1.在eclipse中安裝tomcat8.5時，報錯：

The Apache Tomcat installation at this directory is version 8.5.6. A Tomcat 8.0 installation is expected.

2.解決辦法：
Windows中

①在Tomcat的安裝目錄中找到lib目錄，再找到catalina.jar。使用壓縮軟件（WinRAR或是好壓）打開它。 ②依次找到並雙擊打開org\apache\catalina\util\ServerInfo.properties 文件

server.info=Apache Tomcat/8.5.6 server.number=8.5.6.0 server.built=Oct 6 2016 20:15:31 UTC

改為：

#Apache Tomcat/8.5.6

server.info=Apache Tomcat/8.0.0

#8.5.6.0

server.number=8.0.0

server.built=Oct 6 2016 20:15:31 UTC

在Linux中改法：

cd [tomcat or tomee home(tomcat目錄)]/lib mkdir catalina cd catalina/ unzip ../catalina.jar vim org/apache/catalina/util/ServerInfo.properties `把版本號改成如下形式:` server.info=Apache Tomcat/8.0.0 server.number=8.0.0 server.built=May 11 2016 21:49:07 UTC 接著把改好的ServerInfo.properties文件添加到catalina.jar中: jar uf ../catalina.jar org/apache/catalina/util/ServerInfo.properties cd .. rm -rf catalina
