我正在尝试从参数列表中排除提交操作。以下是动作类。

@Namespace("/admin_side")
@ResultPath("/WEB-INF/content")
@InterceptorRefs({
    @InterceptorRef(value="validation", params={"excludeMethods", "test"}),
    @InterceptorRef(value="params", params={"excludeParams", "action:postAction"})})
public final class TestAction extends ActionSupport implements Serializable, ValidationAware
{
    private static final long serialVersionUID = 1L;
    private static final String SUCCESS = "success";

    private String name;

    @Action(value = "test", results = {
    @Result(name="success", location="Test.jsp"),
    @Result(name = "input", location = "Test.jsp")})
    public String test() throws Exception
    {
        System.out.println("name = "+name);
        return SUCCESS;
    }

    @Action(value = "postAction", results = {
    @Result(name="success", location="Test.jsp"),
    @Result(name = "input", location = "Test.jsp")})
    public String postAction()
    {
        System.out.println("Post invoked");
        System.out.println("name = "+name);
        return SUCCESS;
    }

    @RequiredStringValidator(type= ValidatorType.FIELD, message = "The name is required.")
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public void validate()
    {
        if(!hasErrors()&&name.length()<2)
        {
            addFieldError("name", "The name must compose of 2 letters.");
        }
    }
}

该Test.jsp页面：

<s:form namespace="/admin_side" action="test" validate="true">
    <s:textfield id="name" name="name" label="Name"/>
    <s:submit id="btnSubmit" name="btnSubmit" value="Submit" action="postAction"/>
</s:form>

生成的HTML代码<s:submit>如下所示。

<input type="submit" id="btnSubmit" name="action:postAction" value="Submit"/>

本@InterceptorRef类以上

@InterceptorRef(value="params", params={"excludeParams", "action:postAction"})

似乎不起作用。postAction()永远不会调用该方法，从而导致发出以下警告。

com.opensymphony.xwork2.interceptor.ParametersInterceptor警告警告：参数[action：postAction]在excludeParams模式列表中！

在struts.properties文件中，到目前为止，我具有以下属性。

struts.enable.DynamicMethodInvocation=false
struts.devMode=false
struts.ui.theme=simple

struts.convention.package.locators=actions
struts.convention.action.suffix=Controller
struts.convention.action.mapAllMatches=true

struts.convention.result.path=/WEB-INF/content //No need. It is the default.
struts.mapper.action.prefix.enabled=true

我正在使用Struts 2.3.16。

为什么不排除“提交”按钮的参数？单击postAction()时如何调用该方法<s:submit>？
