Tomcat 7 Maven Plugin multiple context

问题

In my current state of the pom.xml i have

<plugin>  
  <groupId>org.apache.tomcat.maven</groupId>  
  <artifactId>tomcat7-maven-plugin</artifactId>  
  <version>2.0</version>  
  <configuration>  
    <path>/myPath</path>  
  </configuration>
</plugin>

this is working fine. I now am trying to add an extra context for the images on the server, so that the "old" context /myPath is directing to the webapp and /images can be used to address images.
I have tried to add a context file, but when I do this only my /images context is loaded.
Also, I don't want to build the WAR each time (this would be the case if I used two context.xml files for the two contexts)

Is it possible to add a) the context as it is (the current state of development using tomcat7:run AND b) the second context /images that only points to a local folder? And how?

回答1:

~~Although it's answered here, thought it would be good to post how the xml should look like:~~

<plugin>  
  <groupId>org.apache.tomcat.maven</groupId>  
  <artifactId>tomcat7-maven-plugin</artifactId>  
  <version>2.0</version>  
  <configuration>  
    <path>/myPath</path>
    <staticContextPath>/images</staticContextPath>  
  </configuration>
</plugin>

The other answer uses staticContextDocbase instead of staticContextPath, and I can't tell the difference between the two, but one of then should work. Haven't tried it myself, though ;)

Tomcat's doc of these two properties:

staticContextDocbase:

The static context docroot base fully qualified path

staticContextPath:

The static context

~~Could be that fully qualified path is in contrast to relative path.~~

Well, I delved a bit into the plugin and Apache's code and found that you need both staticContextDocbase and staticContextPath.

staticContextDocbase is the path from where the static context should be retrieved by Tomcat. In your case it is C:/images.

staticContextPath is the part in the URL after the http://<hostname>:<port> for which the static context should be sent to client. In your case it is /images.

Maven should be configured like so:

<plugin>  
  <groupId>org.apache.tomcat.maven</groupId>  
  <artifactId>tomcat7-maven-plugin</artifactId>  
  <version>2.0</version>  
  <configuration>  
    <path>/myPath</path>
    <staticContextPath>/images</staticContextPath>
    <staticContextDocbase>C:/images</staticContextDocbase>
  </configuration>
</plugin>

Another note:

As seen here, the plugin uses Tomcat.addContext(String contextPath, String baseDir), staticContextPath is passed as contextPath and staticContextDocbase is passed as baseDir. The doc for baseDir states that it Must exist, relative to the server home.

OTOH, that baseDir is moved as is to Context.setBaseDir(String docBase). The doc on that method for baseDir states that This can be an absolute pathname, a relative pathname, or a URL..

Try the full path then. If it doesn't work go for the relative ;).
