从Spring Boot到Jetty部署独立war文件

我试图将使用Spring Boot构建的war文件部署到独立的Jetty webapps文件夹并启动Jetty . 在Spring上下文初始化期间，我看到异常：

Caused by: 
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
    at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.onRefresh(EmbeddedWebApplicationContext.java:135)
    at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:476)

下面是我的gradle依赖列表：

    compile(
        "org.springframework.boot:spring-boot-starter-actuator:1.1.4.RELEASE",
        "org.springframework.security:spring-security-web:3.2.3.RELEASE",

    )
    compile ("org.springframework.boot:spring-boot-starter-web:1.1.4.RELEASE") {
        exclude module:'spring-boot-starter-tomcat'
    }

我正在使用Spring Boot docs中建议的 ApplicationInitializer 类 . 我错过了什么？如何通过此例外？我有Jetty 9.x服务器 .

class ApplicationInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        Properties props = getPropertiesFromArgs()
        return new SpringApplicationBuilder([Application, "classpath:/META-INF/com/foo/testapp/bootstrap.xml"] as Object[])
            .properties(props)
    }
