使用'webapp-runner'运行Spring Boot应用后，它在“ INFO：Starting ProtocolHandler [“ http-nio-8080”]”行中停止

Question

我需要将applocation部署到heroku，它是由Spring Boot创建的，因此，我为它添加了一个webapp-runner.jar插件，现在无法在Heroku上运行，并且在本地计算机上，如果我使用webapp-runner.jar从cmd运行它，则会出现同样的问题。

现在我正在使用亚军9.0.24.0，因为我试图在版本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

那是我从cmd的日志

它应该使用Procfile中的comand命令在本地计算机和Heroku中运行它。 我该如何解决该问题？

Answer 1

这篇文章过去对我有很大帮助，可能对您也很有用。

• 将目录更改为Tomcat的安装位置，然后转到bin 。
• 使用喜欢的nano或vim编辑器打开catalina.sh文件。
• 查找JAVA_OPTS并添加以下行：

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