AntPathMatcher replace with PathPatternParser

AntPathMatcher setCaseSensitive not working?

Did you update the version of Spring Boot? Did your URI case insensitivity stop working?

Did you have something like this:

@Configuration

public class WebConfig implements WebMvcConfigurer

{

    @Override

    public void configurePathMatch(PathMatchConfigurer configurer)

    {

        AntPathMatcher matcher = new AntPathMatcher();

        matcher.setCaseSensitive(false);

        configurer.setPathMatcher(matcher);

    }

Change it to something like this:

@Configuration

public class WebConfig implements WebMvcConfigurer

{

    @Override

    public void configurePathMatch(PathMatchConfigurer configurer)

    {

        PathPatternParser patternParser = new PathPatternParser();

        patternParser.setCaseSensitive(false);

        configurer.setPatternParser(patternParser);

    }

If you want to continue to use AntPathMatcher, add this to your application.properties file:

spring.mvc.pathmatch.matching-strategy=ant-path-matcher

Boxing an Array in Swift

Swift Arrays

If you are reading this you probably have the need to work with an array returned from a function or a copy of an array. I have been porting a complex data transfer object (DTO) from Java to Swift. The Java implementation of this DTO has many violations the Law of Demeter.

The Swift implementation needs to resemble the Java implementation so that changes to one code base will be easier to make in the other code base. This requirement lead me to creating a Boxed Array which I named "List".  Before critiquing the name of the class or the method names, this is to make the port from Java as simple as possible FOR ME. You can make List implement the methods of a Swift Array if you want, or make Protocols for your own "collection classes".

This example of Boxing / Wrapping a Swift Array is as simple as possible. This includes the ability to serialize the List class to be the same as an Array when serialized to JSON.
