眼下，需要Heroku上述部署java web工程，该项目必须使用maven管理

一：新maven webapp工程

编者pom.xml档，增加下面的配置为例，

<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">

            </plugin>

            <plugin>

                        <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>

                <configuration>

                    <warName>tangshiyi</warName>

                </configuration>

            </plugin>

        </plugins>

    </build>

</project>

二：编写执行war包的命令

在项目的根文件夹下新建

Procfile 文件（注意文件名称要一模一样）

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

注意这里的war包的名字须要和上面pom.xml里面配置的要一样

三：在github上面创建tangshiyi项目，并刚才创建的项目push上去

四：在heroku上面新建一个应用并关联github上面刚刚新建的项目，部署就可以

五：訪问

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

${xxxx}为第四步创建应用的名字
