java web 几种WEB报表的打印方式

                最近在实现自动调用打印机功能。现在和大家分享一下,要源代码可以联系962589149

                 

之前因为需要,去学习了几种WEB报表的打印方式,发现用Java直接去操作WordExcel还是不那么方便,下面就简单介绍几种;

1、用浏览器自带的打印功能直接打印;

  这种方式是最直接的,方便的,不需要加什么插件jar包,只要前台在一个 div 中模仿着报表的格式去设置界面布局,然后把数据动态的填充进去,再调用JavaScript打印函数,就可以实现界面的局部打印功能。(如果不想让报表div在界面中显示出来可以隐藏之)PS:不过直接在前台界面打印还是会遇到意想不到的情况,不同浏览器的问题,反正我就遇到不同浏览器打印出来的报表排版不一的情况,用的时候需要注意。

  eg

  div布局

 

<div id="printdiv" style="display:none;">

  <table id="tableid" class="main" cellspacing="0" cellpadding="0" border="1"

      bordercolor="#000000" align="center" width="800px;">

       /******    your     code      ******/

   </table>
</div>

 

JavaScript部分:(自己根据需要选择触发响应的JS函数)

 

function windowprint() {

   

    var f = document.getElementById("printdiv");

    f.style.display = "";

    window.print();

    f.style.display = "none";

}

 

function myPrint(obj){

 

    var newWindow=window.open("打印窗口","_blank");

    var docStr = obj.innerHTML;

       newWindow.document.write(docStr);

    newWindow.document.close();

    newWindow.print();

    newWindow.close();

}

 

2、使用第三方插件完成报表打印编辑(这里介绍PageOffice Jacob

  先说PageOffice,这是国产货,其强大之处在于其对Word的处理和它的在线编辑能力,最大的不足就是要收费(不过也不知道怎么收,下载的包里有自带的试用码,也不管先用着玩玩)

  准备:去官网下载java版本的包(http://www.zhuozhengsoft.com/download.html),解压后需要把PageOffice.cabpageoffice.jar两个包放到WEB-INF/lib中去还要在你的web.xml中加入以下部分:

 

<!-- PageOffice Begin -->

  <servlet>

    <servlet-name>poserver</servlet-name>

    <servlet-class>com.zhuozhengsoft.pageoffice.poserver.Server</servlet-class>

  </servlet>

  <servlet-mapping>

    <servlet-name>poserver</servlet-name>

    <url-pattern>/poserver.do</url-pattern>

  </servlet-mapping>

  <servlet-mapping>

    <servlet-name>poserver</servlet-name>

    <url-pattern>/pageoffice.cab</url-pattern>

  </servlet-mapping>

  <servlet-mapping>

    <servlet-name>poserver</servlet-name>

    <url-pattern>/popdf.cab</url-pattern>

  </servlet-mapping>

  <servlet-mapping>

    <servlet-name>poserver</servlet-name>

    <url-pattern>/sealsetup.exe</url-pattern>

  </servlet-mapping>

  <servlet>

    <servlet-name>adminseal</servlet-name>

    <servlet-class>com.zhuozhengsoft.pageoffice.poserver.AdminSeal</servlet-class>

  </servlet>

  <servlet-mapping>

    <servlet-name>adminseal</servlet-name>

    <url-pattern>/adminseal.do</url-pattern>

  </servlet-mapping>

  <servlet-mapping>

    <servlet-name>adminseal</servlet-name>

    <url-pattern>/loginseal.do</url-pattern>

  </servlet-mapping>

  <servlet-mapping>

    <servlet-name>adminseal</servlet-name>

    <url-pattern>/sealimage.do</url-pattern>

  </servlet-mapping>

  <mime-mapping> 

      <extension>mht</extension> 

      <mime-type>message/rfc822</mime-type> 

  </mime-mapping>

  <context-param>

      <param-name>adminseal-password</param-name>

      <param-value>123456</param-value>

  </context-param>

 

  <!--<context-param>

      <param-name>posealdb-driver</param-name>

      <param-value>com.mysql.jdbc.Driver</param-value>

  </context-param>

  <context-param>

      <param-name>posealdb-url</param-name>

      <param-value>jdbc:mysql://localhost:3306/sample</param-value>

  </context-param>

  <context-param>

      <param-name>posealdb-username</param-name>

      <param-value>root</param-value>

  </context-param>

  <context-param>

      <param-name>posealdb-password</param-name>

      <param-value>admin</param-value>

  </context-param>-->

  <!-- PageOffice End -->

 

