controller代码：
@RequestMapping(value = "/manager/message/{type}", method = RequestMethod.POST)
public String selectUserName(Model m, @PathVariable("type") String type) {
m.addAttribute("name", messageService.getUserName(type));
return "manager/message/add";
}
service代码：
public String getUserName(String type);
实现service代码
@Transactional(readOnly = true)
public String getUserName(String type) {
Query query ;
if("2".equals(type)){
query = userDao.createQuery("from UsersEntity c where c.userType = 0");
}else{
query = userDao.createQuery("from UsersEntity c where c.userType = 0 and c.type = ?",type);
}
List ls = query.list();
List userNames = Lists.newArrayList();
for (int i = 0; i < ls.size(); i++) {
UsersEntity entity = ls.get(i);
UserVO vo = new UserVO();
DozerBeanMapperSingletonWrapper.getInstance().map(entity, vo);
userNames.add(vo.getUserName());
}
String userName = userNames.toString();
String name = userName.substring(1, userName.length()-1);
return name;
}
