SOLRJ 7.x expected MIME type application/octet-stream but got text/html.

This occurs because BaseURL fills in the error, and at the very beginning I wrote the address in the browser to access SOLR after booting with Tomcat

The result is a title exception, of course, the hint is 404, there may be a hint 405,method not allowed,method post are not supported and so on

After viewing the source code, we find that the example given is this format Http://ip:port/solr/+core, and re- testing normal after modification .
