war包太大，無法成功部署到tomcat伺服器

使用網頁把項目的war部署到tomcat伺服器，它有一個大小限制，預設最大值是50m，雖然當你部署的項目大于50m時，他就會出現以下錯誤

eploy Upload Failed, Exception: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (76606810) exceeds the configured maximum (52428800)

解決的辦法如下：

進入tomcat的安裝路勁/usr/local/tomcat/webapps/manager/WEB-INF/web.xml

修改上傳的檔案的最大值，預設值是50M，這裡在後面加個0,改為500M

<multipart-config>

      <!-- 500MB max -->

      <max-file-size>524288000</max-file-size>

      <max-request-size>524288000</max-request-size>

      <file-size-threshold>0</file-size-threshold>

    </multipart-config>

  </servlet>

修改成功之後記得重新開機tomcat伺服器
