This should solve your problem cause it works well at my spring boot app. Good luck!

Spring Fox 2.9 is only compatible with version 1.2 of spring-plugin-core whereas the version of Spring Data REST included in Spring Boot 2.2 requires 2.0. Until a compatible version of SpringFox is released, you have a few options:
remove SpringFox from your app
remove Spring Data REST from your app
downgrade to Spring Boot 2.1.x
To run with latest version of Spring boot, add the below dependency,
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-hal-explorer</artifactId>
</dependency>
I am trying to learn microservices by creating a dummy project.

Now I have two microservice projects 1) customer service and 2) customer-account-service. customer microservice is running properly while customer-account-microservice is unable to start and throwing below exception:

Please help me in fixing the above exception.
It seems that your dependency
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
has to be in dependencies element, not in dependencyManagement. Just look at this. Or maybe you have a child artifact, in that case you must share another pom xml.
I change it to 'compile' and it solved my problem.
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.200</version>
<scope>compile</scope>
</dependency>
in my case, I had a space after the "driver"
spring.datasource.driverClassName=org.h2.Driver...
I deleted it and it works just fine
I was facing the same issue in IDEA IntellJ even after using the correct dependency in pom.xml. It boils down to IDE specific issue where it was not able to download h2 dependency. It worked after restarting the IDE.
In my case the problem was caused by some trailing blank characters behind the driver classname in application.properties
This fails (dots in the code snippet below should be read as whitespace chars):
spring.datasource.driverClassName=org.h2.Driver...
This succeeds:
spring.datasource.driverClassName=org.h2.Driver
I commented spring.datasource.driverClassName=org.h2.Driver, that worked like a charm for me
In my case I gave the gradle dependency wrong.
I should give it in dependencies {implementation}, but I gave it in dependencies {testImplementation} in build.gradle file
The below mentioned is right
dependencies {
implementation 'com.h2database:h2:2.1.212'
}
I had this problem because I was using an outdated version of the h2 dependency :
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.193</version>
</dependency>
I fixed it by removing the version tag so that the latest version is downloaded :
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>
I hope you have added dependencies now add spring.datasource.platform=h2 in your application.properties
it worked for me
In my case,
In application.properties file, there are white spaces after adding configurations
You can see IDEA IntellJ like this
Should remove all the white spaces in application.properties file. Then the test cases failed issue will be solved
Hibernate is generating temporary tables for TABLE_PER_CLASS inheritance but the prod. oracle user does not have those create table priviledges and therefore that approach is not an option for our project.
Hibernate Version 5.2.8 is said to resolve that issue.
We updated our pom.xml accordingly to override default starter hibernate version setting.
Still we dont have any luck with the following property.
<property name="hibernate.hql.bulk_id_strategy"
value="org.hibernate.hql.spi.id.inline.InlineIdsInClauseBulkIdStrategy"
/>
APPLICATION PROPERTIES is also updated as follows
**
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.url=jdbc:oracle:thin:#192.168.1. :1521:
spring.datasource.username=
spring.datasource.password=
spring.jpa.hibernate.ddl-auto=none
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
spring.jpa.show-sql=true
spring.jpa.hibernate.hql.bulk_id_strategy=org.hibernate.hql.spi.id.inline.InlineIdsInClauseBulkIdStrategy
**
Where is the proper location of this setting in a spring boot app?
The container is still generating temp tables in the test env. server startup.
kind regards

In addition all properties in spring.jpa.properties.* are passed through as normal JPA properties (with the prefix stripped) when the local EntityManagerFactory is created.
This comes from the JPA section in the Spring Boot reference guide and, in a nutshell, explains how to pass additional provider specific properties.
Adding the following to your application.properties should do the trick
spring.jpa.properties.hibernate.hql.bulk_id_strategy=org.hibernate.hql.spi.id.inline.InlineIdsInClauseBulkIdStrategy
As suggested by M.Deinum above, you should add the following to your application.properties file:
spring.jpa.properties.hibernate.hql.bulk_id_strategy=org.hibernate.hql.spi.id.inline.InlineIdsInClauseBulkIdStrategy
and also add the following to the properties section of your pom.xml to override the bundled hibernate-core library. This is to ensure that the InlineIdsInClauseBulkIdStrategy class is found, as the class is only available in Hibernate Core 5.3.1.Final and above:
<properties>
...
<hibernate.version>5.3.1.Final</hibernate.version>
</properties>
I have a spring boot based project with following declaration in pom.xml:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->

<artifactId>spring-boot-starter-data-jpa</artifactId>

<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
But seems like spring boot is not pulling in SecurityEvaluationContextExtension class on the classpath.
Am I missing a dependency or am I using an older version of spring boot?
EDIT:
I directly added the following dependency in my pom.xml and now I can see the class, but STS is showing warning : "Duplicating managed version 4.0.3.RELEASE for spring-security-data"
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-data</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>
I am not shure what you mean with 'spring is not pulling in..'
But to use this extension you have to create a bean of this type see
SecurityEvaluationContextExtension
EDIT :
The warning you are getting is no problem. You can try removing the version from the dependency, because it seems available through dependencyManagement.

Here is the error I get :
java.lang.LinkageError: loader constraint violation: when resolving method "org.apache.jasper.runtime.InstanceManagerFactory.getInstanceManager(Ljavax/servlet/ServletConfig;)Lorg/apache/tomcat/InstanceManager;" the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/WEB_002dINF/views/agreement2/index_jsp, and the class loader (instance of java/net/URLClassLoader) for resolved class, org/apache/jasper/runtime/InstanceManagerFactory, have different Class objects for the type .getInstanceManager(Ljavax/servlet/ServletConfig;)Lorg/apache/tomcat/InstanceManager; used in the signature
I think it has a relation with el or jsp-api version, I try to add manually in the pom.xml but got same error or sometimes 'noClassDefFoundError on my compiled jsp'
Does someone see what's going wrong?
Due to your dependency on spring-boot-starter-web and spring-boot-starter-websocket and their transitive dependencies, you're packaging Tomcat inside your war file. This is leading to there being two different versions of Tomcat's classes available and is caused the constraint violation. You need to mark the Tomcat dependencies as provided so that they don't get packaged in WEB-INF/lib.
Add the following dependencies to your pom:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-websocket</artifactId>
<scope>provided</scope>
</dependency>
It's preferable to mark the dependencies as provided, rather than excluding them altogether, as it allows your war file to be deployed to Tomcat or executed with java -jar. This works because the provided dependencies are packaged in WEB-INF/lib-provided where they'll be ignored by a standalone Servlet container but be available when you're using the embedded container.
In gradle I added this line to dependencies:
dependencies {
...
providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
...
}
