java - 使用“webapp-runner”运行 Spring boot 应用程序后，它停在“INFO：启动 ProtocolHandler [“http-nio-8080”]”行上

Question

我需要将应用程序位置部署到heroku，它是使用Spring Boot创建的，因此我添加了一个webapp-runner.jar插件，现在它无法在Heroku上运行，并且在本地机器上我得到了如果我使用 webapp-runner.jar 从 cmd 运行它，同样的问题。

现在我正在使用 runner 9.0.24.0 版本，之前我尝试在版本 8 中运行它...

那是我在 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Procfile

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

那是我来自 cmd 的日志

它应该像在本地机器和 Heroku 中一样使用 Procfile 中的命令运行它。我怎样才能解决这个问题？

这篇文章在过去帮助了我很多，也可能对你有用。

• 将目录更改为安装 Tomcat 的位置，然后转到bin.
• 使用catalina.sh您喜欢的任何编辑器nano或vim.
• 查找JAVA_OPTS并添加这一行：

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