1、注意添加
2、如果集成了shiro一定要注意在mapping中增加dispatcher项,否则会抛出org.apache.shiro.UnavailableSecurityManagerException异常
3、如果项目用到了ehcache gzip filter,在异步请求返回时会抛出java.io.IOException: write beyond end of stream异常,解决方案是将gzip filer 换成com.googlecode.webutilities的compressionFilter
<async-supported>true</async-supported>在web.xml中对DispatcherServlet和所有filter添加<async-supported>true</async-supported>
2、如果集成了shiro一定要注意在mapping中增加dispatcher项,否则会抛出org.apache.shiro.UnavailableSecurityManagerException异常
<filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>ASYNC</dispatcher> </filter-mapping>
