1.创建模板引擎服务：

package com.ftvalue.customer.service;




import freemarker.cache.ClassTemplateLoader;
import freemarker.cache.TemplateLoader;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;
import org.springframework.ui.freemarker.FreeMarkerTemplateUtils;

import java.io.IOException;
import java.util.Map;

/**

public class TempleEngineService {

    public static String EmailTemplate(String templateName,Map model) throws IOException, TemplateException {
        Configuration configuration = new Configuration();

        TemplateLoader c1 = new ClassTemplateLoader(TemplateLoader.class,"/static/templates");

        configuration.setTemplateLoader(c1);


        Template template = configuration.getTemplate(templateName);

        String txt = FreeMarkerTemplateUtils.processTemplateIntoString(template,model);

        return txt;
    }
}

2.在接口方法中调用：

@Override
    public   String sendEmail(String mailTemplate,String mailTitle,String target,Map model) {
        String response = null;
        try{
            //引用模板引擎
            String txt = TempleEngineService.EmailTemplate(mailTemplate,model);
            Map<String,String> args = new HashMap<>();
            args.put("to",target);
            args.put("subject",URLEncoder.encode(mailTitle,"GBK"));
            args.put("charset","GBK");
            args.put("body",URLEncoder.encode(txt,"GBK"));
            log.info("args:"+args);
            response = HttpUtil.getResponseBody(args,ymlConfig.getIsmpEimsEmail());
        }catch (Exception e){
           log.error("邮件服务异常："+e.getMessage());
            try {
                throw new Exception("邮件服务异常");
            } catch (Exception e1) {
                e1.printStackTrace();
            }
        }
        return response;

    }
