Question

我只是想了解Soap WS。所以我只写下一些简单的类。但是当我在GlassFish中部署此应用程序并对其进行测试时，服务器将返回java.lang.reflect.InvocationTargetException。谁能说出问题是什么？

@WebService
public class AuthorWS {
AuthorService authorService = new AuthorService();

@WebMethod
public Author getAuthorById(int authorId) {
    return authorService.getAuthorById(authorId);
}

@WebMethod
public ArrayList<Author> getAllAuthors() {
    return authorService.getAllAuthors();
}
}

服务类：

public class AuthorService {
AuthorDAO authorDAO = new AuthorDAO();
public Author getAuthorById(int authorId){

    return authorDAO.getAuthorById(authorId);
}
public ArrayList<Author> getAllAuthors(){
    return authorDAO.getAllAuthors();
}
}

DAO班级：

public class AuthorDAO {

public Author getAuthorById(int authorId){
    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Criteria criteria = sessionFactory.openSession().createCriteria(Author.class);
    criteria.add(Restrictions.eq("authorId", authorId));
    return (Author) criteria.uniqueResult();

}
public ArrayList<Author> getAllAuthors(){
    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Criteria criteria = sessionFactory.openSession().createCriteria(Author.class);
    return (ArrayList<Author>) criteria.list();
}

例外：

问题出在服务器端，正如您可以从堆栈跟踪中看到的那样

: Client received SOAP Fault from server:
 com.sun.enterprise.container.common.spi.util.InjectionException: 
Error creating managed object for class: 
class com.hojat.LibrarySoapWS.ws.AuthorWS 
Please see the server log to find more detail regarding exact cause of the failure.

请检查服务器日志。

调用SOAP WS时java.lang.reflect.InvocationTargetException的原因是什么？
