在grails 3的bootstrap.groovy中添加文件？

Question

我想在grails 3.3.9版本的bootstrap.groovy文件中添加一个文件。 在bootstrap.groovy中：

Route::group(['prefix' => 'api/v1'], function () { 

    \Log::info('step 1');

    Route::middleware('auth:api')->group(function () {

        \Log::info('step 2');
        Route::get('/products','APIController@getProducts');
        Route::get('/logout','PassportController@logout')->name('logout');

    });

});

执行run-app时，出现以下错误

package com.nuevaconsulting
import com.nuevaconsulting.embrow.*

class BootStrap {
def init = { servletContext ->

        def filePath = "C:/Grails/embrow/grails-app/conf/resourcesresources/1.csv"
        new File(filePath).splitEachLine(',') 
        {
        fields ->
def employee = new Employee(
    mirId: fields[0].trim(),
   cancer : fields[1].trim(),
    profile : fields[1].trim(),
     pubmed : fields[1].trim()      
)

if ( employee.hasErrors() ||  employee.save(flush: true) == null) {
    log.error("Could not import  employee  ${ employee.errors}")
}

log.debug("Importing  employee  ${ employee.toString()}")
}
def destroy = {}}}

如何添加和可视化？
