ssm框架动态sql拼接异常

Question

tomcat启动报
[ERROR] localhost-startStop-1 10:46:42 Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping#0': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping found. Cannot map 'smsGatewayStatisticsController' bean method
请问正确的sql该怎么拼接?
