Spring 应用程序上的 NoClassDefFoundError

Question

此图像中存在完整错误，因为我运行在通过视频源访问的云端虚拟机上，所以我无法复制 paste.This 是 ubuntu 的全新安装我只安装了 JDK 而没有其他任何东西不知道是否需要完成其他设置 https://imgur.com/a/egJ3d

它是一个 spring 启动应用程序。我的 build.gradle

group 'com.haughon.daniel'
version '1.0-SNAPSHOT'



buildscript {
repositories{
    mavenCentral()
}
dependencies {
    classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE'
}
}

// Apply the Spring Boot plugin
apply plugin: 'spring-boot'

 // Apply the Java plugin (expects src/main/java to be source folder)
 apply plugin: 'java'
apply plugin: 'idea'

 // Specify the location where our dependencies will be found
repositories {
mavenCentral()
}
jar {
   manifest {
    attributes 'Main-Class': 'haughton.dvdstore.Application'
    attributes 'addClasspath': 'true'

}
}

 // Specify dependencies
  dependencies {

compile 'org.hashids:hashids:1.0.1'
compile 'org.springframework.boot:spring-boot-starter-thymeleaf'
compile 'org.springframework:spring-orm:4.3.7.RELEASE'
compile 'org.hibernate:hibernate-core:5.2.9.Final'
compile 'org.hibernate:hibernate-entitymanager:5.0.6.Final'
compile 'org.apache.tomcat:tomcat-dbcp:8.0.30'
compile 'org.springframework.boot:spring-boot-starter-security'
compile('org.thymeleaf.extras:thymeleaf-extras-springsecurity4')
//compile 'org.thymeleaf.extras:thymeleaf-extras-springsecurity:3.0.2.RELEASE'
compile group: 'org.springframework.data', name: 'spring-data-jpa', version: '1.11.1.RELEASE'
// https://mvnrepository.com/artifact/com.google.code.gson/gson
compile group: 'com.google.code.gson', name: 'gson', version: '2.8.0'
// https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core
compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.8.8'

runtime 'com.h2database:h2'
runtime 'javax.transaction:jta:1.1'
runtime 'org.aspectj:aspectjweaver:1.8.7'
testCompile 'org.springframework.boot:spring-boot-starter-test'
}

Answer 1

这是因为你的依赖没有包含在一个jar文件中。

使用./gradlew clean build
