3、springboot 整合 kettle

一、加载jar包到项目

kettle-core-7.0.0.0-25.jar

kettle-engine-7.0.0.0-25.jar

metastore-7.0.0.0-25.jar

 

以上三个 jar 包在 kettle 下的 lib 目录下，将其放进项目的 lib 目录下，执行maven命令引入项目：

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

 

• 引入依赖

<!-- 集成kettle -->

• 执行kettle 脚本代码

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


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


    // 放入参数，这里其实可以从数据库中取到，如果没有参数，可以把这步忽略
    // trans.setParameterValue("stade", "2019-04-24");
    trans.prepareExecution(null);
    trans.startThreads();
    trans.waitUntilFinished();
}
