my java learning

1，首先是html页面（imgTest.jsp）

    <span class="htgl_addpro_content_high_content" style="margin-left: 10px;">
       <p>
           <img id="imgsrc" src="<%=basePath%>images/nopic.gif" width="131" height="180"></p>
       <p>
           <input type="text" id="imageUrlTmp" name="htglBookInfo.imageName" disabled value="" style="width: 220px; height: 28px; float: left;" class="txt1 isChanged"><input type="hidden" id="imageUrl" name="htglBookInfo.imageName" value="" style="width: 400px; height: 28px; float: left;" class="txt1 isChanged"><input id="chooseImg" type="button" class="darkBtn" value="浏览" style="height: 34px; width: 100px; margin-left: 45px; float: left;" size="10"><input type="file" id="fileField1" style="" name="file"><input type="text" style="" value="<%=basePath%>" id="imgPath"><input type="text" style="" id="imgUrlToDb" name="htglBookInfo.imageUrl" value="${htglBookInfo.imageUrl }"></p>
   </span>

2，struts配置（struts.xml)

<?xml version="1.0" encoding="UTF-8" ?><struts><constant name="struts.devMode" value="true"></constant><constant name="struts.xwork.chaining.copyErrors" value="true"></constant><constant name="struts.xwork.chaining.copyFieldErrors" value="true"></constant><constant name="struts.xwork.chaining.copyMessages" value="true"></constant><constant name="struts.multipart.maxSize" value="10485760"></constant><include file="struts-default.xml"></include><package name="wxcm" extends="json-default"><action name="imgUpLoad" class="imageUpload" method="imgUpLoad"><interceptor-ref name="fileUploadStack"></interceptor-ref><result type="json" name="success"><param name="root">htglImgUrl
                <param name="contentType">text/html
                <param name="bufferSize">40960
                
            </result><result type="json" name="error"><param name="contentType">
                    text/html

            </result></action><action name="showImg" class="imageUpload" method="showImg"><result name="imgReadSuccess" type="stream"><param name="contentType">image/jpeg,image/gif,image/bmp
                <param name="inputName">imageStream
                <param name="bufferSize">4096
            </result></action></package></struts>

4，spring配置文件（application.xml）

5，web.xml配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext.xml</param-value></context-param><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>*.action</url-pattern></filter-mapping><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><welcome-file-list><welcome-file>imgTest.jsp</welcome-file></welcome-file-list><session-config><session-timeout>30</session-timeout></session-config></web-app>

6，需要相关的js插件
jquery-1.11.1.min.js 和 ajaxfileupload.js

7，自己写的相关图片上传js代码（imgUpload.js）

function changeUrl(){
    var path = $('#fileField1').val();
    //alert("path==="+path);
    var post = path.lastIndexOf("\\");
    //alert("post==="+post);
    $('#imageUrl').val(path.substring(post + 1, path.length));
    $('#imageUrlTmp').val(path.substring(post + 1, path.length));
    alert(path.substring(post + 1, path.length));
    var imgup = document.getElementById("imageUrl");
    if (imgup.value == "") {
        return;
    }
    // 判断是否是图片格式
    var imgname = imgup.value.substring(imgup.value.lastIndexOf("."), imgup.value.length);
    imgname = imgname.toLowerCase();
    /*if (!equalsIgnoreCase(imgname,'.jpg') && !equalsIgnoreCase(imgname, '.gif')) {
        alert("请选择图片文件，谢谢!");
        imgup.focus();
        // 清空file里面的值
        $("#imageUrl").attr("value", "");
        $("#imageUrlTmp").attr("value", "");
    } else {
        // 显示图片
        $.ajaxFileUpload({
            url : 'imgUpLoad.action?'+new Date().getTime(),
            secureuri : false,

                $("#imgsrc").attr("src", "showImg.action?"+new Date().getTime()+"&imgPath="+result[0].htglImgUrl);
            }
        });
    }*/
// 显示图片
    $.ajaxFileUpload({

        success : function(result) {
            $("#imgsrc").attr("src", "showImg.action?"+new Date().getTime()+"&imgPath="+result[0].htglImgUrl);
        }
    });
}

//忽略大小写比较字符串是否相等
function equalsIgnoreCase(str1, str2){
    if(str1.toUpperCase() == str2.toUpperCase()){
        return true;
    }
    return false;
}

8，pox.xml文件配置
