我刚从@Configuration
@RestController
public class TestRestController {
static class MyRunnable implements Runnable {
DeferredResult<ResponseEntity<String>> deferredResult;
MyRunnable(DeferredResult<ResponseEntity<String>> dr) {
this.deferredResult = dr;
}
@Override
public void run() {
// do your work here and adjust the following
// line to set your own result for the caller...
this.deferredResult.setResult(ResponseEntity.ok("it worked"));
}
}
@SuppressWarnings("serial")
@ResponseStatus(HttpStatus.TOO_MANY_REQUESTS)
static class TooManyRequests extends RuntimeException {
}
private final ExecutorService executorService = new ThreadPoolExecutor(2, 2,
0L, TimeUnit.MILLISECONDS,
new SynchronousQueue<Runnable>(),
(runnable, executor) -> {
((MyRunnable) runnable).deferredResult.setErrorResult(new TooManyRequests());
});
@GetMapping(value = "/blah", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public DeferredResult<ResponseEntity<String>> yourRestService() {
final DeferredResult<ResponseEntity<String>> deferredResult = new DeferredResult<>();
this.executorService.execute(new MyRunnable(deferredResult));
return deferredResult;
}
}
退出，并且继续遇到CORS问题。我在create-react-app内尝试了以下方法：
webpack-dev-server还有快速中间件：
headers: {
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, PATCH, OPTIONS',
'Access-Control-Allow-Headers': 'X-Requested-With, content-type, Authorization',
'Access-Control-Allow-Credentials': true
},
这些方法都不起作用，因此我选择通过禁用Web安全性来启动浏览器以进行本地开发。问题似乎是所有API调用都确实获得了适当的before(app, server) {
app.use(cors());
// ...
}
，但是，引发错误的资源是我们包含在headers中的内联脚本。有什么想法吗？
浏览器错误：
index.html
