servletContext.getResourceAsStream(this.path)在模块化应用程序上返回null

Question

我在模块化应用程序中使用Spring boot 2.2和primefaces 6.2。so添加了一个新模块，用于使用带有thymeleaf-spring5的模板发送邮件。我的发送邮件模块它作为一个单一的应用程序运行得很好，但在我的原始项目上集成后，我有这个例外

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;
}

当我尝试发送邮件时，这是一个例外：

我不知道为什么，但我应该把我的templates文件夹放在/resources/META-INF/resources下才能工作！
