spring-boot war在启动时失败(spring-boot war fails on startup)

 我正在尝试使用带有gretty的spring-boot创建一个Web服务。 在gradle中调用appStart时效果很好，但在调用appStartWar时会显示错误。  
 这是错误：

 它似乎找不到war文件中的主类，但com.example.server.Application确实存在于与WEB-INF/classes/com/example/server路径的战争中  
 的build.gradle  
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'spring-boot'
apply plugin: 'org.akhikhl.gretty'

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'org.akhikhl.gretty:gretty:1.1.8'
        classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.2.2.RELEASE'
    }
}

dependencies{

    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
    providedCompile 'javax.servlet:javax.servlet-api:3.1.0'

}

gretty {
    springBoot = true
    springBootVersion = '1.2.2.RELEASE'
    httpsEnabled = true
}
 
 Application.java  
@RestController
@SpringBootApplication
class Application extends SpringBootServletInitializer {

    public static void main( String[] args ) {
        SpringApplication.run( Application.class, args );
    }

    @Override
    protected SpringApplicationBuilder configure( SpringApplicationBuilder builder ) {
        return builder.sources( Application.class );
    }

    @RequestMapping( value = "test", method = RequestMethod.GET )
    public String test() {
        return "success";
    }


}
 
 任何帮助赞赏:)  
 
 这是我在Gitlab 链接中的项目  
 
 我试图直接将战争部署到tomcat-7，但它也失败了。 所以我认为这不是一个问题。

I am trying to make a web-service using spring-boot with gretty. It works well when calling appStart in gradle, but it would show error when calling appStartWar.

It seems that it could not find the main class in war file, but the com.example.server.Application really exists in war with path WEB-INF/classes/com/example/server

}

gretty {
    springBoot = true

}
 
Application.java

    }

    @RequestMapping( value = "test", method = RequestMethod.GET )
    public String test() {
        return "success";
    }


}
 
Any help appreciated :) 
 
Here's my project in Gitlab link 
 
I've tried to deploy war to tomcat-7 directly, but it failed as well. So I think this is not a gretty problem.

 我先对数组进行排序，然后循环遍历它，在下一个条目上执行Levenshtein（）函数。  
$rars = array(
    books.part1.rar,
    books.part3.rar,
    00000114.rar,
    svoy_20ostrov.rar,
    svoy_20ostrov.rar,
    koncert_20v_20dk_20mir.rar,
    koncert_20v_20centralnom_20teatre_20kukol.rar,
    LP_LIVE_PR_Tampa.part2.rar,
    koncert_20v_20dk_20vami.rar,
    koncert_20v_20dk_20kommuna_20chast1.rar,
    books.part2.rar,
    koncert_20v_20dk_20kommuna_20chast2.rar,
    books.part4.rar,
    recedivist.rar,
    LP_LIVE_PR_Tampa.part1.rar
)

sort($rars);
$current = 0;
$rars_complete = array();
foreach($rars as $i=>$rar) {
    $next = ($i + 1) < count($rars)) ? $i + 1 : false;
    $rars_complete[$current][] = $rar;
    if($next != false && levenshtein($rar, $rars[$next]) == 1)
        continue;
    else
        $current++;
}
 
 请注意，这未经过测试。 

I would sort the array first and then loop through it, performing the Levenshtein() function on the next entry. 
$rars = array(
    books.part1.rar,
    books.part3.rar,
    00000114.rar,
    svoy_20ostrov.rar,
    svoy_20ostrov.rar,
    koncert_20v_20dk_20mir.rar,
    koncert_20v_20centralnom_20teatre_20kukol.rar,
    LP_LIVE_PR_Tampa.part2.rar,
    koncert_20v_20dk_20vami.rar,
    koncert_20v_20dk_20kommuna_20chast1.rar,
    books.part2.rar,
    koncert_20v_20dk_20kommuna_20chast2.rar,
    books.part4.rar,
    recedivist.rar,
    LP_LIVE_PR_Tampa.part1.rar
)

sort($rars);
$current = 0;
$rars_complete = array();
foreach($rars as $i=>$rar) {
    $next = ($i + 1) < count($rars)) ? $i + 1 : false;
    $rars_complete[$current][] = $rar;
    if($next != false && levenshtein($rar, $rars[$next]) == 1)
        continue;
    else
        $current++;
}
 
Note, this is not tested.
