Kafka Connect连接器的全生命周期：

以下是基于Vue和PySide2的两种图形化界面设计方案，用于管理Kafka Connect连接器的全生命周期：

方案一：Vue3 Web管理平台

技术栈

- 前端：Vue3 + Element Plus + ECharts
- 通信：Axios + WebSocket
- 安全：JWT + HTTPS
- 打包：Vite + Docker

核心功能模块

<!-- 连接器配置向导组件 -->
<template>
  <el-steps direction="vertical">
    <!-- 步骤1：选择连接器类型 -->
    <el-step title="连接器类型">
      <el-radio-group v-model="connectorType">
        <el-radio label="source">MySQL Source</el-radio>
        <el-radio label="sink">JDBC Sink</el-radio>
      </el-radio-group>
    </el-step>

    <!-- 步骤2：数据库配置 -->
    <el-step title="数据库配置">
      <el-form :model="dbConfig" label-width="120px">
        <el-form-item label="主机地址" required>
          <el-input v-model="dbConfig.host"></el-input>
        </el-form-item>
        <el-form-item label="端口">
          <el-input-number v-model="dbConfig.port"></el-input-number>
        </el-form-item>
        <el-form-item label="用户名">
          <el-input v-model="dbConfig.user"></el-input>
        </el-form-item>
        <el-form-item label="密码">
          <el-input type="password" show-password></el-input>
        </el-form-item>
      </el-form>
    </el-step>

    <!-- 步骤3：高级配置 -->
    <el-step title="高级配置">
      <el-collapse>
        <el-collapse-item title="数据过滤">
          <el-input 
            v-model="filters.includeTables"
            placeholder="包含的表 (逗号分隔)">
          </el-input>
        </el-collapse-item>
        <el-collapse-item title="性能参数">
          <el-input-number 
            v-model="performance.batchSize" 
            label="批量大小">
          </el-input-number>
        </el-collapse-item>
      </el-collapse>
    </el-step>
  </el-steps>
</template>

监控面板设计

<!-- 实时监控仪表盘 -->
<template>
  <el-row :gutter="20">
    <el-col :span="8">
      <el-card>
        <template #header>
          <span>吞吐量监控</span>
        </template>
        <echarts :option="throughputChartOpt"/>
      </el-card>
    </el-col>
    
    <el-col :span="16">
      <el-card>
        <template #header>
          <span>连接器状态矩阵</span>
        </template>
        <el-table :data="connectorStatus">
          <el-table-column prop="name" label="名称"/>
          <el-table-column label="状态">
            <template #default="{row}">
              <el-tag :type="statusColor(row.state)">
                {
  { row.state }}
              </el-tag>
            </template>
          </el-table-column>
          <el-table-column label="操作">
            <template #default="{row}">
              <el-button-group>
                <el-button @click="pauseConnector(row.name)">暂停</el-button>
                <el-button @click="showLogs(row.name)">日志</el-button>
              </el-button-group>
            </template>
          </el-table-column>
        </el-table>
      </el-card>
    </el-col>
  </el-row>
</template>

API交互层

// Kafka Connect API服务封装
import axios from 'axios'

const connectAPI = axios.create({
   
  baseURL: '/api/connect',
  timeout: 10000
})

// 连接器操作类
class ConnectorManager {
   
  static async createConnector(config) {
   
    const resp = await connectAPI.post('/connectors', {
   
      name: config.name,
      config: this._buildConfig(config)
    })
    return resp.data
  }

  static _buildConfig(rawConfig) {
   
    // 配置转换逻辑
    return {
   
      "connector.class": rawConfig.type === 'source' ? 
        'io.debezium.connector.mysql.MySqlConnector' :
        'io.confluent.connect.jdbc.JdbcSinkConnector',
      "database.hostname": rawConfig.host,
      "connection.url": `jdbc:mysql://${
     rawConfig.host}:${
     rawConfig.port}/${
     rawConfig.database}`,
      // 其他参数映射...
    }
  }
}

方案二：PySide2桌面客户端

界面布局设计

# 主窗口类
class ConnectManagerWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        
        # 连接器列表
        self.connector_list = QTableWidget()
        self.connector_list.setColumnCount(4)
        self.connector_list.setHorizontalHeaderLabels(
            ["名称", "类型", "状态", "操作"]
        )
        
        # 配置表单
        self.config_form = QTabWidget()
        self.source_tab = SourceConfigTab()
        self.sink_tab = SinkConfigTab()
        self.config_form.addTab(self.source_tab, "MySQL Source")
        self.config_form.addTab(self.sink_tab<
