java中springboot怎么集成kettle

在Java中,集成Kettle有多种方法,其中一种是使用Spring Boot框架。下面是一些基本步骤:
1. 在pom.xml中添加以下依赖项:
```
<dependency>
<groupId>org.pentaho</groupId>
<artifactId>kettle-core</artifactId>
<version>8.3.0.0-371</version>
</dependency>
<dependency>
<groupId>org.pentaho</groupId>
<artifactId>kettle-engine</artifactId>
<version>8.3.0.0-371</version>
</dependency>
```
2. 创建一个KettleService类,该类将提供与Kettle的交互方法,例如:
```
@Service
public class KettleService {
public void runTransformation(String transformationPath) throws KettleException {
KettleEnvironment.init();
TransMeta transMeta = new TransMeta(transformationPath);
Trans trans = new Trans(transMeta);
trans.execute(null);
trans.waitUntilFinished();
if (trans.getErrors() > 0) {
throw new KettleException("There are errors during transformation execution.");
}
}
}
```
3. 在应用程序中使用KettleService类来运行转换。例如,可以在控制器类中注入该类并调用该类的方法:
```
@RestController
@RequestMapping("/api")
public class MyController {
@Autowired
private KettleService kettleService;
@PostMapping("/run-transformation")
public ResponseEntity<Void> runTransformation(@RequestParam("path") String path) throws KettleException {
kettleService.runTransformation(path);
return ResponseEntity.ok().build();
}
}
```
这是一个基本的集成Kettle和Spring Boot的示例,你可以根据自己的需求进行修改和扩展。
