org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save():
原因：
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 is org.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 class org.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 is java.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.jar commons-dbcp.jar commons-pool.jar加载到工程去
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' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.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.

Caused by: 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'?
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 '' is defined
