[FIXED] I can't put a HashMap object in the MyBatis parameter

Issue

I'm trying use a HashMap object to look up ids and passwords in database, but I can't. I can only get error message as follows:

Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.type.TypeException: Could not set parameters for mapping: ParameterMapping{property='name', mode=IN, javaType=class java.lang.Object, jdbcType=null, numericScale=null, resultMapId='null', jdbcTypeName='null', expression='null'}. Cause: org.apache.ibatis.type.TypeException: Error setting null for parameter #1 with JdbcType OTHER . Try setting a different JdbcType for this parameter or a different jdbcTypeForNull configuration property. Cause: java.sql.SQLException: 부적합한 열 유형: 1111

I set my MyBatis mapper as follows:

  <select id="selectOneByNTB" parameterType="hashMap" resultType="custDto">
    select * from Customer_info where cust_name = #{name} and cust_telephone=#{telephone} and cust_birthday=#{birthday}
  </select>

And, I think it's ok with my controller and dao, but I'll attach it.

@RequestMapping(value="/findId", method=RequestMethod.POST)
    public String findId(@ModelAttribute Customer_infoDto cuDto, HttpServletResponse response) throws Exception {
        
        HashMap<String, String> map = new HashMap<String, String>();    
        map.put("name", cuDto.getCust_name());
        map.put("telephone", cuDto.getCust_telephone());
        map.put("birthday", cuDto.getCust_birthday());
        
        
        System.out.println("name: "+map.get("name"));
        System.out.println("telephone: "+map.get("telephone"));
        System.out.println("birthday: "+map.get("birthday"));
                
        
        String cust_id = cudao.selectOneByNTB(map).getCust_id();
        response.setCharacterEncoding("UTF-8");
        response.setContentType("text/html; charset=UTF");
        PrintWriter out = response.getWriter();
        out.println("<meta charset='UTF-8'><script>alert('Your ID is "+ cust_id +"'); history.go(-1);</script>");
        out.flush();        
        return "redirect:/findIdAndPw";
    }

public Customer_infoDto selectOneByNTB(HashMap<String, String> map) {
        System.out.println("name"+((map.get("cust_name"))));
        return ss.selectOne(NameSpace + "selectOneByNTB");
    }

I checked the HashMap variable in the controller and dao correctly print their items.

So, I think the mapper is the problem. Is there anything wrong in my mapper? or any other problems with my other codes?

FYI, I'll put my pom.xml dependecies,

Solution

In the selectOneByNTB() method, you need to pass the HashMap parameter as the second argument of selectOne().

public Customer_infoDto selectOneByNTB(HashMap<String, String> map) {
  System.out.println("name"+((map.get("cust_name"))));
  return ss.selectOne(NameSpace + "selectOneByNTB", map);
}
