Setting 'relaxedQueryChars' for embedded Tomcat

Alex Karasev :

How can I set relaxedQueryChars for Spring Boot embedded Tomcat?

The connector attribute described here, but Spring Boot documentation has no such parameter listed.

How to set Tomcat's Connector attributes in general?

I am not sure if you can do this with properties file. I believe this should work

@Component
public class MyTomcatWebServerCustomizer
        implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {

    @Override
    public void customize(TomcatServletWebServerFactory factory) {
        factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
            @Override
            public void customize(Connector connector) {
                connector.setAttribute("relaxedQueryChars", "yourvaluehere");
            }
        });
    }
}
