Bereitstellen einer Spring-Anwendung mit Tomcat-Gradle-Plugin

Question

Ich versuche, eine Feder-Anwendung auf Tomcat mit dem bmuschko tomcat-Plugin (https://github.com/bmuschko/gradle-tomcat-plugin) zu implementieren.

Ich habe eine index.jsp in meinem Webapp-Ordner, der korrekt angezeigt wird. Die Sache ist, dass meine Anwendung nicht bereitgestellt wird. (aber Tomcat funktioniert einwandfrei, da meine index.jsp korrekt angezeigt wird). Ich denke, es könnte mit der Tatsache zusammenhängen, dass es eine Frühlingsanwendung ist, aber ich habe keine Ahnung, wie ich das überwinden kann (ich bekomme keinen Fehler und bin mir nicht sicher, wo ich meinen Katalog finden kann).

Meine Klasse build.gradle:

buildscript { 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.3.RELEASE") 
    } 
} 

apply plugin: 'java' 
apply plugin: 'eclipse' 
apply plugin: 'idea' 
apply plugin: 'spring-boot' 
apply plugin: 'war' 
apply plugin: 'com.bmuschko.tomcat' 

jar { 
    baseName = 'gs-accessing-data-jpa' 
    version = '0.1.0' 
    manifest { 
     attributes 'Main-Class': 'tutorialDatabaseServer.Application' 
    } 
} 

repositories { 
    mavenCentral() 
    maven { 
     url "https://repository.jboss.org/nexus/content/repositories/releases" 
    } 
} 

sourceCompatibility = 1.8 
targetCompatibility = 1.8 

dependencies { 
    compile("org.springframework.boot:spring-boot-starter-data-jpa") 
    compile("org.postgresql:postgresql") 
    testCompile("junit:junit") 

    compile("org.springframework.boot:spring-boot-starter-web") 
    compile("org.springframework.boot:spring-boot-starter-actuator") 
    // compile("org.postgresql:postgresql:9.4-1201-jdbc41") 
    compile("com.fasterxml.jackson.core:jackson-databind") 
    compile("org.liquibase:liquibase-core:3.3.3") 
    compile("org.springframework.boot:spring-boot-starter-data-mongodb") 
    compile 'org.springframework.boot:spring-boot-starter-thymeleaf' 
    compile("org.springframework.boot:spring-boot-starter-web") 
    compile group: 'org.hibernate', name: 'hibernate-validator', version:'4.2.0.Final' 
    compile group: 'javax.el', name: 'el-api', version: '2.2.1-b04' 
    compile group: 'org.postgresql', name: 'postgresql', version: '9.4.1212' 

    def tomcatVersion = '8.5.16' 
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}", 
     "org.apache.tomcat.embed:tomcat-embed-logging-juli:8.5.2", 
     "org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}" 

} 

tomcat { 
    httpProtocol = 'org.apache.coyote.http11.Http11Nio2Protocol' 
    ajpProtocol = 'org.apache.coyote.ajp.AjpNio2Protocol' 
} 


task wrapper(type: Wrapper) { 
    gradleVersion = '2.3' 
} 

buildscript { 

    repositories { 
     jcenter() 
    } 

    dependencies { 
     classpath 'com.bmuschko:gradle-tomcat-plugin:2.3' 
    } 
} 

und meine Anwendung:

@SpringBootApplication 
public class Application { 

private static final Logger log = 
LoggerFactory.getLogger(Application.class); 

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

Vielen Dank.

EDIT: nach meiner Anwendungsklasse, wie vorgeschlagen, der Kater log ändert, ist die folgende:

Sie müssen SpringBootServletInitializer erweitern und außer Kraft setzen configure() -Methode als Kriegs-Datei bereitstellen, finden Sie spring boot docs.

@SpringBootApplication 
public class Application extends SpringBootServletInitializer { 

    private static final Logger log = LoggerFactory.getLogger(Application.class); 

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

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

} 

Edit:

Ihre build.gradle enthält inkompatible Protokollierung Abhängigkeiten. Beim Start lädt der Classloader keine slf4j-Klassen und wird mit java.lang.StackOverflowError beendet. Um es zu lösen, musste ich Build.gradle wie unten ändern.

buildscript { 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.4.RELEASE") 
     classpath 'com.bmuschko:gradle-tomcat-plugin:2.3' 
    } 
} 

apply plugin: 'java' 
apply plugin: 'eclipse' 
apply plugin: 'idea' 
apply plugin: 'spring-boot' 
apply plugin: 'war' 
apply plugin: 'com.bmuschko.tomcat' 

jar { 
    baseName = 'gs-accessing-data-jpa' 
    version = '0.1.0' 
    manifest { 
     attributes 'Main-Class': 'tutorialDatabaseServer.Application' 
    } 
} 

repositories { 
    mavenCentral() 
    maven { 
     url "https://repository.jboss.org/nexus/content/repositories/releases" 
    } 
} 

sourceCompatibility = 1.8 
targetCompatibility = 1.8 

dependencies { 
    compile('ch.qos.logback:logback-classic:1.2.3')

    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",

     ajpProtocol = 'org.apache.coyote.ajp.AjpNio2Protocol'
