iBATIS SQL Apache XML DAO

com.ibatis.sqlmap.client.SqlMapException: There is no statement named User.login in this SqlMap.

SqlMapConfig.xml代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
	<settings cacheModelsEnabled="true" enhancementEnabled="true" lazyLoadingEnabled="true"
		maxRequests="32" maxSessions="10" maxTransactions="5" useStatementNamespaces="true" />
	<sqlMap resource="com/lhq/prj/bms/po/xml/User.xml" />
</sqlMapConfig>

UserDao.java 代码如下：

package com.lhq.prj.bms.dao.impl;

import java.util.List;

import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

import com.lhq.prj.bms.core.Page;
import com.lhq.prj.bms.dao.IUserDao;
import com.lhq.prj.bms.po.User;

/**

 */
public class UserDao extends SqlMapClientDaoSupport implements IUserDao {

	public Integer deleteById(Integer userId) {
		// TODO Auto-generated method stub
		return getSqlMapClientTemplate().delete("User.deleteById", userId);
	}

	public int findByCount(Page page) {
		// TODO Auto-generated method stub
		return (Integer) getSqlMapClientTemplate().queryForObject("User.findByCount", page);
	}
	
	public List findByExample(User user) {
		// TODO Auto-generated method stub
		return getSqlMapClientTemplate().queryForList("User.findByExample", user);
	}

	public Object saveUser(User user) {
		// TODO Auto-generated method stub
		return getSqlMapClientTemplate().insert("User.save", user);
	}

	public Integer update(User user) throws Exception {
		// TODO Auto-generated method stub
		return getSqlMapClientTemplate().update("User.update", user);
	}

	public List findByPage(Page page) {
		// TODO Auto-generated method stub
		return getSqlMapClientTemplate().queryForList("User.findByPage", page);
	}

	public User login(User user) {
		// TODO Auto-generated method stub
		return (User) getSqlMapClientTemplate().queryForObject("User.login", user);
	}

}

User.xml代码如下：

错误原因：User.xml中没有定义命名空间
<sqlMap namespace="User">