然后就可以直接用了

  eg:直接贴一个Struts2下使用的Demo好了

 

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;

import org.apache.struts2.interceptor.*;

import com.opensymphony.xwork2.ActionSupport;

import com.zhuozhengsoft.pageoffice.*;

 

publicclass WordDemo extends ActionSupport implements ServletRequestAware, ServletResponseAware{

 

    privatestaticfinallong serialVersionUID = -758686623642845302L;

    private HttpServletRequest request;

    private HttpServletResponse response;

    private String message = "";

   

    publicvoid setServletRequest(HttpServletRequest request) {

        this.request = request;

    }

    publicvoid setServletResponse(HttpServletResponse response) {

        this.response = response;

    }

   

    public String getMessage(){

        return message;

    }

 

    public String openword() throws Exception {

        PageOfficeCtrl poCtrl1 = new PageOfficeCtrl(ServletActionContext.getRequest());

        poCtrl1.setServerPage("poserver.do"); //此行必须

        // 加载控件,可以显示在在线编辑栏中

        poCtrl1.addCustomToolButton("保存", "SaveDocument()", 1);

        poCtrl1.addCustomToolButton("-", "", 0);

        poCtrl1.addCustomToolButton("打印", "ShowPrintDlg()", 6);

        poCtrl1.addCustomToolButton("-", "", 0);

        poCtrl1.addCustomToolButton("全屏切换", "SetFullScreen()", 4);

        poCtrl1.addCustomToolButton("-", "", 0);

        poCtrl1.addCustomToolButton("加盖印章", "AddSeal()", 5);

        poCtrl1.addCustomToolButton("手写签批", "AddHandSign()", 5);

        poCtrl1.addCustomToolButton("验证印章", "VerifySeal()", 5);

       

        poCtrl1.setSaveFilePage("saveword.action");

       

     // 打开WebRoot/doc/test.doc模版
        poCtrl1.webOpen("doc/test.doc", OpenModeType.docNormalEdit, "张三");

        poCtrl1.setTagId("PageOfficeCtrl1"); //此行必须

        return "openword_"+SUCCESS;

    }

   

    public String saveword() throws Exception {

        FileSaver fs = new FileSaver(request, response);

        request.setAttribute("FileSaver", fs);

        String fileName = "\\maker" + fs.getFileExtName();

        fs.saveToFile(request.getSession().getServletContext().getRealPath("doc/")+ fileName);//fs.getFileName()

        fs.showPage(150, 150);

        message = "保存文件至服务器成功!";

        return "saveword_"+SUCCESS;

    }

 

}

 

还可以在模版中设置书签指定动态替换,不过需要注意一点的是在返回的JSP界面中<body>中需要加入

?

<po:PageOfficeCtrl id="PageOfficeCtrl1" />

  关于具体的,可以参考他的文档,是中文的文档,而且官网还可以下载很多Demo参考,没什么可以说的了,PS:不过就是感觉它在网页中直接打开word速度有点慢,不过这可能是微软问题。。

  简单的看了一下,又是要加jar包,还要把它那dll文件放到你的系统路径下,感觉好烦的样子,具体怎么做网上也能找到,不再赘述。

  eg:(贴一个小例子)

 

import com.jacob.activeX.ActiveXComponent;

import com.jacob.com.Dispatch;

import com.jacob.com.Variant;

 

 

publicclass JacobTest {

 

    publicstaticvoid main(String[] args) {

        //启动word,生成一个ActivexComponent对象

        ActiveXComponent app = new ActiveXComponent("Word.Application");

        //要转换的word文件

        String inFile = "D:\\demo.doc";

        //要报存的目标文件

        String tpFile ="D:\\demo1.doc";

        boolean flag = false;

        Dispatch xlo = app.getObject();

        String oldText="1234";

        String newText="test";

        boolean visible=false;

        String bookMarkKey1="LB_KJGG";

        String bookMarkKey2="PO_Sex";

       

        try {

          //设置word不可见

          app.setProperty("Visible", new Variant(visible));

