出现上面错误可以产看一下Struts.xml插件那是否配错了
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property value="/WEB-INF/applicationContext.xml" property="
contextConfigLocation
"/>注意第一个字母是小写，若果大写就会出现上述情况了
</plug-in>
使用spring
ApplicationContext context = new FileSystemXmlApplicationContext("src/applicationContext.xml");
IDISK idisk = (IDISK)context.getBean("disk");//根据配置文件的内容实例化对象并返回
配置文件
scope="prototype"取消单态，延迟加载只针对单态的bean适用，非单态的bean本来就是“延迟加载”
<bean id="dbreader" class="reader.DBReader" scope="prototype">
<!-- 构造方法注入
<constructor-arg index="0" type="java.lang.String">
<value>sfk</value>
</constructor-arg>
<constructor-arg index="1" type="java.lang.String">
<value>sfk</value>
</constructor-arg>
-->
<property name="driverClassname">
<value>sun.jdbc.odbc.JdbcOdbcDriver</value><!-- 属性注入 -->
</property>
<property name="url">
<value>url</value>
</property>
<property name="username">
<value>username</value>
</property>
<property name="password">
<value>password</value>
</property>
</bean>
核心代码
Session session = util.HibernateSessionFactory.getSession();
School school = (School)session.get(School.class,
02
);
System.out.println(school.getSname());
System.out.println(school.getHeader().getHname());
school.getHeader().setHname("王强");
Transaction transaction = session.beginTransaction();
session.update(school);
session.delete(school);
transaction.commit();
util.HibernateSessionFactory.closeSession();
配置文件
<class name="po.School" table="school">
<id column="SID" name="sid">
<generator class="assigned"/>
</id>
<property column="SNAME" generated="never" lazy="false" name="sname"/>
<one-to-one cascade="all" class="po.Header" name="header"/>
</class>
<class name="po.Header" table="Header">
<id name="hid" column="HID">
<generator class="increment" />
</id>
<property name="sid" column="SID"/>
<property name="hname" column="HNAME"/>
</class>
hibernate 与数据库的耦合性较低。
在一对一关系中要注意找出谁是主动方，在上面的例子中School是主动方，在主动方里面添加被动方的属性，上述例子添加了Header属性，然后到配置文件中注册。使用的时<one-to-one、>
如果在使用ps 3D->从图层新建形状->...出现下边错误
1、DispatchAction
当一个action要处理两个操作时，如以下情况
<html:form
action="/buy.do?method=add"
method="post">
请您选择书本 : <html:text property="book"/><html:errors property="book"/><br/>
<html:submit value="添加到购物车"/>
</html:form>
<hr>
以下是您选的熟本<br>
<logic:present name="cart">
<logic:iterate id="book" name="cart">
<bean:write name="book"/><html:link
action="/buy.do?method=delete"
paramId="BOOK" paramName="book">删除</html:link><br>
</logic:iterate>
</logic:present>
我们都是用buy这个action来处理的，action继承了DispatchAction，为了让页面识别action中的add()方法和delete()方法，我们需要在struts.xml中配置<action parameter="method"></action>，这种方法耦合性高。需要页面识别action中的方法。
2、MappingDispatchAction
这种方法可以降低耦合性，指向多个结构不同的ActionForm，以上jsp可以如下
<html:form
action="/add.do"
method="post">
请您选择书本 : <html:text property="book"/><html:errors property="book"/><br/><html:submit value="添加到购物车"/>
</html:form>
<hr>
以下是您选的熟本<br>
<logic:present name="cart">
<logic:iterate id="book" name="cart">
<bean:write name="book"/><html:link
action="/delete.do"
paramId="BOOK" paramName="book">删除</html:link><br>
</logic:iterate>
</logic:present>
在struts.xml中设置如下<action path="/add"parameter="add"></action>
<action path="delete"parameter="delete"></action>
3、LookupDispatchAction
这种情况一般是同一个表单可以提交到多个不同的按钮，这种方法耦合性低，比较麻烦，需要用到资源文件。举例：jsp如下
<html:form action="/lr">
account : <html:text property="account"/><br/>
password : <html:text property="password"/><br/>
<html:submit
property="ope"
><bean:message key="info.tag.login"/></html:submit>
<html:submit
property="ope"
><bean:message key="info.tag.reg"/></html:submit>
</html:form>
我们在action中需要重写getKeyMethodMap()
protected Map getKeyMethodMap() {//用一个map保存资源文件和方法名的映射
// TODO Auto-generated method stub
Map map = new HashMap();
map.put("info.tag.login","
login
");
map.put("info.tag.reg","
reg
");
return map;
}
login 和 reg 用来选择方法。在struts.xml中需要作如下配置
<actionparameter="ope"></action>
