插件描述

CodeMemo 是一个为 IntelliJ IDEA 设计的备忘录插件，旨在简化开发工作流程，提供一个集中式存储库来管理和存储各种类型的代码和文本片段。

功能特点

• 无缝集成：与 IntelliJ IDEA 紧密集成，可以直接从 IDE 访问代码片段。
• 简便管理：通过直观的界面轻松添加、删除和管理代码片段。
• 搜索功能：支持关键字和内容搜索，快速查找需要的代码片段。

主打一个内聚性，开发的事就在IDE中完成，不要再过度耦合谷歌去搜索一些重复性的代码模板了，如redis配置等

开发流程概述

详细开发流程可参阅官方文档：plugins.jetbrains.com/docs/intell…

详细代码在仓库中，可相互印证学习

安装插件开发环境

新建项目，创建并配置Anction

java

复制代码
/**
 * @author ZJamss
 * @date 2024/6/15
 */
public class CodeMemoAction extends AnAction {

    @Override
    public void update(AnActionEvent e) {
        // Set the availability based on whether a project is open
        Project project = e.getProject();
        e.getPresentation().setEnabledAndVisible(project != null);
    }

    @Override
    public void actionPerformed(@NotNull AnActionEvent event) {
    
        // 显示插件主界面(代码在后面提供)
        CodeMemoSaverDialog codeMemoSaverDialog = new CodeMemoSaverDialog(event.getProject());
        DialogBuilder dialogBuilder = new DialogBuilder();
        dialogBuilder.setCenterPanel(codeMemoSaverDialog.getMainPanel());
        dialogBuilder.setTitle(event.getPresentation().getText());
        dialogBuilder.show();
    }

    @Override
    public @NotNull ActionUpdateThread getActionUpdateThread() {
        return super.getActionUpdateThread();
    }
}

在plugin.xml中配置Action

xml

复制代码
<actions>
    <action id="cn.zjamss.plugin.codeMemo.CodeMemoAction" class="cn.zjamss.plugin.codeMemo.CodeMemoAction"
            text="Code Memo"
            description="A tool for saving, searching, deleting snippets effortlessly in your IDE.">
        <add-to-group group-id="EditorPopupMenu" anchor="last"/> <!--选择插件action位置，这里是右键菜单-->
    </action>
</actions>

完成这两步，运行插件->右键菜单->点击插件项 即可看到主界面

完成UI界面开发

UI开发其实就是Java Swing开发

主界面 CodeMemoSaverDialog

java

复制代码
public class CodeMemoSaverDialog {
    private final JPanel mainPanel;
    private final JPanel buttonPanel;
    private final JButton addButton;
    private final JTextField searchField;
    private final Map<String, JButton> mMemoButtons;
    private final Project project;
    private MemoInfoDialog memoInfoDialog;


    // Initialize window
    // 配置布局等等
    public CodeMemoSaverDialog(Project project) {
        this.project = project;
        mainPanel = new JPanel(new BorderLayout());
        buttonPanel = new JPanel();
        addButton = new JButton("Add Code Memo");
        searchField = new JTextField(10);
        mMemoButtons = new HashMap<>();

        searchField.setMaximumSize(
            new Dimension(Integer.MAX_VALUE, addButton.getPreferredSize().height));
        addButton.setMaximumSize(
            new Dimension(Integer.MAX_VALUE, addButton.getPreferredSize().height));
        addButton.setAlignmentX(Component.CENTER_ALIGNMENT);

        buttonPanel.setLayout(new BoxLayout(buttonPanel, BoxLayout.Y_AXIS));

        JScrollPane buttonScrollPane =
            new JBScrollPane(buttonPanel, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
                JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
        buttonScrollPane.setPreferredSize(new Dimension(200, 400));


        mainPanel.setPreferredSize(new Dimension(600, 400));
        mainPanel.add(buttonScrollPane, BorderLayout.WEST);

        initializeMemoInfoPanel();

        registerEvents();
        loadMemos();
    }
    // ... 其余代码略
}

其余UI组件代码略，详细可查看仓库代码

持久化

定义实体类CodeMemo

java

复制代码
/**
 * @author ZJamss
 * @date 2024/6/13
 */
public class CodeMemo {
    private String name;
    private String codeType;
    private String codeContent;

    // Default constructor for serialization
    public CodeMemo() {}

    public CodeMemo(String name, String codeType, String codeContent) {
        this.name = name;
        this.codeType = codeType;
        this.codeContent = codeContent;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getCodeType() {
        return codeType;
    }

    public void setCodeType(String codeType) {
        this.codeType = codeType;
    }

    public String getCodeContent() {
        return codeContent;
    }

    public void setCodeContent(String codeContent) {
        this.codeContent = codeContent;
    }
}

使用IntelliJ Plugin API完成持久化配置

java

复制代码
/**
 * @author ZJamss
 * @date 2024/6/13
 *
 * <p>
 * GlobalCodeMemoSaverSettings is a singleton class responsible for persisting code memo data
 * using IntelliJ IDEA's persistent state component framework.
 * </p>
 */
@State(
    name = "GlobalCodeMemoSaverSettings",
    // 保存的文件名
    storages = @Storage("globalCodeMemoSaverSettings.xml")
)
@Service(Service.Level.APP)
public final class GlobalCodeMemoSaverSettings
    implements PersistentStateComponent<GlobalCodeMemoSaverSettings> {
    // 声明数据
    private List<CodeMemo> notes = new ArrayList<>();

    public GlobalCodeMemoSaverSettings() {
    }

    @Nullable
    @Override
    public GlobalCodeMemoSaverSettings getState() {
        return this;
    }

    // 重写方法，从xml文件中加载数据，自动调用
    @Override
    public void loadState(@NotNull GlobalCodeMemoSaverSettings state) {
        XmlSerializerUtil.copyBean(state, this);
    }

    public static GlobalCodeMemoSaverSettings getInstance() {
        return ApplicationManager.getApplication().getService(GlobalCodeMemoSaverSettings.class);
    }


    // 自定义对数据的操作
    public void setMemos(List<CodeMemo> notes) {
        this.notes = notes;
    }

    public List<CodeMemo> getMemo() {
        return notes;
    }

    public void addMemo(CodeMemo codeMemo) {
        notes.add(codeMemo);
    }

    public void deleteMemoByName(String name) {
        notes.removeIf(memo -> memo.getName().equals(name));
    }
}

由此通过插件API可以完成对数据的持久化

配置数据服务

在plugin.xml中配置应用程序服务

xml

复制代码
<extensions defaultExtensionNs="com.intellij">
    <applicationService serviceImplementation="cn.zjamss.plugin.codeMemo.persistent.GlobalCodeMemoSaverSettings"/>
</extensions>
