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）

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;
}
