HelloController.java
@Controller
public class HelloController {
@RequestMapping(path="/hello")
public String helloHandler() {
System.out.println("方法執行");
return "ok";
}
}
tomcat版本是9.0.x的 spring依賴的版本都是5.1.8 在跳轉頁面時, 控制器的方法的確是執行了的. 后臺列印了"方法執行"
各位大佬幫忙看看是哪里出了問題!!! 謝謝!!!!
uj5u.com熱心網友回復：
NoSuchMethodError 是版本兼容問題。Spring組件涉及多個包，要配套。
uj5u.com熱心網友回復：
java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotationUtils.clearCache()V估計是包的版本沖突，檢查一下是不是有重復的jar，或者版本不一致。
