Minimum pom.xml file for new Maven / Spring MVC pr

问题:

I am completely new to Maven and Spring MVC. What I am looking to do is to set up a new Spring MVC project, using Maven (hopefully this sentence makes sense), and run my web app on Tomcat using Eclipse.

I am following the tutorial at this link and I have a problem with the pom.xml file:

• Getting Started with Maven and Spring

The tutorial asks to create the folder structure, and to create a pom.xml file. For starters they ask to put this line in pom.xml:

xml 4.0.0org.springsource.greenbeans.mavenexample11.0-SNAPSHOTOur Simple Project

But when I do that, my Eclipse throws an error:

[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR]   The project  (D:\projectName\pom.xml) has 1 error
[ERROR]     Non-parseable POM D:\projectName\pom.xml: only whitespace content allowed before start tag and not ` (position: START_DOCUMENT seen `... @1:1)  @ line 1, column 1 -> [Help 2]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

Any idea on what the right minimum pom.xml could be? I tried many things but it didn't work for me...

You need not create folder structure yourself. Maven archtype 'maven-archetype-webapp' does it for you. Here is a good tutorial to guide you through for basic setting up a MVC project in eclipse (and the right approach):

• Create Spring MVC dynamic web project with Maven and make it support Eclipse IDE

The minimal pom.xml file for Spring MVC with Tomcat could be:

<?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.spring.maven</groupId>
    <artifactId>minimal-spring</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>war</packaging>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.3.5.RELEASE</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <path>/</path>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

And then:

$ mvn -Dmaven.tomcat.port=8888 tomcat7:run
