thymeleaf是springboot推荐的模板引擎。那么如何在springboot工程中配置呢？
在appliaction.properties中加入
spring.thymeleaf.cache=false
spring.thymeleaf.mode=html
在pom.xml中将starter-web替换
在src/main/resources下创建templates文件夹，里面存放模板文件。
例如 web.html
<!DOCTYPE html>
hello,
（注意html的html标签必须申明）
controller中
@RequestMapping(“/web”)
public String web(Map<String,Object> map) {
map.put(“username”,”Jack”);
return “web”;
}
需要输出转义的html
${..} --- OGNL 表达式
#{…}--- 输出properties文件中的
properties文件输出
和template中html同名的properties文件
比如在home.html中要输出 #{welcome}, 则需要一个home.properties文件，里面有一行 welcome=xxx
