通过java代码实现调用excel当中的宏的操作。

最近做的项目是自动化生成基金的交易合同的操作。然后就想着通过java代码去操作Excel当中的宏按钮，然后生成word版本的合同的操作。

具体的java代码如下：

import org.junit.Assert;
import org.junit.Test;

public class ExcelToolsServiceTest {

    private ExcelToolsService service;

    @Test
    public void testMacro() {
        try {
            String path = "C:/Users/admin.admin-PC.000/Desktop/vb/合并的模板/合同模板.xlsm";
            service = new ExcelToolsService();
            service.execMacro(path, "文本替换.生成文档");
        } catch (Exception e) {
            e.printStackTrace();
            Assert.fail();
        }
    }

}

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;

public class ExcelToolsService {

public void execMacro(String excelPath, String macroName, Variant... params) throws Exception {


ActiveXComponent excel = null;
Dispatch workbooks = null;
Dispatch workbook = null;
long start = System.currentTimeMillis();
System.out.println(start);

try {
ComThread.InitSTA();

excel = new ActiveXComponent("Excel.Application");
workbooks = excel.getProperty("Workbooks").toDispatch();
workbook = Dispatch.call(workbooks, "Open", excelPath).toDispatch();
if (null == params || params.length < 1) {
Dispatch.call(excel, "Run", new Variant(macroName));
} else {
Dispatch.call(excel, "Run", new Variant(macroName), params);
}
Dispatch.call(workbook, "Save");
} catch (Exception e) {
e.printStackTrace();
} finally {
if (null != workbook) {// 关闭文档
Dispatch.call(workbook, "Close", new Variant(false));
}
if (null != workbooks) {
Dispatch.call(workbooks, "Close");
}
if (null != excel) {
excel.invoke("Quit", new Variant[] {});
}

// 关闭Excel进程
ComThread.Release();

long end = System.currentTimeMillis();
System.out.println("处理文件[{}]宏[{}],共耗时{}s" + excelPath + macroName
+ ((end - start) / 1000 + 1));
}
}

}

至此实现了通过Excel的宏自动化的生成基金的合同的操作。
