问题

以下是翻译好的内容：

我有一个最初为内部Tomcat服务器构建的Spring Boot Web应用程序（正常工作）。
然后我将该应用程序调整为在Web Logic服务器上运行。
我的应用程序编译并且无问题地部署到服务器，但是当它不提供MVC页面时。
每个调用都会抛出404错误。
从下面的错误中看来，似乎Spring调度程序Servlet存在，但是甚至区域设置也没有设置正确。
我无法弄清楚这里出了什么问题或者缺少什么，但是当我创建RestController而不是MVC时，
它可以工作并且内容显示出来。该应用程序基于Spring Boot 2.3.2版本。

应用程序类：

@SpringBootApplication
@ComponentScan({"ie.gov.agriculture.alf", "ie.gov.agriculture.sso"})
public class AlfApplication extends SpringBootServletInitializer implements WebApplicationInitializer {

    public AlfApplication() {
        super();
        setRegisterErrorPageFilter(false); // 禁用ErrorPageFilter以避免烦人的错误消息
    }

    // 其他代码...
}

AppConfig类：

@Configuration
@EnableCaching
public class AppConfig {

    @Bean
    public ReloadableResourceBundleMessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("messages");
        return messageSource;
    }

    // 其他代码...
}

最后是WebMvcConfig类：

@Configuration
@ServletComponentScan
public class WebMvcConfig implements WebMvcConfigurer {

    @Bean
    public ViewResolver getViewResolver() {
        UrlBasedViewResolver resolver = new UrlBasedViewResolver();
        resolver.setPrefix("/WEB-INF/pages/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

    // 其他代码...
}

以上是您提供的内容的翻译版本，仅包括代码部分的翻译。

英文:

I have Spring Boot Web application initially built for internal Tomcat server (works).
Then I adopted that application to be run on Web Logic server.
My application compile and deploys to the server without issues but when it is not serving MVC pages.
Every call throws 404 error.
From the error below it looks like spring dispatcher servlet is present but even locale is not set properly.
I can't figure out what is wrong or missing here but when I create RestController instead of MVC it
works and contents shows up. Application is based on Sprint Boot 2.3.2

这个问题的答案一如既往地是一个简单的技巧，消息配置 bean 应该如下所示，一切都会正常工作，关键是在 setBasename 中使用 "classpath:"。

@Bean
public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:messages");
    return messageSource;
}

英文:

The answer to this problem is as always a simple trick, messages configuration bean should looks like this and everything work fine, the key is "classpath: " in setBasenema

@Bean
public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename(&quot;classpath:messages&quot;);
    return messageSource;
}
