在Liberty服务器上运行spring-boot应用

Question

我开发了一个服务于rest服务的独立spring boot应用程序，我把它打包成了一个< code>jar，它运行正常。为了在生产服务器(Websphere)上发布它，我必须将它转换成一个< code>war。

我已经更新了我的＜code＞pom。xml添加以下行：

<properties>
    <maven.compiler.target>1.7</maven.compiler.target>
    <maven.compiler.source>1.7</maven.compiler.source>
</properties>
<packaging>war</packaging>
<build>
    <finalName>${artifactId}</finalName>
</build>

然后，我启动了maven净包，我得到了war。因此，在Tomcat服务器上发布它可以正常工作，但在Liberty上我收到了错误：

Error 404: SRVE0190E: File not found /

我还修改了我的入口点，如下所示：

@SpringBootApplication
@PropertySource("classpath:alerts.properties")
public class WebApplication extends SpringBootServletInitializer 
{

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

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

没有成功，所以...如何在Liberty服务器上运行Spring启动战？

更新

正如@Anjum Fatima所建议的，我还添加了server.xml中的功能。

<feature>jsp-2.3</feature>
<feature>springBoot-2.0</feature>
<feature>servlet-3.1</feature>

之前，在该文件中，我还添加了：

<library>
    <file id="alerts.properties" name="${shared.resource.dir}/alerts.properties"/>
</library>
<webApplication id="alerts" location="alerts.war" name="alerts">

在wlp18\usr\shared\resources中，我复制了属性文件。

但是我还是有同样的错误。

alert.properties文件：

spring.datasource.url=jdbc:h2:file:~/alertsdb;DB_CLOSE_ON_EXIT=FALSE;AUTO_RECONNECT=TRUE
spring.datasource.username=admin
spring.datasource.password=mypassword
spring.datasource.driver-class-name=org.h2.Driver

spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

spring.h2.console.enabled=true
spring.h2.console.settings.web-allow-others=true

spring.mvc.view.prefix: /
spring.mvc.view.suffix: .jsp
spring.messages.basename=validation

更新2

服务器快启动了，但是找不到一些文件，比如com.ibm.ws.kernel.boot.nls_1.0.22.jar，在Liberty的lib文件夹中有文件com.ibm.ws.kernel.boot_1.0.22.jar（没有. nls）这是控制台输出，我缺少什么？

你不需要把Spring靴罐当作一场自由战争。以下是有关如何在自由中部署Spring Boot罐的自由指南：https://openliberty.io/guides/spring-boot.html 这里有另一篇关于在自由中运行Spring Boot应用程序的精彩文章：https://developer.ibm.com/articles/modernize-and-optimize-spring-boot-applications/

如果您将应用程序打包为一个真正的war，而不是一个转换的jar文件，那么您只需要servlet功能和dropins文件夹。

我的< code>server.xml:

<server description="Tester">
    <featureManager>
        <feature>servlet-4.0</feature>
    </featureManager>

    <httpEndpoint host="*" httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint"/>
</server>

当您在Maven中运行包目标时，它将创建一个war和一个jar，其中包含jar格式的自由运行时包。您可以将战争放在当前应用程序的下拉列表文件夹中。确保Liberty＜code＞消息中没有其他错误。日志文件。

您可以在https://github.com/anjumfatima90/dojo.samples.中查看一个示例Spring Boot war应用程序，它包含自由部署的步骤。我希望这能有所帮助。

更新：有两种方法可以在开放自由中部署Spring启动战争，您将其部署为普通的旧战争，不需要将springBoot-2.0功能添加到server.xml.我的github示例显示了另一种方法，您可以在server.xml中添加springBoot-2.0功能以及中的更改。

考虑到你的方式，它是作为一个普通的旧战争部署的。斯科特克隆了你的应用程序，并在他的存储库https://github.com/scottkurz/springboot-liberty-1中添加了自由-maven-plugin来帮助你。

工作步骤：

< li >使用< code > git Clone https://github . com/Scott Kurz/spring boot-liberty-1 . git 克隆存储库。 < li >运行< code>mvn全新安装 < li >运行< code>mvn liberty:运行 < li >您会发现在应用程序的目标文件夹中创建了一个< code>liberty文件夹。您可以将您的服务器与< code > target/liberty/WLP/usr/servers/default server 进行比较。

注意：Scott在应用程序的src/main/Resources中添加了alerts.properties。
