Коллекция Mapped Statements не содержит значения для getFieldData

/ 10 апреля 2019

Нет проблем при запуске приложения, но во время выполнения, когда вызывается API, всплывающее окно с моей ошибкой.

Я уже пробовал другие решения, представленные здесь другими разработчиками, в переполнении стека, но не повезло, и ошибка все та же.

Вот мой код:

FiedlDataDaoImpl.java 

@Component
public class FieldDataDaoImpl implements FieldDataDao{

    @Autowired
    private SqlSession sqlSession;

    @Override
    public FieldData getFieldData() throws SQLException, Exception {
        FieldData result = new FieldData();

        try {
            result = this.sqlSession.selectOne("getFieldData");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }
}

mybatis-config.xml 

<configuration>
    <settings>
        <setting name="jdbcTypeForNull" value="NULL" />
    </settings>
    <typeAliases>
        <!-- <package name="com.pnb.allianz.bir.model" /> -->
        <typeAlias alias="FieldData" type="com.pnb.allianz.jdt.model.FieldData"/>
    </typeAliases>
    <mappers>
        <mapper resource="xml-mappers/FieldData.xml" />
    </mappers>
</configuration>

FieldData.xml 

<mapper>
     <resultMap id="FieldDataResultMap" type="FieldData">
        <result column="LF2S_TRAN_TYPE"         property="transactionType"/>
        <result column="LF2S_DISTRIBUTION"      property="distribution"/>
        <result column="LF2S_REPORT_TYPE"   property="reportType"/>
    </resultMap>

    <select id="getFieldData" resultMap="FieldDataResultMap" >
        SELECT * FROM LF2S_MR_PARAMETERS
        WHERE rownum =1
    </select>
</mapper>

GenerateJdtController.java 

@Controller
public class GenerateJdtController {

    @Autowired
    FieldDataService fieldDataService;

    @RequestMapping("/generate-gdt")
    ModelAndView getView(Model model) throws SQLException, Exception {
        model.addAttribute("wc_msg", fieldDataService.getFieldData());
        ModelAndView mv = new ModelAndView("index");
        return mv;
    }
}

.. и ошибка происходит следующим образом, когда http://localhost:8080/generate-gdt вызывается

Вашему мапперу нужно namespace. 

<!-- FieldData.xml -->
<mapper namespace="FieldData">

// FiedlDataDaoImpl.java
result = this.sqlSession.selectOne("FieldData.getFieldData");

Подробнее см. документ .
