# 前言 {#前言}
在IDEA插件开发系列的上一篇文章中,我介绍了ConvertX插件是如何实现的。因为ConvertX插件没有涉及UI相关的内容,因此在这一篇文章中,我会带大家一起做一个包含UI内容的插件,一个能看股票的插件。
# 插件效果 {#插件效果}
首先是在设置中配置股票的编号,如sh000001,sh600519。
接着在侧边栏中有一个叫做Stock Prices的Tab框,点击之后,设置的这几个股票就出现了
当点击刷新按钮之后,就会重新刷新数据,上边的最新更新日期也会同步变化。
# 源码地址 {#源码地址}
代码已在github开源,可以直接访问,大家觉得有用的点点star哦:https://github.com/OliverLiy/StockWatch
# 项目结构 {#项目结构}
首先还是先看一下项目结构:
从上到下依次介绍:
- 1、StockSettingsComponent保存了配置页面的样式。
- 2、StockConfigurable是配置页面的配置类,加载了StockSettingsComponent这个组件。
- 3、handler里的是一个OkHttp的单例实现类,以及调用股票接口的处理器,response是接口的返回。
- 4、StockSettingsState中保存的是配置的持久化内容,这个文件会保存在本地。
- 5、StockToolWindow是在侧边栏展示的内容,也就是最终看到的效果。
所有的图都是用javax.swing画的,如果想实现更加多的功能,可以把这块代码好好看看。
# 配置功能的实现 {#配置功能的实现}
配置功能要做的事情是把股票编号的配置交给用户自己,首先定义了一个配置的持久化类叫做StockSettingsState
import com.intellij.openapi.components.PersistentStateComponent;
import com.intellij.openapi.components.ServiceManager;
import com.intellij.openapi.components.State;
import com.intellij.openapi.components.Storage;
import org.jetbrains.annotations.NotNull;
import org.jetbrains.annotations.Nullable;
/**
* @author by: 神秘的鱼仔
* @ClassName: StockSettingsState
* @Description: 股票配置的持久化类
* @Date: 2024/7/5 下午4:17
*/
@State(
name = "top.codeease.stockwatch.storage.StockSettingsState",
storages = @Storage("StockPluginSettings.xml")
)
public class StockSettingsState implements PersistentStateComponent<StockSettingsState> {
/**
* 默认股票符号,取上证指数
*/
public String stockSymbol = "sh000001";
public static StockSettingsState getInstance() {
return ServiceManager.getService(StockSettingsState.class);
}
@Nullable
@Override
public StockSettingsState getState() {
return this;
}
@Override
public void loadState(@NotNull StockSettingsState state) {
this.stockSymbol = state.stockSymbol;
}
}
这个持久化文件最终会保存在本地。
接着定义一个组件类叫做StockSettingsComponent,就用一个JPanel包裹一个JTextField。
import javax.swing.*;
/**
* @author by: 神秘的鱼仔
* @ClassName: StockSettingsComponent
* @Description: 设置组件类
* @Date: 2024/7/5 下午4:03
*/
public class StockSettingsComponent {
private JPanel panel;
private JTextField stockSymbolTextField;
public StockSettingsComponent() {
panel = new JPanel();
stockSymbolTextField = new JTextField(40);
panel.add(new JLabel("请输入股票编号(用英文逗号分割):"));
panel.add(stockSymbolTextField);
}
public JPanel getPanel() {
return panel;
}
public String getStockSymbol() {
return stockSymbolTextField.getText();
}
public void setStockSymbol(String stockSymbol) {
stockSymbolTextField.setText(stockSymbol);
}
}
最后就是一个配置类将上面两个类拼装起来了,代码比较简单,大家看了就可以看懂了。
import com.intellij.openapi.options.Configurable;
import org.jetbrains.annotations.Nls;
import org.jetbrains.annotations.Nullable;
import top.codeease.stockwatch.component.StockSettingsComponent;
import top.codeease.stockwatch.storage.StockSettingsState;
import javax.swing.*;
/**
* @author by: 神秘的鱼仔
* @ClassName: StockConfigurable
* @Description: 股票配置的最终实现
* @Date: 2024/7/9 上午10:09
*/
public class StockConfigurable implements Configurable {
private StockSettingsComponent settingsComponent;
@Override
public @Nls(capitalization = Nls.Capitalization.Title) String getDisplayName() {
return "Stock Plugin";
}
@Override
public @Nullable JComponent createComponent() {
settingsComponent = new StockSettingsComponent();
return settingsComponent.getPanel();
}
@Override
public boolean isModified() {
StockSettingsState settings = StockSettingsState.getInstance();
return !settingsComponent.getStockSymbol().equals(settings.stockSymbol);
}
@Override
public void apply() {
StockSettingsState settings = StockSettingsState.getInstance();
settings.stockSymbol = settingsComponent.getStockSymbol();
}
@Override
public void reset() {
StockSettingsState settings = StockSettingsState.getInstance();
settingsComponent.setStockSymbol(settings.stockSymbol);
}
}
最终要将配置类注册到plugin.xml中,我们等全部介绍完后一起放进去。
# 找一个股票接口 {#找一个股票接口}
股票接口网上一找一大片,我这里找了个腾讯的接口:https://qt.gtimg.cn/q=sh000001 (opens new window)
点击后拿到的结果长下面这样,不同的数据之间用~分割
