我是Spring的新手用hibernate。我试图完成一个包含bellow文件的简单应用程序。 1.Employee.java
private int id;
private String name;
private float salary;
//and setter and getter
2.Employee.hbm.xml（包含所有映射详细信息）
3.EmployeeDao.java
public class EmployeeDao {
HibernateTemplate template;
public void setTemplate(HibernateTemplate template) {
this.template = template;
}
//method to save employee
public void saveEmployee(Employee e){
template.save(e);
}
//method to update employee
public void updateEmployee(Employee e){
template.update(e);
}
//method to delete employee
public void deleteEmployee(Employee e){
template.delete(e);
}
//method to return one employee of given id
public Employee getById(int id){
Employee e=(Employee)template.get(Employee.class,id);
return e;
}
//method to return all employees
public List<Employee> getEmployees(){
List<Employee> list=new ArrayList<Employee>();
list=template.loadAll(Employee.class);
return list;
}
}
4.applicationContext.xml如下所示：
<?xml version="1.0" encoding="UTF-8"?>

5.Test.java如下：
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
public class Test {
public static void main(String[] args) {
Resource r=new ClassPathResource("applicationContext.xml");
BeanFactory factory=new XmlBeanFactory(r);
EmployeeDao dao=(EmployeeDao)factory.getBean("d");
Employee e=new Employee();
e.setId(114);
e.setName("arun");
e.setSalary(50000);
dao.saveEmployee(e);
}
}
我在构建路径中添加了bellow jar文件。

我还尝试添加三个jar
cglib-2.2.2.jar
log4j-1.2.15.jar
slf4j-log4j12-1.5.6.jar
得到了相同的结果。
请帮我解决这个问题
答案 0 :(得分：0)
logback-classic-0.9.6.jar ContextInitializer.java不支持以下构造函数，这就是您遇到此问题的原因。
缺少构造函数
public ContextInitializer(LoggerContext loggerContext) {
this.loggerContext = loggerContext;
}
尝试升级到logback-classic-1.0.0.jar版本。
同时切换到slf4j-log4j12-1.0.1.jar。
