Answer 2

可能是你对应的类ssh.hbl.action.bookAction中没有定义引用 的bookservice 这个bean的set get 方法,
你把java代码贴上来看下

Answer 3

package ssh.hbl.action;import java.util.Iterator;
import java.util.List;import ssh.hbl.model.Book;
import ssh.hbl.service.impl.BookService;import com.opensymphony.xwork2.ActionSupport;public class bookAction extends ActionSupport {

private BookService bookservice;

public String ListBook()
{
List<Book> list=bookservice.listBook();
//for(Iterator it=list.iterator();)
for (Iterator it=list.iterator();it.hasNext();)
{
Book b=(Book)it.next();
System.out.println("result="+b.getBookid()+"---"+b.getBookname()+"---"+b.getAuthor());
}
return "success";
}
public String GetBook()
{
Book b=bookservice.getBook(14);
System.out.println("result="+b.getBookid()+"---"+b.getBookname()+"---"+b.getAuthor());
return "success";

}
public String UpdateBook()
{ System.out.println("更新成功");
return "success";

}
public String DeleteBook()
{
bookservice.delBook(14);
return "success";

}
public String AddBook()
{
Book b=new Book();
b.setBookid(59);
b.setAuthor("hbl");
b.setBookname("hbl");
b.setPrice("hbl");
bookservice.updateBook(b);
return "success";
}
public BookService getBookservice() {
return bookservice;
}
public void setBookservice(BookService bookservice) {
this.bookservice = bookservice;
}
}

Answer 4

上面的一个帖错了,下面是 bookactionpackage ssh.hbl.action;import java.util.Iterator;
import java.util.List;import ssh.hbl.model.Book;
import ssh.hbl.service.impl.BookService;import com.opensymphony.xwork2.ActionSupport;public class bookAction extends ActionSupport {

private BookService bookservice;

public String ListBook()
{
List<Book> list=bookservice.listBook();
//for(Iterator it=list.iterator();)
for (Iterator it=list.iterator();it.hasNext();)
{
Book b=(Book)it.next();
System.out.println("result="+b.getBookid()+"---"+b.getBookname()+"---"+b.getAuthor());
}
return "success";
}
public String GetBook()
{
Book b=bookservice.getBook(14);
System.out.println("result="+b.getBookid()+"---"+b.getBookname()+"---"+b.getAuthor());
return "success";

}
public String UpdateBook()
{
Book b=new Book();
b.setBookid(14);
b.setAuthor("hbl");
b.setBookname("hbl");
b.setPrice("hbl");
bookservice.updateBook(b);
return "success";

}
public String DeleteBook()
{
bookservice.delBook(14);
return "success";

}
public String AddBook()
{
Book b=new Book();
b.setAuthor("hbl");
b.setBookname("hbl");
b.setPrice("123");
bookservice.addBook(b);
return "success";
}
public BookService getBookservice() {
return bookservice;
}
public void setBookservice(BookService bookservice) {
this.bookservice = bookservice;
}
}

Answer 5

如果不用事务,用listbook这个方法可以读到,如果用了事务就读不到了,更别说更新和删除了