v_sh000001="1~上证指数~000001~2974.01~2971.30~2963.85~268992597~0~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~~20240715155911~2.71~0.09~2977.31~2959.13~2974.01/268992597/268733339474~268992597~26873334~0.57~13.32~~2977.31~2959.13~0.61~429130.60~566227.31~0.00~-1~-1~0.88~0~2970.27~~~~~~26873333.9474~0.0000~0~ ~ZS~-0.03~1.76~~~~3322.13~2635.09~-0.69~-1.39~-1.10~4546667906679~~-10.22~-2.77~4546667906679~~~-8.14~-0.05~~CNY~0~~0.00~0";
我将其中一些关键的参数记录了下来:
0: 未知
1: 名字
2: 代码
3: 当前价格
4: 昨收
5: 今开
6: 成交量(手)
7: 外盘
8: 内盘
29: 最近逐笔成交
30: 时间
31: 涨跌
32: 涨跌%
33: 最高
34: 最低
35: 价格/成交量(手)/成交额
36: 成交量(手)
37: 成交额(万)
38: 换手率
39: 市盈率
41: 最高
42: 最低
43: 振幅
44: 流通市值
45: 总市值
46: 市净率
47: 涨停价
48: 跌停价
自定义一个接口的返回结构,只取我想展示的内容:
/**
* @author by: 神秘的鱼仔
* @ClassName: GetStockPriceResponse
* @Description: 股票结果返回
* @Date: 2024/7/12 下午5:03
*/
@Data
public class GetStockPriceResponse {
/**
* 股票名称
*/
private String stockName;
/**
* 股票编号
*/
private String stockNo;
/**
* 当前价格
*/
private String lastTrade;
/**
* 涨跌幅
*/
private String change;
/**
* 昨收
*/
private String prevClose;
/**
* 今开
*/
private String open;
}
然后编写OkHTTP的单例实现类:
import okhttp3.OkHttpClient;
import java.util.concurrent.TimeUnit;
/**
* @author by: 神秘的鱼仔
* @ClassName: OkHttpClientSingleton
* @Description: OkHttp模块的单例实现
* @Date: 2024/7/12 上午9:52
*/
public class OkHttpClientSingleton {
private static OkHttpClient instance;
private OkHttpClientSingleton() {
// 私有构造函数,防止外部实例化
}
public static OkHttpClient getInstance() {
if (instance == null) {
synchronized (OkHttpClientSingleton.class) {
if (instance == null) {
OkHttpClient.Builder builder = new OkHttpClient.Builder();
// 设置连接超时
builder.connectTimeout(60, TimeUnit.SECONDS);
// 设置读取超时
builder.readTimeout(60, TimeUnit.SECONDS);
// 设置写入超时
builder.writeTimeout(60, TimeUnit.SECONDS);
// 构建 OkHttpClient 实例
instance = builder.build();
}
}
}
return instance;
}
}
最后编写获取数据以及处理数据的处理器:
/**
* @author by: 神秘的鱼仔
* @ClassName: StockPriceExecutor
* @Description: 股票价格
* @Date: 2024/7/12 下午2:41
*/
public class StockPriceHandler {
/**
* 腾讯的股票API接口
*/
private String STOCK_API_TX = "https://qt.gtimg.cn/q=";
public List<GetStockPriceResponse> fetchStockPrice(String stockSymbol) {
OkHttpClient client = OkHttpClientSingleton.getInstance();
String url = STOCK_API_TX + stockSymbol;
Request request = new Request.Builder()
.url(url)
.build();
String responseData = "";
List<GetStockPriceResponse> stockPriceResponseList = new ArrayList<>();
try {
Response response = client.newCall(request).execute();
responseData = response.body().string();
stockPriceResponseList = dealData(responseData);
System.out.println(responseData);
} catch (IOException e) {
e.printStackTrace();
}
return stockPriceResponseList;
}
/**
* 接口数据处理,获取到腾讯的接口后会拿到这样一串字符串,如:
* v_sh000001="1~上证指数~000001~2971.30~2970.39~2965.61~303713014~0~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~0.00~0~~20240712153511~0.91~0.03~2977.14~2963.30~2971.30/303713014/302581575979~303713014~30258158~0.65~13.27~~2977.14~2963.30~0.47~428104.13~563894.26~0.00~-1~-1~1.02~0~2970.97~~~~~~30258157.5979~0.0000~0~ ~ZS~-0.12~0.72~~~~3322.13~2635.09~0.13~-2.02~-2.82~4534435145087~~-16.75~-3.64~4534435145087~~~-8.19~0.01~~CNY~0~~0.00~0";
* 以 ~ 进行分割,一些重要的数据
* 0: 未知

* 5: 今开
* 6: 成交量(手)

*/
private List<GetStockPriceResponse> dealData(String responseData) {
List<GetStockPriceResponse> getStockPriceResponseList = new ArrayList<>();
// 如果有多个股票号,先通过;进行拆分
responseData = responseData.substring(0, responseData.length() - 1);
String[] stockArray = responseData.split(";");
for (String stockInfo : stockArray) {

# 配置Plugin.xml {#配置plugin-xml}
最后配置一下Plugin.xml,在extensions中,将需要注册的类注册进去。
<extensions defaultExtensionNs="com.intellij">
<!-- Add your extensions here -->
<applicationService serviceImplementation="top.codeease.stockwatch.storage.StockSettingsState"/>
<projectConfigurable instance="top.codeease.stockwatch.config.StockConfigurable"/>
<toolWindow id="Stock Prices" anchor="right" factoryClass="top.codeease.stockwatch.window.StockToolWindow"/>
</extensions>
这样一个股票插件就实现了。
