spring-boot - 使用在 META-INF/spring.factories 中找到的 Gradle-No 自动配置类

Question

尝试部署一个 jar，我使用 IntelliJ 中 gradle 中的 jar 函数在我的 spring

应用程序启动失败
org.springframework.beans.factory.BeanDefinitionStoreException:无法处理配置类 [haughton.icecreamapi.config.AppConfig] 的导入候选；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)}
}
}

我认为你应该让 spring-boot 插件来创建可执行的 jar(不要自己写)。默认情况下，此插件将搜索 public static void main(String[])任务类路径上的目录中的方法。如果要指定自己使用 bootJar 任务。

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