有时候在进行开发的过程中，需要自己写个测试类来进行某个局部功能的测试，在测试的过程中，需要引入第三方jar包或者公司其他成员的帮助类，比如说：我需要测试一个

写好之后上传到服务器上，需要自己在java文件目录上传好依赖的第三方jar包，然后编译：

1
javac -cp commons-beanutils-1.8.3.jar:commons-collections-3.2.1.jar:commons-lang-2.6.jar:commons-logging-1.2.jar:json-lib-2.4-jdk15.jar: ZyhqErrorMsgDemo.java

切记：最后一个jar包后的：后面要加上一个空格再引入自己的Java文件

执行的命令:

1
javac -cp commons-beanutils-1.8.3.jar:commons-collections-3.2.1.jar:commons-lang-2.6.jar:commons-logging-1.2.jar:json-lib-2.4-jdk15.jar: ZyhqErrorMsgDemo
