@Async使用记录

Before：

1号

@ApiOperation("保存日志")
@PostMapping("/saveLog")
@Override
public ApiResult saveLog(@RequestBody Req req) {
    return logManager.saveLog(req);
} 

 2号

@Async
@Override
public ApiResult saveLog(Req req) {
    logService.saveBusinessLog();
    return ApiResult.success(Boolean.TRUE);
}

 3号

@RestControllerAdvice
@Order(-2147483628)
@ConditionalOnProperty(prefix = "response.wrap",name = "enabled",matchIfMissing = true)
@Slf4j
public class ResponseWrapHandler implements ResponseBodyAdvice {
    @Override
    public boolean supports(MethodParameter returnType, Class converterType) {
        return true;
    }

    @Override
    public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {
        if (body instanceof ApiResult
                ||returnType.hasMethodAnnotation(SkipWrap.class)
                ||body instanceof String
                ||HttpContext.isFeignRequest()
                || PathMatchUtil.match(MainClassConstant.SWAGGER_URL, HttpContext.getRequest().getServletPath())
                ){
            return body;
        }
        return ApiResult.success(body);
    }
}

Before结果：

此时，1号返回的是：

{

    "success": true,

    "code": "200",

    "msg": "请求成功",

    "traceId": "",

    "data": null

}

 

 After:

@ApiOperation("保存日志")

@PostMapping("/saveLog")

@Override

public ApiResult saveLog(@RequestBody Req req) {

     logManager.saveLog(req);

     return ApiResult.success(Boolean.TRUE);

} 

After结果：

{

    "success": true,

    "code": "200",

    "msg": "请求成功",

    "traceId": "",

    "data": true

}

 

代码执行顺序：

1号 -》3号 -》2号

2号中抛出异常也不会对1号有任务影响
