Project Organization using Eclipse modules

-
Project organization is a critical aspect of software development. A well-organized project can save developers time and effort in the long run, making it easier to maintain, modify, and scale a project. Eclipse is a popular Integrated Development Environment (IDE) that offers a variety of features and tools for software development. One of the most powerful features of Eclipse is the modular architecture, which allows developers to separate code into manageable modules.  In this article, we will discuss best practices for organizing Eclipse projects using modules.

Modules are a collection of related files that are organized together in a separate package or directory. Modules can help keep the project well-organized and promote code reuse. Modules also help to maintain SOLID principles by compartmentalizing project responsibilities. 

Here are some best practices for organizing Eclipse projects using modules:
  1. Separate modules for separate functionalities: It's best to create separate modules for each functionality or feature of the project. For example, if your project has a login feature, create a separate module for it. This approach helps maintain the codebase and makes it easier to modify or add new features.

  2. Use meaningful names for modules: Naming modules correctly is essential to identify the functionality they represent. A well-named module should be descriptive, easy to understand, and meaningful. A good practice is to use names that describe the module's purpose or the feature it implements.

  3. Follow a consistent package naming convention: A consistent package naming convention helps keep the project organized and easy to navigate. It's recommended to use a reverse domain name convention for packages, for example, com.example.project.module1.

  4. Maintain a clear module hierarchy: A clear module hierarchy helps developers understand the dependencies and relationships between different modules. For example, if a module has dependencies on other modules, it should be placed at a higher level in the hierarchy.

  5. Use modularization to promote code reuse: Modules are a great way to promote code reuse. Instead of duplicating code, modules can be designed to provide a set of functionalities that can be used in different parts of the project. This approach helps to reduce development time and effort.

  6. Use module dependencies to manage project complexity: Module dependencies help manage the complexity of the project. By defining module dependencies, you can ensure that the modules are loaded in the correct order and have the necessary dependencies available.

  7. Use version control: Version control is essential in any development project. It helps to track changes and revert to previous versions if necessary. Using version control also makes it easier to collaborate with other team members.

  8. Keep the module interfaces clean: The module interface should be kept clean and simple. The interface should provide only the necessary methods and data.

  9. Use a parent project to organize all modules and library dependencies within across the application. This ensures all modules use the same library versions.

  10. Test each module. It is essential to test each module thoroughly to ensure that it performs the intended function correctly. Testing should be done before integrating the module with the rest of the project. Eclipse provides tools to create and run tests for each module.

  11. Document the modules. It is important to document each module's purpose, functionality, and dependencies. Documentation makes it easier for new team members to understand the project's structure and helps to maintain the project in the future.
In conclusion, using Eclipse modules can improve project organization and development efficiency. By following these best practices, developers can create well-organized, maintainable, and scalable projects. With Eclipse's modular architecture, developers can break down complex projects into smaller, more manageable components, making it easier to develop and maintain large-scale software applications.

Max Upload File Size in Spring Framework

-
  Spring framework comes preconfigured with default upload file size and max request size. You can modify the sizes with application settings. Settings max-file-size  specifies the maximum size permitted for uploaded files. The default is 1MB max-request-size  specifies the maximum size allowed for multipart/form-data requests. The default is 10MB. Error exceeding max file size Java with Spring 6 will throw a  MaxUploadSizeExceededException  exception when the max size is exceeded. threw exception [ Request processing failed: org . springframework . web . multipart . MaxUploadSizeExceededException : Maximum upload size exceeded ] with root cause org . apache . tomcat . util . http . fileupload . impl .

Use Java Enums with JPA

-
Java Persistence API (JPA) is a widely used standard for object-relational mapping (ORM) in Java applications. One of the common challenges when working with JPA is mapping database columns to Java enums. This can be especially challenging if the database column is not a string, such as when using an integer or a byte as the database column type. In this article, we will explore how to use Java enums with JPA. Mapping Java enums to database columns Before we dive into the details of how to use Java enums with JPA, let's first discuss how JPA maps Java enums to database columns. JPA provides two basic ways to map Java enums to database columns: Ordinal-based mapping : This maps the enum's ordinal value (the position of each enum value in the enum declaration) to the database column. For example, if we have an enum named Status with values ACTIVE, INACTIVE, and SUSPENDED, ACTIVE will have an ordinal value of 0, INACTIVE will have an ordinal value of 1, and so on. Name-based mappi...

Spring Security part 3 - OidcUser

  In the last article, I showed you how to return your own   UserDetails   object via a bean interface for username/password authentication. But what if you want to use OAuth authentication too? Spring Security works differently with OAuth but with a little engineering we can bring it all together into a cohesive solution.
