在使用'webapp-runner‘运行Spring boot应用程序后，它在一行"INFO: Starting ProtocolHandler [“http-nio-8080”]上停止。“

Question

现在我使用的是runner 9.0.24.0版本，之前我尝试在版本8中运行它……

这是我在pom.xml中的插件

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <executions>
          <execution>
            <goals><goal>copy</goal></goals>
            <configuration>
              <artifactItems>
                <artifactItem>
                  <groupId>com.github.jsimone</groupId>
                  <artifactId>webapp-runner</artifactId>
                  <version>9.0.24.0</version>
                  <destFileName>webapp-runner.jar</destFileName>
                </artifactItem>
              </artifactItems>
            </configuration>
          </execution>
        </executions>
      </plugin>

那是我的配置文件

web: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/*.war

这是我来自cmd的日志。

它应该像在本地机器和Heroku中一样，通过Procfile中的命令来运行它。我该如何解决这个问题呢？

这篇文章在过去对我帮助很大，可能对你也有帮助。

where or >将目录更改为Tomcat的安装位置，然后使用您喜欢的任何编辑器(如

• 或vim.
• Look JAVA_OPTS )转到JAVA_OPTScatalina.sh，并添加以下行：

-Djava.security.egd=file:/dev/./urandom
