1.1  修改Eclipse JRE

1.2  新增JAVA_HOME\lib\tools.jar

選擇1.8版本的JRE：

選中行進行編輯新增：

1.3  Eclipse Maven 打包設定

選擇打包專案：

設定JRE：

1.4  遷移到生產及測試環境必須重新設定JAVA_HOME

升級部署環境的JDK版本為1.8.x並設定相應的JAVA_HOME等環境變數。

2      Windows JDK升級Tomcat服務問題處理

在JDK1.7.x安裝的服務預設使用的是之前的JDK版本，需要解除安裝並重新安裝.

2.1  解除安裝Tomcat服務

cd 進入TOMCAT_HOME\bin目錄輸入：

TOMCAT_HOME\bin\service unstall TOMCAT-SERVER-NAME

2.2  安裝Tomcat服務

cd 進入TOMCAT_HOME\bin目錄輸入：

TOMCAT_HOME\bin\service install TOMCAT-SERVER-NAME

由此可見Tomcat服務安裝時是找到了JAVA_HOME環境變數來進行配置的，所以JDK升級後應用程式如果依賴JDK8必須要重新安裝服務。
