嘿，我嘗試運行此應用程序時出現問題。我沒有收到編譯錯誤，只是運行時錯誤。我想我錯過了一些東西，但我不確定，有人能幫我理解我出錯的地方嗎？從我所看到的applicationContext.xml中的sessionFactory bean沒有被創建。這裏是我的代碼：Spring Maven項目
主要
package com.apress.flexjava.usermanager.business;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.apress.flexjava.usermanager.dao.UserDao;
import com.apress.flexjava.usermanager.model.User;
public class Main {
public static void main(String [] args){
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
UserDao userDao = (UserDao)context.getBean("userDao");
List<User> users = userDao.findAll();
for (User user : users) {
System.out.println(user.getForename() + " " + user.getSurname());
}
}
}
______________________________________________________________________________________
userDAO的
package com.apress.flexjava.usermanager.dao;
import java.util.List;
import com.apress.flexjava.usermanager.model.User;
public interface UserDao {
List<User> findAll();
}
__________________________________________________________________________________
UserDaoSpringJdbcImpl
package com.apress.flexjava.usermanager.dao.jdbc;
import java.util.List;
import org.springframework.jdbc.core.simple.ParameterizedBeanPropertyRowMapper;
import org.springframework.jdbc.core.simple.SimpleJdbcDaoSupport;
import com.apress.flexjava.usermanager.dao.UserDao;
import com.apress.flexjava.usermanager.model.User;
public class UserDaoSpringJdbcImpl extends SimpleJdbcDaoSupport implements UserDao{
public List<User> findAll(){
String sql= "SELECT * FROM users";
return getSimpleJdbcTemplate().query(sql, ParameterizedBeanPropertyRowMapper.newInstance(User.class));
}
}

您在運行時缺少jar或存在版本衝突等。該錯誤告訴您什麼類def導致了問題。 – 2012-04-18 04:47:49
