spring boot直接返回静态html

spring boot直接返回静态html

通常spring boot的一般教程的例子都是通过模板来返回页面，比如thymeleaf或者freemarker，但是直接返回html的例子比较少。本文参考文章SpringBoot : How to display static html file in Spring boot MVC application。说明如何让spring boot直接返回html。

一般来说resources/static或者resources/public文件夹可以用来提供js,css,图片等文件访问。不经过配置，直接返回html会报404错误。提供静态html访问主要需要如下配置（懒得翻译了。。。）

• You should create a class that extends WebMvcConfigurerAdapter

• Your class should have @Configuration annotation.

• You class should not have @EnableMvc annotation.

• Override addViewControllers method and add your mapping.

• Override configurePathMatch method and update suffix path matching

其实，添加如下配置类就好了

@Configuration  
public class MvcConfigurer extends WebMvcConfigurerAdapter {  
  
    @Override  
    public void addViewControllers(ViewControllerRegistry registry) {  
        registry.addViewController("/error").setViewName("error.html");  
        registry.setOrder(Ordered.HIGHEST_PRECEDENCE);  
    }
    
    @Override  
    public void configurePathMatch(PathMatchConfigurer configurer) {  
        super.configurePathMatch(configurer);  
        configurer.setUseSuffixPatternMatch(false);  
    }
}
