DataTable 没有使用 primefaces 4.0 过滤我，我想过滤 Estado 字段。

用于列出表的状态和对应信息的 Bean 方法

package com.msp.controladores;

import com.msp.modelo.Persona;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

/**

 * @author admin
 */
@ManagedBean
@SessionScoped
public class FiltroBean {

    private Persona persona;
    private List<Persona> lstPersonaFiltro;
    private List<Persona> lstPersona;

    public FiltroBean() {
        persona = new Persona();
        lstPersona = new ArrayList<>();
        lstPersona.add(new Persona(1, "Edisson", "Llinin", 28, 0));
        lstPersona.add(new Persona(2, "Juan", "Valverde", 29, 1));
        lstPersona.add(new Persona(3, "Alex", "Torres", 30, 2));
        lstPersona.add(new Persona(4, "Karla", "Malonado", 31, 3));
        lstPersona.add(new Persona(5, "Jhonatan", "Oviedo", 32, 4));
    }

    public Persona getPersona() {
        return persona;
    }

    public void setPersona(Persona persona) {
        this.persona = persona;
    }

    public List<Persona> getLstPersona() {
        return lstPersona;
    }

    public void setLstPersona(List<Persona> lstPersona) {
        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。

最佳答案 

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

filterBy 需要一个 bean 属性来过滤 

public class foo {
 private String filterMe;

 //getter and setter
}

在 getEstado 中，您返回字符串“Ninguno”，而 Ninguno 不是一个属性。

<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

关于java - 无法在 PrimeFaces DataTable 上进行过滤，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24811796/
