注意&＃xff1a;如果提交报错&＃xff0c;数据根本就没有传递到后台&＃xff0c;那么可以试着把提交路径改为

&＃39;uploader&＃39;       : &＃39;upload.action;jsessionid&＃61;${pageContext.session.id}&＃39;,//请求路径

如果web.xml中的配置为&＃xff1a;

struts2

/*

那么路径可以为&＃xff1a;

&＃39;uploader&＃39;       : &＃39;upload;jsessionid&＃61;${pageContext.session.id}&＃39;,//请求路径

如果web.xml配置为&＃xff1a;

struts2

*.action

那么提交路径必须为&＃xff1a;

&＃39;uploader&＃39;       : &＃39;upload.action;jsessionid&＃61;${pageContext.session.id}&＃39;,//请求路径

如果需要在UploadAction中使用session&＃xff0c;那么在路径后把jsessionid&＃61;${pageContext.session.id}&＃39;加上&＃xff0c;如果不需要使用session可以不用加。
