servletContext.getResourceAsStream(this.path) 在模塊化應用程序上返回 null

Question

我在模塊化應用程序中使用Spring boot 2.2和primefaces 6.2 。因此添加了一個新模塊以使用帶有thymeleaf-spring5模板發送郵件。 我的發送郵件模塊作為單體應用程序運行良好，但在我的原始項目集成后出現此異常，

我的配置：

@Bean
    public SpringResourceTemplateResolver htmlTemplateResolver(){
        SpringResourceTemplateResolver emailTemplateResolver = new SpringResourceTemplateResolver();
        emailTemplateResolver.setPrefix("/templates/");
        emailTemplateResolver.setSuffix(".html");
        emailTemplateResolver.setTemplateMode(TemplateMode.HTML);
        emailTemplateResolver.setCharacterEncoding(StandardCharsets.UTF_8.name());
        return emailTemplateResolver;
    }

這是我嘗試發送郵件時的異常：

好吧，我不知道為什么，但我應該將我的templates文件夾放在/resources/META-INF/resources下才能工作！
