1. Add freemarker maven
<!-- freemarker -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
2. Configure freemarker in the application.yml file
application.yml compared to application.properties, in fact, the effect is the same, but using yml looks more clear, it is recommended to use
#------------------------freemarker-----------------------------
spring:
freemarker:
cache: false
suffix: .ftl
template-loader-path: classpath:/templates
content-type: text/html; charset=utf-8
settings:
number_format: 0 #数字格式，比较大的数字会带有逗号，如1,000
3. Front-end and background code testing
The author writes a simple controller here for testing
@RequestMapping(value = "/")
public String initItblog(Model model) {
model.addAttribute("msg", "hello");
return "login";
}
The front-end page should be careful. Because of some small problems with freemarker, if msg is empty, an error will be reported.
<html>
<head>
<title>login</title>
</head>
<body>
<#if (msg)!="">
${msg}
</#if>
</body>
</html>
