bug汇总
1、ssh项目整合，代码正确，仔细观察报错信息，缺少哪个jar包
2、在页面往action中传递对象，注意：
*页面中对象及属性与action中对象与属性一致
*action中需要接收的对象及属性设置set/get方法
*接收的对象必须有无参构造
3、eclipse打不开，
解决1：换工作空间，将原项目导入进去
解决2：可以删除工作空间下的lock文件和某个文件，百度有很多种
4、Unknown tag (s:token). 用struts标签前先引入struts标签
5、定义拦截器并引入，程序不重启二次访问出现：
No result defined for action org.superman.ssh.action.UserAction and result inputNo result defined for action org.superman.ssh.action.UserAction and result input
No result defined for action org.superman.ssh.action.UserAction and result input
解决办法1：为main action添加result input配置
<result name="input" type="dispatcher">
/WEB-INF/jsp/main.jsp
</result>
添加成功或失败返回原页面继续添加，出现相同token被拦截，添加失败
1、从添加成功页面跳转到，地址定义为自动跳转window.setTimeout("location.href='user/main.action'",3000);或手动跳转
6、Exception in thread "main" java.lang.NoClassDefFoundError: org/hibernate/QueryTimeoutException
Hibernate批量插入时，出现这个错误org.hibernate.QueryTimeoutException:
可能原因1：是表空间的容量不足，需要加大空间容量；那首先想到的是应该查询其容量，所以应该想办法查询其容量以及增大其容量
可能原因2：数据长度太长，超过了字段的长度限制，增加字段的长度限制
7、No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
解决办法：
在src下面新建file名为log4j.properties内容如下:
# Configure logging for testing: optionally with log file
log4j.rootLogger=WARN, stdout
# log4j.rootLogger=WARN, stdout, logfile
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.File=target/spring.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n
重新发布，OK,没有提示了。加入了这个配置文件后，再次运行程序上面的警告就会消失。尤其在进行Web 层开发的时候，只有加入了这个文件后才能看到Spring 后台完整的出错信息。在开发Spring 整合应用时，经常有人遇到出现404 错误但是却看不到任何出错信息的情况，这时你就需要检查一下这个文件是不是存在。
8、
Exception in thread "main" java.lang.NoClassDefFoundError: org/hibernate/QueryTimeoutException
将hibernate3的jar包换成hibernate4的jar包，hibernate3jar包中包含的是QueryException.class，QueryParameterException.class，没有QueryTimeoutException
9、
Exception in thread "main" 2017-01-23 10:31:12,653 WARN [org.springframework.context.support.ClassPathXmlApplicationContext] - Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'UserAction' defined in class path resource [config/spring/applicationContext-user.xml]: Cannot resolve reference to bean 'userService' while setting bean property 'userService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService' defined in class path resource [config/spring/applicationContext-service.xml]: Cannot resolve reference to bean 'userDao' while setting bean property 'userDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDao' defined in class path resource [config/spring/applicationContext-dao.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [config/spring/applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: [Lorg/hibernate/engine/FilterDefinition;
找不到 Caused by: java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool 就是Apache所提供的基本对象池。
解决办法：
到这里http://commons.apache.org/downloads/download_pool.cgi下载包，然后,把里面的commons-pool-x.jar复制到myEclipse的Referenced Libraries下.
10、org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'UserAction' defined in class path resource [config/spring/applicationContext-user.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.support.DefaultBeanFactoryPointcutAdvisor#0': Cannot resolve reference to bean 'pointCut' while setting bean property 'pointcut'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pointCut': Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException
缺少aspectjweaver.jar
11、Eclipse报错：
Description Resource Path Location Type
Target runtime com.genuitec.runtime.generic.jee70 is not defined. MyBatis01 Unknown Faceted Project Problem
解决办法：在工程目录下的settings，打开org.eclipse.wst.common.project.facet.core.xml文件，会发现<runtime name="com.genuitec.runtime.generic.jee60" />，把这句话去掉就OK了
12、telnet 127.0.0.1:3306 正在连接127.0.0.1:3306...无法打开到主机的连接。在端口 23:连接失败
解决办法：telnet 127.0.0.1 3306
13、spring4+hibernate4，出现异常Write operations are not allowed in read-only mode (FlushMode.MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.
解决方法：在hibernate操作前添加，getSessionFactory().getCurrentSession().setFlushMode(FlushMode.AUTO); 设置下FlushMode
