WELD-000072声明钝化作用域的托管bean必须具有钝化能力 [英] WELD-000072 Managed bean declaring a passivating scope must be passivation capable

问题描述

我用Java Web窗体编写了一个简单的程序，但收到以下错误：

I wrote a simple program in java web forms but i am receiving the following error:

WELD-000072托管bean声明了一个钝化范围必须具有钝化能力。 Bean：具有限定符[ @Any @Default <的托管Bean [类 BeanPakage.DemoBeans ] / code> @Named ]

WELD-000072 Managed bean declaring a passivating scope must be passivation capable. Bean: Managed Bean [class BeanPakage.DemoBeans] with qualifiers [@Any @Default @Named]

有人可以告诉我在哪里此错误来自何处？

Can anyone tell me where this error comes from?

import javax.enterprise.context.SessionScoped;
import javax.inject.Named;


@Named("DemoBeans")
@SessionScoped
public class DemoBeans {

    private String name;

    public String getName() {
        return name;
    }

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

推荐答案

您可以通过实现Serializable接口使您的bean钝化：

You can make your bean passivation capable by implementing the Serializable interface:

public class DemoBean implements Serializable { ... }

请注意，具有钝化能力还有更多要求。有关更多信息，请参阅焊接文档。

Note that there are more requirements for being passivation capable. Refer to the Weld documentation for more information.
