错误： <no source info> ：公共类org.apache.commons.dbcp.BasicDataSource

Question

This error (with all related 'unresolved type' errors) appeared while installing Maven project. There were no changes related to dbcp, I tried to delete all the local repos, installed again and commons-dbcp was downloaded, so dependencies are fine I suppose (actually I could install with the same dependencies a couple of hours ago). What could be a reason of such behaviour?

Answer 1

好吧，在这种情况下，我遇到了一个问题，因为其中一个演示者未使用服务器端类的导入（我曾把它错误地放在那儿，然后忘记了），这可能是尝试自动布线的原因。 bean处于应用程序上下文中，而现在不是合适的时机。
