java - Spring 无法加载 JDBC 驱动程序类错误

Question

在 spring jdbc javapoint 中执行 spring jdbc 示例时出现以下错误,

 Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ds' defined in class path resource [sjdbc1.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are: PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [oracle.jdbc.driver.OracleDriver]

Employee.java 我修改如下，其余的都是我从 javapoint 链接获取的，

1.Employee.java
package com.pro.sjdbc1;

public class Employee {
    private int id;
    private String name;
    private float salary;
    // no-arg and parameterized constructors
    // getters and setters
    Employee(int id,String name,float salary){
        id=this.id;
        name=this.name;
        salary=this.salary;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public float getSalary() {
        return salary;
    }
    public void setSalary(float salary) {
        this.salary = salary;
    }

}

Answer 1

您的类路径中没有 Oracle JDBC 驱动程序。您需要在 POM 文件中添加依赖项。

例如

<dependency>
 <groupId>com.oracle.jdbc</groupId>
 <artifactId>ojdbc7</artifactId>
 <version>x.xx</version>
</dependency>

请注意，这是一个示例。您将需要添加正确的驱动程序版本。 您可能还需要添加适当的 Oracle Maven 存储库 (https://maven.oracle.com)。 AFAIK Oracle JDBC 驱动程序不在标准 Maven 中央存储库中。
