我想在數據表中有一個selectonemenu作爲過濾器選項 我已經做了幾個測試，沒有成功 現在我試圖創建一個示例自定義經過過濾，利用selectOneButton，與靜態字段，試圖簡化，但同樣它不工作總理面孔5.0：數據表中的自定義過濾器被忽略
<p:column filterBy="#{sController.getStatus(se)}" headerText="Stato"
style="text-align:center;" sortBy="#{sController.getStatus(se)}"
filterMatchMode="exact"
>
<f:facet name="filter">
<p:selectOneButton onchange="PF('sDataTableWV').filter()">
<f:converter converterId="javax.faces.Boolean" />
<f:selectItem itemLabel="All" itemValue="" />
<f:selectItem itemLabel="Sold" itemValue="true" />
<f:selectItem itemLabel="Sale" itemValue="false" />
</p:selectOneButton>
</f:facet>
<img src="#{resource[sController.getStatus(se)]}" />
</p:column>
小面完全被忽略，我看到常用的輸入字段，而不是

</html>這裏Car.java
package controllers.test;
import java.io.Serializable;
public class Car implements Serializable {
public String id;
public String brand;
public int year;
public String color;
public int price;
public boolean sold;
public Car() {}
public Car(String id, String brand, int year, String color) {
this.id = id;
this.brand = brand;
this.year = year;
this.color = color;
}
public Car(String id, String brand, int year, String color, int price, boolean sold) {
this.id = id;
this.brand = brand;
this.year = year;
this.color = color;
this.price = price;
this.sold = sold;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public int getYear() {
return year;
}
public void setYear(int year) {
this.year = year;
}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public boolean isSold() {
return sold;
}
public void setSold(boolean sold) {
this.sold = sold;
}
@Override
public int hashCode() {
int hash = 7;
hash = 59 * hash + (this.id != null ? this.id.hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object obj) {
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final Car other = (Car) obj;
if ((this.id == null) ? (other.id != null) : !this.id.equals(other.id)) {
return false;
}
return true;
}
}
然後CarService.java
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.UUID;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
@ManagedBean(name = "carService")
@ApplicationScoped
public class CarService {
private final static String[] colors;
private final static String[] brands;
static {
colors = new String[10];
colors[0] = "Black";
colors[1] = "White";
colors[2] = "Green";
colors[3] = "Red";
colors[4] = "Blue";
colors[5] = "Orange";
colors[6] = "Silver";
colors[7] = "Yellow";
colors[8] = "Brown";
colors[9] = "Maroon";
brands = new String[10];
brands[0] = "BMW";
brands[1] = "Mercedes";
brands[2] = "Volvo";
brands[3] = "Audi";
brands[4] = "Renault";
brands[5] = "Fiat";
brands[6] = "Volkswagen";
brands[7] = "Honda";
brands[8] = "Jaguar";
brands[9] = "Ford";
}
public List<Car> createCars(int size) {
List<Car> list = new ArrayList<Car>();
for(int i = 0 ; i < size ; i++) {
list.add(new Car(getRandomId(), getRandomBrand(), getRandomYear(), getRandomColor(), getRandomPrice(), getRandomSoldState()));
}
return list;
}
private String getRandomId() {
return UUID.randomUUID().toString().substring(0, 8);
}
private int getRandomYear() {
return (int) (Math.random() * 50 + 1960);
}
private String getRandomColor() {
return colors[(int) (Math.random() * 10)];
}
private String getRandomBrand() {
return brands[(int) (Math.random() * 10)];
}
public int getRandomPrice() {
return (int) (Math.random() * 100000);
}
public boolean getRandomSoldState() {
return (Math.random() > 0.5) ? true: false;
}
public List<String> getColors() {
return Arrays.asList(colors);
}
public List<String> getBrands() {
return Arrays.asList(brands);
}
}
和最後FilterView.java
import java.io.Serializable;
import java.util.List;
import java.util.Locale;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.ViewScoped;
@ManagedBean(name="dtFilterView")
@ViewScoped
public class FilterView implements Serializable {
private List<Car> cars;
private List<Car> filteredCars;
@ManagedProperty("#{carService}")
private CarService service;
@PostConstruct
public void init() {
cars = service.createCars(10);
}
public boolean filterByPrice(Object value, Object filter, Locale locale) {
String filterText = (filter == null) ? null : filter.toString().trim();
if(filterText == null||filterText.equals("")) {
return true;
}
if(value == null) {
return false;
}
return ((Comparable) value).compareTo(Integer.valueOf(filterText)) > 0;
}
public List<String> getBrands() {
return service.getBrands();
}
public List<String> getColors() {
return service.getColors();
}
public List<Car> getCars() {
return cars;
}
public List<Car> getFilteredCars() {
return filteredCars;
}
public void setFilteredCars(List<Car> filteredCars) {
this.filteredCars = filteredCars;
}
public void setService(CarService service) {
this.service = service;
}
}
結果是完全一樣的，過濾器輸入字段
我在用5.0的GlassFish 3.2
