webserv | 42 - Coding a simple HTTP server in C++ | Runtime Evironment library

This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

This is worked around in DDEV v1.18.2+ (and v1.19+), please upgrade. It was a bug in docker-compose 2.2.0+ - please see https://github.com/drud/ddev/issues/3404 for context.

Here is the solution described again, maybe a little bit more convenient:

To fix this problem, I changed in the site-configuration (/etc/nginx/sites-available) of nginx the following variables:

The pathInfo function returns all the path segments for a Request. Perhaps we could define a typeclass that, given a Servant API, produced a "parser" for the list of segments, whose result would be a formatted version of the list.

The parser type could be something like:

I've been looking into this myself for the same reasons and from I can gather you need to use log4j-1.2-api-2.15.0.jar based on the following read:

Perhaps the simplest way to convert to using Log4j 2 is to replace the log4j 1.x jar file with Log4j 2's log4j-1.2-api.jar.

I would like to point out that this shouldn't be the accepted answer but I wanted to give an answer for those who are trying to grasp the situation.

[Edit]

It would seem that log4j-1.2-api-2.15.0.jar is not enough. It helps with migrating Geoserver to the newer log4j version whilst still using the previous main package but it fails to reference to the newer version. As such I also added log4j-api-2.15.0.jar to the mix to complete the pathing.

After this it seems to work again and the version has been updated. I could validate this by using the api of Geoserver (/geoserver/rest/about/manifest.xml) specifically. If you search for log4j before upgrading you'll see 1.2.17 and afterwards 2.15.

Same problem here. Tried different settings but with no solution.

Workaround: Downgrade RabbitMQ to 3.8. After downgrading there were no connection errors anymore. So, I think it must have something to do with different behavior of v3.9.

Express should be able to resolve the path-placeHolder (through :), even if it's within this rather unusual parentheses. So try defining your endpoint as follows:

You need to at least expose the 3030 port on the app container to make it available to other containers:

Browser allows any http request to the origin ( url where your http session started ). In single page applications we usually load the DOM which intern makes additional XHRs to a new domain (usually a new web app/rest api) . This is considered as a security flaw and all of the reputable and modern browsers stopped supporting this behavior.

To mitigate this you need a proxy in origin domain. All of the request to get data should pass through it.

In angular you can :

1. Configure the server to send the appropriate CORS headers
2. Configure Angular CLI proxy

I suggest using angular CLI proxy rather than adding CORS configuration.
