1.  
 org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save():  
原因：元素配置不正确，元素缺少其子元素的配置。解决方法：元素映射了相应数据库表的主键字段，对其子元素,其中class的取值可以为increment、identity、sequence、hilo、native......等，一般取其值为native 。  
2.  
java.lang.IllegalArgumentException: id to load is required for loading  
方案:Users user=(Users)this.getHibernateTemplate().get(Users.class, id);如果以用户名为参数不能用此方法  
3.  
 org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute query; nested exception isorg.hibernate.exception.SQLGrammarException: could not execute query  
方案：sql语句有错误  
4.  
严重: Error starting static Resources  
java.lang.IllegalArgumentException: Document base D:/Program Files/Apache Software Foundation/Tomcat 5.0/webapps/tomcat-docs does not exist or is not a readable directory  
严重: Error in resourceStart()  
2007-6-6 23:32:25 org.apache.catalina.core.StandardContext start  
严重: Error getConfigured  
2007-6-6 23:32:25 org.apache.catalina.core.StandardContext start  
严重: Context startup failed due to previous errors  
2007-6-6 23:32:25 org.apache.catalina.core.StandardContext start  
严重: Exception during cleanup after start failed  
LifecycleException:  Container StandardContext\[/tomcat-docs\] has not been started  
5.jsf+spring+hibernate  
严重: Exception sending context initialized event to listener instance of classorg.springframework.web.context.ContextLoaderListener  
 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in ServletContext resource \[/WEB-INF/applicationContext.xml\]: Instantiation of bean failed; nested exception isjava.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool  
Caused by: java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool  
严重: Error listenerStart  
2007-6-8 10:31:55 org.apache.catalina.core.StandardContext start  
严重: Context \[/shj01\] startup failed due to previous errors  
2007-6-8 10:31:55 org.apache.catalina.core.ApplicationContext log

方案：spring-framework-2.0.5/lib/jakarta-commons下的commons-collections.jarcommons-dbcp.jarcommons-pool.jar加载到工程去

我的解决办法是，导入ssh整合包后(三大框架所需包),配置web.xml的监听器，需要把项目从Tomact中移除再重新部署一次，问题解决了。

6.  
严重: Exception sending context initialized event to listener instance of class com.sun.faces.config.ConfigureListener  
javax.faces.FacesException: Can't parse configuration file:jar:file:/E:/工具/apache-tomcat-6.0.9/apache-tomcat-6.0.9/webapps/jsf02/WEB-INF/lib/jsf-impl.jar!/com/sun/faces/standard-html-renderkit.xml  
方案：把tomcat的安装文件换了位置就没事了  
7.spring MVC+hibernate  
严重: StandardWrapper.Throwable  
 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' definedin ServletContext resource \[/WEB-INF/applicationContext.xml\]: Invocation of init method failed; nested exception isjava.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;\[Ljava/lang/String;Ljava/lang/String;)V  
Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;\[Ljava/lang/String;Ljava/lang/String;)V  
方案：  
在使用Spring的AOP编程时，会用到这几个lib：  
asm-2.2.2.jar  
asm-commons-2.2.2.jar  
asm-util-2.2.2.jar  
Hibernate使用如果lib：  
asm.jar  
asm-attrs.jar  
其中asm-2.2.2.jar与asm.jar存在类上的冲突！！！  
使用其中之一或两者都使用，可能会出现如下错误：  
java.lang.NoClassDefFoundError: org/objectweb/asm/CodeVisitor  
java.lang.NoClassDefFoundError: org/objectweb/asm/commons/EmptyVisitor  
java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit。。。。。。  
解决办法是：  
1.去掉类路径上的关于Hibernate的3个lib  
asm.jar  
asm-attrs.jar  
cglib-2.1.3.jar  
2.加入Spring中的以下4个lib  
asm-2.2.2.jar  
asm-commons-2.2.2.jar  
asm-util-2.2.2.jar  
cglib-nodep-2.1\_3.jar  
8.spring MVC+hibernate  
 Exception in thread "main" org.springframework.dao.InvalidDataAccessResourceUsageException: Could not execute JDBC batch update; nested exception is org.hibernate.exception.SQLGrammarException: Could not execute JDBC batch update  
Caused by: org.hibernate.exception.SQLGrammarException: Could not execute JDBC batch update  
9.  
 org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class \[org.springframework.transaction.interceptor.TransactionProxyFactoryBean\] for bean with name 'userService'defined in ServletContext resource \[/WEB-INF/applicationContext.xml\]: problem with class file or dependent class;nested exception is java.lang.NoClassDefFoundError:org/springframework/aop/framework/AbstractSingletonProxyFactoryBean  
Caused by: java.lang.NoClassDefFoundError:org/springframework/aop/framework/AbstractSingletonProxyFactoryBean  
方案：没加 spring 2.0 aop libraries  
10.  
 org.apache.jasper.JasperException: Unable to compile class for JSP:  
方案：jsp网页中的java代码有问题  
11.  
 Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'CompanyController' defined in class path resource \[com/company/test/company-config.xml\]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'methodNameResolver' of bean class \[com.company.action.CompanyController\]: Bean property 'methodNameResolver' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?  
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'methodNameResolver' ofbean class \[com.company.action.CompanyController\]: Bean property 'methodNameResolver' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?  
  
