代码如下：

@Component
public class Employee {
private Long id; //员工id
private String empId; //员工编号
private String empName; //员工姓名
private int sex; //员工性别
.................................
@Repository
public interface EmployeeDao {
public int add(Employee employee);
public int edit(Employee employee);
public int delete(String ids);
public List<Employee> findList(Map<String, Object> queryMap);
public int getTotal(Map<String, Object> queryMap);
}
@RequestMapping(value="/add",method=RequestMethod.POST)
@ResponseBody
public Map<String, String> add(Employee employee){
Map<String, String> ret = new HashMap<String, String>();
if(employee == null) {
ret.put("type", "errror");
ret.put("msg", "请正确输入添加员工的相关信息！");
}
if (StringUtils.isEmpty(employee.getEmpId())) {
ret.put("type", "error");
ret.put("msg", "请填写员工编号！");
}
if(StringUtils.isEmpty(employee.getEmpName())) {
ret.put("type", "error");
ret.put("msg", "请填写员工姓名！");
}
if(StringUtils.isEmpty(employee.getSex())) {
ret.put("type", "error");
ret.put("msg", "请选择员工性别");
}
ret.put("type", "success");
ret.put("msg", "员工信息登记成功！");
return ret;
}
}

mapper 如下：

<mapper namespace="com.ischoolbar.programmer.dao.admin.EmployeeDao">
<!-- 添加员工 -->
<insert id="add" parameterType="Employee">
insert into emp(id,empId,empName,sex) values(null,#{empId},#{empName},#{sex})
</insert>

<!-- 分页获取员工列表 -->
<select id="findList" parameterType="Map" resultType="Employee">
	select * from emp 
	<if test="empName != null">
		where empName like '%${empName}%' 
	</if>
	<if test="offset != null and pageSize != null">
		limit #{offset},#{pageSize}
	</if>
</select>
<!-- 获取符合结果的总记录数 -->
<select id="getTotal" parameterType="Map" resultType="Integer">
	select count(*) from emp 
	<if test="empName != null">
		where empName like '%${empName}%' 
	</if>
</select>

</mapper>
