java - 将 Spring Boot 应用程序部署到 Websphere 8.5.5.8

Question

我正在尝试将一个非常基本的 spring boot 应用程序部署到 Websphere 8.5.5.8(使用 IBM J6 VM，在 Java 1.6.0 上)。相同的应用程序适用于 Glassfish，但在 Websphere 上抛出异常。我一直在尝试按照网上的每一个指南来让它工作，但仍然无济于事，有人可以阐明我的错误吗？

异常日志如下:

最后是我的主课:

@SpringBootApplication(exclude = MessageSourceAutoConfiguration.class)
public class ServletInitializer extends SpringBootServletInitializer {

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

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

Answer 1

这里的问题看起来像你的 ServletInitializer类是使用与运行 WebSphere 不同的版本编译的。根据this table , WAS 8.5.5.8 随 Java 68 一起提供。

看看你的 pom.xml，你有你的 ServletInitializer使用 Java 7 构建:

<properties>
    <start-class>com.test.ServletInitializer</start-class>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.7</java.version>
</properties>

所以将其降低到 <java.version>1.6</java.version>希望这能解决您的问题。

旁注:
您在 Java EE 7 的 pom.xml 中有一个依赖项，但 WebSphere 传统版在 9.0 版之前不兼容 EE7，因此我建议您提高 javaee-api版本降至 6.0 .
