在基于 JHipster 的 Web 应用程序中，无法运行从 Gradle BootRepackage 生成的 war

Question

我正在尝试运行使用 java -jar ./gradlew -Pprod bootRepackage 生成的 war 文件。 bootRepackage 任务成功结束。

当我查看 project_root/build/libs/ 文件夹时，war 和 war.original 文件是使用以下权限创建的：

-rw-rw-r-- 1 user user 110376521 Apr 24 09:42 app-0.1-SNAPSHOT.war
-rw-rw-r-- 1 user user 107542786 Apr 24 09:40 app-0.1-SNAPSHOT.war.original

在我的 build.gradle 中，我有以下内容：

apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'spring-boot'
apply plugin: 'war'

bootRepackage {
    mainClass = 'org.package.Application'
}

// Original from JHipster. Uncommenting this does not work either.
//springBoot {
//    mainClass = 'org.package.Application'
//}

// I got this from [this][1] questions, but did not work either.
war {
    baseName = 'app'
    version =  '0.1-SNAPSHOT'
    manifest {
        attributes 'Main-Class': 'org.package.Application'
    }
}

当我运行我得到的罐子时：

$ java -jar app-0.1-SNAPSHOT.war --spring.profiles.active=prod
java.lang.IllegalStateException: No 'Start-Class' manifest entry specified in jar:file:/home/user/.../build/libs/app-0.1-SNAPSHOT.war!/
        at org.springframework.boot.loader.archive.Archive.getMainClass(Archive.java:57)
        at org.springframework.boot.loader.ExecutableArchiveLauncher.getMainClass(ExecutableArchiveLauncher.java:63)
        at org.springframework.boot.loader.Launcher.launch(Launcher.java:61)
        at org.springframework.boot.loader.WarLauncher.main(WarLauncher.java:80)

我该怎么办？谢谢。

更新我解压缩了 war 并查看了 MANIFEST.MF:

Manifest-Version: 1.0
Start-Class: org.package.Application
Spring-Boot-Version: 1.1.7.RELEASE
Main-Class: org.springframework.boot.loader.WarLauncher

我这样说对吗？

Answer 1

这是有效的 build.gradle，bootRepackage 注释掉了：

buildscript {
    repositories {
        mavenCentral()
                        }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.3.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'spring-boot'
apply plugin: 'war'

repositories {
    mavenCentral()
}


dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
}

//bootRepackage {
//    mainClass = 'org.package.Application'
//    }

war {
    baseName = 'app'
    version =  '0.1-SNAPSHOT'
    manifest {
        attributes 'Main-Class': 'org.package.Application'
    }
}

差异 MANIFEST.INF

> libs  diff META-INF/MANIFEST.MF ~/temp/MANIFEST-MF-works 
2c2
< Start-Class: org.package.Application
---
> Start-Class: Application

在行动

> sample        /opt/java/bin/java -jar build/libs/app-0.1-SNAPSHOT.war
