spring boot-SpringBoot MDC仅用于下一个日志

关于SpringBoot应用程序和MDC日志的小问题。

我有一个非常简单的SpringBoot web处理程序：

  @GetMapping(path = "/mdcOnlyToThisLogPlease")
    public Mono mdcOnlyToThisLogPlease(@RequestBody Book book) {
        MDC.setContextMap(Map.of("bookName", book.getTitle(), "bookAuthor", book.getAuthor()));
        LOGGER.info("I would like to have a log with bookName and bookValue as first level key for the MDC Json log, and only for this log please");
        return bookService.doSomething(book.getTitle(), book.getAuthor());
    }

在这里，我想在 json 中记录书名和作者作为第一级键，我想得到这个：

{ 
    @timestamp:  2022-02-22T02:22:22.222Z 
    @version:  1 
    bookName: someName
    bookAuthor: someAuthor
    level:  INFO 
    level_value:  20000 
    logger_name:  MyClass 
    message: I would like to have a log with bookName and bookValue as first level key for the MDC Json log, and only for this log please
    spanId:  e58ad767e34525de 
    thread_name:  reactor-http-epoll-1 
    traceId:  ccf32f0b5d210aa2 
}

我认为这段代码可以做到这一点。不幸的是，它还记录了后面的每一个日志的密钥！

例如，我还在 bookService.doSomething() 的日志、健康检查日志等中看到...

{
    @timestamp:  2022-05-02T04:31:30.648Z 
    @version:  1 
    bookName: someName
    bookAuthor: someAuthor
    level:  INFO 
    level_value:  20000 
    logger_name:  reactor.netty.http.server.AccessLog 
    message:  0:0:0:0:0:0:0:1%0 - - [02/May/2022:04:31:30 +0000] "GET /health/readiness HTTP/2.0" 200 5088 19 
    thread_name:  reactor-http-epoll-1 
}

{
    @timestamp:  2022-05-02T04:33:30.648Z 
    @version:  1 
    bookName: someName
    bookAuthor: someAuthor
    level:  INFO 
    level_value:  20000 
    logger_name:  bookService 
    message:  Log from book service. I do not wish to see bookName and bookAuthor as keys
    thread_name:  reactor-http-epoll-1 
}

{ 
    @timestamp:  2022-05-02T04:40:48.742Z 
    @version:  1 
    bookName: someName
    bookAuthor: someAuthor
    level:  INFO 
    level_value:  20000 
    logger_name:  reactor.netty.http.server.AccessLog 
    message:  0:0:0:0:0:0:0:1%0 - - [02/May/2022:04:40:48 +0000] "GET /health/liveness HTTP/2.0" 200 5088 25 
    thread_name:  reactor-http-epoll-1 
}

我可以问一下如何添加密钥，但只能添加下一个/一个日志吗？

非常感谢。
