在WebSphere 9上运行Spring Boot应用程序

Question

I've a Spring Boot Application with main class:

@SpringBootApplication
public class MyApplication extends SpringBootServletInitializer{

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
        return application.sources(applicationClass);
    }

    private static Class<MyApplication > applicationClass = MyApplication .class;
}

With gradle.build :

version '1.0'
// dependencies for command line
buildscript {
    ext {
        springBootVersion = '1.4.3.RELEASE'
        dependencyManagementVersion = '0.6.0.RELEASE'
    }
    repositories {
        jcenter()
    }
    dependencies {
        classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"
        classpath "io.spring.gradle:dependency-management-plugin:${dependencyManagementVersion}"
    }
}

apply plugin: "io.spring.dependency-management"
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'war'
apply plugin: 'eclipse'
apply plugin: 'idea'

// JDK 8
sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8

repositories {
    jcenter()
}

ext {
    springCloudVersion = 'Brixton.SR4'
    springBootVersion = '1.4.3.RELEASE'
    swaggerVersion = '2.4.0'

    jsonPathVersion = '2.2.0'
    ehcacheVersion = '3.2.0'

}

dependencyManagement {
    imports {

        mavenBom "org.springframework.boot:spring-boot-starter-parent:${springBootVersion}"
    }

        }
    }
}

tasks.withType(JavaExec) {
    if (System.getProperty("DEBUG", 'false') == 'true') {
        jvmArgs '-Xdebug', '-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5006'
    }
}

dependencies {
    // https://mvnrepository.com/artifact/javax/javaee-api

}

war {
    archiveName = "${project.name}.war"
    manifest {
        attributes 'Main-Class': 'com..content.MyApplication'
    }
}

When I try to deploy the war file on WebSphere Application Server 9.0 Traditional, it starts but takes very long time. Without war file, server starts and stops very normally, but with application, server hangs.

Am I missing something?

Thank you for help!!

Answer 1

The startup delay is probably caused by CDI's implicit bean archive scanning. If you are not using CDI, you can disable implicit bean archives with com.ibm.ws.cdi.enableImplicitBeanArchives=false .

You can find a much more detailed explanation in this tech note:
