Struts2 Action中 两种传值方式 模型驱动Model-Driven和属性驱动Property-Driven小结

POJO（Plain Old Java Objects）简单的Java对象，实际就是普通JavaBeans，是为避免和EJB混淆所创造的简称

 

Property-Driven示例

 

标签name名与Action和POJO中名称保持一致即可

①.JSP

<s:form action="login.action" method="post" theme="simple">
<input type="text" name="userName" />
<br />
<input type="text" name="password" />
<br />
<s:submit name="login" value="登陆" method="login"></s:submit>
<s:submit name="add" value="新增" method="add"></s:submit>
</s:form>

②Action

public class LoginAction extends ActionSupport implements SessionAware,
        ServletRequestAware {
    private String userName;
    private String password;
    private String message;
    //省略get set方法

③POJO

public class User {
    private String userName;
    private String password;

Model-Driven示例

 

在Action中定义整个POJO的对象并生成get set方法，在JSP调用时候，需要在属性名前加对象名

 

①JSP

用户名:<s:textfield name="user.userName" id="user.userName"></s:textfield><br />
密码:<s:password name="user.password" id="user.password"></s:password>    <br />>

②Action

public class RegisterAction {
    private User user;

③POJO

public class User {
private String userName;
private String password;
