为什么我的ssh框架用get方法查询出来的数据出id外，其他的数据都是null

这是我的spring4集成hibernate5的配置

这是我的事物管理配置

这是baseDaoImpl类实现了baseDao接口
package com.skill.dao;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository("baseDao")
public class BaseDaoImpl implements BaseDao
{

private SessionFactory sessionFactory;

@Autowired
public void setSessionFactory(SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}

public SessionFactory getSessionFactory()
{
return sessionFactory;
}

public Session getCurrentSession()
{
return getSessionFactory().getCurrentSession();
}

public <T> T getEntityBy(Class<T> T,Integer id)
{
return getCurrentSession().get(T, id);
}

userDaoImpl 继承了baseDaoImpl 实例userDao接口，userDao接口继承BaseDao接口
package com.skill.dao.userDao.impl;

import org.springframework.stereotype.Repository;

import com.skill.dao.BaseDaoImpl;
import com.skill.dao.userDao.UserDao;
import com.skill.model.User;

@Repository("userDao")
public class UserDaoImpl extends BaseDaoImpl implements UserDao
{
@Override
public User getUserBy(Integer id)
{
return super.getEntityBy(User.class, id);
}
}

userServiceImpl实现类调用userService
package com.skill.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.skill.dao.userDao.UserDao;
import com.skill.model.User;
import com.skill.service.UserService;

@Service("userService")
public class UserServiceImpl implements UserService
{
@Autowired
private UserDao userDao;
@Override
public User findUserBy(Integer id)
{
return userDao.getUserBy(id);
}
}

这个是写的测试方法
package com.skill.test;

import org.jboss.logging.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.skill.model.User;
import com.skill.service.UserService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring.xml"})
public class FunctionTest
{
private Logger logger = Logger.getLogger(FunctionTest.class);
@Autowired
UserService userService;
@Test
public void testJDBC()
{
User user = userService.findUserBy(2);
logger.info("查询结果是：id--->"+user.getId()+"\tname--->"+ user.getUserName());
}
}

然而实际的测试结果是这样的
INFO: 查询结果是：id--->2 name--->null

有ID却没有name，当我在事物中把readonly去掉时，hibernate会先差一遍接着马上就update了。
Hibernate:
select
user0_.ID as ID1_0_0_,
user0_.PASSWORD as PASSWORD2_0_0_,
user0_.USERNAME as USERNAME3_0_0_
from
USER_TB user0_
where
user0_.ID=?
Hibernate:
update
USER_TB
set
PASSWORD=?,
USERNAME=?
where
ID=?
在事物中加上readonly=true后
不会update，但是还是没有结果，哪位大哥帮帮我，看看是哪里的问题！
