该追踪中最重要的部分似乎是

 The servlets named [com.example.teamonelibraryapp_.Teamonelibraryapp_UI$Servlet] and 
 [ui.AppMain$Servlet] are both mapped to the url-pattern [/*] which is not permitted
    at org.apache.catalina.deploy.WebXml.addServletMapping(WebXml.java:293)

所以最有可能的是，将这些servlet映射到不同的url将解决您的问题。

java.lang.IllegalArgumentException：名为[X]和[Y]的servlet都映射到url-pattern [/ *]，这是不允许的
