spring boot: thymeleaf模板引擎使用

在pom.xml加入thymeleaf模板依赖

<!-- 添加thymeleaf的依赖 -->

  <dependency>

      <groupId>org.springframework.boot</groupId>

      <artifactId>spring-boot-starter-thymeleaf</artifactId>

  </dependency>

　　

在applicationContext.properties中增加thymeleaf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

spring.thymeleaf.cache=false

　　

#<!-- 关闭thymeleaf缓存 开发时使用 否则没有实时画面-->

spring.thymeleaf.cache=false

## 检查模板是否存在，然后再呈现

spring.thymeleaf.check-template-location=true

#Content-Type值

spring.thymeleaf.content-type=text/html

#启用MVC Thymeleaf视图分辨率

spring.thymeleaf.enabled=true

## 应该从解决方案中排除的视图名称的逗号分隔列表

##spring.thymeleaf.excluded-view-names=

#模板编码

spring.thymeleaf.mode=LEGACYHTML5

# 在构建URL时预先查看名称的前缀

spring.thymeleaf.prefix=classpath:/templates/

# 构建URL时附加查看名称的后缀.

spring.thymeleaf.suffix=.html

# 链中模板解析器的顺序

#spring.thymeleaf.template-resolver-order= o

# 可以解析的视图名称的逗号分隔列表

#spring.thymeleaf.view-names=

#thymeleaf end
