Trying to use the following example from Spring Docs
#Bean
public MessageConverter userMessageConverter() throws IOException {
AvroSchemaMessageConverter avroSchemaMessageConverter {
return new AvroSchemaMessageConverter(MimeType.valueOf("avro/bytes");
}
Using Gradle as follows
buildscript {
ext {
springBootVersion = '1.4.2.RELEASE'
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'org.springframework.boot'
dependencies {
compile('org.springframework.cloud:spring-cloud-stream')
compile('org.springframework.cloud:spring-cloud-starter-stream-kafka')
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:Camden.SR2"
}
}
Gradle is loading the correct version of spring-cloud-streams 1.1.0.RELEASE but it does not match with the Github Repo. The artifact is missing the org.springframework.cloud.stream.schema package/source.
Am I missing something here?
The artifact org.springframework.cloud:spring-cloud-starter-stream-kafka brings in spring-cloud-stream, spring-cloud-stream-codec and related dependencies like spring-integration. You would have to explicitly define org.springframework.cloud:spring-cloud-stream-schema.
Also, you don't need to specify 'org.springframework.cloud:spring-cloud-stream' as it will be part of org.springframework.cloud:spring-cloud-starter-stream-kafka via org.springframework.cloud:spring-cloud-stream-binder-kafka.

I'm running into an issue with building a war with Gradle 4.8.1. Here is the build.gradle:
buildscript {
ext {
springBootVersion = '2.0.3.RELEASE'
}
repositories {
jcenter()
}
dependencies {
classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"
}
}
apply plugin: 'idea'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'org.springframework.boot'
apply plugin: 'war'
archivesBaseName = 'sample'
//war {
// archiveName = 'sample.war'
// group = 'my.group'
// version = '2.0.0-SNAPSHOT'
//}
sourceCompatibility = 1.8
repositories {
jcenter()
maven { url "${nexusUrl}/content/groups/public" }
}
dependencies {
// Spring
compile 'org.springframework.boot:spring-boot-starter-actuator'
compile 'org.springframework.boot:spring-boot-starter-data-jpa'
compile 'org.springframework.boot:spring-boot-starter-log4j2'

}

}
uploadArchives {
repositories {
mavenDeployer {
repository(url: "${nexusUrl}/content/groups/public/") {
authentication(userName: nexusUsername, password: nexusPassword)
}
snapshotRepository(url: "${nexusUrl}/content/repositories/snapshots") {
authentication(userName: nexusUsername, password: nexusPassword)
}
pom.version = '2.0.0-SNAPSHOT'
pom.artifactId = 'sample'
pom.groupId = 'my.group'
}
}
}
I also tried removing the 'maven' plugin, archivesBaseName, and the uploadArchive task while uncommenting the war task and I get the same result. When using uploadArchive the war deploys to the nexus server fine and I get no errors. When deploying the war to tomcat (in both instances) tomcat 7 and 8 throw no errors and I receive no logs from either catalina or the project, although archiveName inside the war task does not properly rename the war. I have tried this on two other machines/tomcat instances with the same result. When building this as a fat jar, or running this in IntelliJ, everything works as expected (including the logging).
Any help or direction would be greatly appreciated.
It sounds like it is not initializing the servlet at all. Make sure to extend the SpringBootServletInitializer for WAR deployment.
Spring Boot Docs - Traditional Deployment
I was also facing the same issue. The issue is Spring application doesnt get initialized when the war is deployed on tomcat.
After a lot of struggle, I figured out that I needed to extend SpringBootServletInitializer in my application. So my effective code looks like
public class SyncApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SyncApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(SyncApplication.class, args);
}
}
Looks like this SpringBootServletInitializer directs war plugins generate bootstrapping code while building the war, and thus spring context is initialized while deploying the app.
I have problem with setting up HEAD resposnse from RestController in Spring Boor. I'm currently using Spring Boot version 1.5.9.
I have settup new project for demostrating this problem. In application.properties I have just one line:
server.context-path=/api/v1
My RestController "TestController.java"
#RestController
public class TestController {
#GetMapping("/test")
public String test() {
return "test";
}
}
When I try to get only header with HTTP HEAD request on url http://localhost:8080/api/v1/test, then the response stack and I don't get any response. In app console there is no errors.
If I remove server.context-path=/api/v1 from application.properties. Then HEAD request to http://localhost:8080/test is working as expected.
Thank you for any help,
Martin
Here is the build.gradle
buildscript {
ext {
springBootVersion = '1.5.9.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-websocket')

