八、hibernate面对几个错误的解决关键19
一
Stringhql="fromStationInfoawherea.stationCodelike'%"+stCode+"%'";
注意:
hql中StationInfo不是对应数据库中的表,而是对应值对象即:
hibernate的映射类文件,org.bean.StationInfo类
二SSH架构易出现的问题之Errorcreatingbeanwithname'*'definedinfile[*.xml]
org.apache.jasper.JasperException:
Errorcreatingbeanwithname'indexall'definedinfile[E:
\eclipse\Tomcat5.5\webapps\fc\WEB-INF\beans.xml]:

nestedexceptionisorg.springframework.beans.NotWritablePropertyException:
Invalidproperty'newsdao'ofbeanclass[org.fc.classes.indexall]:
Beanproperty'newsdao'isnotwritableorhasaninvalidsettermethod:
Doestheparametertypeofthesettermatchthereturntypeofthegetter?
这是一个很头痛的问题,基本解决方法有以下两种:
1,如上面提示在定义的ACTION方法里没写GET,SET方法或者是方法写的不规范
解决方法:
按如下编写看看能否解决.
Beasn.xml文件部分//此文件是SPRING的配置文件
//注册indexall这个ACTION
//注册newsdao
//最后必须在userDAOProxy中注册
********************************************* ********************************************* Indexall这个ACTION文件部分必须定义newsdao的GET,SET方法如下 privateNewsdaonewsdao; publicNewsdaogetnewsdao(){ returnnewsdao; } publicvoidsetnewsdao(Newsdaonewsdao){ this.newsdao=newsdao; } 请大家注意下划线的变量,相同颜色的名字必须一致,不可有大小写错误! 2.TOMCAT版本的问题.本人一次用TOMCAT5.0编写,出现了上面的问题,结果是怎么都解决不了,后来换成了TOMCAT5.5.就一点问题都没有了,所以第一种办法解决不了的请用此法看看,换个TOMCAT版本也许能解决问题,不过只对用5.0编写出问题有效哦. 三 1. org.hibernate.id.IdentifierGenerationException: idsforthisclassmustbemanuallyassignedbeforecallingsave(): 原因: 解决方法: 2. java.lang.IllegalArgumentException: idtoloadisrequiredforloading 方案: Usersuser=(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: couldnotexecutequery;nestedexceptionisorg.hibernate.exception.SQLGrammarException: couldnotexecutequery 方案: sql语句有错误 4. 严重: ErrorstartingstaticResources java.lang.IllegalArgumentException: DocumentbaseD: \ProgramFiles\ApacheSoftwareFoundation\Tomcat5.0\webapps\tomcat-docsdoesnotexistorisnotareadabledirectory 严重: ErrorinresourceStart() 2007-6-623: 32: 25org.apache.catalina.core.StandardContextstart 严重: ErrorgetConfigured 2007-6-623: 32: 25org.apache.catalina.core.StandardContextstart 严重: Contextstartupfailedduetopreviouserrors 2007-6-623: 32: 25org.apache.catalina.core.StandardContextstart 严重: Exceptionduringcleanupafterstartfailed LifecycleException: ContainerStandardContext[/tomcat-docs]hasnotbeenstarted 5.jsf+spring+hibernate 严重: Exceptionsendingcontextinitializedeventtolistenerinstanceofclassorg.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanCreationException: Errorcreatingbeanwithname'dataSource'definedinServletContextresource[/WEB-INF/applicationContext.xml]: Instantiationofbeanfailed;nestedexceptionisjava.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool Causedby: java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool 严重: ErrorlistenerStart 2007-6-810: 31: 55org.apache.catalina.core.StandardContextstart 严重: Context[/shj01]startupfailedduetopreviouserrors 2007-6-810: 31: 55org.apache.catalina.core.ApplicationContextlog 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 6. 严重: Exceptionsendingcontextinitializedeventtolistenerinstanceofclasscom.sun.faces.config.ConfigureListener javax.faces.FacesException: Can'tparseconfigurationfile: 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.springMVC+hibernate 严重: StandardWrapper.Throwable org.springframework.beans.factory.BeanCreationException: Errorcreatingbeanwithname'sessionFactory'definedinServletContextresource[/WEB-INF/applicationContext.xml]: Invocationofinitmethodfailed;nestedexceptionisjava.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V Causedby: 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.springMVC+hibernate Exceptioninthread"main"org.springframework.dao.InvalidDataAccessResourceUsageException: CouldnotexecuteJDBCbatchupdate;nestedexceptionisorg.hibernate.exception.SQLGrammarException: CouldnotexecuteJDBCbatchupdate Causedby: org.hibernate.exception.SQLGrammarException: CouldnotexecuteJDBCbatchupdate 9. org.springframework.beans.factory.CannotLoadBeanClassException: Errorloadingclass[org.springframework.transaction.interceptor.TransactionProxyFactoryBean]forbeanwithname'userService'definedinServletContextresource[/WEB-INF/applicationContext.xml]: problemwithclassfileordependentclass;nestedexceptionisjava.lang.NoClassDefFoundError: org/springframework/aop/framework/AbstractSingletonProxyFactoryBean Causedby: java.lang.NoClassDefFoundError: org/springframework/aop/framework/AbstractSingletonProxyFactoryBean 方案: 没加spring2.0aoplibraries 10. org.apache.jasper.JasperException: UnabletocompileclassforJSP: 方案: jsp网页中的java代码有问题 11.
