我目前正在研究JAVA FX应用程序，以从JIRA REST API获取用户的信息。我想要一个刷新按钮，点击它时，必须使用新添加的数据显示表格视图 请看一下代码。 我的POJO课程 公共课问题{
private String jiraKey;
private String jiraSummary;
private String jiraPriority;
private String jiraAssignee;
private String jiraIssueType;
private Hyperlink hyperLink;
private String loghours;
private String commentLogHours;
public Issues(String jiraKey, String jiraSummary, String jiraPriority, String jiraAssignee, String jiraIssueType) {
super();
this.hyperLink = new Hyperlink(jiraKey);
this.jiraSummary = jiraSummary;
this.jiraPriority = jiraPriority;
this.jiraAssignee = jiraAssignee;
this.jiraIssueType = jiraIssueType;
this.hyperLink = hyperLink;
this.loghours = loghours;
this.commentLogHours = commentLogHours;
}
public String getJiraKey() {
return jiraKey;
}
public void setJiraKey(String jiraKey) {
this.jiraKey = jiraKey;
}
//getters and setters
}
我的Observable list方法，用于将数据填充到表
Class ABC{
public ObservableList<Issues> issueJsonList(){
// A processed arraylist
ObservableList<Issues> data = FXCollections.observableList(list);
return data;
}
}
这是我的tableview代码。
@SuppressWarnings({ "unchecked", "rawtypes" })
public TableView<Issues> initTable() throws IOException, URISyntaxException {
TableView<Issues> table = new TableView<Issues>();
table.setEditable(true);
TableColumn<Issues, Hyperlink> jiraKey = new TableColumn<>(keyField);
jiraKey.setCellValueFactory(new PropertyValueFactory("hyperLink"));
jiraKey.setCellFactory(new HyperlinkCell());
TableColumn jiraPriority = new TableColumn(priorityField);
TableColumn jiraIssueType = new TableColumn(issueTypeField);
TableColumn jiraSummary = new TableColumn(summaryField);
TableColumn jiraAssignee = new TableColumn(assigneeField);
TableColumn workLogCol = new TableColumn(workLogField);
TableColumn timeSpent = new TableColumn(timeSpentField);
TableColumn commentTimeLog = new TableColumn(commentField);
workLogCol.getColumns().addAll(timeSpent, commentTimeLog);
jiraSummary.setCellValueFactory(new PropertyValueFactory("jiraSummary"));
jiraIssueType.setCellValueFactory(new PropertyValueFactory("jiraIssueType"));
jiraPriority.setCellValueFactory(new PropertyValueFactory("jiraPriority"));
jiraAssignee.setCellValueFactory(new PropertyValueFactory("jiraAssignee"));
timeSpent.setCellValueFactory(new PropertyValueFactory("getTimeSpent"));
timeSpent.setCellFactory(TextFieldTableCell.forTableColumn());
commentTimeLog.setCellValueFactory(new PropertyValueFactory("getComment"));
commentTimeLog.setCellFactory(TextFieldTableCell.forTableColumn());
timeSpent.setOnEditCommit(new EventHandler<CellEditEvent<JiraAuth, String>>() {
public void handle(CellEditEvent<JiraAuth, String> t) {
JiraAuth.setTimeSpent(t.getNewValue());
}
});
commentTimeLog.setCellFactory(TextFieldTableCell.forTableColumn());
commentTimeLog.setOnEditCommit(new EventHandler<CellEditEvent<JiraAuth, String>>() {
public void handle(CellEditEvent<JiraAuth, String> t) {
JiraAuth.setWorkLogComment(t.getNewValue());
int i = t.getTablePosition().getRow();
String abc = table.getColumns().get(0).getCellData(i).toString();
String finalStr = abc.substring(abc.indexOf("]") + 1);
JiraAuth.setWorkLogJiraKey(finalStr);
}
});
table.getColumns().setAll(jiraKey, jiraSummary, jiraPriority, jiraAssignee, jiraIssueType);
IssuesJsonParser issueObject = new IssuesJsonParser();
ObservableList<Issues> data = issueObject.issueJsonList();
table.setItems(data);
table.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
return table;
}
调用刷新按钮时，
buttons[0] = new Button("Refresh");
buttons[0].setOnAction(event->{
initTable().refresh();
});
