如何读取的src / main / resources文件夹Freemarker模板文件？

Question

如何访问我的freemarker模板（* .ftl）文件从我的代码（春季启动应用程序）存储在我的src / main /资源文件夹中？

我尝试以下

freemarker.template.Configuration config = new Configuration();
configuration.setClassForTemplateLoading(this.getClass(), "/resources/templates/");

并且收到以下异常

freemarker.template.TemplateNotFoundException: Template not found for name "my-template.ftl".

Answer 1

类路径的根是src/main/resources，改变路径

configuration.setClassForTemplateLoading(this.getClass(), "/templates/");

Answer 2

我正面临“freemarker.template.TemplateNotFoundException：找不到名称模板...”的问题。我的代码是正确的，但我忘了，包括在pom.xml中/模板/目录。所以，下面的代码固定我的问题。我希望这有帮助。

 AppConfig.java :

    @Bean(name="freemarkerConfiguration")
    public freemarker.template.Configuration getFreeMarkerConfiguration() {
        freemarker.template.Configuration config = new freemarker.template.Configuration(freemarker.template.Configuration.getVersion());
        config.setClassForTemplateLoading(this.getClass(), "/templates/");
        return config;
    }

 EmailSenderServiceImpl.java:

    @Service("emailService")
    public class EmailSenderServiceImpl implements EmailSenderService 
    {
        @Autowired
        private Configuration freemarkerConfiguration;

        public String geFreeMarkerTemplateContent(Map<String, Object> dataModel, String templateName)
        {
            StringBuffer content = new StringBuffer();
            try {
                content.append(FreeMarkerTemplateUtils.processTemplateIntoString(freemarkerConfiguration.getTemplate(templateName), dataModel));
                return content.toString();
            }
            catch(Exception exception) {
                logger.error("Exception occured while processing freeMarker template: {} ", exception.getMessage(), exception);
            }
            return "";
        }
    }
