    private  String gender;
    private String tel;
    private  String address;
    private Date birth;

dao层

public List<Person> selectUser(@Param("user")Person person,@Param("first") Integer first,@Param("last") Integer last);

mapper.xml

<select id="selectUser"  resultType="cn.szh.bean.Person">
    select * from person
    <where>
    <if test="id != null">AND Id=#{id}</if>
    <if test="name != null">AND Name=#{name}</if>
    <if test="address !=null">AND Address=#{address}</if>
    </where>
    limit #{first},#{last}
</select>

serviceimp层

@Override
public List<Person> selectUser(Person person,Integer currentPage, Integer size) {
    List<Person> personList = userDao.selectUser(person,(currentPage - 1) * size, size);
    return personList;
}

controller层

@RequestMapping("select")
public String selectUser(Model model,Person person,Integer currentPage,Integer size){
    List<Person> personList = userService.selectUser(person,currentPage,size);
    model.addAttribute("persons",personList);
    return "hello";
}

报错

 Parameter 'id' not found. Available parameters are [last, param3, user, param1, first, param2]

Answer 1

user.id 

@Param("user")Person person

person的属性都用user.*来取
