java - IBM Watson 音调分析器

Question

试图使示例代码工作。我正在使用 Java 7。

我在这条线上得到一个错误

service.setUsernameAndPassword("<username>", "<password>");

该通知要求我在存储库中搜索“服务”。这不应该是这种情况，因为服务是在上面的行中定义的。有谁知道这里可能出了什么问题？

import com.ibm.watson.developer_cloud.tone_analyzer.v3.*;
import com.ibm.watson.developer_cloud.tone_analyzer.v3.model.ToneAnalysis;
import com.ibm.watson.developer_cloud.tone_analyzer.v3.model.ToneOptions;

public class test {

    ToneAnalyzer service = new ToneAnalyzer("2017-09-21");
service.setUsernameAndPassword("<username>", "<password>");

String text =
  "I know the times are difficult! Our sales have been "
      + "disappointing for the past three quarters for our data analytics "
      + "product suite. We have a competitive data analytics product "
      + "suite in the industry. But we need to do our job selling it! "
      + "We need to acknowledge and fix our sales challenges. "
      + "We can’t blame the economy for our lack of execution! "
      + "We are missing critical sales opportunities. "
      + "Our product is in no way inferior to the competitor products. "
      + "Our clients are hungry for analytical tools to improve their "
      + "business outcomes. Economy has nothing to do with it.";

// Call the service and get the tone
ToneOptions toneOptions = new ToneOptions.Builder()
  .html(text)
  .build();

ToneAnalysis tone = service.tone(toneOptions).execute();
System.out.println(tone);

}

我还收到 System.out.println 的错误，说它找不到符号“音调”。

pom文件：

    <dependency>
        <groupId>com.ibm.watson.developer_cloud</groupId>
        <artifactId>java-sdk</artifactId>
        <version>6.1.0</version>
    </dependency>

Answer 1

service.setUsernameAndPassword("<username>", "<password>");

这是一个调用语句，应该在一个方法中。

可能你想像这样重写你的类：

import com.ibm.watson.developer_cloud.tone_analyzer.v3.*;
import com.ibm.watson.developer_cloud.tone_analyzer.v3.model.ToneAnalysis;
import com.ibm.watson.developer_cloud.tone_analyzer.v3.model.ToneOptions;

public class Test {

public static void main(String...s) {
    ToneAnalyzer service = new ToneAnalyzer("2017-09-21");
service.setUsernameAndPassword("<username>", "<password>");

String text =
  "I know the times are difficult! Our sales have been "
      + "disappointing for the past three quarters for our data analytics "
      + "product suite. We have a competitive data analytics product "
      + "suite in the industry. But we need to do our job selling it! "
      + "We need to acknowledge and fix our sales challenges. "
      + "We can’t blame the economy for our lack of execution! "
      + "We are missing critical sales opportunities. "
      + "Our product is in no way inferior to the competitor products. "
      + "Our clients are hungry for analytical tools to improve their "
      + "business outcomes. Economy has nothing to do with it.";

// Call the service and get the tone
ToneOptions toneOptions = new ToneOptions.Builder()
  .html(text)
  .build();

ToneAnalysis tone = service.tone(toneOptions).execute();
System.out.println(tone);

}

}

PS：以大写字母开头的类名是一个很好的编码标准。
