I am migrating the application from 2.23.2 to 3.1.0 version.
The application works fine having 2 routes.
But a mbean is not exposed in jconsole.
There are basic mbeans in jconsole.
- JMImplementation
- com.sun.management
- com.zaxxer.hikari
- connector
- java.lang
- java.nio
- java.util.logging
- javax.management.remote.rmi
- org.apache.logging.log4j2
- org.springframework.boot
How can I handle this issue?
You need to add a dependency to your project for camel-management. For example:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-management</artifactId>
<version>3.1.0</version>
</dependency>
There's a note about this in the Camel 3.x upgrade guide:
https://camel.apache.org/manual/latest/camel-3x-upgrade-guide.html#_spring_boot_jmx
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

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.
I have upgraded Camel 2.22. along with CXF version 3.2.5,Spring boot 2.04.RELEASE
When I start my application I can't see any errors but the can't access endpoints anymore
below is the code:
1) Camel route:
<cxf:cxfEndpoint id="porEndpoint" address="/por/" serviceClass="x.y.z.service.PorService" publishedEndpointUrl="">
<cxf:binding>
<soap:soapBinding version="1.2"/>
</cxf:binding>
</cxf:cxfEndpoint>
2) Properties:
cxf.path=/services
server.servlet.context-path=/fuse-test
3)This URL worked fine earlier :http://localhost:8080/fuse-test/services/por?wsdl
I have enabled trace at context level and log mode as debug but I can't find any errors apart from :
o.s.s.ldap.SpringSecurityLdapTemplate : Ignoring PartialResultException
camel-cxf(v 3.2.5) somehow doesn't include the cxf spring boot. After adding the below dependency the endpoint is available
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-spring-boot-starter-jaxws</artifactId>
<version>3.2.6</version>
</dependency>
The Spring Boot guide says I can get the H2 console but it's not working for me.
http://localhost:8080/h2/ Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Wed Oct 26 12:31:46 BST 2016
There was an unexpected error (type=Not Found, status=404).
No message available
I created an application.properties file as follows
spring.h2.console.enabled=true
spring.h2.console.path=/h2
My project is based on this
The default path /h2-console doesn't work either.
I found another answer where the problem is solved by adding to Application.java:
#Bean
public ServletRegistrationBean h2servletRegistration() {
ServletRegistrationBean registration = new ServletRegistrationBean(new WebServlet());
registration.addUrlMappings("/h2/*");
return registration;
}
Everything in my application.properties file is ignored. I have tried adding:
spring.datasource.url=jdbc:h2:file:~/portal;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
But the database is still created in memory only.
Check if you set a base path in application.properties.
For example, if you have a setting
server.contextPath=/api
You access the h2 Console under
http://localhost:8080/api/h2-console
Obvious, but that was it for me
Another possible cause for this problem, is if you're using spring security.
In that case, you may want to add a specific permission to the h2-console URL you defined.
For example, for the default h2-console configuration (without a spring.h2.console.path property), you will add this inside your WebSecurityConfigurerAdapter extending class:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/h2-console/**").permitAll()
.anyRequest().authenticated();
http.headers().frameOptions().sameOrigin();
}
Please also note that line at the end - http.headers().frameOptions().sameOrigin();.
It's needed to prevent a Whitelable page error when logging in to the console.
This is described also here.
Your current location src\main\java\hello\application.properties is the culprit. For 2 reasons.
Non java resources in src\main\java are ignored
only application.properties in the root or config directory or taken into account (by default). (See the reference guide).
The fix is to simply move your application.properties to src\main\resources.
In my case, I just had to remove the tag <scope>runtime</scope> from the h2 dependency as explained in here.
a / is missing before spring.h2.console.path it have to look like :
spring.h2.console.path=/h2
also when you indicate spring.h2.console.path /h2-console is no more available
Regards
I tried h2-console while building my microservice project and fell into the same issue "Whitelabel error page".
I haven't added any security in my project for now but I found the problem for me is solved by removing spring.h2.console.enabled= true from application.properties and adding dependency dev-tools. for me not adding dev-tools also caused the problem so try to add this dependency as well. while of course, you will add h2, actuator, web dependencies.
Try the below in application.properties
spring.h2.console.enabled: true
try to add to application.properties
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
//then
create class SecurityConfig
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests().antMatchers("/").permitAll().and()
.authorizeRequests().antMatchers("/h2-console/**").permitAll();
httpSecurity.csrf().disable();
httpSecurity.headers().frameOptions().disable();
}
}
For me scope=test was the issue as I carelessly copied from https://mvnrepository.com/artifact/com.h2database/h2/1.4.200
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.200</version>
<scope>test</scope>
</dependency>
And replaced it with
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.200</version>
<scope>runtime</scope>
</dependency>
After this, it should work with default configurations.
I am not using spring security, but you might need to make certain changes accordingly. Please check above answers for that https://stackoverflow.com/a/59729714/7359806
First, make sure to have these dependencies:
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
Then add these to your application.properties:
##spring.main.web-application-type=none make sure it's commented
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console
##server.port=9999 make sure you use default port (8080). In other words, don't specify a server.port
For me - a computer restart fixed it.
Not sure why this would be the cause but perhaps a port was occupied, or the h2 related files were not deployed correctly
make sure you that when the springBoot application is launched, you can see the log lines for Hibernate and H2 are present:
2017-04-22 14:41:03.195 INFO 912 --- [ main] org.hibernate.Version : HHH000412: Hibernate Core {5.0.12.Final}

2017-04-22 14:41:03.945 INFO 912 --- [ main] org.hibernate.tool.hbm2ddl.SchemaExport : HHH000230: Schema export complete
For this problem, i just add the default string at my application.properties and works.
spring.datasource.url=jdbc:h2:file:~/test
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
Maybe the spring boot dont set this for some reason.
Remove <scope>test</scope> from h2 dependency in pom.xml works in my case.
Don't forget to reinstall and build again after your modification.
<!-- H2 database -->
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.199</version>
<!-- <scope>test</scope> -->
</dependency>
I used compile otherwise testCompile in the Gradle declaration and was worked fine for me.
Example:
compile group: 'com.h2database', name: 'h2', version: '1.4.200'
If you are having troubles with the program ignoring the application.properties and you are using Eclipse, do the following:
Move the application.properties into the src/main/resources folder, right click on it and click "build path" -> "Add to build path"
Make sure to use> spring.datasource.url=jdbc:h2:mem:testdb as this db is required for h2
I found the same case using Eclipse 4.26.0
Did some of above method and not work. Until in one forum, someone suggest us to add devtools dependency.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
I hope it works for you.
It appears there is still an issue with Spring Boot and libuibase 3.3.x.
2015-02-16 11:07:34.117 WARN 7576 --- [ main] liquibase : Error initializing SpringLiquibase
java.io.FileNotFoundException: ServletContext resource [/] cannot be resolved to URL because it does not exist
at org.springframework.web.context.support.ServletContextResource.getURL(ServletContextResource.java:156) ...
The same problem was noted already here on stackoverflow and the answer was that new version of Spring Boot 1.2.1 contains a patch for this issue but it seems still to be a problem with SB 1.2.1 and liquibase 3.3.0 (this is the version number of liquibase that SB 1.2.1 provides by default).
I'm just wondering if others who are using SB 1.2.1 and liquibase observe the same issue and maybe there is a solution to it.
Yes, I observe the same, my solution was to use a previous liquibase version, as it seems SB 1.2.1 still has problems with 3.3.1.
This version did the trick:
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
<version>3.2.1</version>
</dependency>
