springboot webapi 支持跨域 CORS
1.创建corsConfig 配置文件
@Configuration public class corsConfig { @Autowired varModel varModel_; @Bean public WebMvcConfigurer corsConfigurer() { return new WebMvcConfigurer() { @Override //重写父类提供的跨域请求处理的接口 public void addCorsMappings(CorsRegistry registry) { //添加映射路径 registry.addMapping("/**") .allowedHeaders("*") .allowedMethods("*") .allowedOrigins(varModel_.getCorsStrList()); } }; } }//end
2.varModel中的跨域设置
3.前端页面ajax请求 页面域名,http://localhost:8001
$.ajax({
type: "POST",
url: "http://localhost:8000/a/b",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify({
"requestId": ""
}),
success: function (d) {
console.log(d);
},
error: function () {
//alert("系统错误");
}
});
