Upload pictures, restart tomcat picture was gone.

My upload path is thus acquired saveurl = request.getSession () getServletContext () getRealPath ("/") + url..;
database holds the relative address. Uploaded to the tomcat, but in a few days the picture will automatically disappear. Seek solutions

address is war package tomcat \ webapp under ? After redeployment is not overwritten . Save Address replace what outside tomcat directory and then try

restart should not , you will not re- deploy it. You can consider it put elsewhere .

this is because you publish the project the wrong way , every release is the local source code Webroot or Webcontent all copied to the tomcat webapps, which put the picture before uploading to cover
you look at the first nine

you create Server yet , that is bound with tomcat Server, create a good Server, double-click it out

you kind of situation should not happen , right , unless you delete the project , and the release of tomcat when this will happen , there will be pictures do not exist , I hope you say that situation . . .

at startup may be considered to obtain startup directory ($ {catalina_home} / bin), and then in the directory where the increase ( such as picture), down this path , the next thing will save the downloaded here ($ {catalina_home} / bin / picture).

under normal circumstances are not uploaded to the server? This method is to wait until you are really on the line running. Something does not it?

situation should be such that , when you first deploy the project to tomcat
you upload pictures, then the image is saved in the project under tomcat

When you deploy a second time , you do not have the original source project is the last time you saved the image , then you will overwrite the second deployment of the first deployment (with pictures ) project
