如何在catch语句中获得适当的错误？

try {
    // 可能引发错误的代码
} catch (Exception e) {
    String errorMessage = e.getMessage();
    // 处理错误
}

try {
    // 可能引发错误的代码
} catch (Exception e) {
    e.printStackTrace();
    // 处理错误
}

import com.tencentcloudapi.monitor.v20180724.MonitorClient;
import com.tencentcloudapi.monitor.v20180724.models.PutMonitorDataRequest;
import com.tencentcloudapi.monitor.v20180724.models.PutMonitorDataResponse;

try {
    // 可能引发错误的代码
} catch (Exception e) {
    String errorMessage = e.getMessage();
    e.printStackTrace();
    
    // 使用腾讯云的云监控服务发送错误信息
    MonitorClient client = new MonitorClient(credentials, region);
    PutMonitorDataRequest request = new PutMonitorDataRequest();
    request.setNamespace("your_namespace");
    request.setMetricName("your_metric_name");
    request.setValue(1.0);
    request.setDimensions(new ArrayList<Dimension>());
    request.setTimestamp(System.currentTimeMillis() / 1000L);
    
    try {
        PutMonitorDataResponse response = client.PutMonitorData(request);
        // 处理响应
    } catch (Exception ex) {
        // 处理异常
    }
}
