webwork使用spring ioc集成

蜘蛛 — Wed, 02 Aug 2006 23:29:00 GMT

在WebWork 2.2.x 之后,它将直接内徏支持spring ioc�?所以更加简单了,,
做个例子
�W�一�?在web-inf下徏一个webwork.properties文�g,
内容�?br />webwork.objectFactory = spring
�W�二�?也就是加载applicationContext.xml,可以采取前面前的两种之一,,�q�里采用后面那种


   org.springframework.web.context.ContextLoaderListener


�W�三�?创徏要装载的实例,在applicationContext.xml(采用监听的方�?��C��默认的位�|�是在web-inf下面)

�W�四�?在修�Ҏ��原来的例�?br />HelloWorldAction.java
�?br />package helloWorld;
import com.opensymphony.xwork.ActionSupport;
public class HelloWorldAction extends ActionSupport{

    String greeting;
    UserManager userManager;
    public void setGreeting(String greeting) {
        this.greeting = greeting;
    }

    public String getGreeting() {
        return greeting;
    }
    public UserManager getUserManager() {
  return userManager;
}

public void setUserManager(UserManager userManager) {
this.userManager = userManager;
}

public String execute() throws Exception {
  userManager.sayHello();
  System.out.println("after userManager.sayHello()");
        if (greeting.equals("") || greeting == null) {
            addFieldError("greeting", getText("greeting"));
            return ERROR;
        }
        return SUCCESS;
    }
}
而UserManager.java�c�d��?br />package helloWorld;
public class UserManager {
public UserManager()
{
System.out.println("create instance of UserManger");
}
public void sayHello()
{
System.out.println("hello zjh");
}
}
再访�?a href="http://localhost:8080/WebWork/index.jsp">http://localhost:8080/WebWork/index.jsp提交后在tomcat console�H�口打印�?br />hello zjh
after userManager.sayHello()

webwork 学习�?validation验证框架)

蜘蛛 — Wed, 02 Aug 2006 14:10:00 GMT

webwork使用 validation验证框架�Q�其采用的是拦截�?br />看一个例�?

SimpleAction-validation.xml 名字前缀要与�c�d��相同�Q�而且与之在同一目录�?/b>



            You must enter a value for count.


            0
            5

    count must be between ${min} and ${max}, current value is ${count}.




==
package helloWorld;
import com.opensymphony.xwork.ActionSupport;
import com.opensymphony.xwork.ValidationAware;

public class SimpleAction extends ActionSupport implements ValidationAware {

private int count;

    public void setCount(int count) {
        this.count = count;
    }

    public int getCount() {
        return count;
    }

    public String doExecute() throws Exception {
   return SUCCESS;
    }
}
------
在xwork.xml里面��d��


    /simple_result.jsp


    /simple.jsp



    /simple.jsp






注意interceptor为多个时与servlet里面的filter一��h��序依次传�?假若��p�|��׃ؓ影响后面的程序运行效�?
�q�有两个jsp��面
simple_result.jsp
<%@ taglib prefix="ww" uri="webwork"%>

  WebWork Validation Example



   The count is





--
simple.jsp
<%@ taglib prefix="ui" uri="webwork" %>

    WebWork Validation Example




�q�行效果如下
count must be between 0 and 5, current value is 8.
Set the counter:

下面为日期类型的验证

12/22/2002
12/25/2002
The date must be between 12-22-2002 and 12-25-2002.

0
100
Could not find foo.range!

webwork学习一

�?/span> struts 的区别有实现国��化的时候， struts �?/span> message 只能出现 5 个动态的�?/span>

也就像下面的信息

Your {0} ticket(s) for flight {1} have been booked.

The total cost is {2}. Your confirmation number is {3}.

