idea 插件开发记录

前言：
不要盲目的复制粘贴，我的版本比较高，很多语法不兼容！！！

代码：github上可查看，欢迎start

消息通知类，用于提示一些错误，或者警告

Notification notification = new Notification(StaticString.GROUP_ID, StaticString.CONTENT, NotificationType.INFORMATION);
Notifications.Bus.notify(notification);

效果图：

弹窗通知，用于提示错误或警告（会阻碍idea的运行）

Messages.showMessageDialog("内容", "标题", Messages.getInformationIcon());

效果图：

创建一个自己的toolWindow，类似idea中的通知小铃铛之类的

创建窗体之后就可根据自己的需求进行组件拖拽

//创建一个自己的windowsFactory，之后实现createToolWindowContent方法，将自己创建的窗体添加到idea中
public class TempPluginWindowsFactory implements ToolWindowFactory {
    @Override
    public void createToolWindowContent(@NotNull Project project, @NotNull ToolWindow toolWindow) {
        TempPluginUI tempPluginUI = new TempPluginUI(project, toolWindow);
        ContentFactory contentFactory = ContentFactory.getInstance();
        Content content = contentFactory.createContent(tempPluginUI.getPanel1(), "", false);
        toolWindow.getContentManager().addContent(content);
    }
}

//注意配置！！！，在这个extensions标签下添加toolWindows
    <extensions defaultExtensionNs="com.intellij">
        <toolWindow factoryClass="com.example.tempplugin.factory.TempPluginWindowsFactory" id="tempPluginWindowsFactory" anchor="right" icon="AllIcons.Actions.Colors" />
    extensions>

效果图：

添加一个表格在toolwindows里面

请在JScrollPane下面添加table，否则会不显示table的header的

添加完成之后，在创建好的UI类中添加数据

public class TempData {
    /**
     * 创建一个表头
     */
    public static String[] HEADER = {"First Name", "Last Name", "Sport", "# of Years", "Vegetarian"};
    /**
     * 创建数据便于演示
     */
    public static Object[][] TABLE_DATA = {
            {"Kathy", "Smith", "Snowboarding", 5, false},
            {"John", "Doe", "Rowing", 3, true},
            {"Sue", "Black", "Knitting", 2, false},
            {"Jane", "White", "Speed reading", 20, true},
            {"Joe", "Brown", "Pool", 10, false}
    };
    public static DefaultTableModel DEFAULT_TABLE_MODEL = new DefaultTableModel(TABLE_DATA, HEADER);
}

使用idea插件操作编辑器中的内容，实现内容的修改

操作编辑器的方法如下：

package com.example.tempplugin.util;

import com.intellij.openapi.actionSystem.ActionManager;
import com.intellij.openapi.actionSystem.AnActionEvent;
import com.intellij.openapi.actionSystem.CommonDataKeys;
import com.intellij.openapi.command.WriteCommandAction;
import com.intellij.openapi.editor.Document;
import com.intellij.openapi.editor.Editor;
import com.intellij.openapi.editor.SelectionModel;
import com.intellij.openapi.editor.richcopy.settings.RichCopySettings;
import com.intellij.openapi.project.Project;
import com.intellij.openapi.ui.Messages;

import java.awt.*;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.StringSelection;
import java.awt.datatransfer.Transferable;

/**
 * 用于编辑选中的文本
 *
 * @author mr.ahai
 */
public class EditTextUtil {

    private EditTextUtil() {
    }

    /**
     * 将选中的内容放到剪切板中
     *
     * @return 返回选中的内容
     */
    public static String getSysClipboardText() {
        String ret = "";
        Clipboard sysClip = Toolkit.getDefaultToolkit().getSystemClipboard();
        //获取剪切板中的内容
        Transferable contents = sysClip.getContents(null);
        if (contents != null) {
            //检查是否是文本类型
            if (!contents.isDataFlavorSupported(DataFlavor.stringFlavor)) {
                return ret;
            }
            try {
                ret = (String) contents.getTransferData(DataFlavor.stringFlavor);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return ret;
    }


    /**
     * 将剪切板的内容设为空
     *
     * @param writeText 之前剪切板存在的内容
     */
    public static void setSysClipboardText(String writeText) {
        Clipboard systemClipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
        StringSelection stringSelection = new StringSelection(writeText);
        systemClipboard.setContents(stringSelection, null);
    }

    /**
     * 替换选中的文字
     *
     * @param e AnActionEvent
     */
    public static void replaceMsg(AnActionEvent e) {
        RichCopySettings settings = RichCopySettings.getInstance();
        settings.setEnabled(true);
        ActionManager.getInstance().getAction("EditorCopy").actionPerformed(e);
        settings.setEnabled(settings.isEnabled());
        String sysClipboardText = getSysClipboardText();
        //弹出一个弹框
        Messages.showMessageDialog(sysClipboardText, "您确定要替换吗", Messages.getInformationIcon());
        String tempText = "我是要替换的文字！！！！！";
        Project project = e.getData(CommonDataKeys.PROJECT);
        Editor editor = e.getData(CommonDataKeys.EDITOR);
        if (null == editor) {
            return;
        }
        e.getPresentation().setVisible(project != null && editor.getSelectionModel().hasSelection());
        Document document = editor.getDocument();
        SelectionModel selectionModel = editor.getSelectionModel();
        int start = selectionModel.getSelectionStart();
        int end = selectionModel.getSelectionEnd();
        Runnable runnable = () -> document.replaceString(start, end, tempText);
        WriteCommandAction.runWriteCommandAction(project, runnable);
        selectionModel.removeSelection();
        setSysClipboardText(sysClipboardText);
    }
}
