如何 运行 spring-boot embedded tomcat with tiles in eclipse？

Question

我有一个 spring-boot 应用程序打包为可执行 warfile，支持嵌入式 tomcat 与 spring mvc、jsp 和 tiles。

在 shell 中使用 java -jar app.war 启动构建的 Web 应用程序时，我成功获得了服务 运行ning。相反，当我尝试 运行 eclipse 中的启动配置时，sprint-boot 无法完成 tile 的初始化，但出现以下异常：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tilesConfigurer' defined in class path resource [au/com/inspiredgroup/config/MvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No URL for class path resource [WEB-INF/tiles.xml]

这是 MVC 配置：

@EnableWebMvc
@Configuration
public class MvcConfiguration extends WebMvcConfigurerAdapter {

    /**
     * Basic setup for JSP views.
     */
    @Bean(name = "viewResolver")
    public InternalResourceViewResolver configureInternalViewResolver() {
        final InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix(PREFIX);
        resolver.setSuffix(SUFFIX);
        resolver.setOrder(1);
        return resolver;
    }

    @Bean
    public TilesViewResolver tilesViewResolver() {
        final TilesViewResolver tilesViewResolver = new TilesViewResolver();
        tilesViewResolver.setOrder(0);
        return tilesViewResolver;
    }

    @Bean
    public TilesConfigurer tilesConfigurer() {
        final TilesConfigurer configurer = new TilesConfigurer();
        configurer.setDefinitions(new String[] { "classpath:/WEB-INF/tiles.xml" });
        return configurer;
    }
    [...]
}

eclipse 中的启动器配置为普通 Java 应用程序。

这发生在一个导入的项目中，它的 eclipse 设置没有在源代码控制存储库中共享（理解，在我看来，这通常是明智的（不是））；可能是因为这个原因，也可能不是，无论如何使用 maven 原型创建新项目不会重现问题。

为了修复我在 eclipse 中的设置，我必须编辑启动配置（对于 运行 作为 Java Application），进入类路径选项卡，然后单击“高级...”按钮，然后 'Add folder' 并导航以添加 /src/main/webapp 文件夹。它将添加到 'User Entries'。
