Maven Tomcat嵌入式 [英] Maven Tomcat Embedded

问题描述

我正在尝试使用带有Maven的Spring Webapp

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

mvn tomcat:run

命令，但是每当我导航到http://localhost:8080/myApp时，都会出现错误:请求的资源()不可用".日志中没有任何内容.我认为我的应用程序应该部署到"/"而不是"/myApp".有办法吗?

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输出日志:

推荐答案

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

更改上下文路径的首选方法是通过将以下内容添加到pom.xml中来更改finalName:

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>

或者，可以通过在pom.xml中添加一个显式插件配置块来指定其他上下文路径，如下所示:

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>

如果您已在pom中定义了这两个元素中的任何一个，则应该在localhost:8080/where处加载它.否则它将位于localhost:8080/${artifactId}-${version}

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}
