框架整合错误

Question

我的applicationContext.xml文件是：
<?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-2.0.xsd">
<bean id="mydatasource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName"
value="oracle.jdbc.driver.OracleDriver">
</property>
<property name="url"
value="jdbc:oracle:thin:@127.0.0.1:1521:orcl">
</property>
<property name="username" value="scott"></property>
<property name="password" value="tiger"></property>
</bean>
<bean id="myfactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="mydatasource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.Oracle9Dialect
</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>com/sun/demo/UUser.hbm.xml</value></list>
</property></bean>
<bean id="testa" class="com.sun.demo.TestA">
<property name="se">
<ref bean="myfactory"/>
</property>
</bean>
</beans>
测试类TestA为：
import java.util.List;import org.hibernate.SessionFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.orm.hibernate3.HibernateTemplate;public class TestA {
SessionFactory se;
public SessionFactory getSe() {
return se;
} public void setSe(SessionFactory se) {
this.se = se;
} public void test(){


HibernateTemplate te=new HibernateTemplate(this.getSe());

List list=te.find("select u from u_user u");

System.out.println(list.size());


} /**
 * @param args
 */
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext at=new ClassPathXmlApplicationContext("applicationContext.xml");
TestA t=(TestA) at.getBean("testa");
t.test(); }}
报的错误是：

log4j:WARN Please initialize the log4j system properly.

Answer 1

<bean id="myfactory"改成sessionFactory

Answer 2

首先第一点 你先看看这个地方 ：<bean id="mydatasource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName"
value="oracle.jdbc.driver.OracleDriver">
</property>
<property name="url"
value="jdbc:oracle:thin:@127.0.0.1:1521:orcl">
</property>
<property name="username" value="scott"></property>
<property name="password" value="tiger"></property>
</bean>
也就是你的 dbcp  有没有加入包。。第二：你看看。。public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext at=new ClassPathXmlApplicationContext("applicationContext.xml");
TestA t=(TestA) at.getBean("testa");
t.test();}}
ClassPathXmlApplicationContext("applicationContext.xml");我估计是这个地方出的错。

Answer 3

Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)Vasm.jar包有没有？有没有报错信息中的方法？如果有的话，是不是jar包有冲突了？

Answer 4

一：
    sessionFactory的名字不能改成"mysessionFactory"
二：如果你有asm.jar，那么就是spring的asm-2.3.3(版本不同后面的数字也不同)跟它冲突了，把asm-2.3.3删掉就行了
