检索数据时出错

Question

我的table:

CREATE TABLE [dbo].[R_ACADEMIE](
    [ID_ACADEMIE] [dbo].[IDENTIFIANT] NOT NULL,
    [LC_ACADEMIE_CODE] [dbo].[LIBELLE_COURT] NOT NULL,
    [LM_ACADEMIE_LIBELLE] [dbo].[LIBELLE_MOYEN] NOT NULL
) ON [PRIMARY]

我的结果图：

<resultMap class="business.bo.AcademieBO"
    id="AcademieBOResult">
    <result column="ID_ACADEMIE" jdbcType="NUMERIC"
        property="idAcademie" />
    <result column="LC_ACADEMIE_CODE" jdbcType="VARCHAR"
        property="lcAcademieCode" />
    <result column="LM_ACADEMIE_LIBELLE" jdbcType="VARCHAR"
        property="lmAcademieLibelle" />
</resultMap>

AcademiBO.java:

import java.io.Serializable;
import java.math.BigDecimal;

public class AcademieBO implements Serializable{

    /**

    private static final long serialVersionUID = 1L;

    /**

    private BigDecimal idAcademie;

    /**

     */
    private String lcAcademieCode;

    /**
     * <code>lmCivLibelle</code> the lmCivLibelle
     */
    private String lmAcademieLibelle;

    public BigDecimal getIdAcademie() {
        return idAcademie;
    }

    public void setIdAcademie(BigDecimal idAcademie) {
        this.idAcademie = idAcademie;
    }

    public String getLcAcademieCode() {
        return lcAcademieCode;
    }

    public void setLcAcademieCode(String lcAcademieCode) {

    }

    public void setLmAcademieLibelle(String lmAcademieLibelle) {
        this.lmAcademieLibelle = lmAcademieLibelle;
    }

你不能在 iBatis 中使用 select *，你需要给出所有的列名以便 iBatis 能够将正确的列映射到正确的对象属性.

   <select id="listAll" resultMap="AcademieBOResult">
        select ID_ACADEMIE, LC_ACADEMIE_CODE, LM_ACADEMIE_LIBELLE from dbo.R_ACADEMIE
        ORDER BY ID_ACADEMIE ASC
    </select>

在单独的工具（SQL 开发人员）中再次检查您的 SQL 请求以确保其有效。我不太了解您的创建 table 脚本：我不熟悉 SQL 服务器，您重新定义列名的方式以及没有列类型的事实对我来说似乎很奇怪，也许问题出在这里......
