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Word、Excel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 和 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.cab和pageoffice.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.*;

public class WordDemo extends ActionSupport implements ServletRequestAware, ServletResponseAware{ 

    private static final long serialVersionUID = -758686623642845302L;
    private HttpServletRequest request;
    private HttpServletResponse response; 
    private String message = "";
    
    public void setServletRequest(HttpServletRequest request) { 
        this.request = request; 
    }
    public void 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。。

  B:jacob

  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;


public class JacobTest {

    public static void 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)}, new int[1]).toDispatch(); //打开word文件
          //在word2003的vba文档中application有UserName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)}                      , new int[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
 * */
public class TestWrite4 {

    public static void 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();
        }
    }

}

还有一些具体的功能操作,以及对于Excel的操作,推荐一个网站介绍的比较好。http://word.apachepoi.com/

还在网上看到可以通过 Applet方式完成报表的打印,不过没去研究过。。
