Question

我有一个配置bean，其中包含允许值列表：

@Component
public class Conf {
    public List<String> getAllowedValues() {
        return Arrays.asList("A", "B", "C", "D");
}

我已使用名为“someValue”的字段填充了我的邮件标题，并且我想使用过滤器元素来排除someValue不在允许值列表中的邮件。

我的上下文如下：

<int:filter expression="#{conf.allowedValues}.contains(headers.get('someValue'))"/>

但我明白了：SpelParseException: EL1041E:(pos 1): After parsing a valid expression, there is still more data in the expression: 'comma(,)'

Answer 1

答案是here：

<int:filter expression="@conf.allowedValues.contains(headers.get('someValue'))"/>

Answer 2

我得到了一个更简单（也许不是最好）的解决方案。
