我有一个dataTable,包含具有id和phaseList属性的Package对象。我希望这个dataTable显示包ID和它的五个阶段状态与一些像彩色圆圈的图形。
例如:如果包的第一阶段完成,则在进度列中呈现的第一个圆是绿色圆,其他四个是红色圆。
所以基本上我需要根据phaseList元素属性的值渲染一个圆。我已经完成了所有这些,但在我看来应该有其他方式。问题是我必须在一个支持bean中有五个阶段颜色属性,并为这些属性设置五个getter和setter(参见下面的代码)。在那些getter中,所有五个属性的代码都非常相似,所以我认为我应该只有一个颜色属性和一个getter,并且应该以某种方式获取当前呈现圆圈的信息。
有没有其他方式(代码重复较少)来渲染这些圈子?
public class Package implements Serializable {
private static final long serialVersionUID = 1L;
private BigDecimal id;
private List<PhaseStatus> phaseList;
public BigDecimal getId() {
return id;
}
public void setId(BigDecimal id) {
this.id = id;
}
public void setPhaseList(List<PhaseStatus> phaseList) {
this.phaseList= phaseList;
}
public List<PhaseStatus> getPhaseList() {
return phaseList;
}
}
PhaseStatus类:
public class PhaseStatus implements Serializable {
private static final long serialVersionUID = 1L;
private BigDecimal phaseId;
private BigDecimal phaseStatus;
private String hint;
public void setPhaseId(BigDecimal phaseId) {
this.phaseId = phaseId;
}
public BigDecimal getPhaseId() {
return phaseId;
}
public void setPhaseStatus(BigDecimal phaseStatus) {
this.phaseStatus = phaseStatus;
}
public BigDecimal getPhaseStatus() {
return phaseStatus;
}
public void setHint(String hint) {
this.hint = hint;
}
public String getHint() {
return hint;
}
}
Xhtml代码:
<p:column headerText="Id">
<p:outputLabel value="#{item.id}" />
</p:column>
<p:column headerText="Progress">
<p:commandLink id="lnkPhase1">
<p:graphicImage library="icons" name="#{bean.phaseOneColor}" width="24px" height="24px" />
</p:commandLink>
<p:tooltip id="hint1" for="lnkPhase1" value="#{bean.phaseOneHint}" />
<p:commandLink id="lnkPhase2">
<p:graphicImage library="icons" name="#{bean.phaseTwoColor}" width="24px" height="24px" />
</p:commandLink>
<p:tooltip id="hint2" for="lnkPhase2" value="#{bean.phaseTwoHint}" />
<p:commandLink id="lnkPhase3">
<p:graphicImage library="icons" name="#{bean.phaseThreeColor}" width="24px" height="24px" />
</p:commandLink>
<p:tooltip id="hint3" for="lnkPhase3" value="#{bean.phaseThreeHint}" />
<p:commandLink id="lnkPhase4">
<p:graphicImage library="icons" name="#{bean.phaseFourColor}" width="24px" height="24px" />
</p:commandLink>
<p:tooltip id="hint4" for="lnkPhase4" value="#{bean.phaseFourHint}" />
<p:commandLink id="lnkPhase5">
<p:graphicImage library="icons" name="#{bean.phaseFiveColor}" width="24px" height="24px" />
</p:commandLink>
<p:tooltip id="hint5" for="lnkPhase5" value="#{bean.phaseFiveHint}" />
</p:column>
我的支持bean的一部分:
private String phaseOneColor;
private String phaseTwoColor;
private String phaseThreeColor;
private String phaseFourColor;
private String phaseFiveColor;
private DataTable dtPackages;
其中一个吸气者:
public String getPhaseOneColor() {
Package myPackage = (Package) getDtPackages().getRowData();
List<PhaseStatus> list = myPackage.getPhaseList();
BigDecimal status = list.get(0).getPhaseStatus();
if (status != null) {
switch (status.intValue()) {
case 1:
phaseOneColor = "green.png";
break;
default:
phaseOneColor = "red.png";
break;
}
} else {
phaseOneColor = "red.png";
}
return phaseOneColor;
}
我使用的是PrimeFaces 5.1。
答案 0 :(得分:1)
这样的事情
public String getPhaseColor(int phase) {
Package package = (Package) getDtPackages().getRowData();
List<PhaseStatus> list = package.getPhaseList();
BigDecimal status = list.get(phase).getPhaseStatus();
if (status != null) {
switch (status.intValue()) {
case 1:
phaseColor = "green.png";
break;
default:
phaseColor = "red.png";
break;
}
} else {
phaseColor = "red.png";
}
return phaseColor;
}
类似于工具提示
public String getPhaseTooltip(int phase) {
Package package = (Package) getDtPackages().getRowData();
List<PhaseStatus> list = package.getPhaseList();
BigDecimal status = list.get(phase).getPhaseStatus();
String tooltip = null;
if (status != null) {
switch (status.intValue()) {
case n:
tooltip = "Phase " + phase + " tooltip";
break;
default:
}
} else {
tooltip = "probably error";
}
return tooltip;
}
你在这样的页面中使用它
<p:column headerText="Progress">
<ui:repeat var="phase" value="#{item.phaseList}" varStatus="status">
<p:commandLink id="lnkPhase#{status.index + 1}">
<p:graphicImage library="icons" name="#{bean.getPhaseColor(status.index + 1)}" width="24px" height="24px" />
</p:commandLink>
<p:tooltip id="hint#{status.index + 1}" for="lnkPhase#{status.index + 1}" value="#{bean.getPhaseTooltip(status.index + 1)}" />
</ui:repeat>
</p:column>
代码中可能存在一些错误,因为我直接在此处输入错误,但您可以理解。

对于Java 5(参数的方法调用不起作用),你可以这样做
public Map<Integer, String> getPhaseColors() {
Package package = (Package) getDtPackages().getRowData();
Map<Integer, String> phaseColors = new HashMap<Integer, String>();
if (package != null) {
List<PhaseStatus> list = package.getPhaseList();
for (int i = 0; i < list.size(); i++;) {
BigDecimal ps = list.get(i).getPhaseStatus();
if (ps != null) {
phaseColors.put(i, ps.intValue() == 1 ? "green.png" : "red.png");
} else {
phaseColors.put(i, "red.png");
}
}
}
return phaseColor;
}
<p:graphicImage library="icons" name="#{bean.phaseColors[status.index + 1]}" width="24px" height="24px" />
