DataTable不使用primefaces 4.0过滤我，我想过滤掉Estado字段。

状态的Bean方法和列出表的对应信息

        this.lstPersona = lstPersona;
    }

    public List<Persona> getLstPersonaFiltro() {
        return lstPersonaFiltro;
    }

    public void setLstPersonaFiltro(List<Persona> lstPersonaFiltro) {
        this.lstPersonaFiltro = lstPersonaFiltro;
    }

    public String getEstado(int estado) {
        if (estado == 0) {
            return "Ninguno";
        } else if (estado == 1) {
            return "Finalizado";
        } else if (estado == 2) {
            return "Iniciado";
        } else if (estado == 3) {
            return "En proceso";
        } else if (estado == 4) {
            return "Intemedio";
        }
        return null;
    }
}

请指导我实现目标的正确方法。

1 个答案:

答案 0 :(得分：1)

   <p:column filterBy="#{filtroBean.getEstado(persona.estado)}" headerText="Estado" footerText="contains" filterMatchMode="contains">

filterBy需要一个bean属性进行过滤，如

public class foo {
 private String filterMe;

 //getter and setter
}

在getEstado中，您返回字符串“Ninguno”，而Ninguno不是属性。

<p:column filterBy="#{persona.estado}" .....>

为了将int映射到String你需要写一个转换器，在PF5中你可以在p：column中使用filterFunction
