内容图文

我正在尝试将一个简单的Spring Boot应用程序转换为war文件,以部署到我的tomcat服务器,但是我一直在遇到此错误：

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

当我将其作为jar运行时,此Spring Boot应用程序可完美运行,但如果进行战争,则会出现错误.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: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'application'

war {
    archiveName 'hello-gradle.war'
}

configurations {
    providedRuntime
}

compileJava {
    targetCompatibility = 1.8
    sourceCompatibility = 1.8
}

mainClassName = "XXX.Application"

repositories {
    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.boot:spring-boot-starter-web'
    compile 'org.springframework.boot:spring-boot-starter-tomcat'
    compile 'org.springframework.boot:spring-boot-starter-security'
    compile 'org.springframework.boot:spring-boot-starter-actuator'
    compile 'org.springframework.boot:spring-boot-starter-aop'

    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：

它确实说该错误发生在我的名为ContainerConfiguration.java的Java文件中：

@Configuration

            @Value("${server.port}") final String serverPort,
            @Value("${keystore.pass}") final String keystorePass)
            throws Exception {

        // This is boiler plate code to setup https on embedded Tomcat
        // with Spring Boot:

        final String absoluteKeystoreFile = new File(keystoreFile)
                .getAbsolutePath();

        return new EmbeddedServletContainerCustomizer() {
            @Override
            public void customize(ConfigurableEmbeddedServletContainer container) {

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

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

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

错误在此行上：

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

我不知道如何将errorPageFilter强制转换为TomcatEmbeddedServletContainerFactory？

有谁知道我该如何解决这个错误？

编辑：

我还创建了一个简单的SpringBoot测试应用程序来演示此错误,您也可以在这里找到它：https://github.com/Winghin2517/testSpringBootTomcat

github存储库中只有两个类：

> ContainerConfiguration-攻击性类所在的位置.
> DemoApplication-主要方法坐在这里

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,则它可以完美运行.
如果取消注释ContainerConfiguration并构建war文件并上传它,则会收到错误消息.

解决方法:

您正在尝试使用定制程序定制SSL连接.
如果要启动嵌入式tomcat服务器,则100％合法.因此,流程如下：

>您自定义tomcat设置
>您启动服务器

来自EmbeddedServletContainerCustomizer的JavaDocs

Strategy interface for customizing auto-configured embedded servlet
containers. Any beans of this type will get a callback with the
container factory before the container itself is started, so you
can set the port, address, error pages etc.

相反,您无法在已经运行的tomcat上自定义其中任何一项.

想象一下,如果仅通过部署war文件就可以更改已经运行过的tomcat的端口/地址,则可能会遇到什么样的安全问题.

如果您确实需要自定义ssl连接器,则需要深入了解tomcat的xml配置.

可以找到一个很好的简单指南here
