部署在Tomcat 7.0.57上的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，它将立即部署并启动。 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，服务器将部署该应用程序，但不会启动它。 当我尝试通过浏览器访问该应用程序时，我得到404响应。

有人知道什么会阻止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setenv.sh来仅为此Tomcat切换了Java版本，默认情况下，catalina.sh在启动时会读取它来设置环境变量。

setenv.sh：

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

在您的Web initiliazr类（扩展了SpringBootServletInitializer ）中，您像下面的方法一样重写了configure(SpringApplicationBuilder application)方法：

@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);
    }

}
