Application.properties UTF-8

When building a Java Spring application, the application.properties file is an important configuration file that is used to set various properties for the application. One common requirement is to set the file encoding to UTF-8, especially if the application needs to handle non-English characters.

To set the file encoding to UTF-8, add the following line to the application.properties file:

spring.mvc.encoding.charset=UTF-8

This sets the default character encoding to UTF-8 for all HTTP requests and responses. It is also possible to set the character encoding for specific content types, such as JSON and XML, by using the following properties:

spring.http.encoding.charset=UTF-8
spring.http.encoding.force=true
spring.jackson.default-property-inclusion=non_null

This ensures that JSON and XML responses are also encoded in UTF-8.

Another important property is file.encoding, which sets the default character encoding for reading and writing files. To set the file.encoding to UTF-8, add the following line to the application.properties file:

file.encoding=UTF-8

This ensures that all files are read and written with UTF-8 encoding.

In addition to these properties, there are many other properties that can be set in the application.properties file, such as database connection settings, logging configuration, and server port. It is important to set these properties correctly to ensure that the application functions properly.

Overall, setting the application.properties file to UTF-8 encoding is an important step in developing a Java Spring application that needs to handle non-English characters. By following the best practices in application configuration, developers can ensure that their applications are secure, reliable, and scalable.