I am going through the examples in Kotlin in Action book. The gradle buid script is as follows:
group 'kotlin-in-action'
version '1.0-SNAPSHOT'
buildscript {
ext.kotlin_version = '1.1.2-2'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: 'kotlin'
repositories {
mavenCentral()
}
apply plugin: 'java'
dependencies {
testCompile 'junit:junit:4.12'
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
compile "junit:junit:4.12"
compile 'junit:junit:4.12'
compile 'junit:junit:4.12'
}
sourceSets {
main.kotlin.srcDirs += 'src'
}
All the scripts compile except for two classes that uses junit.
package ch06.ex1_8_1_LateinitializedProperties
import org.junit.Before
import org.junit.Test
import org.junit.Assert
class MyService {
fun performAction(): String = "foo"
}
class MyTest {
private var myService: MyService? = null
#Before fun setUp() {
myService = MyService()
}
#Test fun testAction() {
Assert.assertEquals("foo",
myService!!.performAction())
}
}
The compiler says it can't find junit. I have tried adding the jar files in IntelliJ, but this has not resolved the problem. The jar files I have added are junit and hamscrest-core. This is all version 4.12.
I have resolved this. I had to add the Junit and hamcrest-core jar files from the mavan depository.
I am getting a class cannot be final, needs to be open, despite adding the kotlin-spring plugin. The whole purpose of the plugin is to not manually add the open keyword to every class.
Please guide me on getting the Kotling-Spring plugin to work with code below.
build.gradle
buildscript {
ext.kotlin_version = "1.1.2"
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-noarg:$kotlin_version"
}
}
apply plugin: "kotlin"
apply plugin: "kotlin-spring"
apply plugin: "kotlin-noarg"
apply plugin: "idea"
repositories {
mavenCentral()
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
compile"org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
compile "org.springframework:spring-context:4.3.8.RELEASE"
testCompile "org.springframework:spring-test:4.3.8.RELEASE"
testCompile "junit:junit:4.11"
}
AppConfig.java
#Configuration
class AppConfig {
#Bean
fun game(): Game {
return BaseballGame(redSox(),cubs())
}
#Bean
fun redSox(): Team {
return RedSox()
}
#Bean
fun cubs(): Team {
return Cubs()
}
}
Error:
Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: #Configuration class 'AppConfig' may not be final. Remove the final modifier to continue.
Offending resource: AppConfig
REF: https://kotlinlang.org/docs/reference/using-gradle.html#plugin-and-versions
Had the same problem. Enabling annotation processing in Intellij solved the issue:
Had similar problem. Couldn't run from IDE, but gradlew.bat build bootRun worked. Solved by updating Kotlin plugin in IDEA, from 1.2.40 to 1.2.41.
I too faced Similar Issue while Running Springboot Application . Finally I learnt that Kotlin Class are final by Default . You need to add open before class Name
So , you need to change class modifier as follows :
open class AppConfig {
Reference :
http://engineering.pivotal.io/post/spring-boot-application-with-kotlin/
My configration class looks as follow
#Configuration
#EnableAutoConfiguration
#ComponentScan(basePackages = "com.projectx")
public class Application extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(applicationClass, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
Also build.gradle file looks like this
apply plugin: 'java'
sourceCompatibility=1.8
targetCompatibility=1.8
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'
mainClassName = 'com.projectx.data.config.Application'
buildscript {
repositories {
maven { url "http://repo.spring.io/libs-release" }
mavenLocal()
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.1.RELEASE")
}
}
war {
baseName = 'gs-accessing-data-jpa'
version = '0.1.0'
}
repositories {
mavenLocal()
mavenCentral()
maven { url "http://repo.spring.io/libs-release" }
maven { url "https://repository.jboss.org/nexus/content/repositories/releases" }
}
configurations {
providedRuntime
}
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
}
So wherever i am deploying this project to tomcat it is showing following error. As I have mate all requirement to convert jar to war in spring not sure what is wrong this my project.
It gives 404 NOT FOUND.(I am using STS 3.6.0 with Gradle plugin)
