MockMVC not mapping query parameters

When I test REST API endpoints using POSTMAN, It works fine. This is the console message.

But when I try to test same endpoints using jUnit with MockMVC, it gets parameters but cannot map in query.

Here is my testcase code.

    public MockMvc mockMvc;

public void testGetMethod_param(String url, UnaryOperator<MockHttpServletRequestBuilder> operator)
            throws Exception {
        mockMvc.perform(operator.apply(get(url))).andDo(print()).andExpect(status().isOk());
    }




 @ContextConfiguration("file:src/main/webapp/WEB-INF/**/*.xml")
public class BoardControllerTest extends HttpRequestTestMethod implements CoreParameters, AdapterServiceParameters{

    @Autowired
    public BoardController boardController;


    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders.standaloneSetup(boardController).build();
    }
    @Test
    public void savecmt() throws Exception {
        testGetMethod_param("/Board.do", builder->builder
                .param("cmd", "saveCmt")
                .param("enterCd", enterCd)
                .param("sabun", sabun)
                .param("bbsCd", bbsCd)
                .param("bbsSeq", bbsSeq)
                .param("comments", comments));
    }

If I deliberately set enterCd to NULL, I get this following message.

[2018-11-15 11:06:02] [ERROR]『oracle.jdbc.driver.T4CTTIoer:processError(439)』

ORA-01400: cannot insert Null in ("EHR_ISU4"."TSYS730"."ENTER_CD")

But as attached above, when using jUnit, all parameters are set to "?"

Query = [org.springframework.dao.DataIntegrityViolationException: PreparedStatementCallback; SQL [

                        INSERT INTO TSYS730(ENTER_CD, SABUN, BBS_SEQ, COMMENTS_SEQ, COMMENTS, CHKDATE, CHKID, BBS_CD)

; nested exception is java.sql.SQLIntegrityConstraintViolationException: ORA-01400: cannot insert Null in ("EHR_ISU4"."TSYS730"."ENTER_CD") 
] 

Can anyone tell me what is wrong here? Any help would be greatly appreciated.
