【问题描述】：
我为 Spring boot 和 Thymeleaf 创建了简单的演示，但我无法打开索引页面。
控制器代码：
package com.jrp.demo.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping(value = "/")
public String home() {
return "index";
}
}
在/src/main/resources/templates/index.html中有索引模板
拥有application.properties：
server.port=9095
然后转到地址http://localhost:9095/
得到错误：

Spring boot 类是：
package com.jrp.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
并且 pom.xml 包含 spring-boot-starter-thymeleaf 和 spring-boot-starter-web。
【问题讨论】：
-
你能给我看看你的
index.html和application.properties -
您的资源也打包正确了吗？检查
target文件夹的内容。如果 html 模板在您的控制器中的路径下不存在 - 尝试清理重建您的应用程序并考虑检查您的Maven Resources插件（如果您使用它） -
@FaeemazazBhanej
application.properties有问题描述（只有server.port存在）并且index.html仅包含<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>This is index page</h1> </body> </html> -
@PavelPolyakoff 我在项目上运行了
clean install并在目标中寻找index.html并在路径..\demo1\target\demo-0.0.1-SNAPSHOT.jar\BOOT-INF\classes\templates` but have not found it directly intarget 上找到它，是不是错了？附：目前项目中没有配置maven资源插件。 -
您能否展示一下您的 MVC 配置类？您配置了
template resolverbean 的那个。通常它是一个实现WebMvcConfigurer的@Configuration类。如果您没有创建它 - 您的 Spring 可能不知道您的控制器方法的返回是模板的路径
