[Spring Boot]使用Thymeleaf3

• gradle配置
  不需要配置spring boot默认的

compile('org.springframework.boot:spring-boot-starter-thymeleaf')

只需要添加

compile("org.thymeleaf:thymeleaf:3.0.2.RELEASE")
compile("org.thymeleaf:thymeleaf-spring4:3.0.2.RELEASE")
compile("nz.net.ultraq.thymeleaf:thymeleaf-layout-dialect:2.1.1")

• maven配置
  这个就更简单了,添加spring-boot-starter-thymeleaf，然后再配置版本号

    3.0.2.RELEASE
    2.0.4

使用Thymeleaf3的新功能css和js模板

        resolver.setViewNames(array("*.js"));
        resolver.setCache(false);
        return resolver;
    }
}

上面直接提供了现成的代码，然后再yml文件里面把缓存和默认的thymeleaf关了

spring:
  thymeleaf:
    cache: false
    enabled: false

完成了。下面给一个示例：
resources/templates/index.html

  
    
    
    
    
  
  
    
User hobbies
    

      

        Cinema
      
    
  Show secret code
  

  

resources/templates/main.css

body {
    font-family: Arial, sans-serif;
    padding-left: 1em;
    background-color: /*[[${backgroundColor}]]*/ pink;
}

resources/templates/common.js

function showCode() {
    var code = /*[[${code}]]*/ '12345';
    document.getElementById('code').innerHTML = code;
}
