我書面方式使用Spring和Hibernate使用以下豆定義XML文件簡單的應用程序:春java.lang.NoClassDefFoundError在CCTOR
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="hibernateConfiguration" class="pl.wicia.projector.database.DBConfiguration" scope="prototype">
<constructor-arg name="path" value="pl/wicia/projector/database/cfg.xml"/>
</bean>
<bean id="sessionFactory" class="pl.wicia.projector.database.HibernateSessionFactory" scope="prototype">
<constructor-arg name="dbConfig" ref="hibernateConfiguration"/>
</bean>
</beans>
現在,我想用注射用構造器參數傳遞給創建數據庫配置包裝:
package pl.wicia.projector.database;
import org.hibernate.cfg.Configuration;
public class DBConfiguration {
private Configuration configuration;
public DBConfiguration(String path){
this.configuration = new Configuration(); <--- this throws Exsception
this.configuration.configure(path);
}
public Configuration getConfiguration() {
return configuration;
}
}
而此行產生以下異常:

這是我如何創建我的豆類:
ApplicationContext context = new ClassPathXmlApplicationContext("pl/wicia/projector/spring/db_beans.xml");
DBConfiguration config = (DBConfiguration)context.getBean("hibernateConfiguration");
任何想法發生了什麼? :)
對於它的價值,100%的配置可以簡單地通過使用Spring Boot來消除。 – chrylis
