eclipse中Server Locations選項

這幾天在開發的過程，使用

mvn tomcat7:redeploy

指令打包部署到伺服器上是，發現有報記憶體洩漏的日志。于是想在本地測試一下，看是哪裡沒有釋放好記憶體。日志如下：

可能是因為是spring-boot項目的原因，是以我在tomcat中删除項目時，控制台上并沒有列印日志。是以我想把manager加上，這樣我可以在控制台上解除安裝項目，指令行一樣解除安裝的目的。這就需要修改Server Locations了，以下說明Server Locations幾項目設定。

Server Locations包括三個選項：

• Use workspace metadata(dose not modify Tomcat installation) 使用workspace的工作空間，不影響本地Tomcat安裝配置

• Use Tomcat installation (takes control of Tomcat installation)

  使用和控制本地安裝的Tomcat

• Use custom location (dose not modify Tomcat installation)

  使用自定義的目錄，不影響本地Tomcat安裝配置

我們平時使用的配置都是第一項，tomcat啟動的時候，war包和日志實際的路徑可以在

Open launch configuration

這裡找到：

我今天要使用的是第二項

Use Tomcat installation

，啟動後，可以在tomcat的目錄下看到

wtpwebapps

目錄（其中wtpwebapps目錄可以改為webapps，因不想影響裡邊的程式就沒改），并且在logs目錄下也能看到通路日志。

然後在

%tomcat%/conf/tomcat-users.xml

增加使用者,再從

http://localhost:8080/manager/html

登入就可以部署和解除安裝war應用了。
