Question

我的枚举问题。

这是：

public enum DataEnum {
    NAME_PEOPLE("NAME_PEOPLE"),
    FIRSTNAME_PEOPLE("FIRSTNAME_PEOPLE"),
    ID("ID"),
    PASS("PASS"),
    NEW_MAIL("NEW_MAIL");

    private  String name;
    private DataEnum(String s) {
        name = s;
    }
    public String getValue() {
        return name;
    }
    public void setValue(String s) {
        this.name = s;
    }
}

我在那里使用它：

public String transform(String textToTransform, People people){
        Pattern TAG_REGEX = Pattern.compile("#(.+?)#");
        Matcher matcher = TAG_REGEX.matcher(textToTransform);
        while (matcher.find()) {
            String s = matcher.group(1);
            switch (s) {
                case "FIRSTNAME_PEOPLE":
                    DataEnum.valueOf(s).setValue(people.getFirstName());
                    break;
                case "NAME_PEOPLE":
                    DataEnum.valueOf(s).setValue(people.getName());
                    break;
                case "ID":
                    DataEnum.valueOf(s).setValue(people.getEmail());
                    break;
                case "PASS":
                    DataEnum.valueOf(s).setValue(people.getPassword());
                    break;
                default:
                    break;
            }
            textToTransform = textToTransform.replace("#" + DataEnum.valueOf(s) + "#", DataEnum.valueOf(s).getValue());
        }
        return textToTransform;
    }

我收到以下错误：

引起：java.lang.IllegalArgumentException：没有枚举常量 fr.pdf.utils.DataEnum.FIRSTNAME_PEOPLE

编辑：

引起：java.lang.IllegalArgumentException：没有枚举常量 fr.pdf.utils.DataEnum.FIRSTNAME_PEOPLE at java.lang.Enum.valueOf（Enum.java:238）at fr.pdf.utils.DataEnum.valueOf（DataEnum.java:3）在 fr.pdf.services.impl.MailServiceImpl.transform（MailServiceImpl.java:160）在 fr.pdf.services.impl.MailServiceImpl.sendMail（MailServiceImpl.java:84）在 fr.pdf.dao.impl.People.update（People.java:372）

第160行对应于：

textToTransform = textToTransform.replace("#" + DataEnum.valueOf(s) + "#", DataEnum.valueOf(s).getValue());

删除枚举并执行此操作：）

public String transform(String textToTransform, People people){
    Pattern TAG_REGEX = Pattern.compile("#(.+?)#");
    Matcher matcher = TAG_REGEX.matcher(textToTransform);
    while (matcher.find()) {
        String s = matcher.group(1);
        String replaceWith = null;
        switch (s) {
            case "FIRSTNAME_PEOPLE":
                replaceWith = people.getFirstName();
                break;
            case "NAME_PEOPLE":
                replaceWith = people.getName();
                break;
            case "ID":
                replaceWith = people.getEmail();
                break;
            case "PASS":
                replaceWith = people.getPassword();
                break;
            default:
                break;
        }
        textToTransform = textToTransform.replace("#" + s + "#", replaceWith);
    }
    return textToTransform;
}

java.lang.IllegalArgumentException：没有枚举常量
