静态资源存储

找个图片放进去

五个静态资源存储路径：

• classpath:/META-INF/resources/
• classpath:/resources/
• classpath:/static/
• classpath:/public/
• /（webapp）

五个位置，优先级依次降低。

自定义

application.properties 中进行配置

spring.mvc.static-path-pattern=/static/**
spring.web.resources.static-locations=classpath:static/

Java代码配置

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**")
                .addResourceLocations("classpath:static/");
    }
}

忽略favicon.ico请求

package com.zaoshan.server.config;

import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.http.HttpStatus;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@SpringBootConfiguration
public class FaviconConfiguration implements WebMvcConfigurer {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new HandlerInterceptor() {
            @Override
            public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
                if (!"GET".equalsIgnoreCase(request.getMethod()) || !request.getRequestURI().toString().equals("/favicon.ico")) {
                    return true;
                }
                response.setStatus(HttpStatus.NO_CONTENT.value()); // 设置状态码为204 No Content
                return false;
            }
        }).addPathPatterns("/**");
    }
}
