springmvc 解决跨域问题的最佳方案

You can add to your @RequestMapping annotated handler method a @CrossOrigin annotation in order to enable CORS on it (by default @CrossOrigin allows all origins and the HTTP methods specified in the @RequestMapping annotation):

@RestController
@RequestMapping("/account")
public class AccountController {

    @CrossOrigin
    @GetMapping("/{id}")
    public Account retrieve(@PathVariable Long id) {
        // ...
    }

    @DeleteMapping("/{id}")
    public void remove(@PathVariable Long id) {
        // ...
    }
}
