struts2 以报表输出的问题
struts2 spring hibernate3 eclipse3.3.2 相关问题
在做 报表输出的时候 把按照条件搜索出来的数据 以 PDF CSV的形式输出 出现如下错误：
下面给出部分代码：
model层存放的是hibernate 生成的与数据库对应的两个文件 这里不给出 给出 表的字段：
id name author publish time isbn page content
dao层
public class EmpbookDaoImpl extends HibernateDaoSupport implements EmpbookDao {
@SuppressWarnings("unchecked")
@Override
public List<Empbook> getEmpbook() {
// TODO Auto-generated method stub
String sql = "from Empbook empbook";
List<Empbook> list = this.getHibernateTemplate().find(sql);
return list;
}
@SuppressWarnings("unchecked")
@Override
public List getQuery() {
// TODO Auto-generated method stub
String sql = "from Empbook empbook";
List<Empbook> list = this.getHibernateTemplate().find(sql);
return list;
}
}
service 层
public class EmpbookServiceImpl implements EmpbookService {
EmpbookDao empbookDao;
@Override
public List<Empbook> getEmpbook() {
// TODO Auto-generated method stub
return empbookDao.getEmpbook();
}
public EmpbookDao getEmpbookDao() {
return empbookDao;
}
public void setEmpbookDao(EmpbookDao empbookDao) {
this.empbookDao = empbookDao;
}
@SuppressWarnings("unchecked")
@Override
public List getQuery() {
// TODO Auto-generated method stub
return empbookDao.getQuery();
}
}
action 层
public class EmpbookAction extends ActionSupport {
EmpbookService empbookService;
// Empbook Empbook;
private String id;
private String name;
private String author;
private String publish;
private String time;
private String isbn;
private int page;
private String content;
//get set 方法省略
private List<Empbook> availableItems;
public String Display() throws Exception{
Empbook p1 = new Empbook("sdf","asd","sds","sdsd","sds","ds",50,"sdf");
Empbook p2 = new Empbook("wqe","www","sddss","sdadsd","swqewqds","dqwes",510,"sdfqwewq");
Empbook p3 = new Empbook("qwe","awd","ssds","sdwqewqsd","swqewqeds","dqweqws",150,"swqewqdf");
availableItems = new ArrayList<Empbook>();
availableItems.add(p1);
availableItems.add(p2);
availableItems.add(p3);
try {
String reportSource;
reportSource=ServletActionContext.getServletContext().getRealPath("/jasper/jasper_template.jrxml");
File parent = new File(reportSource).getParentFile();
JasperCompileManager.compileReportToFile(reportSource,
new File(parent, "compiled_jasper_template.jasper").getAbsolutePath());
}catch (Exception e) {
e.printStackTrace();

请帮帮忙 着急要结果
如果是 多个表 a b c 相关联 按照多个条件进行检索 把结果在jsp 显示出来 并以 PSD CSV 形式输出 数据是从数据库中查询得到的 应该如何修改呢？
