3、springboot 整合 kettle

一、加載jar包到項目

kettle-core-7.0.0.0-25.jar

kettle-engine-7.0.0.0-25.jar

metastore-7.0.0.0-25.jar

 

以上三個 jar 包在 kettle 下的 lib 目錄下，將其放進項目的 lib 目錄下，執行maven命令引入項目：

mvn install:install-file -Dfile=/data/apps/studyP/kettleDemo/lib/kettle-core-7.0.0.0-25.jar  -DgroupId=pentaho-kettle -DartifactId=kettle-core -Dversion=7.0.0.0-25 -Dpackaging=jar
mvn install:install-file -Dfile=/data/apps/studyP/kettleDemo/lib/kettle-engine-7.0.0.0-25.jar  -DgroupId=pentaho-kettle -DartifactId=kettle-engine -Dversion=7.0.0.0-25 -Dpackaging=jar
mvn install:install-file -Dfile=/data/apps/studyP/kettleDemo/lib/metastore-7.0.0.0-25.jar  -DgroupId=pentaho-kettle -DartifactId=metastore -Dversion=7.0.0.0-25 -Dpackaging=jar

• 執行kettle 腳本代碼

@Test
public void test() throws KettleException {
    // 初始化
    KettleEnvironment.init();


    // 加載文件
    TransMeta transMeta = new TransMeta("C:\\Users\\lenovo\\Desktop\\klg_test_qy.ktr");
    Trans trans = new Trans(transMeta);


    // 放入參數，這裏其實可以從數據庫中取到，如果沒有參數，可以把這步忽略
    // trans.setParameterValue("stade", "2019-04-24");
    trans.prepareExecution(null);
    trans.startThreads();
    trans.waitUntilFinished();
}
