Question

我肯定在映射方面遇到问题，我在spring boot中创建了一个简单的应用程序，但是映射错误，这是我的代码：

package com.example.demo;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;


@SpringBootApplication
@ComponentScan(basePackages={"com.example"})
public class DemopApplication2 {

    public static void main(String[] args) {
        SpringApplication.run(DemopApplication2.class, args);
        System.out.println("erffffggggggggggggf");
    }

}


package com.example.demo.jjj;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Controller
@RequestMapping(value = "/hanoipp")
public class Omp {
    @RequestMapping("/smm")
    String welcome() {
        return "index";
    }
}

，我在模板中有一个简单的html文件，称为index.html，但这不起作用我的日志文件是：

静态html文件转到static，而不是template。

static中的所有内容都直接传递给客户端。

没有thymeleaf，您没有用于html文件的服务器端解析器。

template目录是经过解析的模板文件，它们产生客户端接收的数据。

当我添加thyeleaf插件时，它工作正常，当我删除它时，deos无法正常工作 Thymeleaf可处理html目录中的template个文件。然后将这些文件解析到服务器端，并将thymeleaf标签/属性转换为html。

如果您有百里香可用并使用普通的html文件，则这些文件将被发送到客户端，而不会被更改。
