错误
java.lang.IllegalArgumentException: Async support must be enabled on a servlet and for all filters involved in async request processing. This is done in Java code using the Servlet API or by adding "<async-supported>true</async-supported>" to servlet and filter declarations in web.xml. Also you must use a Servlet 3.0+ container
at org.springframework.util.Assert.isTrue(Assert.java:65)
推荐答案
我想您不会显示整个web.xml
.
<async-supported>true</async-supported>
也应该为<filter>
配置.
更新
好吧,你的问题很简单:
Well, your issue is very simple:
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
您确实应该映射所有请求,而不仅仅是 root .
You really should map for all requests, not only the root.
