I'm trying to access the Pylons configuration from inside a repoze.who "authenticator".. I'm using from pylons import config, but it looks like it returns a configuration with default values, not the ones from production.ini.. What am I missing?
You must using pylons.config after calling load_environment(global_conf, app_conf) in config/middleware.py or use direct app_conf
Found a thread that suggests two options:
Passing the config directly to the authenticator instance during middleware setup
Adding a pylons.config.update(config) at the bottom of load_environment

I want to get access to external YAML file which I specify through command-line argument:
java -jar target/app-thorntail.jar -s./test.yaml
This file I need to use to get my custom properties tree by SnakeYaml.
You can use #Inject #ConfigurationValue for your custom properties, and you can #Inject a ConfigView to read the entire configuration tree. I believe that should be enough for your usecase. This approach will also provide correct values in case multiple configuration files are used.
I'm not sure if you can get access to the file itself, except maybe provide a custom main method and parse the command-line arguments yourself.
I am trying to use Spring Cloud Config Server to externalize my Grails 3 (personnel) application configuration, but I cannot seem to set the dataSource properties.
Currently, I can load other properties (sample.message) into my Grails 3 (personnel) application and retrieve them using grailsApplication.config.sample.message without an issue. And hitting the REST endpoint on the Config Server (localhost:8888/personnel/master) is showing the configuration information I want, so I'm a bit confused.
I have tried each of the following in my personnel.properties file in my Git repo:
datasource.user=example
datasource.password=example
grails.datasource.user=example
grails.datasource.password=example
spring.datasource.user=example
spring.datasource.password=example
But none of them work. I continue to see error messages saying sa#localhost (using password: no) suggesting that the datasource properties, in particular, are not working.
I know it is possible with spring-boot-starter-data-jpa, so I'm wondering:
Is it possible with GORM?
If so, do I need to manually create the datasource bean?
What property names do I use datasource.user, grails.datasource.user, spring.datasource.user, etc?
After Shashank's edit, I realized that it was an issue with my property settings. datasource should have been dataSource and user should be username. Once those corrections were made, the application (personnel) worked perfectly. So,
Yes it is possible.
No, you don't need to create the bean manually
Property names are:
personnel.properties
dataSource.username=example
dataSource.password=example
dataSource.url=jdbc:mysql://localhost:3306/personnel
Is it possible to customize Dropwizrd's healthcheck output so that, e.g.: /health for healthchecks instead of /healthcheck and some output like {“status”: 200}.
I realise I could simply write a new resource that does what ever I need, I was just wondering if there is a more standard way to do this.
From what I have read on the 0.7.1 source code it's not possible to change the resource URI for healthchecks unfortunately, I highly doubt you can change the healthcheck format. I also remember people complaining about not being able to add REST resources to admin page, only servlets. Maybe on 0.8.0?
Here are the details of what I've tracked so far on the source code. Maybe I have misread or misunderstood something, so somebody could fix it.
Metrics has actually written AdminServlet to add healtcheck servlet in a way that it checks the servlet config whether the URI is defined or not.
this.healthcheckUri = getParam(config.getInitParameter(HEALTHCHECK_URI_PARAM_KEY), DEFAULT_HEALTHCHECK_URI);
But dropwizard doesn't provide a way to inject this configuration in any way on AbstractServerFactory.
handler.addServlet(new NonblockingServletHolder(new AdminServlet()), "/*");
NonblockingServletHolder is the one which is providing the config to AdminServlet but is created by AbstractServerFactory with empty constructor and provides no way to change the config.
I've thought of and tried to access the ServletHolder from the Environment object on Application.run method but the admin servlets are not created until after run method is run.
environment.getAdminContext().getServletHandler().getServlets()[0].setInitParameter("healthcheck-uri", "/health");
Something like this in your run() function will help you control the URI of your healthchecks:
environment.servlets().addServlet(
"HealthCheckServlet",
new HealthCheckServlet(environment.healthChecks())
).addMapping("/health");
If you want to actually control what's returned you need to write your own resource file. Fetch all the healthchecks from the registery, run them and return whatever aggregated value you want based on their results.
As described in Can't call one closure from another, I am using a pluggable script from within a Grails app.
Unfortunately, I've found that I can't use log4j from within these scripts. I am forced to use println.
I tried using
import org.apache.commons.logging.LogFactory
def Log log = LogFactory.getLog(getClass())
but I got no output. When I print out the result of the call to getClass(), I get something like
myscript$_run_closure5
So I'm thinking the issue is that there is no configuration in my Grails Config.groovy file for this class.
Is there a way for me to programmatically add these pluggable scripts to the log4j configuration? Keep in mind that I do not know in advance what the names of the scripts are, so this has to happen at runtime.
Consider the following code:
import org.apache.log4j.Logger
// ...
Logger log = Logger.getLogger('MyPlugin')
new File( grailsApplication.config.externalFiles ).eachFile { file ->
Binding binding = new Binding()
binding.variables.log = log
GroovyShell shell = new GroovyShell(binding)
shell.evaluate(file)
strategies.put( binding.variables.key, binding.variables )
}
Explanation:
It is not obligatory to pass class name to getLogger, it can be actually any string. You just need to make sure that this string is matched in log4j.properties of the main program.
You pass once created log to plugin scripts via binding variable "log". Then plugin scripts can access it simply as log.info('test123')
My personal recommendation would be to use logback instead of log4j. Both libraries were developed by the same guy and it is stated that logback supersedes log4j.
I am trying to use an ini file to login into a grails application with the shiro plugin. I have created an ini file and put it in the config folder. The ini is displayed below.
[main]
[users]
admin=heslo, Administrator
[roles]
Administrator = *
[urls]
I created a service with the method createSecurityManager() which I call at bootstrap:
def createSecurityManager() {
Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
SecurityManager securityManager = factory.getInstance();
println securityManager
SecurityUtils.setSecurityManager(securityManager);
securityManager
}
When I try logging in using the username admin and password heslo, the login fails.
have you tried the quick-start described in the plugin documentaion?
http://grails.org/plugin/shiro
In order to use an ini-file, I guess you have to create your own realm.
When using the grails shiro plugin, I think the easiest way to use it is to create the standard DB-Realm and initialize it in the bootstrap - the same way the quick-start describes it :-)
But the Shiro CAS configuration should be done using the ini file approach right?
I've been referring to this link: http://shiro.apache.org/cas.html
Is there a way to configure CAS authentication with the quick-start approach that comes without an ini config?
