struts2.1.8 <---->struts2.0.14

[JustWhat]

1.jsp <s:form action="register"><s:textfield name="age" label="age"></s:textfield>
<s:submit value=" submit "></s:submit>
</s:form>
public class RegisterAction extends ActionSupport {
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String execute() throws Exception {
return SUCCESS;
}
}

struts.xml
<action name="register" class="com.test.action.RegisterAction">
<result>/success.jsp</result>
<result name="input">/register.jsp</result>
</action>

问题：
输入非数字，提交
当使用2.0.14的struts jar包时，不报错，直接跳回1.jsp
当使用2.1.8的struts jar 包时，tomcat console 出现错误。

恭喜楼主发现版本差异~~~

[xieshengjun2009]

就是这样的， struts2.1.8 这个版本比较好，不容易出错，建议使用。

action中没有private void setAge(String age)这个方法

action中没有private void setAge(String age)这个方法

即使添加了自定义的public void setAge(String age)这个方法

public void setAge(String age){
		try{
			this.age = Integer.parseInt(age);
		}catch(Exception ex){
			System.out.println(ex.getMessage());
			this.addFieldError("age", "input age is not a correct number");
		}
	}

还是一样啊？ 怎么解决呢？

虽然只是一个warning 但是怎么去掉啊？

首先我觉得你前端的数据本身就是要校验的.! 不管是客户端校验还是服务端校验,校验了再做action!
虽然只是一个warning,但是我觉得是你程序的漏洞, 你继承了ActionSupport,那么他会对类型转换进行校验, 而你又没有任何验证(validate method/xml校验), 转换出错他自然会跳到input视图的!

[izard999]

你这个时候不管是哪种校验方式,都应该把错误信息提示给用户!

[不姓贾_请叫我甄先生]

我看你的程序中有setAge方法呀。那么应该是jar包引起的编译错误了。

忽略客户端校验， 在服务器端的校验 重写validate method ，在做校验之前warning 就已经出来了啊。
从客户端过来的数据，struts 就已经自动的把客户端数据设到age 去。在调用setAge的时候出的warning。之后才调用vilidate method 啊

填充请求参数是paramsInterceptor做的. 这个错误肯定是这个里面来的.!

版本差异

[jumpheightway]

从2.1.3开始差异就很大了

[shenjichao2009]

我也遇到这种问题了，功能能够实现，但就是报异常！！！

Java code
public void setAge(String age){
try{
this.age = Integer.parseInt(age);
……
[/Quote]早上刚发现百度就到这了 我觉得setAge方法应该这样
public void setAge(String age) {
if(!"".equals(age))
{
this.age = Integer.parseInt(age);
}
else{
this.age=0;
}
}
在以前的版本中如果age不填在action中age自动赋值为0 看来在2.1.8版本中不填是按照String处理了而通过反射去找setAge(String ...)没有找到所以出现java.lang.NoSuchMethodException: com.test.action.RegisterAction.setAge([Ljava.lang.String;)]错误啦。
还是觉得以前的比较好 ，当然最好的方式还是在前端加校验。当然如果你使用validate（）绝对是不起作用的因为 set方法是在validate（）执行之前执行的 所以只有在前端校验或用xml了
