struts2中的ModelDriven使用

JSP提交数据：

<s:form action="modelDrivenResult" method="POST" namespace="/modelDriven">  

    <s:textfield label="Gangster Name" name="name" />

    <s:textfield label="Gangster Age"  name="age" />

    <s:checkbox  label="Gangster Busted Before" name="bustedBefore" />

    <s:textarea  cols="30" rows="5" label="Gangster Description" name="description" />          

    <s:submit />

</s:form>

添加下面配置到struts.xml

    <package name="base2" namespace="/modelDriven" extends="struts-default">

        <action name="modelDrivenResult" class="ModelDrivenAction">

            <result>/Hello.jsp</result>

        </action>

    </package>

处理的action,返回模型对象Gangster。

public class ModelDrivenAction extends ActionSupport implements ModelDriven {

    public String execute() throws Exception {

        return SUCCESS;

    }

    public Object getModel() {

        return new Gangster();

    }

}

模型类

public class Gangster implements Serializable {

    private String name;

    private int age;

    private String description;

    private boolean bustedBefore;

    public int getAge() {

        return age;

    }

    public void setAge(int age) {

        this.age = age;

    }

    public boolean isBustedBefore() {

        return bustedBefore;

    }

    public void setBustedBefore(boolean bustedBefore) {

        this.bustedBefore = bustedBefore;

    }

    public String getDescription() {

        return description;

    }

    public void setDescription(String description) {

        this.description = description;

    }

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

}
