[java]
/**
* 通过HttpCient调用报告服务器的方法生成报告 DOC
*/
public String createDoc() throws Exception {
//定义放回成功与否的判断码
String prMsg="";
// 获取当前登录的用户
UserVo userVo = CommonUtils.getUserMessage();
//获取模版类型
docType = Struts2Utils.getParameter("docType");
//重新创建文档
String creatOrnot = Struts2Utils.getParameter("creatOrnot");
//获取组组编号参数
workgroupId = Struts2Utils.getParameter("workgroupId");
//获取评估用例实例ID参数
evtcaseInstId = Struts2Utils.getParameter("evtcaseInstId");
if(CommonUtils.isNotNull(docType)){
//获取项目Id
projectId = Struts2Utils.getParameter("projectId");
if(!CommonUtils.isNotNull(projectId)){
if(CommonUtils.isNotNull(this.getIdFromSession("PM_PROJECTID"))){
projectId = this.getIdFromSession("PM_PROJECTID").toString();
}else{
Struts2Utils.getRequest().setAttribute("msg", "请先选择项目!");
}
}
if(CommonUtils.isNotNull(projectId)){
prMsg = infoSystemDescService.downloadFileByUrl(projectId, userVo.getUserId(), workgroupId, evtcaseInstId, docType, creatOrnot);
}
}
return "docList";
}
注：在我贴出来的代码中，能看懂就行了，有些不用管他（可能是其他业务方面的判断）,关于最后返回的prMsg---代表各种状态 主要表示成功与否或者是出错的信息。
接着我贴出service层的方法downloadFileByUrl
[java]
/prep/pp/ppre name="code" class="java"pre name="code" class="java"/**

zip包，然后自动下载下来
1.预先定义好模板
2.界面输入相关参数
3.解析模板生成代码并下载
最后放出源代码：

Freemarker是一个模板框架。我们可以通过Freemarker进行代码生成或页面的静态生成。 现在简单的说一下怎样使用Freemarker Freemarker的主要生成类
public boolean generate(String templateFileName, Map data,
String fileName) {
try {
//取得模板的位置
String templateFileDir=templateFileName.substring(0, templateFileName.lastIndexOf("/"));
//取得模板的名字
String templateFile=templateFileName.substring(templateFileName.lastIndexOf("/"), templateFileName.length());
//取得生成文件的路径
String genFileDir=fileName.substring(0, fileName.lastIndexOf("/"));
Template template = ConfigurationHelper.getConfiguration(templateFileDir).getTemplate(templateFile);
File fileDir=new File(genFileDir);
org.apache.commons.io.FileUtils.forceMkdir(fileDir);
File output = new File(fileName);
if(output.exists()){
//如何代码已存在不重复生成
return false;
}
Writer writer = new FileWriter(output);
template.process(data, writer);
writer.close();
} catch (TemplateException e) {
e.printStackTrace();
return false;
} catch (IOException e) {
e.printStackTrace();
return false;
}
return true;
}
代码中的Map 是模板所需要的数据，我们可以通过面向对像的方法把数据存在模板中public boolean genDaoInterface(String fileName){
DaoModel daoModel=new DaoModel();
//设置Dao实现类的包名
daoModel.setPackageName(DaoConstant.PACKAGE);
//取得接口名
String className=StringUtils.substringBefore(fileName,".");
//设置接口名
daoModel.setClassName(className);
MapString, Object data = new HashMapString, Object();
data.put("model", daoModel);
//设置生成的位置
String filePath=new String("src/"+package2path(DaoConstant.PACKAGE)+"/"+fileName);
//代码生成
return super.generate(DaoConstant.INTERFACE_TEMPLATE, data, filePath);
}
data.put("model", daoModel);由这句代码可看出我们将可以在模板中直接调用这些数据package ${model.packageName};
public interface ${model.className} extends BaseHibernateDao {
}
