1.should   be   mapped   with   insert="false"   update="false"

解决方案:

 1).两个属性不能对应一行
 2).在建立多对一关系映射时,出问题,具体如下:

 /**
  * @hibernate.many-to-one column="personal_id"
  *                        class="com.cmp.yiwu.psn.self.model.Personaldossier"
  *                        outer-join="auto" cascade="none"
  */
 而当前类中也有了personal_id属性,故会报错.应将当前为中属性去掉即可. 
 

2.ERROR - BatchingBatcher.doExecuteBatch(61) | Exception executing batch:
org.hibernate.StaleStateException: Batch update returned unexpected row count from update: 0 actual row count: 0 expected: 1

ERROR - AbstractFlushingEventListener.performExecutions(300) | Could not synchronize database state with session

解决方案:???没有取得主表对象

3.cascade="none" cascade="all" 是否级联更新

  set lazy="true" 是否延迟加载.

4.分页不成功_点击下一页无响应. ***************解决

解决方案:*.jsp页面不能将分页自定义标签嵌入到当前页面的form中.

5.one-to-one 的几种形式:

第一种:不指定字段

主类:     /**
    * @hibernate.one-to-one class = "com.cmp.yiwu.psn.family.model.FamilyHealthCare"
    *                       outer-join = "true" cascade="all"
    * @return Returns
    */
子类:   /**
    * @hibernate.one-to-one  class="com.cmp.yiwu.psn.family.model.FamilyInformation"
    *                        constrained="true"
    *                        cascade="none"  outer-join="auto" 
    */

第二种:在多对一时,指定uinque="true"属性

6.门诊号码的产生,格式化问题? 解决

7.ERROR - StandardWrapperValve.invoke(250) | Servlet.service() for servlet action threw exception
java.lang.ClassCastException:

7.待解决问题:
     (1).时间查询between ... and ...?    ***************解决
     (2).时间与字符串间的转换?  ***************解决
     (3).整型值0001，格式化问题?    ***************解决

8.在普通的类中取得spring配置文件中定义的bean???? 没解决

// 
// //static ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext("applicationContext.xml");
// ApplicationContext appContext=new ClassPathXmlApplicationContext("applicationContext.xml");
// //ApplicationContext appContext = new FileSystemXmlApplicationContext("csm/WebRoot/WEB-INF/applicationContext.xml");
// BeanFactory factory = (BeanFactory) appContext;
// //public static Get_GuaHao_Number REPTRBUSINESS =(Get_GuaHao_Number)appContext.getBean("REPTRBUSINESS");
//

ERROR - RequestProcessor.processMapping(664) | Invalid path /csm/ajax/qkzl/jiuzhen/right was requested
2007-10-5 9:19:17 org.apache.tomcat.util.http.Parameters processParameters
警告: Parameters: Invalid chunk ignored.

10.两表连接查询返回集合不得存放于session中转向.

解决方案:

将对象拷贝 ObjectCopyProperty.notNullPropertyCopy(person, gua.getPersonaldossier());

11.数据分页后，超链接不保持????  -----待解决

12.保存数据时:
INFO - NullableType.nullSafeSet(87) | could not bind value '0' to parameter: 3; java.lang.Integer
ERROR - StandardWrapperValve.invoke(250) | Servlet.service() for servlet action threw exception
java.lang.ClassCastException: java.lang.Integer

解决方案:

实体配置中age数据字段类型为int,而数据库配置为long,数据类型不统一,即使不添加测试数据也报加载错误!!!

13.就诊查询与查询分页时,点击下一页无响应或报错...

14.
ERROR - ApplicationDispatcher.invoke(723) | Servlet.service() for servlet jsp threw exception
java.lang.NoClassDefFoundError: net/sf/hibernate/HibernateException 

分页时:action中必须调用分页的方法,否则直接跳转到页面中会无法显示，以导致500的错误.

15.超连接传递javascript变量:

url:
aid.href="<!--equest.getContextPath(-->/ajax/zhuanZhen_chu_FindInfoByPersonId.do?personal_id="+url;

aid为....

16.保存数据后再根据ID查询一次数据....

new ActionForward("url.do?id=123");即:

return new ActionForward("/ajax/zhuanZhen_FindRuInfo.do?personal_id="+personal_id);
