关于thymeleaf的相关配置

########################################################
###THYMELEAF (ThymeleafAutoConfiguration)
########################################################
#spring.thymeleaf.prefix=classpath:/templates/
#spring.thymeleaf.suffix=.html
#spring.thymeleaf.mode=HTML5
#spring.thymeleaf.encoding=UTF-8
# ;charset=<encoding> is added
#spring.thymeleaf.content-type=text/html 
# set to false for hot refresh 开发时设置不用缓存，生产环境设置为true
spring.thymeleaf.cache=false

开始使用：

编写模板文件 ：默认都放在  src/main/resouces/templates文件夹下

　　　　　　　　例如：src/main/resouces/templates/hello.html

示例代码： 

 

package com.mt.controller;

import java.util.Date;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/thymeleaf")
public class ThymeleafController {
    @RequestMapping("/hello")
    public String hello(Map<String, Object> map) {
        map.put("date", new Date());
        return "thymeleafDemo";
    }
}
