普通设置
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Headers", "*");
response.setHeader("Access-Control-Allow-Methods", "*");SpringBoot 中实现 WebMvcConfigurer 接口，并重写 addCorsMappings 方法
@Override
public void addCorsMappings(CorsRegistry registry) {
registry
.addMapping("/**")
.allowedOrigins("*")
.allowedHeaders("*")
.allowedMethods("*")
.allowCredentials(false)
.maxAge(3600);
}
