将独立的战争文件从 Spring Boot 部署到 Jetty

Question

我正在尝试将使用 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，我看到了异常：

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：

dependencies {
    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 文档中建议的 ApplicationInitializer 类。我错过了什么？如何克服这个异常？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)
    }

发现问题。初始化程序类正在创建一个新的应用程序构建器，而不是使用输入参数。将其更改为以下效果很好。

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

    }
