tomcat 上的 Spring Boot war 文件：errorPageFilter 无法转换为 TomcatEmbeddedServletContainerFactory

Question

我正在尝试将一个简单的 Spring Boot 应用程序转换为一个 war 文件以部署到我的 tomcat 服务器，但我不断收到此错误：

Caused by: org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'errorPageFilter': Initialization of bean failed; nested exception is java.lang.ClassCastException: org.springframework.boot.context.web.ErrorPageFilter cannot be cast to org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory

当我将这个 Spring Boot 应用程序作为 jar 运行时，它可以完美运行，但如果我创建了一个战争，它会给我带来错误。据我所知，我完美地遵循了 Spring 指南：http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

这是我的应用程序类：

@Configuration
@EnableWebMvc
@ComponentScan({"XXX"})
@EnableAutoConfiguration
@EnableConfigurationProperties
@SpringBootApplication
@EnableAsync
public class Application extends SpringBootServletInitializer {

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

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

}

这是我的 build.gradle：

buildscript {
    ext {
        springBootVersion = '1.2.6.RELEASE'
    }
    repositories {
        maven { url "http://repo.spring.io/libs-release" }
        maven { url "http://repo.spring.io/libs-snapshot" }
        mavenCentral()
        mavenLocal()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'war'
apply plugin: 'java'

apply plugin: 'application'

war {
    archiveName 'hello-gradle.war'
}

configurations {
    providedRuntime
}

compileJava {
    targetCompatibility = 1.8
    sourceCompatibility = 1.8
}

mainClassName = "XXX.Application"

    mavenCentral()
    maven { url "http://repo.spring.io/libs-release" }
    maven { url "http://repo.spring.io/libs-snapshot" }
    maven { url "http://maven.springframework.org/milestone" }
}

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
    compile 'com.fasterxml.jackson.core:jackson-core:2.5.3'

    compile 'org.springframework.data:spring-data-mongodb:1.8.0.RELEASE'
    compile("org.springframework:spring-context-support")

    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.8'
}

这是我的 catalina.log：

                    connector.setScheme("https");

                    Http11NioProtocol proto = (Http11NioProtocol) connector
                            .getProtocolHandler();
                    proto.setSSLEnabled(true);

                    proto.setKeystoreFile(absoluteKeystoreFile);
                    proto.setKeystorePass(keystorePass);
                    proto.setKeystoreType("JKS");
                    proto.setKeyAlias("abcd"); 
                });
            }
        };
    }
}

错误在这一行：

     tomcat.addConnectorCustomizers(connector -> {
                connector.setPort(Integer.parseInt(serverPort));
                connector.setSecure(true);
                connector.setScheme("https");

我不明白 errorPageFilter 是如何转换为 TomcatEmbeddedServletContainerFactory 的？

有人知道我该如何解决这个错误吗？

编辑：

我也创建了一个简单的 SpringBoot 测试应用来演示这个错误，你可以在这里找到它：https://github.com/Winghin2517/testSpringBootTomcat

github repo 中只有两个类：

1. ContainerConfiguration - 攻击类所在的位置。
2. DemoApplication - 主要方法在这里

如果您注释掉 ContainerConfiguration 并构建一个 war 文件，然后将其上传到 tomcat 服务器，它可以完美运行。 如果您取消注释 ContainerConfiguration 并构建 war 文件并上传它，您将收到错误消息。

Answer 1

为什么要在外部容器上部署嵌入式 Tomcat？我有类似的问题，最终对我有用的是从项目依赖项中完全排除 tomcat starter。由于spring-boot-starter-tomcat 是spring-boot-starter-web 的依赖项，因此使用如下内容：

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

当然，删除显式导入 spring-boot-starter-tomcat 的行（即使在嵌入模式下也不需要）。

如果您希望您的应用能够以两种方式部署，您可能会遇到问题 - 在我的情况下，我不必担心这一点。

Answer 2

您正在尝试使用自定义程序自定义 SSL 连接。 如果您启动嵌入式 tomcat 服务器，这是 100% 合法的。所以流程如下：

• 你自定义tomcat设置
• 你启动服务器

来自EmbeddedServletContainerCustomizer的JavaDocs

用于自定义自动配置的嵌入式 servlet 的策略接口 容器。这种类型的任何 bean 都会得到一个回调 在容器本身启动之前的容器工厂，所以你 可以设置端口、地址、错误页面等。

相反，您无法在已经运行的 tomcat 上自定义任何这些内容。

想象一下，如果您可以选择更改已经运行的 tomcat 的端口/地址，只需向其部署一个 war 文件，您可能会面临什么样的安全问题。

如果你真的需要自定义 ssl 连接器，你需要深入研究 tomcat 的 xml 配置。
