可执行的Spring Boot 2 jar

提问于

我尝试安装我的Spring Boot应用程序 . 作为第一步,我尝试创建一个如下所述的可执行jar:https://docs.spring.io/spring-boot/docs/current/reference/html/deployment-install.html

但是,如果我使用以下行扩展我的gradle脚本(我正在使用gradle 4.4):

springBoot {
    executable = true
}

然后构建失败并出现错误:

FAILURE: Build failed with an exception.

* Where:
Build file 'D:\spring\app\build.gradle' line: 15

* What went wrong:
A problem occurred evaluating root project 'app'.
> Could not find method springBoot() for arguments [build_3mwux4us8m2jn9yfcogqkbm4y$_run_closure1@506b241f] on root project 'app' of type org.gradle.api.Project.

我的构建脚本如下:

buildscript {
    ext {
        springBootVersion = '2.0.0.M6'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

springBoot {
    executable = true
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'


group = 'com.test'
version = '0.0.3'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
    maven { url 'https://repo.spring.io/libs-release' }
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    compile('org.springframework.boot:spring-boot-starter-validation')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.data:spring-data-envers:2.0.2.RELEASE')
    compile('nz.net.ultraq.thymeleaf:thymeleaf-layout-dialect')
    compile("org.thymeleaf.extras:thymeleaf-extras-springsecurity4")
    runtime('org.springframework.boot:spring-boot-devtools')
    runtime('mysql:mysql-connector-java')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.security:spring-security-test')
}

    你've linked to the reference documentation for Spring Boot 1.x, but you'使用Spring Boot 2.x,其中Gradle插件已经被广泛更新 . 它现在有自己独立的reference documentation .

    在该参考文档中,describes如何创建包含前置启动脚本的完全可执行jar文件:

    Spring Boot为完全可执行的归档提供支持 . 通过预先知道如何启动应用程序的shell脚本,可以使归档完全可执行 . 在类Unix平台上,此启动脚本允许存档像任何其他可执行文件一样直接运行或作为服务安装 . 要使用此功能,必须启用包含启动脚本:bootJar {
    launchScript()
    }

    尝试手动执行以下gradle任务:

    gradlew jar gradlew bootRepackage

    之后你应该有你的捆绑脂肪 jar . (多数民众赞成我是如何解决的)
