Question

尝试在我的spring boot上使用我在IDE中的gradle中使用jar函数构建一个jar。它使用“bootrun”在我的IDE本地运行良好，但是没有在linux服务器上放一个jar。服务器上的完全错误是

应用程序启动失败 org.springframework.beans.factory.BeanDefinitionStoreException：无法处理配置类的导入候选[haughton.icecreamapi.config.AppConfig];嵌套异常是java.lang.IllegalArgumentException：在META-INF / spring.factories中找不到自动配置类。如果您使用的是自定义包装，请确保该文件正确无误。

我的build.gradle

group 'IceCreamApiCA1'
version '1.0-SNAPSHOT'
buildscript {

ext {
    springBootVersion = '1.5.9.RELEASE'
}
repositories{
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-
 plugin:${springBootVersion}")    }
 }

 // Apply the Spring Boot plugin
 //apply plugin: 'spring-boot'
 apply plugin: 'org.springframework.boot'
 // Apply the Java plugin (expects src/main/java to be source folder)
 apply plugin: 'java'

  // Specify the location where our dependencies will be found
repositories {
mavenCentral()
maven {
    url "http://repo.spring.io/milestone/"
}
}
jar{
baseName='IceCreamRestApi'
version='1.0.0'
manifest{
    attributes 'Main-Class': 'haughton.icecreamapi.Application'
}
from{
    configurations.compile.collect{ it.isDirectory() ? it : zipTree(it)}
}
}

 // Specify dependencies
dependencies {
compile 'org.hashids:hashids:1.0.1'

 }

我认为你应该让spring-boot插件创建可执行jar（不要自己编写）。默认情况下，此插件将在任务类路径的目录中搜索public static void main(String[])方法。如果要指定自己使用bootJar任务。

bootJar {
    mainClassName = 'com.example.ExampleApplication'
}

使用META-INF / spring.factories
