1、pom.xml 注入模板引擎thymeleaf依赖，切换thymeleaf版本为3.0
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
<!-- 布局功能的支持程序thymeleaf3主程序 layout2以上版本-->
<!-- thymeleaf2 layoout1-->
<thymeleaf-layout-dialect.version>2.1.1</thymeleaf-layout-dialect.version>
</properties>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
2、thymeleaf语法
@Controller
public class HelloController {
@ResponseBody
@RequestMapping("/hello")
public String hello(){
return "Hello World";
}
@RequestMapping("/success")
public String success(){
// classpath:/templates/success.html
return "success";
}
}
给sucess.html中设置内容
@Controller
public class HelloController {
@ResponseBody
@RequestMapping("/hello")
public String hello(){
return "Hello World";
}
@RequestMapping("/success")
public String success(Map<String,Object> map){
// classpath:/templates/success.html
map.put("hello","你好");
return "success";
}
}
<!DOCTYPE html>
<!--导入thymeleaf语法提示-->
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">

</head>
<body>
<h1>success!!!!!!!</h1>
<!--th:text 改变当前元素里面的文本内容-->
