可执行的Spring Boot 2 jar

Question

我尝试安装我的Spring Boot应用程序.作为第一步,我尝试创建一个可执行jar,如下所述: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')
}

您已经链接到Spring Boot 1.x的参考文档,但是您正在使用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参考文档.

在该参考文档中,它描述了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.通过预先添加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()
}
