Java – deploy with parameters * War file

I have a web project with rest API I want to deploy five copies of it on the Tomcat server For example:

deploy test1.war -conf <path1>
    deploy test2.war -conf <path2>
    deploy test3.war -conf <path3>

Can I do this in Tomcat? Do you have any choice?

Solution

I decided to get the appropriate configuration file for the app at runtime

String path = MainApp.class.getProtectionDomain().getCodeSource().getLocation().getPath();
String decodedPath = java.net.URLDecoder.decode(path,"UTF-8");
// decodedPath - "D:/apache-tomcat-7.0.81/apache-tomcat-7.0.81/webapps/warname/WEB-INF/classes/com/gieseckedevrient/rsp/servertester/MainApp.class"

2) Parse the decoded path to get only "warname":

String parentName = "";
java.io.File parentFile = null;
while (!"WEB-INF".equals(parentName)) {
  File file = new File(decodedPath);
  parentFile = file.getParentFile();
  parentName = parentFile.getName();
  decodedPath = parentFile.getAbsolutePath();               
  }
String realWarName = parentFile.getParentFile().getName();

3) At Tomcat_ Create the file "setenv. Bat" in home} / bin / and insert this code into it (warname.config.file of warname.war and warname2.config.file of warname2.war):

set CATALINA_OPTS=-Dwarname.config.file=D:\app.properties -Dwarname2.config.file=D:\app2.properties

4) Use the following code to read the appropriate env variable:

String configFile = System.getProperty(realWarName + ".config.file");
// configFile - "D:\app.properties" for warname.war
// configFile - "D:\app2.properties" for warname2.war
