Spring Boot学习（六）

模板引擎

Spring Boot可以完美的实现动态HTML，Spring Boot提供了多种模板引擎。

  • Thymeleaf
  • FreeMarker
  • Velocity
  • Mustache
  • Groovy

 Spring Boot推荐使用Thymeleaf模板引擎，原因在于它提供了完美的Spring MVC支持。

一、Thymeleaf基础知识

Thymeleaf是一个XML/XHTML/HTML5模板引擎，可用于Web与非Web环境中的应用开发，是一个java类库。可以使用它完全替代View层。

二、示例

导入Thymeleaf依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

编写Controller

@Controller
public class HelloController {


    @GetMapping("hello")
    public String getHello(ModelMap modelMap){
        modelMap.addAttribute("name","Thymeleaf");
        return "index";
    }
}

在默认的模板路径src/main/resources/templates下编写模板文件

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org" >
<head>
    <meta charset="UTF-8">
    <title>Thymeleaf示例</title>
</head>
<body>
    <h1 th:text="${name}">Hello World</h1>
</body>
</html>

（

xmlns:th="http://www.thymeleaf.org"：命名空间，需要进行动态处理的元素将使用"th:"为前缀。

）

启动程序后，访问http://localhost:8080/，则是展示Controller中name的值：Thymeleaf

三、Thymeleaf的默认参数配置

# Enable template caching.
spring.thymeleaf.cache=true 
# Check that the templates location exists.
spring.thymeleaf.check-template-location=true 
# Content-Type value.
spring.thymeleaf.content-type=text/html 
# Enable MVC Thymeleaf view resolution.
spring.thymeleaf.enabled=true 
# Template encoding.
spring.thymeleaf.encoding=UTF-8 
# Comma-separated list of view names that should be excluded from resolution.
spring.thymeleaf.excluded-view-names= 
# Template mode to be applied to templates. See also StandardTemplateModeHandlers.
spring.thymeleaf.mode=HTML5 
# Prefix that gets prepended to view names when building a URL.
spring.thymeleaf.prefix=classpath:/templates/ 
# Suffix that gets appended to view names when building a URL.
spring.thymeleaf.suffix=.html  spring.thymeleaf.template-resolver-order= # Order of the template resolver in the chain. spring.thymeleaf.view-names= # Comma-separated list of view names that can be resolved.
