I am working on building a SpringBoot app with my workmates. We all have different preferred logging levels for the app. We have been battling back and forth with each other's logging changed to application.properties. Is there a way to move all of the logging.level.* stuff out of that application.properties file and into a ~logging.properties file or something? That way we can add that file to the .gitignore and not track that file so we can each leave our logging alone. We are using Java annotations and not xml btw.
I've tried adding #PropertySource("classpath:logging.properties") to the application file, but I read somewhere that the logging gets setup early on in the init process and this won't work. I tried it anyway and it doesn't work (so confirmed I guess).
I can't believe there's isn't more info on this out there.. I'd imagine the members of a dev team each want their own custom level of logging and don't want to keep stepping on each other's toes/commits.
You can just override it using a command line property. The fallback strategy will take command line -D args as the highest overriding priority.
https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config
I would recommend to have logback.xml file inside resources/ with some defaults that works for everyone (more likely to the application in question) and then you can provide --logging.config=/path/to/your/very/custom/logback.xml file whenever you start the application locally.
That should work for everyone.

I'm working on a SpringBoot (2) application. I'm looking at our properties files which have become a bit convoluted and I'd like to tidy it a little.
In deployment we have a small main/resources/application.properties file which contains a few defaults and an external property file which contains a lot of other properties. This works well... and I'm trying to replicate this in dev and failing and I'm hoping I'm doing something silly which someone can point out painlessly.
As I understand it by default, Spring Boot will look in various places for the properties, in this order...
classpath root
/config in classpath
in the current directory
/config subdirectory of the current directory
Using Intellij I can't get SpringBoot to pick up 2 locations though. If I put all properties in main\resources\application.properties then that's fine. If I use -Dspring.config.name=dev and add a dev.properties with all properties this works well but I can't seem to configure a split in debug between defaults in main\resources\application.properties and a simulation of the external file somewhere else in the project (so that it won't get packaged in the jar).
Is there a simple way to do this, or any good documentation somewhere that I've missed that would explain it well enough that I might be able to simulate it in the dev environment ?
I am using log4j2 in my spring boot application. This works in all respects re: excluding slf4j, including log4j2, etc.
But when the application deploys I need to customize the file for each target host. I have created an ansible role that does this. Ultimately I end up with a log4j2.xml file deployed in another directory e.g. /prod/produsrX/data/log4j2.xml.
I am using the spring-boot-maven-plugin "repackage" goal to generate an executable jar file. It doesn't seem like that should matter but it is a data point in the problem.
This was supposed to be the easiest part of the project. Always before I have just been able to set -Dlog4j.configurationFile - advice which is echoed on about 3,000 web pages and DOES NOT WORK in Spring Boot 2.1.3.
The most useful info I've found is this question. It talks about using -Dlogging.config because logging must be initialized before other properties are read. Unfortunately that didn't help either.
I did find one example that suggested specifying the above directory in a -classpath parameter to java. But that didn't help either.
Does anyone know how to get a spring boot application to read the log4j2.xml file?
The property actually has to be put into the application context (e.g. application.yml). Using a -D property does not work!
logging:
config: /prod/produsrX/data/log4j2.xml #fully qualified name to your log4j.xml
I have a centralized configuration for spring boot service. I followed this link to make it.
I have configServer and configs two separate project. Configs have several properties files. And configServer reading it and rendering to other services.
Now I want to make configs UI based.
e.g.
application.properties of configs which is hosted at git.
logging.path=logs
logging.level.root=INFO
logging.level.org.springframework.boot.autoconfigure.security=INFO
It`s UI should be
logging.path as key text box for value( logs ).
Is there any example for it. Any help will be appreciated.
Thanks.
Since you mention using text box in your post, I'm assuming that by UI you mean GUI.
While I'm not aware of any examples (and you do not specify whether you want to have a destktop or web application) if you're using git to store configuration, your app needs to:
Checkout the git repo with configuration (using JGit for example)
Load properties files generate edit window for each file (something
similar to what IntelliJ does for environment variables in run
configurations perhaps)
Save edits to files
Commit and push changes (again using JGit or a similar library)
I am working on a spring boot application in which i have to set Environment specific properties from user home folder.
i dig Google for the same & found we can put different properties file (dev, test, production) under resources and then we have to tell spring boot which environment we want to use using spring.profiles.active=dev OR prod.
however, my requirement is quite different. i will put a file in user home in my system & want to read properties form that file. how can i do that, need guidance.
