一、加载/显示WebView

• plugin中需要使用JCEF加载webView

// 创建 JBCefBrowser
        JBCefBrowser jbCefBrowser = new JBCefBrowser();
        // 将 JBCefBrowser 的UI控件设置到Panel中
        this.content.add(jbCefBrowser.getComponent(), BorderLayout.CENTER);
        // 加载URL
        jbCefBrowser.loadURL(YOUR_URL);

• 注意点：
  • 需要使用JetBrains的JDK, 参考：https://plugins.jetbrains.com/docs/intellij/ide-development-instance.html#using-a-jetbrains-runtime-for-the-development-instance

js 向 java通信

• 1. 在H5中添加以下js:

 <script type="text/javascript">
     function callJava(arg) {
        ;
     }
 </script>

• 通过 JBCefJSQuery 拦截、接收js侧callJava方法，参考代码：

        JBCefJSQuery query = JBCefJSQuery.create((JBCefBrowserBase) browser);
        query.addHandler((String arg) -> {
            try {
                JSONObject requestAsJson = JSON.parseObject(arg);
                System.out.println("in Handler fast json" + requestAsJson.toJSONString());
                return new JBCefJSQuery.Response("msg");
            } catch (Exception e) {
                return new JBCefJSQuery.Response(null, 0, "errorMsg");
            }
        });

        browser.getJBCefClient().addLoadHandler(new CefLoadHandler() {
            @Override
            public void onLoadingStateChange(CefBrowser cefBrowser, boolean isLoading, boolean canGoBack, boolean canGoForward) {
            }

            @Override
            public void onLoadStart(CefBrowser cefBrowser, CefFrame frame, CefRequest.TransitionType transitionType) {
            }

            @Override
            public void onLoadEnd(CefBrowser cefBrowser, CefFrame frame, int httpStatusCode) {
                System.out.println("onLoadEnd");
                cefBrowser.executeJavaScript(
                        "window.callJava = function(arg) {" +
                                query.inject(
                                        "arg",
                                        "response => console.log('callJava 成功', response)",
                                        "(error_code, error_message) => console.log('callJava 失败', error_code, error_message)"
                                ) +
                                "};",
                        null, 0);
            }

            @Override
            public void onLoadError(CefBrowser cefBrowser, CefFrame frame, ErrorCode errorCode, String errorText, String failedUrl) {
            }
        }, browser.getCefBrowser());
    }
