struts2.1.6+hibernate3.3+spring3.0遇到的问题

首先进行单元测试：出现问题

Java代码

package com.zzc.junit; import java.util.List; import javax.annotation.Resource; import org.junit.Test; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; import org.springframework.transaction.annotation.Transactional; import com.zzc.dao.SqlServerDao; @ContextConfiguration("classpath:applicationContext.xml") public class Test1 extends AbstractJUnit4SpringContextTests { SqlServerDao sqlServerDAO; @Test public void query() { List<String> list = sqlServerDAO.query(); for(String s : list) { System.out.println(s); } } public SqlServerDao getSqlServerDAO() { return sqlServerDAO; } @Resource(name="sqlServerDao") public void setSqlServerDAO(SqlServerDao sqlServerDAO) { this.sqlServerDAO = sqlServerDAO; } }

package com.zzc.junit;

import java.util.List;

import javax.annotation.Resource;

import org.junit.Test;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.transaction.annotation.Transactional;

import com.zzc.dao.SqlServerDao;

@ContextConfiguration("classpath:applicationContext.xml")
public class Test1 extends AbstractJUnit4SpringContextTests {

SqlServerDao sqlServerDAO;

@Test
public void query() {
List<String> list = sqlServerDAO.query();
for(String s : list) {
System.out.println(s);
}
}

public SqlServerDao getSqlServerDAO() {
return sqlServerDAO;
}

@Resource(name="sqlServerDao")
public void setSqlServerDAO(SqlServerDao sqlServerDAO) {
this.sqlServerDAO = sqlServerDAO;
}

}

问题1：

Caused by: java.lang.NoClassDefFoundError: org/junit/runners/BlockJUnit4ClassRunner

上网查看了下，原来是junit的jar包版本问题，spring2.5.6配搭junit4.4是没有问题的，但是spring3.0配搭junit4.4，使用了

@ContextConfiguration等spring3.0新的annotation就会有问题，将junit4.4改为junit4.82版本，问题解决。

问题2：

org/aopalliance/intercept/MethodInterceptor

Spring3.0 运行问题

报的错误是：java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor

上网查了下，这可能是spring3.0特有的问题，2.5就没有！出错的原因是少了个包，解决的方案是去

http://sourceforge.net/projects/aopalliance/files/下载aopalliance-alpha1.jar，加到路径里，就行了！

spring3.0比2.5需要好多额外的包，除了上面的aopalliance外，还可能会需要asm和cglib！

下载加入了aopalliance-alpha1.jar，进行测试，再次抛出异常:

问题3：

Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class

[org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator]: Constructor threw exception; nested

exception is java.lang.NoClassDefFoundError: org/aopalliance/aop/Advice

Caused by: java.lang.NoClassDefFoundError: org/aopalliance/aop/Advice

上网查看，发现又少了 com.springsource.org.aopalliance-1.0.0.jar 的jar包

到http://grepcode.com/snapshot/repository.springsource.com/org.aopalliance/com.springsource.org.aopalliance/1.0.0页面下载

com.springsource.org.aopalliance-1.0.0.jar

下载地址：

http://repository.springsource.com/ivy/bundles/external/org.aopalliance/com.springsource.org.aopalliance/1.0.0/com.springsour

ce.org.aopalliance-1.0.0.jar

问题4：

再次进行测试，又出现了新的问题：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlServerDao' defined in

file [E:\dormitory\Dormitory\WebRoot\WEB-INF\classes\com\zzc\dao\impl\SqlServerDaoImpl.class]:
Initialization of bean failed;

nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named

'org.springframework.transaction.interceptor.TransactionInterceptor#0' must be of type [org.aopalliance.aop.Advice], but was

actually of type [org.springframework.transaction.interceptor.TransactionInterceptor]

Caused by: org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named

'org.springframework.transaction.interceptor.TransactionInterceptor#0' must be of type [org.aopalliance.aop.Advice], but was

actually of type [org.springframework.transaction.interceptor.TransactionInterceptor]

解决方案：

将applicationContext.xml中的<tx:annotation-driven transaction-manager="transactionManager" />这一行注释掉

再运行，通过了。 但存在的问题是 事务不能工作了。

再解决：

TransactionInterceptor是 org.aopalliance.aop.Advice 的一个实现，可能是Jar包的冲突。

到jar包中去查看。

我的问题是： aopalliance-1.0.jar 和 aopalliance-alpha1.jar之间的冲突。

将aopalliance-alpha1.jar去掉，再运行就OK了。

问题5：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlServerDao' defined in

file [E:\dormitory\Dormitory\WebRoot\WEB-INF\classes\com\zzc\dao\impl\SqlServerDaoImpl.class]: BeanPostProcessor before

instantiation of bean failed; nested exception is
java.lang.NoClassDefFoundError: org/aspectj/lang/annotation/Aspect

Caused by: java.lang.NoClassDefFoundError: org/aspectj/lang/annotation/Aspect

加入aspectjrt.jar和aspectjweaver.jar，问题解决

问题6：

Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class

[com.mchange.v2.c3p0.ComboPooledDataSource] for bean with name 'sqlServerDataSource' defined in class path resource

[applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: com.mchange.v2.c3p0.ComboPooledDataSource

Caused by: java.lang.ClassNotFoundException: com.mchange.v2.c3p0.ComboPooledDataSource

一看知道，少了c3p0的jar，因为我使用了c3p0的数据源

Java代码

<bean id="mysqlDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

<property name="driverClass" value="org.gjt.mm.mysql.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/dormitory?

<property name="user" value="root"/>
<property name="password" value="123456"/>

</bean>

</bean>

加入c3p0-0.9.1.2.jar，问题解决
