定义跨域ip 域名

cors.addMapping=/**
cors.allowedOrigins=http://localhost,http://localhost:8080,https://www.baidu.com
cors.allowCredentials=true
cors.allowedMethods=GET,POST,PUT,DELETE,OPTIONS
cors.max_age=3600

• 读取配置文件

• @ConfigurationProperties(
      prefix = "cors"
  )
  public class CorsProperties {
      private String addMapping;
      private String[] allowedOrigins;
      private Boolean allowCredentials;
      private String[] allowedMethods;
      private Integer maxAge;
  }
  

• 配置跨域

• @Configuration
  @EnableConfigurationProperties({CorsProperties.class})
  public class CorsConfig implements WebMvcConfigurer {
      @Autowired
      private CorsProperties properties;
  
      public CorsConfig() {
      }
  
      public void addCorsMappings(CorsRegistry registry) {
          registry.addMapping(this.properties.getAddMapping())
                  .allowedOrigins(this.properties.getAllowedOrigins())
                  .allowCredentials(this.properties.getAllowCredentials())
                  .allowedMethods(this.properties.getAllowedMethods())
                  .maxAge((long) this.properties.getMaxAge());
          
      }
  }
