java - log4J is Not Writing to Specific Log File in Spring Boot Microservice -


am trying use log4j write local log file in filesystem.

actually used exact properties file different project , changed name of top level directory match app's name. different project writes logs.log file doesn't print content @ all. both projects use same version of log4j.

pom.xml

<dependency>    <groupid>log4j</groupid>    <artifactid>log4j</artifactid>    <version>1.2.17</version> </dependency>

on unix based macos, cd'ed /var/log/ , did following:

sudo mkdir myapp chmod 777 myapp

have inside myapp, following setup on place:

if (log.isdebugenabled() {    log.debug("print something"); }

myapp/src/main/resources/log4j.properties:

log4j.rootcategory=debug, rf  log4j.category.your.category.name=debug  log4j.appender.stdout=org.apache.log4j.consoleappender log4j.appender.stdout.layout=org.apache.log4j.patternlayout  log4j.appender.stdout.layout.conversionpattern=%-5p [%f]: %m [%d{iso8601}]%n log4j.logger.com.amazonaws=debug rf  log4j.appender.rf=org.apache.log4j.rollingfileappender log4j.appender.rf.file=/var/log/myapp/logs.log  log4j.appender.rf.maxfilesize=10mb log4j.appender.rf.maxbackupindex=30 log4j.appender.rf.layout=org.apache.log4j.patternlayout log4j.appender.rf.layout.conversionpattern=[%d{iso8601}]%5p%6.6r[%t]%x(%f:%l) - %m%n threshold=debug

don't understand why inside:

/var/log/myapp/

there's no logs.log file present!

am using inside spring boot 1.5.4.release build using:

mvn clean install

and run using either:

java -jar myapp.jar

or

mvn spring-boot:run

would appreciate if provide me either better properties file or see doing wrong?

thank taking time read this.

@veeram right - logs printed logback, comes along spring boot. need replace log4j. however, not option:

from spring boot 1.4.0 release notes:

log4j 1 support has been removed following apache eol announcement.

so may suggest consider upgrade log4j 2.

p.s. think still can use log4j 1.2, in case, have define , specify dependencies should excluded spring-boot-starter-logging module, , should added instead. i've set demo project reproduce problem , here list of dependencies in build.gradle (i use gradle, think point):

dependencies {     compile('org.springframework.boot:spring-boot-starter') {         exclude group: 'ch.qos.logback'         exclude group: 'org.slf4j', module: 'log4j-over-slf4j'     }     compile('commons-logging:commons-logging:1.2')     compile('log4j:log4j:1.2.17')     compile('org.slf4j:slf4j-log4j12:1.7.25')     testcompile('org.springframework.boot:spring-boot-starter-test') }

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
