Deploy the maven webapp (java web) project on the Heroku platform, herokumaven

To deploy a java web project on Heroku, you must use maven to manage the project.

I. Create a maven webapp Project

Edit the pom. xml file and add the following Configuration:

<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/maven-v4_0_0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>com.lala</groupId>    <artifactId>tangshiyi</artifactId>    <packaging>war</packaging>    <version>1.0.0</version>    <name>tangshiyi Maven Webapp</name>    <url>http://maven.apache.org</url>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>4.11</version>            <scope>test</scope>        </dependency>        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>javax.servlet-api</artifactId>            <version>3.0.1</version>            <scope>provided</scope>        </dependency>        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>jsp-api</artifactId>            <version>2.0</version>            <scope>provided</scope>        </dependency>    </dependencies>    <build>        <finalName>jeecms</finalName>        <plugins>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-compiler-plugin</artifactId>                <version>3.3</version>                <configuration>                    <source>1.8</source>                    <target>1.8</target>                    <verbose>true</verbose>                </configuration>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-dependency-plugin</artifactId>                <version>2.10</version>                <executions>                    <execution>                        <phase>package</phase>                        <goals>                            <goal>copy</goal>                        </goals>                        <configuration>                            <artifactItems>                                <artifactItem>                                    <groupId>org.eclipse.jetty</groupId>                                    <artifactId>jetty-runner</artifactId>                                    <version>9.2.11.v20150529</version>                                    <destFileName>jetty-runner.jar</destFileName>                                </artifactItem>                            </artifactItems>                        </configuration>                    </execution>                </executions>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-war-plugin</artifactId>                <version>2.6</version>                <configuration>                    <warName>tangshiyi</warName>                </configuration>            </plugin>        </plugins>    </build></project>

Ii. Compile the command to run the war package

Create in the root directory of the project

Procfile file (note that the file name must be the same)

Web: java $ JAVA_OPTS-jar target/dependency/jetty-runner.jar -- port $ PORT target/tangshiyi. war

Note that the war package name must be the same as the one configured in pom. xml above.

3. Create the tangshiyi project on github and push the project just created

4. Create an application on heroku and associate it with the newly created Project on github. Just deploy the application.

V. Access

Https: // $ {xxxx} .herokuapp.com/

$ {Xxxx} is the name of the application created in step 4.
