Question

我试图通过params拦截器设置多个可接受的参数，如下所示。

@Namespace("/admin_side")
@ResultPath("/WEB-INF/content")
@InterceptorRefs({
    @InterceptorRef(value="defaultStack", 
        params={"params.excludeParams", "^action:(?!postAction$)\\w*$",
        "params.acceptParamNames", "action:postAction",
        "params.acceptParamNames", "id",
        "params.acceptParamNames", "name",
        "params.acceptParamNames", "email",
        "params.acceptParamNames", "number",
        "params.acceptParamNames", "deleteOneRow",        
        "validation.excludeMethods", "test"}),            
})
public final class TestAction extends ActionSupport implements Serializable, ValidationAware, ModelDriven<Transporter>
{
    //...
}

在这种情况下，只接受deleteOneRow（Boolean）的最后一个参数。其余的不被接受。相反，它发出如下警告。

如何使用约定插件将多个参数设置为params.acceptParamNames？

Answer 1

所以，答案很简单如下。

@InterceptorRefs({
    @InterceptorRef(value="defaultStack", 
    params={"params.excludeParams", "^action:(?!postAction$)\\w*$",
   "params.acceptParamNames", "^action:(?!postAction$)\\w*$, id, name, email, number, deleteOneRow", 
    "validation.excludeMethods", "test"})
})

在这些参数中，^action:(?!postAction$)\\w*$是提交按钮的参数，<s:submit>无法发出警告WARNING: Parameter [action:postAction] didn't match acceptParams list of patterns!，但可能是另一个问题。

如何使用注释（约定插件）在Struts2中指定多个acceptParamNames？
