import com.tableausoftware.TableauException;

public class TestTableau {

    public static void main(String[] args) throws IOException {
        //delete existing extract file
        String extractFile = "extract.tde";
        deleteFile(extractFile);

        try (Extract extract = new Extract(extractFile)) {
            //create table definition
            TableDefinition tableDef = new TableDefinition();
            int columnCount = 100;
            for (int i = 0; i < columnCount; i++) {
                tableDef.addColumn(Integer.toString(i), Type.UNICODE_STRING);
            }

            //create a table
            Table table = extract.addTable("Extract", tableDef);

            //create a sample document
            //reuse the document for each row to minimize the non-tableau CPU and memory consumption
            Random random = new Random();
            List<String> rowData = new ArrayList<>();
            for (int i = 0; i < columnCount; i++) {
                rowData.add(Integer.toString(random.nextInt()));
            }

            long startTime = System.nanoTime();
            System.out.println("Populating table...");

            //populate the table
            int tableRows = 4000000;
            for (int i = 0; i < tableRows; i++) {
                //convert input document to tableau row
                Row row = new Row(tableDef);
                for (int j = 0; j < rowData.size(); j++) {
                    row.setString(j, rowData.get(j));
                }

                //add the row to the table
                table.insert(row);
            }

            long endTime = System.nanoTime();
            System.out.println(String.format("Total time (ms): %s", (endTime - startTime) /
                    1000000));

        } catch (TableauException e) {
            e.printStackTrace();
        }
    }

    private static void deleteFile(String file) {
        File extractFile = new File(file);
        if (extractFile.exists()) {
            extractFile.delete();
        }
    }
}

当我运行代码时出现异常:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'TableauExtract': The specified module could not be found.

at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:194) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:283) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:244) at com.sun.jna.Native.register(Native.java:1065) at com.tableausoftware.extract.Extract.(Unknown Source) at TestTableau.main(TestTableau.java:21)

我已将以下 jar 文件添加到构建路径:

tableauextract.jar jna.jar tableaucommon.jar

如何解决这个问题？

Answer 1

如果您已将库添加到构建路径中，您是否尝试再次清理并构建项目？
