在以下有关Struts动作类的代码中，

@Namespace("/admin_side")
@ResultPath("/WEB-INF/content")  // Default.

public final class TestAction extends ActionSupport implements Serializable
{
    private static final long serialVersionUID = 1L;
    private static final String SUCCESS = "success";

    private String name;
    private String email;

    public String getName() {
        return name;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

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

    // Some annotations to map this method to <s:submit>
    public String postAction()
    {
        System.out.println("postAction() invoked.");
        System.out.println("name = "+name);
        System.out.println("email = "+email);
        return SUCCESS;
    }
}

我想像这样postAction()在给定的提交按钮上调用方法，

<s:form action="test">
    <s:textfield id="name" name="name" label="Enter your name"/>
    <s:textfield id="email" name="email" label="Enter your email"/>

    <s:submit value="Submit" method="postAction"/>
</s:form>

我曾见过这样一些问题这一个，但是所有的人都在使用XML配置struts.xml。

如何 使用Conventional插件 使其成为可能？
