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
