springboot 跨域问题

spring boot 跨域问题 与一个简单的跨域请求测试

SpringBoot解决跨域的5种方式

 

 

package com.sinosoft.framework.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import com.sinosoft.common.constant.Constants;
import com.sinosoft.framework.interceptor.RepeatSubmitInterceptor;

/**
 * 通用配置
 * 
 * @author ruoyi
 */
@Configuration
public class ResourcesConfig implements WebMvcConfigurer
{
    @Autowired
    private RepeatSubmitInterceptor repeatSubmitInterceptor;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry)
    {
        /** 本地文件上传路径 */
        registry.addResourceHandler(Constants.RESOURCE_PREFIX + "/**")
                .addResourceLocations("file:" + RuoYiConfig.getProfile() + "/");

        /** swagger配置 */
        registry.addResourceHandler("/swagger-ui/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/springfox-swagger-ui/");
    }

    /**
     * 自定义拦截规则
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        // 拦截所有的请求
        registry.addInterceptor(repeatSubmitInterceptor).addPathPatterns("/**");
    }

    /**
     * 1.返回新的CrosFilter （全局跨域）
     * 跨域配置
     */
    @Bean
    public CorsFilter corsFilter()
    {
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        // 设置访问源地址
        config.addAllowedOriginPattern("*");
        // 设置访问源请求头
        config.addAllowedHeader("*");
        // 设置访问源请求方法
        config.addAllowedMethod("*");
        // 有效期 1800秒
        config.setMaxAge(1800L);
        // 添加映射路径，拦截一切请求
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", config);
        // 返回新的CorsFilter
        return new CorsFilter(source);
    }

  /*
    2.重写WebMvcConfigure解决跨域问题 （全局跨域）
    实现 WebMvcConfigurer 接口中的 addCorsMappings() 方法来实现跨域
   @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                //是否发送Cookie
                .allowCredentials(true)
                //放行哪些原始域
                .allowedOrigins("*")
                .allowedMethods(new String[]{"GET", "POST", "PUT", "DELETE"})
                .allowedHeaders("*")
                .exposedHeaders("*");

    }*/

    /*
        3.使用注解@CorsOrigin实现跨域 （局部跨域）

        @RestController
        @CrossOrigin(origins = "*")
        public class HelloController {

            @RequestMapping("/hello")
            public String hello() {
                return "hello world";
            }

     */

    /*
     4.自定义filter 解决跨域，（全局跨域）
        https://blog.csdn.net/weixin_39255905/article/details/124341670
     */
    /*
    5.nginx配置中也可以解决跨域
         location / {
           add_header Access-Control-Allow-Origin *;
           add_header Access-Control-Allow-Headers X-Requested-With;
           add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;

           if ($request_method = 'OPTIONS') {
             return 204;
           }
        }

     */
}
