java - Spring Boot 异常 : java. lang.NoSuchMethodError : StandardJarScanner. setJarScanFilter(Lorg/apache/tomcat/JarScanFilter;)V

Question

我能够为 Spring Boot 应用程序 (spring-boot-gradle-plugin:1.2.6.RELEASE) 成功构建 gradle，但是当我尝试运行时出现以下异常。我相信有人对此提出了类似的问题，但我应该能够根据入门指南使用 1.2.6.RELEASE 运行 Spring Boot - http://spring.io/guides/gs/spring-boot/

关于如何解决此错误的任何想法？

下面列出了我的build.gradle，后面是异常

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.6.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'

mainClassName = "com.avada.base.Application"

sourceCompatibility = 1.8
targetCompatibility = 1.8

sourceSets {
    main {
        java {
            srcDir 'src'
        }
    }
    test {
        java {
            srcDir 'test'
        }
    }
}

jar {
    baseName = 'IR360'
    version =  '6.0.0'
}

repositories {
    mavenCentral()
}

configurations {
    all*.exclude module : 'spring-boot-starter-logging'
}

dependencies {
    compile ('org.springframework.boot:spring-boot-starter-web')
    compile("org.springframework.boot:spring-boot-starter-actuator")
    testCompile("junit:junit")

    compile fileTree(dir: 'aux-lib', include: '*.jar')
    compile fileTree(dir: 'common/lib', include: '*.jar')
    compile fileTree(dir: 'WebContent/WEB-INF/lib', include: '*.jar')
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.7'
}

您的类路径中有旧的且不兼容的 Tomcat 版本。查看您的 build.gradle，它一定来自您的 fileTree 依赖项之一。您应该更新它们的配置，以确保类路径上唯一的 Tomcat 依赖项是由 spring-boot-starter-web 引入的。如果您不确定从哪里加载旧的 Tomcat 类，使用 -verbose:class 运行应用程序会告诉您。
