全局跨域
import org.springframework.context.annotation.Configuration;

@Configuration
public class CorsConfig implements WebMvcConfigurer {

registry.addMapping("/**")
.allowCredentials(true)
.allowedOriginPatterns("*")

控制器跨域
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.HashMap;
@RestController
@CrossOrigin(origins = "*")
public class TestController {
@RequestMapping("/test")
public HashMap<String, Object> test() {
return new HashMap<String, Object>() {{
put("state", 200);
put("data", "success");
put("msg", "");
}};
}
}
