2、ere a.stationCode like %+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Error creating bean with name * defined in file *.xmlorg.apache.jasper.JasperException: Error creating bean with name indexall defined in file E:eclipseTomcat 5.5webappsfcWEB

4、h the return type of the getter? 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 /newsdao为此ACTION调用的DAO文件 /注册newsdao /最后必须在userDAOProxy中注册bean id=userDAOProxy * * Indexall这个ACTION文件部分必须定义newsdao的GET，SET方法如下 private

5、Newsdao newsdao; public Newsdao getnewsdao() return newsdao; public void setnewsdao(Newsdao newsdao) 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.hibe

6、rnate.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 loadi

7、ng 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 star

16、g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/EmptyVisi

17、tor 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.springfr
