通过key，获取.properties文件中的值
news.properties文件：
#title
titleNode=/body/div[5]/div[2]/div[3]/h1/span[1]
#theYear
theYearNode=/body/div[5]/div[2]/div[1]/span[1]/em
#monthAndDay
monthAndDayNode=/body/div[5]/div[2]/div[1]/span[2]
#theTime
theTimeNode=/body/div[5]/div[2]/div[1]/span[3]
#source
sourceNode=/body/div[5]/div[2]/div[2]
#content
contentNode=//*[@id=\"detail\"]
#author
authorNode=//*[@id=\"articleEdit\"]/span[2]
#source的正则表达式
sourceRegex=来源：(.*)
#数据库连接
