struts.xml中

<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<constant name="struts.devMode" value="true" /> 
<package name="basicstruts2" extends="struts-default,json-default" namespace="/">

    <action name="*act1" class="action.HWAction" method="View">     
        <result name="submit" type="json"></result>          
    </action>

Action类是HWAction.java

public class HWAction extends ActionSupport implements Action,ModelDriven<DataBean>{
DataBean ms = new DataBean();
InputBean msi = new InputBean();
//String result;

@Override
public String execute() {
    System.out.println("execute");
return SUCCESS;

}

@Override
public DataBean getModel() {
    System.out.println("getModel");        
    return ms;           
}

public String View(){

    System.out.println("Submit>"+msi);
    System.out.println("view");
    msi.getGridModel().add(ms);

    return "submit";
}

}

DataBean.java

public class DataBean {


private String name;
private String address;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}       
}

InptBean类

public class InputBean {

private String name;
private String address;

private List<DataBean> gridModel=new ArrayList<DataBean>();


public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}


public List<DataBean> getGridModel() {
    return gridModel;
}

public void setGridModel(List<DataBean> gridModel) {
    this.gridModel = gridModel;
}