  
控制器没继承MultiActionController  
  
12.  
  
  
 Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'turDiffService' defined in class path resource \[com/expert/test/expert-config.xml\]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'turDifficultDao' of bean class \[com.expert.operation.impl.TurDiffSerImpl\]: Bean property 'turDifficultDao' is not writable or has an invalid setter method. Did you mean 'truDifficultDao'?  
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'turDifficultDao' of beanclass \[com.expert.operation.impl.TurDiffSerImpl\]: Bean property 'turDifficultDao' is not writable or has an invalid setter method. Did you mean 'truDifficultDao'?  
原因：  
在定义时TurDifficultDao turDifficultDao，把有个字母写错，后发现错误，改过来了，但没把get()set()方法中对应的改过来  
  
13.  
  
 Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'urlMapping' defined in class path resource \[com/expert/test/expert-config.xml\]: Initialization of bean failed;nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named '' isdefined  
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named '' is defined  
  
  
原因：  
在expert-config.xml中创建  
<</span>bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">  
  
  
  
  
  
  
  
</</span>bean>  
没有给赋值  
  
14.  
  
 org.springframework.orm.hibernate3.HibernateQueryException: Instruction is not mapped  
  
\[from Instruction\]; nested exception is org.hibernate.hql.ast.QuerySyntaxException:  
  
Instruction is not mapped \[from Instruction\]  
Caused by: org.hibernate.hql.ast.QuerySyntaxException: Instruction is not mapped \[from  
  
Instruction\]  
原因：在data-config.xml中没加入com/serializ/Instruction.hbm.xml  
15.  
  
java.sql.SQLException: Field 'userId' doesn't have a default value  
原因：把配置文件的主键改为 可以进行自定义主键值，因为我在设主键时没有设成自动增长的，要求填默认值是受了配置文件里的影响了。  
  
16.org.apache.jasper.JasperException: Unable to compile class for JSP  
  
原因：jsp页面中的java代码括号不对称！

17.Error creating bean with name 'sessionFactory '

网友回复:Error creating bean with name 'sessionFactory '  
网友回复: 'UserDAO ' 这个 java Bean 有问题，

导致 ： 严重: action: null  
再试试， 有可能是 没有符合javabean 的规则

网友回复:spring的配置文件有错误~~  
网友回复:UserDAO是自动生成的，spring配置肯定没问题啊  
网友回复:我遇到的问题跟你遇到的一模一样，我到现在也还没能解决出来，如果你解决了希望能告诉一下。非常感谢  
网友回复:RP  
网友回复:看错误信息，似乎是java bean里的setter方法不正确。建议检查一下。  
网友回复:Caused by: java.lang.NoClassDefFoundError:org/apache/commons/pool/impl/GenericObjectPool  
是一些包没有加载进去吧  
eclipse是数据字典的方式加载的,放到tomcat中要重新引用  
网友回复:我在上面写到跟你出的问题大概差不多，我现在我的问题已经解决掉了，我在service类修改了一下，我的service是不是用工具生成的，我的错误是service继承了hibernateDaoSupport类，粗

心造成的  
网友回复:我也遇到这个错误了，不过在网上终于找到了答案，你这个是一个包没有导入进去，

"close "> 除了需要commons-dbcp-1.2-1.jar之外还需要commons-pool.jar这个包，把后面这个commons-pool.jar包导入进去就应该行了，我的是这样解决的

网友回复:commons-pool.jar:  
[http://www.apache.org/dist/commons/pool/commons-pool-current.zip][http_www.apache.org_dist_commons_pool_commons-pool-current.zip]  
commons-dbcp-1.2.1.jar:
