springMVC报出org.springframework.web.util.NestedServletException: Handler dispatch failed；

场景:

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.setContentLengthLong(J)V
	at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1082)
	at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:963)
	at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:1006)
	at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:909)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:650)
	at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:883)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:731)

主要原因：

1、可能是springmvc的版本过高，需要低于5.3.0；

<dependency&gt;
            <groupId&gt;org.springframework</groupId&gt;
            <artifactId>spring-webmvc</artifactId>
            <version>5.3.13</version>
        </dependency>

或者升级Tomcat的版本。根据测试Tomcat 7.0.78无法使用但是Tomcat 9.0.71可以使用；具体可以看大佬链接:link

代码007普通
