Spring Boot + Tomcat + Jetty-응용 프로그램을 시작하지 못했습니다.

Spring Boot + Tomcat + Jetty-응용 프로그램을 시작하지 못했습니다.

1. 질문(문제점):

Spring Boot + Java 8을 사용하고 있습니다. REST 리소스를 추가하고 기본 구성이 올바른지 테스트하려고합니다.

하지만 Spring Boot 애플리케이션을 시작하는 동안 문제가 발생했습니다. 아래 로그를 찾으십시오.

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.apache.catalina.startup.Tomcat.<init>(Tomcat.java:183)

The following method did not exist:

    org.apache.tomcat.util.ExceptionUtils.preload()V

The method's class, org.apache.tomcat.util.ExceptionUtils, is available from the following locations:

    jar:file:/home/xyz/.gradle/caches/modules-2/files-2.1/org.eclipse.jetty/jetty-runner/9.3.20.v20170531/56d1d067b4e42a6c603ece754534f9a65211924a/jetty-runner-9.3.20.v20170531.jar!/org/apache/tomcat/util/ExceptionUtils.class
    jar:file:/home/xyz/.gradle/caches/modules-2/files-2.1/org.apache.tomcat.embed/tomcat-embed-core/9.0.41/a43e9711e85073187d04b137882b4b7957180ef0/tomcat-embed-core-9.0.41.jar!/org/apache/tomcat/util/ExceptionUtils.class

The class hierarchy was loaded from the following locations:

    org.apache.tomcat.util.ExceptionUtils: file:/home/xyz/.gradle/caches/modules-2/files-2.1/org.eclipse.jetty/jetty-runner/9.3.20.v20170531/56d1d067b4e42a6c603ece754534f9a65211924a/jetty-runner-9.3.20.v20170531.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.apache.tomcat.util.ExceptionUtils

나는 바람둥이를 제외하려고 시도했지만 여전히 같은 문제가 발생했습니다.

아래 내 Gradle 설정을 살펴보십시오.

plugins {
    id 'org.springframework.boot' version '2.4.1'
    id 'io.spring.dependency-management' version '1.0.10.RELEASE'
    id 'java'
}

group = 'com.hive'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
targetCompatibility = '1.8'

configurations {
    all*.exclude module: 'log4j'
    all*.exclude module: 'log4j-core'
    all*.exclude module: 'slf4j-log4j12'
    all*.exclude module: 'log4j-slf4j-impl'
}

repositories {
    mavenCentral()
}

dependencies {

    compile group: 'org.apache.commons', name: 'commons-dbcp2', version: '2.7.0'
    compile group: 'org.apache.hive', name: 'hive-jdbc', version: '3.1.2'

    compile group: 'org.springframework.boot', name: 'spring-boot-starter-web'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-jdbc'

    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

위의 의존성 문제를 해결하기 위해 몇 가지 해결책을 제안하십시오.

2. 해결방안:

문제는 의존성 충돌이 발생한 jetty-runner를 다운로드하는 hive-jdbc 드라이버에 있습니다.

hive-jdbc에서 jetty-runner를 제외하면 위의 충돌 문제가 해결되었습니다.

    compile(group: 'org.apache.hive', name: 'hive-jdbc', version: '3.1.2') {
        exclude(group: 'org.eclipse.jetty', module: 'jetty-runner')
    }
