索引处缺少 IN 或 OUT 参数:: 2 ERROR with Mybatis

Question

我的应用程序中有一个像这样的 Mapper class，它试图调用数据库中的过程，我检查了 3000 次类型和位置 og 参数是否正确，但它抛出和 sqlException，现在我将向您展示映射器的代码

@Mapper
public interface HoraFechaExtractoMapper {

    @Select(value="{ CALL PACKAGE.PROCEDURE("
            + "#{P_tpno, mode=IN, jdbcType=VARCHAR},"
            + "#{Registro.pPeriodicidad, mode=OUT, jdbcType=VARCHAR},"
            + "#{Registro.pHora, mode=OUT, jdbcType=VARCHAR},"
            + "#{Registro.pDia, mode=OUT, jdbcType=NUMERIC})}")
    public void getHoraFechaExtracto(@Param("P_tpno") String p_tpno,@Param("Registro") Registro registro);
}

我的 Registro Class 是 methos Mapper 的参数，就像这样

public class Registro implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 2014497735552490495L;
    
    /** The p periodicidad. */
    @JsonProperty("p_periodicidad")
    private String pPeriodicidad;
    
    /** The p hora. */
    @JsonProperty("p_hora")
    private String pHora;
    
    /** The p dia. */
    @JsonProperty("p_dia")
    private Integer pDia;

    /**
     * Gets the p periodicidad.
     *
     * @return the p periodicidad
     */
    public String getpPeriodicidad() {
        return pPeriodicidad;
    }

    /**
     * Sets the p periodicidad.
     *
     * @param pPeriodicidad the new p periodicidad
     */
    public void setpPeriodicidad(String pPeriodicidad) {
        this.pPeriodicidad = pPeriodicidad;
    }

    /**
     * Gets the p hora.
     *
     * @return the p hora
     */
    public String getpHora() {
        return pHora;
    }

    /**
     * Sets the p hora.
     *
     * @param pHora the new p hora
     */
    public void setpHora(String pHora) {
        this.pHora = pHora;
    }

    /**
     * Gets the p dia.
     *
     * @return the p dia
     */
    public Integer getpDia() {
        return pDia;
    }

    /**
     * Sets the p dia.
     *
     * @param pDia the new p dia
     */
    public void setpDia(Integer pDia) {
        this.pDia = pDia;
    }

}

但是Mybatis在准备语句的时候抛出这个错误

### The error occurred while setting parameters
### SQL: { CALL PACKAGE.PROCEDURE(?,?,?,?)}
### Cause: java.sql.SQLException:  Missing IN or OUT parameter at index::  2
    Caused by: org.apache.ibatis.exceptions.PersistenceException:

很可能是mapper的错误，但是我找不到错误，也许你能看到它

Answer 1

也许你需要

@Options(statementType = StatementType.CALLABLE)

在 Select 注释之后

索引处缺少 IN 或 OUT 参数:: 2 ERROR with Mybatis

Missing IN or OUT parameter at index:: 2 ERROR with Mybatis

java

sql

spring
