使用freemarker和spring构造模板

要将发布的代码片段绑定在一起,可以执行以下操作:

// you already have this bit
String templateText = tempLoader.getTemplateForCurrentLogin();

// now programmatically instantiate a template
Template t = new Template("t", new StringReader(templateText), new Configuration());

// now use the Spring utility class to process it into a string
// myData is your data model
String output = FreeMarkerTemplateUtils.processTemplateIntoString(template, myData);

这个java方法将处理freemarker模板,并在构建模板后将html标记作为字符串。

public static String  processFreemarkerTemplate(String fileName) {

        StringWriter stringWriter = new StringWriter();
        Map<String, Object> objectMap = new HashMap<>();
        Configuration cfg = new Configuration(Configuration.VERSION_2_3_24);

        try {
            cfg.setDirectoryForTemplateLoading(new File("path/of/freemarker/template"));
            cfg.setDefaultEncoding("UTF-8");
            cfg.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);
            cfg.setLogTemplateExceptions(false);

            Template template = cfg.getTemplate(fileName);
            template.process(objectMap, stringWriter);

        } catch (IOException | TemplateException e) {
            e.printStackTrace();
        } finally {
            if (stringWriter != null) {
                try {
                    stringWriter.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return stringWriter.toString();
    }
