我正在用spring boot开发REST API。我需要记录所有的请求与输入参数(与方法，例如。GET, POST等)，请求路径，查询字符串，此请求对应的类方法，以及此操作的响应，包括成功和错误。例如:
成功的要求:
http://example.com/api/users/1
Log应该是这样的:
{
HttpStatus: 200,
path: "api/users/1",
method: "GET",
clientIp: "0.0.0.0",
accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
method: "UsersController.getUser",
arguments: {
id: 1
},
response: {
user: {
id: 1,
username: "user123",
email: "user123@example.com"
}
},
exceptions: []
}
或请求错误:
http://example.com/api/users/9999
Log应该是这样的:
{
HttpStatus: 404,
errorCode: 101,
path: "api/users/9999",
method: "GET",
clientIp: "0.0.0.0",
accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
method: "UsersController.getUser",
arguments: {
id: 9999
},
returns: {
},
exceptions: [
{
exception: "UserNotFoundException",
message: "User with id 9999 not found",
exceptionId: "adhaskldjaso98d7324kjh989",
stacktrace: ...................
]
}
我希望Request/Response是一个单独的实体，在成功和错误的情况下都具有与该实体相关的自定义信息。
春季实现这一目标的最佳做法是什么，可能是使用过滤器吗?如果是，能否提供具体的例子?
我使用过@ControllerAdvice和@ExceptionHandler，但正如我提到的，我需要在一个地方(和单个日志)处理所有成功和错误请求。
日志请求+自定义格式的有效载荷:
对于自定义格式，只需覆盖Spring日志记录器Bean的超级实现
假设我们希望跳过GET请求，只跟踪INFO日志级别的写请求(PUT, PATCH, DELETE等):
@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter logFilter = new CommonsRequestLoggingFilter() {
@Override
protected boolean shouldLog(HttpServletRequest request) {
return logger.isInfoEnabled() && !Objects.equals(request.getMethod(), "GET");
}
@Override
protected void beforeRequest(HttpServletRequest request, String message) {
// Do nothing if you need logging payload.
// As, Before the Request, the payload is not read from the input-stream, yet.
}
@Override
protected void afterRequest(HttpServletRequest request, String message) {
logger.info(message); // Or log to a file here, as OP asks.
}
@Override
protected @NonNull String createMessage(HttpServletRequest request, @NonNull String prefix, @NonNull String suffix) {
// Output: [PUT][/api/my-entity], user:[my-loging], payload was:[{ "id": 33, "value": 777.00}]
StringBuilder msg = new StringBuilder()
.append(prefix)
.append("[").append(request.getMethod()).append("]")
.append("[").append(request.getRequestURI()).append("]");
String user = request.getRemoteUser();
msg.append(", user:[").append(null == user ? "" : user).append("]");
String payload = getMessagePayload(request);
if (payload != null) {
// It's not null on After event. As, on Before event, the Input stream was not read, yet.
msg.append(", payload was:[").append(payload.replace("\n", "")).append("]"); // Remove /n to be compliant with elastic search readers.
}
msg.append(suffix);
return msg.toString();
}
};
logFilter.setBeforeMessagePrefix("Incoming REST call: -->>>[");
logFilter.setBeforeMessageSuffix("]...");
logFilter.setAfterMessagePrefix("REST call processed: -<<<[");
logFilter.setAfterMessageSuffix("]");
logFilter.setIncludePayload(true);
logFilter.setMaxPayloadLength(64000);
return logFilter;
}
日志请求+响应/状态:
看到https://www.baeldung.com/spring-http-logging custom-request-logging
(如果答案得到需求/达到50+赞，我可以在这里添加准确的代码示例)
如果您不介意尝试Spring AOP，这是我一直在探索的日志目的，它对我来说工作得很好。它不会记录未定义的请求和失败的请求尝试。
添加这三个依赖项
spring-aop, aspectjrt, aspectjweaver
将此添加到xml配置文件<aop:aspectj-autoproxy/>
创建一个可以用作切入点的注释
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD,ElementType.TYPE})
public @interface EnableLogging {
ActionType actionType();
}
现在注释你想要记录的所有API方法
@EnableLogging(actionType = ActionType.SOME_EMPLOYEE_ACTION)
@Override
public Response getEmployees(RequestDto req, final String param) {
...
}
现在来看方面。组件—扫描这个类所在的包。
@Aspect
@Component
public class Aspects {
@AfterReturning(pointcut = "execution(@co.xyz.aspect.EnableLogging * *(..)) && @annotation(enableLogging) && args(reqArg, reqArg1,..)", returning = "result")
public void auditInfo(JoinPoint joinPoint, Object result, EnableLogging enableLogging, Object reqArg, String reqArg1) {
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
.getRequest();
if (result instanceof Response) {
Response responseObj = (Response) result;
String requestUrl = request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
+ "?" + request.getQueryString();
String clientIp = request.getRemoteAddr();
String clientRequest = reqArg.toString();
int httpResponseStatus = responseObj.getStatus();
responseObj.getEntity();
// Can log whatever stuff from here in a single spot.
}
@AfterThrowing(pointcut = "execution(@co.xyz.aspect.EnableLogging * *(..)) && @annotation(enableLogging) && args(reqArg, reqArg1,..)", throwing="exception")
public void auditExceptionInfo(JoinPoint joinPoint, Throwable exception, EnableLogging enableLogging, Object reqArg, String reqArg1) {
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
.getRequest();
String requestUrl = request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
+ "?" + request.getQueryString();
exception.getMessage();
exception.getCause();
exception.printStackTrace();
exception.getLocalizedMessage();
// Can log whatever exceptions, requests, etc from here in a single spot.
}
}
@AfterReturning建议在匹配的方法执行返回时运行
正常。
@ afterthrows通知在匹配的方法执行由退出时运行
抛出异常。
