Tomcat maven插件 - 无法加载类"org.slf4j.impl.StaticLoggerBinder"

当我在一个独立的tomcat容器中启动我的webapp时,我看到Flyway日志记录正常(如果找到则使用commons-logging,如下面的Axel所述,则使用sout).

但是,当我使用apache tomcat maven插件(tomcat7-maven-plugin)时,我看到以下内容:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

没什么好看的.这是完整的代码:

public void contextInitialized(ServletContextEvent sce) {
    Flyway flyway = new Flyway();
    flyway.setDataSource(...);
    flyway.migrate();
}

<listener>

我正在使用logback-classic进行日志记录.泽西和吉斯都记录正常(虽然我删除它们以缩小问题范围).

这是我在类路径中看到的唯一与日志相关的jar:

所以我更新的问题是,为什么使用tomcat maven插件vs独立存在差异？我没有在"target"文件夹中看到临时部署的任何其他jar.

更新:添加jcl-over-slf4j后,问题就消失了.

无法在 tomcat 8 中设置 sso/ssl

我正在尝试在 tomcat 8 中设置 ssl，并且遵循了我公司为 tomcat 7 编写的文档。该文档适用于 tomcat 7，但是当我在 tomcat 8 中尝试相同的操作时，我在 catalina 中收到以下错误。输出日志文件。您能告诉我导致此错误的原因吗？顺便说一句，日志文件中的 sso 指的是我创建的一个简单的 hello world war 应用程序来测试 sso/ssl。

Nginx反向代理性能低下

尝试配置 Nginx 有两个目的：

反向代理将请求重定向到本地 tomcat 服务器（mcat 监听的端口 443 到 10443）
将请求镜像到后端服务器以进行分析

由于我们使用默认配置和镜像指令时遇到了非常低的性能，因此我们决定尝试使用反向代理来检查是否对服务器有影响，并且确实看起来 nginx 将流量限制了几乎一半（我们正在使用 Locust和 Jmeter 作为加载工具）

Nginx 版本：1.19.4

尝试了10 个提高 10 倍应用程序性能的技巧并调整 NGINX 性能，但没有效果。运行 nginx 和 tomcat 的机器应该足够强大（EC2 c5.4XLarge），我们没有看到资源缺乏，但网络上限更多。TIME_WAIT 连接数非常高 (20k-40k)

从机器角度：

增加网络端口范围（1024 65300）
降低 tcp_fin_timeout (15ms)
将最大 FD 增加到最大

Nginx视角（之后添加nginx.conf）：

keepalive_requests 100000；keepalive_timeout 1000；
worker_processes 10（16 是 CPU 数量）
工人连接数 3000；
worker_rlimit_nofile 100000；

nginx.conf：

user  nginx;
worker_processes 10;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


worker_rlimit_nofile 100000;
events {
   worker_connections  3000;
}


http {
   include       /etc/nginx/mime.types;
