Testing Spring Boot API results in HTTP 405 (Method not Allowed) on PUT

Question

I created an API which I deployed to Tomcat Server. During development, I would start the application from Eclipse and test the end point using Postman. From Eclipse, the application runs fine. I would see my bot (created with Selenium WebDriver) starting, hitting the targeted pages, clicking the scripted elements, and finishing the process.

I modified the POM to build a WAR file which I manually deployed using Tomcat Manager App page. The WAR deployed and it is running fine as far as I can tell. I decided to run the same test using Postman; obviously changing "localhost" to the actual IP address and port. Unfortunately, I get this HTTP 405 error and I do not know why. I assume that something needs to be configured in Tomcat but I have no clue as to what specifically I need to do.

I configured Tomcat according to this and still no luck: http://www.codereye.com/2010/12/configure-tomcat-to-accept-http-put.html

Answer 1

Tomcat by default is not enabled for HTTP PUT command.

I had to configure Tomcat by modifying the web.xml and the tomcat-users.xml files.

Changes to web.xml file

1. Needed to add readonly=false parameter

<init-param> <param-name>readonly</param-name> <param-value>false</param-value> </init-param> 

2. Needed to add a security constraint for the role

<security-constraint> <web-resource-collection> <web-resource-name>Demo App</web-resource-name> <url-pattern>/*</url-pattern> <http-method>PUT</http-method> </web-resource-collection> <auth-constraint> <role-name>#####</role-name> </auth-constraint> </security-constraint> 

Changes to the tomcat-users.xml file

1. Needed to add a user and role to match the added security constraint

<user name="#####" password="#####" roles="#####" />
