Tomcat 7.0.57 上部署的 Spring Boot 1.2.2 应用程序无法启动

Question

我写了一个 Spring Boot 应用程序。当我将它作为 WAR 放入本地测试 Tomcat 7.0.57 (XAMPP) 的 webapps 文件夹中时，它会立即部署并启动。当我在具有相同 Tomcat 版本的专用测试服务器上执行相同操作时，服务器会部署应用程序但不会启动它。当我尝试通过浏览器访问应用程序时，我收到 404 作为响应。

有人知道什么会阻碍服务器启动应用程序？

问题是我的 Tomcat 7 使用的是 Java 6。

提示是 catalina.out 日志的以下行：

INFO: JSR 356 WebSocket (Java WebSocket 1.0) support is not available when running on Java 6. To suppress this message, run Tomcat on Java 7, remove the WebSocket JARs from $CATALINA_HOME/lib or add the WebSocket JARs to the tomcat.util.scan.DefaultJarScanner.jarsToSkip property in $CATALINA_BASE/conf/catalina.properties. Note that the deprecated Tomcat 7 WebSocket API will be available.

我通过在 tomcat-7/bin 中创建一个 setenv.sh 为这个 Tomcat 切换了 Java 版本，默认情况下由 catalina.sh 在启动时读取它以设置环境变量。

setenv.sh:

export JAVA_HOME=/usr/java/jdk1.7.0_09

在您的 web initiliazr 类（扩展 SpringBootServletInitializer 的类）中，您是否像下面这样覆盖了方法 configure(SpringApplicationBuilder application)：

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}
