Maven Tomcat Embedded

问题:

I am trying to run a Spring webapp using maven with the

mvn tomcat:run 

command, but whenever I navigate to http://localhost:8080/myApp, I get the error: "The requested resource () is not available". Nothing shows up in the logs. I think my app is supposed to be deployed to "/" instead of "/myApp". Is there a way to do this?

Maven output log:

The documentation for the maven tomcat plugin here states The default context path is /${project.build.finalName}, which itself defaults to /${artifactId}-${version}.

The preferred way of changing the context path is to change the finalName by adding the following to your pom.xml:

<build>         <finalName>mycontext</finalName> </build> 

Alternatively, a different context path can be specified by adding an explicit plugin configuration block to your pom.xml as follows:

<plugin>         <groupId>org.codehaus.mojo</groupId>         <artifactId>tomcat-maven-plugin</artifactId>         <configuration>                 <path>/mycontext</path>         </configuration> </plugin> 

If you've defined either of those two elements in your pom, then it should be loading at localhost:8080/wherever. Otherwise it'll be at localhost:8080/${artifactId}-${version}
