405 Method Not Allowed Spring Boot

HTTP Status 405 with Spring Security with Custom Form Login Using JavaConfig

Resolving the Method Not Allowed (405) Error

Enable HTTP PUT in Tomcat

When encountering the HTTP Status 405 error while using Spring Security with a custom JavaConfig-based login form, it's likely due to Tomcat's default configuration not allowing the HTTP PUT method. To resolve this:

1. Add the following specification to your application's web.xml file to allow the HTTP PUT method:

          <security-constraint>         <web-resource-collection>           <web-resource-name>default</web-resource-name>           <url-pattern>/*</url-pattern>           <http-method>PUT</http-method>         </web-resource-collection>       </security-constraint>     

2. Ensure that your private final log variable is used in your application.
