本文详细解析了SonarQube中sensorContext的使用原则，特别强调了DefaultHighlighting和DefaultMeasure的唯一性限制，避免重复设置导致的UnsupportedOperationException错误。通过具体代码示例，展示了如何正确应用sensorContext进行代码质量分析。

一次sonar project 扫描，sensorContext 分别会创建DefaultHighlighting（语言高亮标记设置）

和DefaultMeasure（统计测量属性），且只能设置一次。否则会报错：

Caused by: java.lang.UnsupportedOperationException: Can not add the same measure twice on src/main/resources/application-dev.properties: DefaultMeasure[component=src/main/resources/application-dev.properties,metric=Metric[id=<null>,key=ncloc,description=Non commenting lines of code,type=INT,direction=-1,domain=Size,name=Lines of Code,qualitative=false,userManaged=false,enabled=true,worstValue=<null>,bestValue=<null>,optimizedBestValue=false,hidden=false,deleteHistoricalData=false,decimalScale=<null>],value=12,fromCore=false]

再次调用了sensorContext.<T>newMeasure().withValue(value).forMetric(metric).on(inputFile).save();

 @Override
  public void leaveFile(Tree tree) {
    LinesOfCodeVisitor linesOfCodeVisitor = new LinesOfCodeVisitor(tree);
    saveMetricOnFile(CoreMetrics.NCLOC, linesOfCodeVisitor.getNumberOfLinesOfCode());

    CommentLinesVisitor commentLinesVisitor = new CommentLinesVisitor(tree);
    saveMetricOnFile(CoreMetrics.COMMENT_LINES, commentLinesVisitor.getNumberOfCommentLines());

    StatementsVisitor statementsVisitor = new StatementsVisitor(tree);
    saveMetricOnFile(CoreMetrics.STATEMENTS, statementsVisitor.getNumberOfStatements());
  }

  @SuppressWarnings({ "rawtypes", "unchecked" })
  private <T extends Serializable> void saveMetricOnFile(Metric metric, T value) {
    sensorContext.<T>newMeasure()
      .withValue(value)
      .forMetric(metric)
      .on(inputFile)
      .save();
  }

DefaultHighlighting报错：

Caused by: java.lang.UnsupportedOperationException: Trying to save highlighting twice for the 
same file is not supported: src/main/resources/application-dev.properties

再次调用了：

@Override
  public void visitFile(Tree tree) {
    highlighting = sensorContext.newHighlighting().onFile(fileSystem.inputFile(fileSystem.predicates().is(getContext().getFile())));
  }
