JSF 2默认DateTime转换器模式 [英] JSF 2 Default DateTime Converter Pattern

问题描述

我的JSF页面以以下格式显示托管bean的DateTime:"MM/dd/yyyy h:mm a"

My JSF pages display DateTime from managed beans in this format: "MM/dd/yyyy h:mm a"

我想避免在不同的页面中出现重复的转换器声明:<f:convertDateTime type="both" pattern="MM/dd/yyyy h:mm a" dateStyle="short" timeStyle="medium" />

I want avoid duplicate converter declaration in different pages: <f:convertDateTime type="both" pattern="MM/dd/yyyy h:mm a" dateStyle="short" timeStyle="medium" />

是否可以将上述转换器默认为所有DateTime字段?

Is there a way to make the above converter default for all DateTime fields?

推荐答案

只需扩展<f:convertDateTime>后面的rel ="noreferrer"> DateTimeConverter 类，并在构造函数中设置默认值.

Just extend the DateTimeConverter class behind <f:convertDateTime> and set the defaults in the constructor.

@FacesConverter("defaultDateConverter")
public class DefaultDateConverter extends DateTimeConverter {

    public DefaultDateConverter() {
        setPattern("MM/dd/yyyy h:mm a");
    }

}

用作<f:converter converterId="defaultDateConverter" />

请注意，我省略了其他属性，因为在指定pattern时，它们还是会被忽略.

Please note that I omitted other attributes as they are ignored anyway when pattern is specified.
