Question

我有一个包含String和BigDecimal类型字段的类。当显示BigDecimal作为分隔符时，我想要成为逗号。我改变了波兰语的编码，但仍然是点。当我使用<f:convertNumber locale=""#{language.locale}"/>工作正常，但不想在每个领域都这样做，因为我有很多这样做

实现这一目标的最佳方法是什么？

面-config.xml中

<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.2"
              xmlns="http://xmlns.jcp.org/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">
    <application>
        <locale-config>
            <default-locale>pl</default-locale>
        </locale-config>
    </application>
</faces-config>

Language.java

@Named
@SessionScoped
public class Language implements Serializable {

    private Locale locale;

    @PostConstruct
    public void init() {
        locale = FacesContext.getCurrentInstance().getApplication().getDefaultLocale();
    }

    public Locale getLocale() {
        return locale;
    }

    public void setLocale(Locale locale) {
        this.locale = locale;
    }

}

您需要以某种方式转换为您的语言环境

当我使用<f:convertNumber locale=""#{language.locale}"/>时工作正常，但不想在每个领域都这样做，因为我有很多这样做

因此，如果您不想在客户端执行此操作，则需要向bean添加getLocaleNumber()（或类似）方法，以便以所需格式显示数字：

public String getLocalized(BigDecimal number) throws Exception {
    // get desired locale (maybe a constant will suit you better)
    NumberFormat nf = NumberFormat.getInstance(new Locale("pl_PL"));
    return nf.format(number.doubleValue());
}
