在Tomcat下的war文件中的index.jsp

Question

I am trying to run simple web app on my local tomcat - the app is basically what you get when you crate "web application" in IntelliJ, so the directory structure is "vanilla". I am literally not touching either index.jsp or web.xml.

I am doing this under Maven, so here is my pom file:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.testapps</groupId>
    <artifactId>Test_App_1</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>war</packaging>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.6.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <configuration>
                    <webXml>web\WEB-INF\web.xml</webXml>
                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

So here is what I am doing:

1. Building this "project" under maven: mvn compile install
2. I am copying app_name.war file from my local repo into tomcat webapps directory
3. Running tomcat: catalina start
4. I can see that my application IS THERE in manager, but when I try to enter it (or when I just type http://localhost:8080/app_name ) the 404 error occurs.

What I am doing wrong? Am I not understanding some basic concept or missing some basic thing? Should I somehow explicitly INCLUDE this index.jsp into my .war file somehow? If so, how do I do that under IntelliJ? I am literally just trying to run this "vanilla" application and I am under the impression, that index.jsp should be a part of this .war file and it should be displayed "automatically". And when I do it manually, so I will just create some TestDirectory in webapps folder, copy the same index.jsp file and place it in that directory, and then acces it http://localhost:8080/TestDirectory - it automatically displays this index.jsp file as it should.

Sorry for, probably, dumb question, I am really new to this and I couldn't find a solution.

在构建并重新部署并在服务器中测试之后删除maven-war-plugin
