java sprinvmvc 文件上传

1、配置文件 /wbh-adapter-h5/src/main/resources/dispatcher-servlet.xml

<!-- 文件上传需要配置该句 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

2、jquery.form 提交表单；

$(function(){
    //异步提交表单
    $("#ajaxSubmit").on("click",function(){
        console.log($(this));
        $("#uploadForm").ajaxSubmit({
            type:‘post‘,
            url:‘${context}/mobile/uploadimgs‘,
            success:function(data){
                console.log(data);
                var data= eval(data);
    			if(data.errorCode=="1"){
    				 $.alert(data.errorMessage);
    			}else{
    				$.showPreloader(‘编辑成功...‘);
    			      setTimeout(function () {
    			        $.hidePreloader();
    			        window.location.href=‘${context}/weish/index‘;
    			      }, 2000);

    			}
            },
            error:function(XmlHttpRequest,textStatus,errorThrown){
                console.log(XmlHttpRequest);
                console.log(textStatus);
                console.log(errorThrown);
                $.showPreloader(‘服务器异常,请重试...‘);
            }
        });
    });
});
