求解：使用ssh框架，为何调试时得不到画面上输入的值？

fedoriri 2012-08-14 06:55:13

ssh框架是自己用eclipse搭建的，断点调试时发现model里的msg的值为null，不知道为什么画面输入了值却传不到model中？求高手提示哈。
-------------ACTION类---------------
public class TESTACTION extends ActionSupport {
private static final long serialVersionUID = 1L;

private TESTMODEL model;
@Override
public String execute() throws Exception {
if ("badBoy".equals(this.model.getMsg())){
return ActionSupport.SUCCESS;
}else
{
return ActionSupport.ERROR;
}
}

public TESTMODEL getModel() {
return model;
}

public void setModel(TESTMODEL model) {
this.model = model;
}
}
----------model类---------------------
public class TESTMODEL {
private String msg;

public String getMsg() {
return msg;
}

public void setMsg(String msg) {
this.msg = msg;
}

}

这里<input type="text" name ="msg"></input>
换成<input type="text" name ="model.msg"></input>

strut的配置文件发上来看看，按理来说用eclipse搭的话JSP的很多标签都会自己生成的

为什么需要写成这样啊？只写msg，model为什么不能自动得到值？

要通过TESTACTION 类定义一个对象，让对象调用getMsg()才能取到值。

TESTACTION<T extends TESTMODEL> extends ActionSupport implements ModelDriven<T>
{
private T model;
public T getModel() {
return model;
}

public void setModel(T model) {
this.model = model;
}
}
