I have a Spring Framework application and I am migrating it to Spring Boot. How to configure it in such a way that it can create log for each day?
This is my logging configuration so far:
logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate=ERROR
From the docs
Spring boot will use Logback if its in the classpath. If you put a logback.xml in the root of your classpath it will be picked up from there automatically.
You can customize this logback.xml to provide your configurations for adding a rolling appender and so on based on your requirement. The documentation and the examples here will help you.
Update
You can even use log4j2 for logging. Just ensure that the correct dependencies are included. In that case, spring boot will check if there is a log4j2.xml in the classpath. You can provide the required configurations using log4j2.xml.

We have an existing Spring MVC based application. I was asked to plug-in a customization/utility to this project. I am not supposed to do any changes to the existing application.
For the new utility, I thought of doing it through a Spring boot jar. I created a Spring boot jar and placed in the lib folder of the existing application. However, I am facing few issues with this approach and wanted to know if this is the correct approach and if there are any suggestions out there. The issues are:
The logging level of the Spring boot affects the logging level of the existing application. How can I avoid that?
The Spring MVC application and the Spring boot jar both are based on different versions of Spring. What if there are some common class files or packages in both Spring MVC application and the Spring boot jar but with different versions? Will this create any conflicts or will it affect the functionality? I don't want my Spring boot jar to affect the functionality/logging of the existing application. I just want the Spring boot jar to work whenever it is being called explicitly.
For logging issue, I have tried to use something like below in application.properties file but the issue with that is that those settings are considered only if you run the application through #SpringBootApplication main class. But if you just want to package your functionality in a jar file then the application.properties file is not considered.
logging.level.org.springframework = OFF
I am developing a project on DotNet Core , Since DotNet Core no longer supports app.config files, so is there a way where we can start an ignite node by passing ignite configurations in JSON file? If yes can you please share an example?
.NET Core does support app.config files, and Ignite comes with an example that uses app.config on .NET Core.
Check examples/dotnetcore folder of the full distribution, or see on GitHub:
https://github.com/apache/ignite/tree/master/modules/platforms/dotnet/examples/dotnetcore
If you still want JSON (like appsettings.json in ASP.NET Core), you can bind a configuration section to IgniteConfiguration object, see the docs:
https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-2.1&tabs=basicconfiguration#bind-to-an-object-graph
You can use Spring XML in order to configure Ignite instance. Spring config file can be provided via Ignition.Start(string) method and IgniteConfiguration.SpringConfigUrl property. Please take a look at this page: Spring XML configuration
We are in the initial stages of converting a Struts 1.2.9 application to Spring MVC. While the impact has been analyzed and well documented and understood for this migration, we are uncertain if we should introduce Spring Boot in this equation.
I have been reading other threads and would like to state that we are not looking to integrate Struts with Spring - rather we are for sure migrating and moving out of Struts to Spring MVC.
Given this background, invite suggestions/thoughts around below:
Benefit of introducing Spring Boot in this process is more of a distant one of an eventual move to Cloud. As such the team has completed the initial configuration required for a Spring application (like web.xml, required jars, spring-servlet.xml) and not sure of immediate benefits for us.
In case we decide to use Spring Boot in this process, we perceive the impact to be:
i. Add spring-boot-starter-web to our gradle build.
ii. Create a starter Application class
iii. Revisit configurations in web.xml like startup servlets using 'SpringBootServletInitializer'
iv. Continue to use a war based traditional deployment using gradle war plugin. Does this package the spring based libraries into the war or should the libraries be on the server classpath?
I welcome thoughts/suggestions/rejections of this as an approach itself :).
Is it possible to use Spring Data Rest/HATEOAS without Spring Boot, Spring MVC on an persistence storage based application. If so how can this be done?
The short answer is Yes. This has been around even before Spring Boot.
The important thing is to ensure the API jars are on your classpath. Get the latest release of Hateoas here and latest release of Spring Data JPA here and add to the classpath. Just pick from the setup you are using (e.g., Maven, Gradle).
I have been reading how to make web application using spring from the Getting Started Guides, specifically the following guides:
Serving Web Content with Spring MVC
Accessing Data with JPA
But I could not figure how the JPA selected which database driver to store data into.
How can I connect to MySQL database in Spring + JPA.
I learned about Spring + Java Annotations (No XML configurations)
The guides you mention all use Spring Boot.
Spring Boot is a new Spring project that is used for bootstrapping Spring projects. In your case it will auto-configure the datasource for you. Specifically if you have H2 or HSQL on the classpath, Spring will create that in-memory database.
You can easily override the defaults provided by Spring Boot by adding the following properties to application.properties:
spring.datasource.url=jdbc:mysql://whateverhost/whateverdbname
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driverClassName=com.mysql.jdbc.Driver