Helping hands will be highly appreciated.
From the Spring Boot docs:
You can also refer to an explicit location using the spring.config.location environment property (comma-separated list of directory locations, or file paths).
As the docs go on to state, this must be specified on the command line or as an environment variable.
$ java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
We explain that use case in a Devoxx presentation using EnvironmentPostProcessor, please refer to this section of the presentation for more details. You can also find the code sample online.
Well, it seems in your case you dont need environment variable. For production server your property file will be staying in and in staging machine it is also staying at same place. So where ever you deploy it will pick from . IMO you don't need to set environment, you just have to point property file to
Now to define this path you have 2 ways..
- You can put static path in your code
- You can set environment variable like Property_Path and read it in spring boot application..
However If you want to go one step ahead, you can use spring cloud configuration manager, by passing application+profile name to it, CM can fetch property file from directly from git or file system for you ...
I'm having a stupid configuration issue with Ibatis in my Spring project. Please don't jump on me about how all this was setup, I'm just following the "in house project structure policy".
So here is the structure, we have the "src/main/resources/META-INF/" folder that contains all of our config files used by the application, and then there is a "src/test/resources/META-INF/" that contains only the config files that have different settings to run unit testing.
Well in our case that's only one file, the src/main/resources/META-INF/spring/application-config.xml became the src/test/resources/META-INF/spring/test-application-config.xml. I'm am not going to outline the small differences between the two, because that part works fine.
The test-application-config.xml imports the src/main/resources/META-INF/spring/data-access-config.xml file just fine, which in turns use the src/main/resources/META-INF/ibatis/sqlmap-config.xml successfully... After that is when it goes to Hell.
See up until now we're using Spring to find the next config files in the classpath, but when we hit sqlmap-config.xml we leave the spring framework for the ibatis framework I believe, which loads the resource files defined inside it relative to the classpath (that's taken from the doc, whatever that means).
Inside the sqlmap-config.xml are defined a few resource files we're using that live inside the src/main/resources/META-INF/ibatis/mapping folder.
They are referenced like this:
<sqlMapConfig><sqlMap resource="/META-INF/ibatis/mapping/MyObject.xml"/></sqlMapConfig>
That works fine when I run the app normally, but when I run my JUnit test cases I get an IO exception stating that it can't find the file /META-INF/ibatis/mapping/MyObject.xml.
I've tried to change the path in the sqlmap-config.xml to "mapping/MyObject.xml" but that didn't help. I've also tried to use the Spring classpath prefix "classpath:META-INF/ibatis/mapping/MyObject.xml", didn't work either.
Anyone would have any idea on how to set that Ibatis properly so it works for both the app and the junit?
Thanks.
To solve this problem, I removed all the the Ibatis files and folders from the src/test/resources/META-INF folder.
The sqlmap-config.xml in src/main/resources/META-INF/ibatis/mapping file now maps like this:
<sqlMapConfig><sqlMap resource="META-INF/ibatis/mapping/MyObject.xml"/></sqlMapConfig>
Please note that compared to my initial post the leading "/" is gone... I think that's what made the difference here.
Hopes this helps anyone running into similar issues.
Just to see whether what you are saying is actually the problem.. you might want to place your mappings (MyObject.xml) in the same folder as sqlmap-config.xml. I say this because I've had my fair share of spring + ibatis + unit testing problems. (see resolved question asked by me)
Also, you might be getting IO exception because the mappings file does not exist outside the container (when you run tests).
You should also post definition for bean created from SqlMapClientFactoryBean. This should have configLocation property that contains path to sqlMapConfig xml
I had the same problem and could not find a (quick) solution that explained what exactly could be going wrong. Hence my answer.
As Spring documentation for Ibatis says:
Remember that iBATIS loads resources from the class path, so be sure
to add the 'Account.xml' file to the class path.
In your case by adding META-INF to your webproject build path i.e. if you used Eclipse, set <classpathentry kind="src" path="META-INF"/> in your projects' .classpath (This will be visible under Navigator view in Eclipse)