          //log.info("设置word不可见成功!");

          System.out.println("设置word不可见成功!");

          Dispatch docs = app.getProperty("Documents").toDispatch();

          Dispatch doc = Dispatch.invoke(docs, "Open", Dispatch.Method, new Object[]{inFile, new Variant(false), new Variant(true)}, newint[1]).toDispatch(); //打开word文件

          //word2003vba文档中applicationUserName属性。

          String userName=app.getPropertyAsString("UserName");

          System.out.println("用户名:"+userName);

          Dispatch selection=app.getProperty("Selection").toDispatch();

          //得到一个组件

          System.out.println("Selection");

          Dispatch find = app.call(selection, "Find").toDispatch();

 

           //查找什么文本

           Dispatch.put(find, "Text", oldText);

           //替换文本

           Dispatch.call(find,"ClearFormatting");

           Dispatch.put(find, "Text", oldText);

           Dispatch.call(find, "Execute");

           Dispatch.put(selection, "Text", newText);

           // Dispatch.call(app, "SaveAs", inFile);

           System.out.println("replace");

          

           //把指定的值设置到指定的标签中去

           Dispatch activeDocument=app.getProperty("ActiveDocument").toDispatch();

           System.out.println("activedocument");

           Dispatch bookMarks = app.call(activeDocument, "Bookmarks").toDispatch();

           System.out.println("bookmarks");

           boolean bookMarkExist1=Dispatch.call(bookMarks,"Exists",bookMarkKey1).toBoolean();

           boolean bookMarkExist2=Dispatch.call(bookMarks,"Exists",bookMarkKey2).toBoolean();

           if(bookMarkExist1==true){

               System.out.println("exists bookmark!");

               Dispatch rangeItem = Dispatch.call(bookMarks, "Item",bookMarkKey1).toDispatch();

               System.out.println("range item!");

               Dispatch range = Dispatch.call(rangeItem, "Range").toDispatch();

               System.out.println("range !");

               //取标签的值

               String bookMarkValue=Dispatch.get(range,"Text").toString();

              

               bookMarkValue="hello";

                if(bookMarkValue!=null){

                  Dispatch.put(range, "Text", new Variant(bookMarkValue));

                }

           }else{

             System.out.println("not exists bookmark!");

           }

          //保存文件

          Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {tpFile, new Variant(0)}                      , newint[1]);

          //作为word格式保存到目标文件

          Variant f = new Variant(false);

          Dispatch.call(doc, "Close", f);

          flag = true;

        }

        catch (Exception e) {

          e.printStackTrace();

        }

        finally {

          app.invoke("Quit", new Variant[] {});

        }

    }

   

}

 

3、还有一个技术,POI,其实第一个就学的这个。对Excel的处理还行,对word的处理,读取还过的去,但是写入,尤其是写入图片,不知道能么办,而且用起来好麻烦。(真是想不通都搞了10来年的技术了,还这样。。)

eg1:(向word中插入一段文本)

 

import java.io.ByteArrayInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import org.apache.poi.hwpf.model.io.HWPFFileSystem;

import org.apache.poi.poifs.filesystem.DirectoryEntry;

import org.apache.poi.poifs.filesystem.DocumentEntry;

import org.apache.poi.poifs.filesystem.POIFSFileSystem;

 

/*

 * 可以向word中插入文本

 * */

publicclass TestWrite4 {

 

    publicstaticvoid main(String[] args) throws Exception {

       

        HWPFFileSystem files = new HWPFFileSystem();

 

        try

        {

        String str =

        "This is our first doc file Jojiiiiiiiiiiii….We Got IT..But not sure !!";

        str += "rn这是我的第一个doc例子!";

        byte b[] = str.getBytes();

        ByteArrayInputStream bais = new ByteArrayInputStream(b);

 

        POIFSFileSystem fs = new POIFSFileSystem();

        DirectoryEntry directory = fs.getRoot();

 

        DocumentEntry de = directory.createDocument("WordDocument", bais);

 

        FileOutputStream ostream = new FileOutputStream("d:\\testCreate.doc");

 

        fs.writeFilesystem(ostream);

        bais.close();

        ostream.close();

 

        }

        catch (IOException e)

        {

 

        e.printStackTrace();

        }

    }

 

}
