我尝试安装我的 Spring Boot 应用程序。
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 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')
}
您已链接到 Spring Boot 1.x 的参考文档,但您使用的是 Spring Boot 2.x,其中 Gradle 插件已进行了相当广泛的更新。现在它有自己的、独立的参考文档 https://docs.spring.io/spring-boot/docs/2.0.0.M6/gradle-plugin/reference/html.
在该参考文档中,它描述 https://docs.spring.io/spring-boot/docs/current-SNAPSHOT/gradle-plugin/reference/html/#packaging-executable-configuring-launch-script如何创建包含前置启动脚本的完全可执行的 jar 文件:
Spring Boot 提供对完全可执行档案的支持。通过预先添加知道如何启动应用程序的 shell 脚本,使存档完全可执行。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,必须启用启动脚本:
bootJar {
launchScript()
}
