Question

早上好，我是Spring Boot的新手，我正在执行rest服务，该服务必须调用存储在数据库中的过程，问题是您收到手机并必须返回代码和结果，如下所示：

这是我的代码：

主类

package com.app.validacion;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

控制器

package com.app.validacion.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;


import com.app.validacion.dao.DriverBonificadosRepository;
import com.app.validacion.entity.RespuestaVo;

@RestController
public class DriverBonificadosController {

    @Autowired
    private DriverBonificadosRepository dao;

    @GetMapping("/service/{movil}")
    public RespuestaVo  ConsultarMovil(@PathVariable String movil) {
        return dao.validarClienteBonifiado(movil);

    }
}

存储库

package com.app.validacion.dao;

import org.springframework.data.jpa.repository.query.Procedure;
import org.springframework.data.repository.CrudRepository;

import com.app.validacion.entity.DriverBonificados;
import com.app.validacion.entity.RespuestaVo;

public interface DriverBonificadosRepository extends CrudRepository<DriverBonificados, Integer> {

    @Procedure(procedureName="ValidacionClienteBonificado")
    RespuestaVo validarClienteBonifiado(String pMovil);
}

我的实体

import javax.persistence.NamedStoredProcedureQueries;
import javax.persistence.NamedStoredProcedureQuery;
import javax.persistence.ParameterMode;
import javax.persistence.StoredProcedureParameter;
import javax.persistence.Table;


@NamedStoredProcedureQueries({
    @NamedStoredProcedureQuery(
            name="SPValidationClienteBonus4G",
            procedureName="ValidacionClienteBonificado",
            parameters = {
                    @StoredProcedureParameter(mode=ParameterMode.IN, name="p_movil",type=String.class), 
                    @StoredProcedureParameter(mode=ParameterMode.OUT, name="code",type=String.class),
                    @StoredProcedureParameter(mode=ParameterMode.OUT, name="result",type=String.class),
            })

})

@Entity
@Table
public class DriverBonificados {

    @Id
    private int id;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getMovil() {
        return movil;
    }
    public void setMovil(String movil) {
        this.movil = movil;
    }
    public String getContador() {
        return contador;
    }
    public void setContador(String contador) {
        this.contador = contador;
    }
    public Date getFecha_driver() {
        return fecha_driver;
    }
    public void setFecha_driver(Date fecha_driver) {
        this.fecha_driver = fecha_driver;
    }
    public Date getFecha_alta() {
        return fecha_alta;
    }
    public void setFecha_alta(Date fecha_alta) {
        this.fecha_alta = fecha_alta;
    }
    public Date getFecha_fin() {
        return fecha_fin;
    }
    public void setFecha_fin(Date fecha_fin) {
        this.fecha_fin = fecha_fin;
    }
    public Date getCodigo_transaccion() {
        return codigo_transaccion;
    }
    public void setCodigo_transaccion(Date codigo_transaccion) {
        this.codigo_transaccion = codigo_transaccion;
    }
    private String movil;
    private String contador;
    private Date fecha_driver;
    private Date fecha_alta;
    private Date fecha_fin;
    private Date codigo_transaccion;

我的班级RespuestaVo

package com.app.validacion.entity;

public class RespuestaVo {

    private String code;
    private String result;

    public String getCode() {
        return code;
    }
    public void setCode(String code) {
        this.code = code;
    }
    public String getResult() {
        return result;
    }
    public void setResult(String result) {
        this.result = result;
    }

}

然后出现以下错误（移动参数必须以String形式接收，因为在数据库中它被视为Varchar）：

任何人都知道如何解决此问题？我是否需要通过存储过程进行咨询

更新

使用@Query并按如下所示修改代码：

package com.app.validacion.dao;

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.jpa.repository.query.Procedure;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;

import com.app.validacion.entity.DriverBonificados;
import com.app.validacion.entity.RespuestaVo;

public interface DriverBonificadosRepository extends CrudRepository<DriverBonificados, Integer> {

    @Query(nativeQuery = true,value = "call ValidacionClienteBonificado(:movil)")
    RespuestaVo validarClienteBonifiado(@Param("movil") String pMovil);
}

我收到以下错误：

org.springframework.core.convert.ConverterNotFoundException：否发现能够从类型转换的转换器 [org.springframework.data.jpa.repository.query.AbstractJpaQuery $ TupleConverter $ TupleBackedMap] 在以下位置键入[com.app.validacion.entity.RespuestaVo] org.springframework.core.convert.support.GenericConversionService.handleConverterNotFound（GenericConversionService.java:321）〜[spring-core-5.2.1.RELEASE.jar：5.2.1.RELEASE]在 org.springframework.core.convert.support.GenericConversionService.convert（GenericConversionService.java:194）〜[spring-core-5.2.1.RELEASE.jar：5.2.1.RELEASE]在 org.springframework.core.convert.support.GenericConversionService.convert（GenericConversionService.java:174）〜[spring-core-5.2.1.RELEASE.jar：5.2.1.RELEASE]在 org.springframework.data.repository.query.ResultProcessor $ ProjectingConverter.convert（ResultProcessor.java:297）〜[spring-data-commons-2.2.1.RELEASE.jar：2.2.1.RELEASE]在 org.springframework.data.repository.query.ResultProcessor $ ChainingConverter.lambda $ and $ 0（ResultProcessor.java:217）〜[spring-data-commons-2.2.1.RELEASE.jar：2.2.1.RELEASE]在 org.springframework.data.repository.query.ResultProcessor $ ChainingConverter.convert（ResultProcessor.java:228）〜[spring-data-commons-2.2.1.RELEASE.jar：2.2.1.RELEASE]在 org.springframework.data.repository.query.ResultProcessor.processResult（ResultProcessor.java:170）〜[spring-data-commons-2.2.1.RELEASE.jar：2.2.1.RELEASE]在 org.springframework.data.jpa.repository.query.AbstractJpaQuery.doExecute（AbstractJpaQuery.java:157）〜[spring-data-jpa-2.2.1.RELEASE.jar：2.2.1.RELEASE]

Answer 1

已解决

我设法使用@Query注释解决了自己的问题，并为要接收的响应构建了接口，在这种情况下，使用了2种方法（根据我将要接收的参数数量）这是我在Json中得到的答案，我将接口代码留在下面：

public interface RespuestaVo {

    String getCode();
    String getResult();

}

我建议使用@Query通过Spring Boot运行存储过程

Answer 2

尝试一下-

@GetMapping("/service/{movil}")
public RespuestaVo  ConsultarMovil(@PathVariable("movil") String movil) {
    return dao.validarClienteBonifiado(movil);

}

Spring Boot：类型不能为null；嵌套异常为java.lang.IllegalArgumentException：运行存储过程时类型不能为null
