没有为存储过程 get_empoyee_details 定义参数 emp_name

问题描述

我有点困惑，我正在尝试使用 Spring Boot JPA 调用存储过程。已经创建了一个简单的过程并使用 JPA 的 @NamedStoredProcedureQuery 注释调用该过程。

由于某些奇怪的原因我收到错误

没有为存储过程定义参数 emp_name get_empoyee_details。 在 com.microsoft.sqlserver.jdbc.sqlServerException.makeFromDriverError

我做错了什么，试图通过 stackoverflow 上的其他答案没有帮助

这是我的实体类

import lombok.Data;
import lombok.ToString;

@Entity
@Data
@ToString
@NamedStoredProcedureQuery(name = "get_empoyee_details",procedureName = "get_empoyee_details",resultClasses = {
        Employee.class },parameters = {
        @StoredProcedureParameter(name = "emp_name",mode = ParameterMode.IN,type = String.class) })
public class Employee {

    @Id
    @GeneratedValue
    private Long id;

    @Column(name = "designation")
    private String designation;

    @Column(name = "employee_name")
    private String employeeName;

    @Column(name = "employee_code")
    private String employeeCode;
}

我的控制器

@RestController
public class EmployeeController {

    @PersistenceContext
    private EntityManager entityManager;

    @SuppressWarnings("unchecked")
    @GetMapping("/employees")
    public ResponseEntity<List<Employee>> getEmp(@RequestParam(name = "name") String name) {
        List<Employee> employees = entityManager.createNamedStoredProcedureQuery("get_empoyee_details")
                .setParameter("emp_name",name).getResultList();
        return new ResponseEntity<>(employees,HttpStatus.OK);
    }
}

先谢谢你

堆栈跟踪

Error preparing registered callable parameter] with root cause

com.microsoft.sqlserver.jdbc.sqlServerException: Parameter emp_name was not defined for stored procedure get_empoyee_details.
    at com.microsoft.sqlserver.jdbc.sqlServerException.makeFromDriverError(sqlServerException.java:234) ~[mssql-jdbc-8.2.2.jre8.jar:na]

我的sql server存储过程

CREATE PROCEDURE get_empoyee_details @name nvarchar(30)
AS
SELECT * 
FROM employee
WHERE employee_name = @name
GO

解决方法

参数名称错误，如异常所述。

com.microsoft.sqlserver.jdbc.SQLServerException: 
    Parameter emp_name was not defined forstored procedure get_empoyee_details.

将其更改为名称：

@NamedStoredProcedureQuery(name = "get_empoyee_details",procedureName = "get_empoyee_details",resultClasses = { Employee.class },parameters = {
                              @StoredProcedureParameter(name = "name",// this was wrong
                                                        mode = ParameterMode.IN,type = String.class) })
public class Employee {
