spring的portlet改进(二)支持CURD标注controller

spring的portlet改进(二)支持CURD标注controller

controller层标注应用的后台是manager层，这层只做了简单的MOCK，代码如下，
接口文件AddressManager.java
package com.sillycat.easyportlet.services;
import java.util.List;
import com.sillycat.easyportlet.model.Address;
public interface AddressManager {
public Address get(Integer id);
public List<Address> list();
public void delete(Integer id);
public void create(Address address);
public void update(Address address);
}
实现文件AddressManagerImpl.java：
package com.sillycat.easyportlet.services.impl;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import com.sillycat.easyportlet.model.Address;
import com.sillycat.easyportlet.services.AddressManager;
public class AddressManagerImpl implements AddressManager {
public Map<Integer, Address> map = new HashMap<Integer, Address>();
public Address get(Integer id) {
   Address a = null;
   if (map != null && !map.isEmpty()) {
    a = map.get(id);
   }
   return a;
}
public List<Address> list() {
   List<Address> list = null;
   if (map != null && !map.isEmpty()) {
    list = new ArrayList<Address>(map.size());
    Iterator<Integer> itkey = map.keySet().iterator();
    for (; itkey.hasNext();) {
     Integer id = itkey.next();
     list.add(map.get(id));
    }
   }
   return list;
}
public void create(Address address) {
   Date d = new Date();
   address.setId((new Long(d.getTime()).intValue()));
   map.put(address.getId(), address);
}
public void update(Address address) {
   if (map != null && !map.isEmpty()) {
    if (map.containsKey(address.getId())) {
     map.put(address.getId(), address);
    }
   }
}
public void delete(Integer id) {
   if (map != null && !map.isEmpty()) {
    if (map.containsKey(id)) {
     map.remove(id);
    }
   }
}
}
这些方法都没有什么特别，和平时的MANAGER一致。POJO
package com.sillycat.easyportlet.model;
import java.io.Serializable;
public class Address implements Serializable {
private static final long serialVersionUID = 5306372860419718840L;
private Integer id;
private String name;
private String address;
private String telphone;
private String mobile;
private String email;
...getter 和setter
}
页面撰写，调用不同的模式，实现编辑模式的CRUD，VIEW模式的LIST和VIEW
首先引入WEB-INF/portlets/easyportlet/taglibs.jsp
<%@ taglib prefix="c"       uri="http://java.sun.com/jstl/core_rt" %>
<%@ taglib prefix="portlet" uri="http://java.sun.com/portlet" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="form"    uri="http://www.springframework.org/tags/form" %>
新增页面addressAdd.jsp
<%@ include file="taglibs.jsp" %>
<h1>Add Address</h1>
<portlet:actionURL var="formAction" portletMode="edit">
    <portlet:param name="action" value="save"/>
</portlet:actionURL>                      
<form:form modelAttribute="address" method="post" action="${formAction}">
    <form:errors path="*" cssStyle="color:red"/>
    <form:hidden path="id" />
    <table>
     <tr>
         <td>名字: </td>
         <td><form:input path="name" size="20" maxlength="20" /></td>
     </tr>
     <tr>
         <td>地址: </td>
         <td><form:input path="address" size="20" maxlength="255"/></td>
     </tr>
     <tr>
         <td>座机: </td>
         <td><form:input path="telphone" size="20" maxlength="255"/></td>
     </tr>
     <tr>
         <td>手机: </td>
         <td><form:input path="mobile" size="20" maxlength="255"/></td>
     </tr>
     <tr>
         <td>邮箱: </td>
         <td><form:input path="email" size="20" maxlength="255"/></td>
     </tr>
</table>
<button type="submit">提交</button>
</form:form>
编辑页面addressEdit.jsp
<%@ include file="taglibs.jsp" %>
<h1>Add Address</h1>
<portlet:actionURL var="formAction" portletMode="edit">

         <td><form:input path="email" size="20" maxlength="255"/></td>
     </tr>
</table>
<button type="submit">提交</button>
</form:form>
EDIT模式的列表页面addressList.jsp
<%@ include file="taglibs.jsp" %>

另外几个jsp，比如error.jsp,unaailable.jsp是在出现异常的时候调用的。
