日志里报错的地方不少，但其实关键的就标黄那里。我们知道日志堆栈需要反着看，标黄处是异常抛出来的地方，下面才是开始依次执行逻辑的步骤，这里大概说下：启动tomcat时会解析注解WebServlet，去添加Servlet的映射，但这时它发现已经存在该Servlet的配置了，抛出了异常。webXml类的添加Servlet映射方法的代码如下：
public void addServletMappingDecoded(String urlPattern, String servletName) {
String oldServletName = servletMappings.put(urlPattern, servletName);
if (oldServletName != null) {
// Duplicate mapping. As per clarification from the Servlet EG,
// deployment should fail.
throw new IllegalArgumentException(sm.getString(
"webXml.duplicateServletMapping", oldServletName,
servletName, urlPattern));
}
servletMappingNames.add(servletName);
}
因为从web.xml中已经put进servletMapping了，所以从@WebServlet中再put进去发现了相同servlet配置，抛出重复servlet映射错误。@WebServlet或者web.xml中去掉一个就可以了。
