本人為初學者,以下是本菜鳥在實際運用時的記錄,大神可以跳過,當然也歡迎指點一二
<s:iterator var="word" value="#wordList>//其中wordList是與Action中context.put("wordList", wordList);裡的list集合相對應的,list裝的是資料庫東西,word只是個變數名    <s:property value="#word.details"/>//用<s:property取出wordList元素中的details屬性,  即資料庫中的details欄位                      </s:iterator>
private String time;
private Stringdetails;
public String getTime() {
  return time;
}
public void setTime(String time) {
  this.time = time;
}
public String getDetails() {
  return details;
}
public void setDetails(String details) {
  this.details = details;
}
 
public String showWordList()throws Exception{
  ActionContext context=ActionContext.getContext();
  List<Word> wordList=WordDao.getWordList();//List集合接收的是從Dao層傳來的資料庫內容
  context.put("wordList", wordList);
  return "word";
}
public static List<Word> getWordList()    {        Session session=HibernateSessionFactory.getSession();        try {                        Criteria criteria=session.createCriteria(Word.class);                        List<Word> word=criteria.list();//擷取資料庫裡的表裝到List集合中                        session.close();            return word;//返回list集合        } catch (Exception e) {            e.printStackTrace();        }        return null;    }
public class Word implements java.io.Serializable{    private static final long serialVersionUID = 1L;        private Integer id;        private String time;        private String details;        public Word() {    }    //重載構造方法    public Word(String time, String details) {        this.time = time;        this.details = details;    }...下面省略各個成員的set,get方法}
現在是hbm.xml,與hibernate.cfg.xml相關檔案的配置
//以下是hbm.xml<hibernate-mapping>    <!-- 映射資料庫的word表 -->    <class name="com.model.Word" table="word" catalog="se">        <!-- 映射id欄位 -->        <id name="id" type="java.lang.Integer">            <column name="id" />            <generator class="identity" />        </id>        <!-- 映射name欄位 -->        <property name="time" type="java.lang.String">            <column name="time" length="30" not-null="true" />        </property>        <!-- 映射pwd欄位 -->        <property name="details" type="java.lang.String">            <column name="details" length="2000" not-null="true" />        </property>    </class></hibernate-mapping>//以下是cfg.xml<hibernate-configuration><session-factory>    <property name="dialect">        org.hibernate.dialect.MySQLDialect    </property>    <!-- 連結地址 -->    <property name="connection.url">        jdbc:mysql://localhost:3306/se?useUnicode=true&characterEncoding=UTF-8    </property>    <!-- 資料庫user -->    <property name="connection.username">root</property>    <!-- 資料庫user密碼 -->    <property name="connection.password">root</property>    <!-- 串連driver -->    <property name="connection.driver_class">        com.mysql.jdbc.Driver    </property>    <property name="myeclipse.connection.profile">        com.mysql.jdbc.Driver    </property>    <property name="show_sql">true</property>    <property name="format_sql">true</property>    <!-- 對應檔 -->    <mapping resource="com/model/Word.hbm.xml" /></session-factory></hibernate-configuration>
<action name="wordpage" class="com.action.WordAction">            <result name="word">/user/word.jsp</result></action>
