java

package sibintergartionp;

public class emplyeer {

    private int emp_id;  
    private String name;  
    private String address;
    private String desig;
    emplyeer empr=new emplyeer();
    public void setemp_id(int i) {
        // TODO Auto-generated method stub
        emp_id=i;
    }
    public void setname(String string) {
        // TODO Auto-generated method stub
        name=string;
    }
    public void setaddress(String string) {
        // TODO Auto-generated method stub
        address=string;
    }
    public void setdesig(String string) {
        // TODO Auto-generated method stub
        desig=string;
    }

错误：

org.apache.commons.dbcp.SQLNestedException:无法加载JDBC驱动程序 类'com.mysql.jdbc.driver'

原因：java.lang.ClassNotFoundException:com.mysql.jdbc.driver

线程“main”中出现异常 org.springframework.beans.factory.BeanCreationException:错误 正在创建在类路径资源中定义了名称为“d”的bean [context.xml]：无法解析对bean“template”的引用，而 设置bean属性“template”；嵌套异常是 org.springframework.beans.factory.BeanCreationException:错误 创建在类路径资源中定义了名为“template”的bean [context.xml]：无法解析对bean“mysessionFactory”的引用 设置bean属性“sessionFactory”时；嵌套异常是 org.springframework.beans.factory.BeanCreationException:错误 创建在类路径中定义了名为“mysessionFactory”的bean resource[context.xml]：调用init方法失败；嵌套 异常为org.hibernate.PropertyNotFoundException:找不到 SibiIntergartionP.Employeer类中emp_id的getter

您在此处输入了错误的驱动程序名称：

应该是

原因：org.springframework.beans.factory.BeanCreationException:创建类路径资源[context.xml]中定义的名为“template”的bean时出错：设置bean属性“sessionFactory”时无法解析对bean“mysessionFactory”的引用；嵌套异常为org.springframework.beans.factory.BeanCreationException:创建在类路径资源[context.xml]中定义的名为“mysessionFactory”的bean时出错：调用init方法失败；嵌套异常为org.hibernate.PropertyNotFoundException:未能在类sibintergartionp.emplyer中找到emp_id的getter，原因：org.springframework.beans.factory.BeanCreationException:创建名为“mysessionFactory”的bean时出错，该bean在类路径资源[context.xml]中定义：调用init方法失败；嵌套异常是org.hibernate.PropertyNotFoundException:在类sibiIntergartionP.Employer中找不到emp_id的getter，因为您没有getter？恐怕我不明白您在这里问什么。错误信息非常清楚；它试图调用您尚未编写的方法。为什么不直接编写它所寻找的getter呢？遵循基本的Java命名约定，它独立于Hibernate。
