url 不对哦。

[Ant_Shen]

web.xml中 <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> 这里指定拦截的url以.do结尾 修改一下url，或者url-pattern

[qkjoe]

同楼上，默认设置的过滤方式是以.do结尾，所以url最后也应该加个.do

[qq_28054181]

@qkjoe @Ant_Shen @rui888 @somnus623 加了.do还是没反应~~~~~~~~

[Ant_Shen]

应该是xxx/logins.do，不要写错了，能否把错误贴出来，详细

[qq_28054181]

function submits() { var url="${pageContext.request.contextPath}/logins.do"; $.post(url,{username:$("#userNames").val(),password:$("#password").val()},function(data){ alert("进入"); if(data.message == 'success'){ alertMsg('登录成功！','success'); window.location.href='${pageContext.request.contextPath}/main.jsp'; }else{ alert("账号或密码有误"); } }); }

[qq_28054181]

@Ant_Shen 没有错误提示

[qq_28054181]

这是在谷歌浏览器上点击登录后的结果

[Ant_Shen]

这样配置应该是没错的，你试下在web.xml中的url-parttern改成 /

[qq_28054181]

ajax里url总是显示找不到

URL写错了吧，后缀不是.do吗

[忧伤等待]

你貌似没写前缀吧！

[执笔记忆的空白]

为何你的controller上面是 / ？ 这样能行？
