春季启动映射操作来查看档案（.html）不工作

Question

我有一个春天启动基本应用

package com.meenakshi.fileupload; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 



@SpringBootApplication 
public class Example { 



    public static void main(String[] args) throws Exception { 
     SpringApplication.run(Example.class, args); 
    } 

} 

我控制器

package com.meenakshi.fileupload.controller; 

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



@Controller 
public class IndexController { 

    @RequestMapping("/") 
    public String index() { 
     System.out.print("REDIRECTED BY MEENAKSHI"); 

     return "index"; 
    } 

} 

我的index.html在src一个基本的HTML文件/主/资源/公用文件夹

我的pom.xml的是

当我做本地主机：8080我希望重定向到index.html，但我越来越白标签错误页面当我添加百里香依赖并添加xmlns：th =“http://www.thymeleaf.org”中.html它的工作原理

如何解决它？另外什么是Spring Boot中的默认视图解析器？我是否强制需要使用百里香？

而且，我需要添加一些application.properties中

Answer 1

有几个方法，你可以暴露你的index.html。

我最喜欢的方式是做如下：

@Configuration 
public class WebMvcConfiguration extends WebMvcConfigurerAdapter { 

    @Override 
    public void addViewControllers(ViewControllerRegistry registry) { 
     registry.addViewController("/").setViewName("index.html"); 
     registry.setOrder(Ordered.HIGHEST_PRECEDENCE); 
    } 

} 

它会自动抓取您的index.html并创建一个默认视图控制器来为它服务。

另一种方式是做像你这样，但返回ModelAndView像下面，但它适应Thymeleaf/JSP更多然后一个SPA：

@Controller 
@RequestMapping("/") 
public class DefaultController { 

    @GetMapping("/") 
    public ModelAndView index() { 
     IndexModel indexModel = new IndexModel(); 
     return new ModelAndView("index", "index", indexModel); 
    } 

}
