資源簡介

HttpClient在當今Java應用中的位置越來越重要。從該項目的變遷過程我們不難發現，其已經從apache-commons眾多的子項目中剝離，一躍成為如今的頂級項目，可見它的分量。然而隨著項目的升級和架構的調整，很多以前常用的類和方法都已被打上了@Deprecated注解，作為一個有代碼潔癖的程序猿，我們也有必要升級一下工具類，讓代碼更加整潔。 另外在項目中正好需要訪問https協議的接口，而對應的服務器沒有購買商業CA頒發的正式受信證書，只是做了個自簽名（聯想一下12306網站購票時提示的那個警告信息），默認情況下通過HttpClient訪問會拋出異常。相關文章參閱：http://blog.csdn.net/chaijunkun/article/details/40145685
