-
in springboot project work on there transitive maven dependency on spring-data-mongodb. therefore mongohealthindicator seems activated automatically although project not use mongodb. possible deactivate healthindicator without deactivating actuator health endpoint? workaround found excluding dependency. wondering if possible specific deactivation of mongohealthindicator. from: http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html # health indicators (previously health.*) ... management.health.mongo.enabled=true ... you should able set false disable health indicator. org.springframework.boot.actuate.autoconfigure.healthindicatorautoconfiguration.java @configuration @conditionalonbean(mongotemplate.class) @conditionalonproperty(prefix = "management.health.mongo", name = "enabled", matchifmissing = true) public static class mongohealthindicatorconfiguration {

javascript - How to promisify Node's child_process.exec and child_process.execFile functions with Bluebird? -

-
i'm using bluebird promise library under node.js, it's great! have question: if take @ documentation of node's child_process.exec , child_process.execfile can see both of these functions returning childprocess object. so what's recommended way promisify such functions? note following works (i promise object): var promise = require('bluebird'); var execasync = promise.promisify(require('child_process').exec); var execfileasync = promise.promisify(require('child_process').execfile); but how can 1 access original return value of original node.js functions? (in these cases need able access returned childprocess objects.) any suggestion appreciated! edit: here example code using return value of child_process.exec function: var exec = require('child_process').exec; var child = exec('node ./commands/server.js'); child.stdout.on('data', function(data) { console.log('stdout: ' + data); }); child.
