Spring Boot - Gradle Exclusions Not Reflecting in Gradle Cache - spring

I spent way too much time on this, I am trying to use log4j instead of spring boot logging, Unfortuantley every time i start my sprint boot app i use to get slf4j binding error as below .
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/doddmani/.gradle/caches/modules-2/files-2.1/ch.qos.logback/logback-classic/1.1.11/ccedfbacef4a6515d2983e3f89ed753d5d4fb665/logback-classic-1.1.11.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/doddmani/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-slf4j-impl/2.8.2/36bc2a99b86be26ccdc51fe288458dc712d280c1/log4j-slf4j-impl-2.8.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
2017-11-21 15:29:51.004 INFO 9692 --- [ restartedMain] o.apache.catalina.core.StandardService : Starting service Tomcat

And I did see there was a dependency in logback.jar when i executed gradle dependency command. I fixed it by adding exclusions in my gradle file as below.
configurations {
all*.exclude module : 'logback-classic'
}
With this fix, i see no more refenrence to logback jars in dependency list, But everytime i run my app again , Its still fetching reference from gradle cache and continues to say SLF4J Binding exceptions. Can any one pls help me getting this issue sorted out.

I've had similar problem. I was trying add log4j2 to my spring boot app, this config fix it to me
configurations.all {
all*.exclude module: 'slf4j-log4j12'
all*.exclude module : 'logback-classic'
}

How to add default logback.xml to spring boot project?

I have created a new spring boot project using spring initializer with spring-boot-starter-web as a starter project.I am able to use logback for logging but am unable to find default logback.xml in the project.I tried to search out but could not find reference to default file on logback documentation as well. I am looking to customize the logback file to use custom appender.
You can customize by using your application.yml, like this :
logging:
level:
root: WARN
org.springframework.security: DEBUG
org.springframework.web.servlet: INFO
org.springframework.jmx: INFO
org.springframework.cloud.config.client: INFO
org.springframework.cloud.context: INFO
org.hibernate: INFO
org.hibernate.sql: DEBUG
pattern:
console: '%date{HH:mm:ss.SSS} [%-5level] %-65logger - %msg%n'
file: '%date{HH:mm:ss.SSS} [%-5level] %-65logger - %msg%n'
file: D:/logs/my-log.log
And define for each profile

Grails 4 - Google Cloud Platform deployment keeps restarting

My Grails 4 application, deployed to GCP appears to be trying to start up after being deployed but never comes up properly. Application requests return a 500 response. There are no errors or clues with DEBUG log level output at the root level.
The same application runs fine locally in development mode.
The production configuration is as per the Grails 3 deployment (to GCP) guide except for the adjustments that were necessary to make it work for Grails 4/Java 11.
Most of the bootstrapping appears to carry out as expected;
Spring Security configures successfully
Spring Security REST configures successfully
Spring beans are registered
Connects to Cloud SQL instance
Database schema is created (by Liquibase)
Plugins are loaded successfully
Then it gets to the following familiar lines of output logging;
INFO --- [main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 8080 (http)
INFO --- [main] o.a.coyote.http11.Http11NioProtocol : Initializing ProtocolHandler ["http-nio-8080"]
INFO --- [main] o.apache.catalina.core.StandardService : Starting service [Tomcat]
INFO --- [main] org.apache.catalina.core.StandardEngine : Starting Servlet engine: [Apache Tomcat/9.0.17]
and restarts..
while normally, the next phase of bootstrapping (happens locally) would be;
[restartedMain] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring embedded WebApplicationContext
[restartedMain] o.s.web.context.ContextLoader : Root WebApplicationContext: initialization completed in 42018 ms
Probably a long shot question but any level of clues or suggestions would be much appreciated.
I've run out of doors to open. :-(
You could try to update Tomcat version just in case.
But looking at Grails documentation:
https://docs.grails.org/latest/guide/upgrading.html
There's some configuration made when you upgrade to Grails 4 from
Grails 3.3.x to prevents the server from restarting when views or
message bundles are changed.
Either modifying a gsp in Grails 4 M2 cause the application to restart.

Problem with Google Cloud Pub/Sub API and Spring boot application

I write spring boot application for subscribing Google cloud Pub/Sub topic for this I use Google's tutorial, but when I run application I have get this error
2019-02-02 18:03:10.248 INFO 15080 --- [ main] o.apache.catalina.core.StandardService : Stopping service [Tomcat]

