struts2中关于传值问题

你在页面上 写个字段 然后传给后台action action中只要有该属性的setter/getter方法 就不用写request.setAttribute() 跳转的页面 可以获取到值（重定向不可以 type必须是chain）

普通字段 或者简单的对象都可以

代码如下（不喜勿喷）

----------------------action类---------------------------------------------

public class TestValueAction extends ActionSupport {
public User user;
public String name;
public String address;
public String test(){
return "test";
}
public String test2(){
return "test2";
}
public User getUser() {
return user;
}

public void setUser(User user) {
this.user = user;
}

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;
}
}

-----------------------配置文件--------------------------------

<action name="testValueAction_*" class="cn.gdpe.controller.TestValueAction" method="{1}">
<!-- 重定向 -->
<result name="test2">/test.jsp</result>
<result name="test" type="redirect">testValueAction_test2.action</result>
<!--转发
<result name="test1">/test.jsp</result> -->
</action>

------------------------页面-1-------------------------------------

<form action="${pageContext.request.contextPath }/testValueAction_test.action">
<input type="text" name="name"/>
<input type="text" name="address"/>
<input type="text" name="user.name"/>
<input type="text" name="user.address"/>
<input type="submit" value="提交">
</form>

--------------------页面-2-------------------------------------------

${user.name }
${user.address }
${name }
${address }

-------------------------USER类-----------------------------

public class User {
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;
}

}