Your flight leaves at {4} and arrives at {5}

需要分成两�D�|��能完�?/font>

arg0="count" arg1="flightNumber" arg2="cost"/>

arg0="confirmation" arg1="departure" arg2="arrival"/>

�?/span> webwork 是无限制的，像上面的可以写成�q�样�?/span>

�q�有在web.xml里同指定webwork的tld所在位�|?br />

webwork

/WEB-INF/lib/webwork-2.1.7.jar

在很多书上都讲上面可行，可是我却报下面的错．�Q�．换成下面那种方式��ok�?br />
org.apache.jasper.JasperException: Unable to initialize TldLocationsCache: null
也可以指定webwork.tld所在的位置也可以，�Q�如
/WEB-INF/webwork.tld(webwork.tld拷到�q�下面来).

一个简单的例子

import com.opensymphony.xwork.Action;
public class HelloWorldAction implements Action{
    String greeting;
    public String getGreeting() {
        return greeting;
    }
    public String execute() throws Exception {
        greeting = "Hello World!";
        return SUCCESS;
    }
}
实现的action接口里面只有一个方�?br />
interface Action {
String execute() throws Exception;
}
greetings.jsp
<%@ taglib prefix="ww" uri="webwork" %>

    First WebWork Example

xwork.xml 攑ֈ��q��的classpath下面(也就web-inf/classes下面)

/greetings.jsp

�q�有在web.xml里面加上webwork的一个加载类

        action
        com.opensymphony.webwork.dispatcher.ServletDispatcher



        action
        *.action


ActionSupport

1:提供寚w��误信息的支持

�?/strong> action and field specific errors

�?/strong> field errors are automatically supported by views

�?/strong> 2:国际化的支持

�?/strong> 1 resource bundle per action

�?/strong> pervasive UI support for retrieving messages
--------------------------------------------------------------------------------
ActionSupport Example:
import com.opensymphony.xwork.ActionSupport;
public class HelloWorldAction extends ActionSupport{
    String greeting;
    public void setGreeting(String greeting) {
        this.greeting = greeting;
    }
    public String getGreeting() {
        return greeting;
    }
    public String execute() throws Exception {
        if (greeting.equals("") || greeting == null) {
            addFieldError("greeting", getText("greeting"));
            return ERROR;
        }
        return SUCCESS;
    }
}
�q�里的getText("greeting")的greeting要与HelloWorldAction.properties(攑֜�与HelloWorldAction.class同��目录下面�Q�名�U�C��一�?里的greeting=Enter your greeting please相同
上面的set.get其实与struts当中的ActionFrom�c�M��Q�．
<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
<%@ taglib prefix="ui" uri="webwork" %>

    First WebWork Example




�q�里的greeting要与HelloWorldActio.java里的属性一�?br />如出现错误会昄��在当前页�Q?br />
Enter your greeting please
�Ƣ迎语句:

如填上内容，��׃��相应的调用setGreeting()�Ҏ��的．�Q?br /><%@ taglib prefix="ww" uri="webwork" %>

    First WebWork Example

把填的内�Ҏ��C�出�?br />在xwork.xml里的
也相应的变成


    /greetings.jsp


          /index.jsp


------------------------------------------------------------

Model-Driven Actions vs. Field-Driven Actions
�?/span>
2 types of Actions possible:
(1)Field-Drivern上面的例子就�?br />(2)ModelDriven
package helloWorld;
public class Pet {
    private long id;
private String name;
    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}
--
package helloWorld;
import com.opensymphony.xwork.*;
public class AddPetAction extends ActionSupport implements ModelDriven{
Pet pet = new Pet();
    public Object getModel() {
        return pet;
    }
    protected void doValidation() {
        if (pet.getId() == 0) {
            addFieldError("id", "Please enter in an id number for you new Pet.");
        }
    }
    public String doExecute() throws Exception {
        if (hasErrors())
            return ERROR;
        return SUCCESS;
    }

}
需实现ModelDriven�q�个接口�Q�它也只有一个方�?br />public Object getModel();
在xwork.xml加上


    /petadded.jsp


    /addpet.jsp




�q�有两个��面分别用来��d��和显�C�用�?br /><%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="ui" uri="webwork" %>

    First WebWork Example





-------petadded.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="ww" uri="webwork" %>

    First WebWork Example

Added a pet with the following properties:
