;
//        行分隔符：
//        用户的账户名称：雷神
//        用户的主文件夹：C:\Users\雷神
//        用户的当前工作文件夹：D:\JAVAInstall\intelIdeaWorkSpace\TestProject1

　　剩下的就是传参和返回值的获取，这里直接放入所有代码
