This depends a great deal on which country you are talking about. I will look briefly at the reactions of people in the United States and in Germany.
In the US, the treaty never did get ratified by the Senate. This was because the people were not sufficiently in favor of the treaty to force the Senate to pass it. Many Senators did not like the idea of the League of Nations and so they opposed the bill. Pres. Wilson tried to persuade the people to pressure the Senate to pass the bill, but the Senate did not.
In Germany, the whole treaty was hated. The treaty assigned all blame for the war to Germany. It forced Germany to pay reparations to the winners. Both of these clauses (as well as others that also weakened Germany) made the German people very angry. It was their anger that eventually allowed Hitler to come to power promising to break the Treaty of Versailles.
