Auto complete with Jquery

1. config servlet in web.xml
<servlet>
    <servlet-name>addressData</servlet-name>
    <servlet-class>com.xxx.webapp.AddressDataAutoCompleteServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    </servlet>

2. set autocomplete in JSP
$().ready(function() {

$("#addressLine1").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressLine");
$("#addressLine2").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressLine2");
$("#addressLine3").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressLine3");
$("#addressCity").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressCity");
$("#addressPostCode").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressPostCode");
$("#firstFocusObj").focus();
});

<html:text name="" tabindex="9" style="color: grey;" onclick="clearAddressValue(this)" styleId="addressLine1" value='<%=request.getAttribute("postalAddress1") == null ? defalutAddressValue : (String)request.getAttribute("postalAddress1")%>' property="TLContactDetailForm.postalAddress1" size="50" maxlength="50" styleClass="inputText2"></html:text>

SSH2中，直接獲取SEQUENCE的NEXTVAL ，使用OracleSequenceMaxValueIncrementer

SSH2中，直接獲取SEQUENCE的NEXTVAL

使用Spring的類 org.springframework.jdbc.support.incrementer.OracleSequenceMaxValueIncrementer

Spring配置文件：

1     <bean id="userDao" class="com.xx.dao.impl.UserDAOImpl">
2         <property name="sessionFactory" ref="sessionFactory" />
3         <property name="seqGenerator" ref="seqDispGenerator"></property>
5     </bean>
6
7     <bean id="seqDispGenerator" class="org.springframework.jdbc.support.incrementer.OracleSequenceMaxValueIncrementer">
8         <property name="dataSource" ref="dataSource"></property>
9         <property name="incrementerName" ><value>SEQ_DISP_ID</value></property>
10     </bean>

UserDAOImpl.java中引用：

private OracleSequenceMaxValueIncrementer seqGenerator;



    /**
     * @return the seqGenerator
     */
    public OracleSequenceMaxValueIncrementer getSeqGenerator() {
        return seqGenerator;
    }

    /**
     * @param seqGenerator the seqGenerator to set
     */
    public void setSeqGenerator(OracleSequenceMaxValueIncrementer seqGenerator) {
        this.seqGenerator = seqGenerator;
    }

UserDAOImpl.java中調用：

1 System.out.println("---------------------- this.seqGenerator().nextIntValue="+this.seqGenerator.nextIntValue());
