java版b2b2c社交电商spring cloud分布式微服务(八)开发Web应用(2)

在完成配置之后,举一个简单的例子,在快速入门工程的基础上,举一个简单的示例来通过Thymeleaf渲染一个页面。

@Controller
public class HelloController {
 
    @RequestMapping("/")
    public String index(ModelMap map) {
        // 加入一个属性,用来在模板中读取
        map.addAttribute("host", "http://blog.didispace.com");
        // return模板文件的名称,对应src/main/resources/templates/index.html
        return "index";  
    }
 
}
<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8" />
    <title></title>
</head>
<body>
<h1 th:text="${host}">Hello World</h1>
</body>
</html>

如上页面,直接打开html页面展现Hello World,但是启动程序后,访问http://localhost:8080/,则是展示Controller中host的值:http://blog.didispace.com,做到了不破坏HTML自身内容的数据逻辑分离。

更多Thymeleaf的页面语法,还请访问Thymeleaf的官方文档查询使用。

Thymeleaf的默认参数配置

如有需要修改默认配置的时候,只需复制下面要修改的属性到application.properties中,并修改成需要的值,如修改模板文件的扩展名,修改默认的模板路径等。

# 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.

支持JSP的配置
Spring Boot并不建议使用,但如果一定要使用,可以参考此工程作为脚手架:jsp支持
