spring boot: thymeleaf模板引擎使用

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