***************************
Description:
Parameter 1 of method messageChannelAdapter in tech.garoon.cloud.CloudApplication required a bean of type 'org.springframework.cloud.gcp.pubsub.core.PubSubTemplate' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.cloud.gcp.pubsub.core.PubSubTemplate' in your configuration.
Process finished with exit code 1
How Can I solve this problem?
GcpPubSubAutoConfiguration provides autoconfiguration feature of creating necessary beans including PubSubTemplate. In your case, somethng is missed, Kindly ensure that dependencies are in place or recreate following bean to make it work.
#Bean
public PubSubTemplate pubSubTemplate(PubSubPublisherTemplate pubSubPublisherTemplate,
PubSubSubscriberTemplate pubSubSubscriberTemplate) {
return new PubSubTemplate(pubSubPublisherTemplate, pubSubSubscriberTemplate);
}
Additionally, make sure GcpContextAutoConfiguration is created based on below properties in application.properties.
spring.cloud.gcp.credentials.location=${gcp_credentials}
starter dependency:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-starter-pubsub</artifactId>
</dependency>
Solution
I added this dependency
implementation 'org.springframework.cloud:spring-cloud-gcp-autoconfigure:1.1.0.RELEASE'
My dependencies
dependencies {
implementation 'org.springframework.cloud:spring-cloud-gcp-pubsub:1.1.0.RELEASE'
implementation 'org.springframework.cloud:spring-cloud-gcp-autoconfigure:1.1.0.RELEASE'
implementation "org.springframework.boot:spring-boot-starter-web:2.1.2.RELEASE"
implementation 'org.springframework.integration:spring-integration-core:5.1.2.RELEASE'
}
if using external configuration class that is registering your channels, message handlers etc, make sure to annotate the configuration class with #Import({GcpPubSubAutoConfiguration.class})
#Configuration
#Import({GcpPubSubAutoConfiguration.class})
public class PubSubConfig{
}
I ran into this issue with these versions of spring-boot and spring-cloud-gcp-starter-pub:
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-starter-pubsub</artifactId>
<version>1.2.8.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<version>1.2.8.RELEASE</version>
</dependency>
and in my application.properties I had
spring.cloud.gcp.pubsub.enabled=false for local development.
I removed spring.cloud.gcp.pubsub.enabled=false and it worked. Although now it creates a connection to the pubsub gcp topic, so for local development, you will need to comment out publishing, to avoid sending messages.

Spring Boot Does Not Seem to Start

I am trying to get a Spring Boot WAR to deploy to a private Tomcat 7.0.68 instance hosted by DailyRazor. I cannot figure out why the Spring Boot application will not work. I do not seem to get any errors. Locally, I have gotten this to work with STS 3.8.4, Tomcat 7.0.78, Tomcat 8.5.11, and a couple other versions of Tomcat.
I never see the Spring Boot banner display on the DailyRazor instance nor much of the other logging indicating that my Spring Boot application is starting and loading all of the beans. This is the only logging I see:

I have following the instructions for packaging as a WAR, extending SpringBootServletInitializer, overriding configure(...), etc. Again, this all works locally on multiple versions of Tomcat. I have tried to adjust the logging, but I do not see anything useful.
Any hints? Suggestions?
EDIT
Not sure if it is related, but when shutting down Tomcat, I see the following:

Could you please ensure you did all of this correctly ?
From Create a deployable war file (Spring boot documentation) :
Create a deployable war file
The first step in producing a deployable war file is to provide a
SpringBootServletInitializer subclass and override its configure
method. This makes use of Spring Framework’s Servlet 3.0 support and
allows you to configure your application when it’s launched by the
servlet container. Typically, you update your application’s main class
to extend SpringBootServletInitializer:
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
The next step is to update your build configuration so that your
project produces a war file rather than a jar file. If you’re using
Maven and using spring-boot-starter-parent (which configures Maven’s
war plugin for you) all you need to do is to modify pom.xml to
change the packaging to war:
<packaging>war</packaging>
EDIT
Do you have spring-boot-starter-web and spring-boot-starter-tomcat dependencies ?
To build a war file that is both executable and deployable into an
external container you need to mark the embedded container
dependencies as “provided”, e.g:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Spring Boot 1.4 not loading application.properties after upgrade

I am in process of upgrading a spring boot 1.3.3 project to 1.4.2.
After upgrading the project Spring boot will no longer use any application.properties file. It does not locate it. Even when passed as an startup argument.
The project is built with gradle and a shadowjar plugin to compile to a fat jar and start tomcat embedded from the jar.
The way the application is started is: java -jar app-all.jar. The directory containing the jar also contains the application.properties file. (and no other files)
There is no classpath set and the jar file does not contain any other application.properties files. (Tested with unzip -t app-all.jar |grep application.properties)
Starting the project under Spring Boot 1.3.3. The application starts correctly. Start of log file:
04:15:58.846 com.app.MaxApplication INFO [main] - Starting MaxApplication on test-ng with PID 30096 (/home/ubuntu/app-all.jar started by ubuntu in /home/ubuntu)

04:15:58.947 org.springframework.boot.context.config.ConfigFileApplicationListener DEBUG [main] - Loaded config file 'file:./application.properties'
Changing spring boot version to 1.4.2, cleaning gradle caches and rebuilding and running the application the same way Spring Boot does nto load the applciation.properties file and the application fails to start due to missing configuration settings provided by the file. Start of log file:

Only two files in the current directory are the application.properties file and the jar file. The externalizing configration documentation says the configuration should be read from there. It also works under Spring 1.3.3
I have defined a configuration class (this is working in 1.3)
#Component
#Configuration
#SpringBootConfiguration
public class MaxApplicationProperties {
#Bean
public static PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
I have tried:
Adding application.properties file to the class path.
Starting the application with --spring.config.location=application.properties (and with full path as well)
Setting config location environment variables.
Adding annotation #PropertySource("classpath:application.properties") to the MaxApplicationProperties class
Force deleting all downloaded libraries and having gradle re-download everything.
None of these options work to make Spring boot attempt to use the application.properties file the same was as Spring boot 1.3.
Anyone know what I am missing? Thanks.
