一、介绍 Jacob 是Java-COM Bridge的缩写,它在Java与微软的COM组件之间构建一座桥梁。使用Jacob自带的DLL动态链接库,并通过JNI的方式实现了在Java平台上对COM程序的调用。 二、安装和配置 Jacob是一个开源软件,它的官方站点是:http:///jacob/ 大家可以到上面下载源代码研究,也可以直接下载编译后的二进制文件。 下载包jacob_x.x.zip,解压后有几个文件:jacob.jar、jacob.dll等 把jacob.dll拷贝到%JAVA_HOME%\jre\bin目录下,%JAVA_HOME%就是JDK的安装目录或是C:\Windows\System32下面 接着直接在java IDE中引用jacob.jar就可以使用了 三、jacob.jar的结构 jacob包括两个部分: com.jacob.activeX: ActiveXComponent类 com.jacob.com: 其它类和元素 四、Jacob类 Jacob的结构很简单,包含以下几个类: ActiveXComponent Class:封装了Dispatch对象,用于创建一个封装了COM组件对象的Java Object Dispatch Class:用于指向封装后的MS数据结构。常用的方法有call,subcall,get,invoke…后面会介绍使用方法。 Variant Class:用于映射COM的Variant数据类型。提供Java和COM的数据交换。 ComException Class:异常类 五、Jacob方法 用于访问COM/DLL对象的方法,读取、修改COM/DLL对象的属性。 call method:属于Dispatch类。用于访问COM/DLL对象的方法。方法进行了重载,方便不同场合调用。返回一个Variant类型的值。 callSub method:使用方法和call一样,不过它不返回值。 get method:读取COM对象的属性值,返回一个Variant类型值。 put method:设置COM对象的属性值。 invoke method:call的另一种用法,更复杂一些。 invokesub method:subcall的另一种用法 getProperty method:属于ActiveXComponent类,读取属性值,返回一个Variant类型值。 setProperty method:属于ActiveXComponent类,设置属性值。 六、实例 package cn.jcl.test; import com.jacob.activeX.ActiveXComponent; import com.jacob.com.ComThread; import com.jacob.com.Dispatch; import com.jacob.com.Variant; public class exportPicToWord { ActiveXComponent msWordApp = null; Dispatch document = null; public exportPicToWord() { if (msWordApp == null) { ComThread.InitSTA(); msWordApp = new ActiveXComponent("Word.Application"); } } //TODO 设置文档是否前台打开word public void setVisible(boolean visible) { msWordApp.setProperty("Visible", new Variant(visible)); // 与上一句作用相同 // Dispatch.put(msWordApp, "Visible", new Variant(visible)); } //TODO 创建一个新的文档 public void createNewDocument() { // document表示word的所有文档窗口,(word是多文档窗口应用程序) Dispatch documents = Dispatch.get(msWordApp, "Documents").toDispatch(); // 调用add方法来创建一个新的文档 document = Dispatch.call(documents, "Add").toDispatch(); } //TODO 向文档中插入格式化文档 public void insertFormatStr() { Dispatch selection = Dispatch.get(msWordApp, "Selection").toDispatch(); // 得到段落格式对象 Dispatch paragraphFormat = Dispatch.get(selection, "ParagraphFormat").toDispatch(); // 设置正文的对齐方式:1.置中,2.靠右,3.靠左 Dispatch.put(paragraphFormat, "Alignment", "1"); // 得到字体对象 Dispatch font = Dispatch.get(selection, "Font").toDispatch(); // 设置黑体 Dispatch.put(font, "Bold", new Variant(true)); // 字型颜色(1,0,0,0=>红色 1,1,0,0=>棕色) Dispatch.put(font, "Color", "1,0,0,0"); // 设置斜体 Dispatch.put(font, "Italic", new Variant(true)); // 设置宋体 Dispatch.put(font, "Name", new Variant("宋体")); // 设置大小 Dispatch.put(font, "Size", new Variant(12)); // 写入标题内容 Dispatch.call(selection, "TypeText", "标题"); // 空一行段落 Dispatch.call(selection, "TypeParagraph"); Dispatch.put(paragraphFormat, "Alignment", "3"); Dispatch.put(font, "Color", "1,1,0,0"); Dispatch.put(selection, "Text", " 第一段内容"); Dispatch.call(selection,"MoveRight"); // 空一行段落 Dispatch.call(selection, "TypeParagraph"); Dispatch.put(selection, "Text", " 第二段内容"); Dispatch.call(selection,"MoveRight"); } //TODO 向文档中添加文字. public void insertText(String text) { // 得到选中的内容,如果创建一个新的文档,因里面没有内容,光标应在开头.
