Tomcat使用與配置

Tomcat組成

Server表明Tomcat

Server包含一個或多個service

　　service由一個或多個Connector和一個Engine組成，多個Connector共享一個Engine

　　　　Connector偵聽指定端口，獲取請求，交給Engin處理

　　　　　　兩個典型Connector:HTTP/JK2 分別處理來自瀏覽器和Apache服務器的請求

　　　　Engine由一個或多個虛擬主機Host組成

　　　　　　Host與某個域名匹配，每一個Host下可運行多個WebApp

　　　　　　　　WebApp根目錄對應Context

tomcat編碼問題、

問題描述：使用tomcat7部署一個新的項目，啓動項目後進入登陸註冊頁面，使用js獲取當前城市的名稱；

                  而後將城市名稱做爲參數傳入後臺獲取城市的區域信息；

                   ajax請求成功，可是返回的信息是獲取區域信息失敗。

<Connector port="11088" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8433" URIEncoding="UTF-8"/>

若是server.xml的Connector配置中不設置URIEncoding，

  <!-- ==================== Default Welcome File List ===================== -->
  <!-- When a request URI refers to a directory, the default servlet looks  -->
  <!-- for a "welcome file" within that directory and, if present, to the   -->
  <!-- corresponding resource URI for display.                              -->
  <!-- If no welcome files are present, the default servlet either serves a -->
  <!-- directory listing (see default servlet configuration on how to       -->
  <!-- customize) or returns a 404 status, depending on the value of the    -->
  <!-- listings setting.                                                    -->
  <!--                                                                      -->
  <!-- If you define welcome files in your own application's web.xml        -->
  <!-- deployment descriptor, that list *replaces* the list configured      -->
  <!-- here, so be sure to include any of the default values that you wish  -->
  <!-- to use within your application.                                       -->

web.xml配置文件中的路徑

classpath指WEB-INF/classes/

classpath 和 classpath* 區別： 

• classpath：只會到你的class路徑中查找找文件; 
• classpath*：不只包含class路徑，還包括jar文件中(class路徑)進行查找.
