spring和hibernate整合出的问题。。

Question

做一个练习，
我做了一个web项目，
然后问题是在一个测试类里面能存进去，但是要是从前台页面接受在一个servlet里调用save的话就报错。。我感觉是spring的问题，但是不知道怎么调。。报的异常

Answer 1

 Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]
Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V
你用了dwr了吗？
是不是包的版本不对

Answer 2

dwr还没用呢。。
包全是用myeclipse自动导进去的。。

Answer 3

这样写了一个测试能存进去，但是把这些弄到servlet里就不好使了。。public class Demo { /**
 * @param args
 */
public static void main(String[] args) {
// TODO Auto-generated method stub ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
UserDAO ud = (UserDAO) ac.getBean("userDAOimp");
ud.save(new Myuser(4,"4",4));


}}

Answer 4

Caused by: org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]
应该是这块的错误

Answer 5

WEB.xml配置
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:bean.xml</param-value>
</context-param>
<listener>
<listener-lass>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
此配置是由WEB实例化spring容器WebApplicationContext = WebApplicationContextUtils.getWebApplicationContext(this.getServlet().getServletContext());
通过此语句获取spring容器实例

Answer 6

classpath:bean.xml你的改成classpath:applicationContext.xml前提是你的XML配置在src根目录下

Answer 7

我试试先。。web.xml里就一个servlet的配置。。

Answer 8

WebApplicationContext   m没这个类怎么回事？？

Answer 9

java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V
少包啦

Answer 10

这个错误在网上查了一下怎么说是多包了啊。。是hibernate和spring的一个相同名字的包冲突了。

Answer 11

晕了晕了。。一直都是添加jar包，还从来没删除过jar包。。

Answer 12

有2个警告，log4j的，可以不理。
看主要的
Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)visit()没有找到这个匹配的方法，spring你是用自动aspected还是手动初始化？？检查一下beans.xml文件，我上次出问题也是xml里配置出错了。

Answer 13

WebApplicationContext applicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(this.getServlet().getServletContext());

Answer 14

用myeclipse添加的。。visit()这个方法是哪的？？

Answer 15

谢谢大家了。。问题搞定了。。就是spring里的asm包的问题。。
从myeclipse里删了他了。。
