i am doing that tutorial at the moment:
https://github.com/ubilife/tutorials/tree/master/spring/tutorial4
When I clone the repository everything works exactly like it is writte there.
The tutorial had among others this class:
Config.java
#Configuration
#ComponentScan
public class Config {
#Bean
public DataSource datasource() {
return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).addScript("schema.sql").build();
}
#Bean
public JdbcOperations jdbcTemplate(DataSource ds) {
return new JdbcTemplate(ds);
}
}
Now I tried to make use of what I've learned. I use SpringBoot with Intellij Ultimate 20017 and I wrote among others that class
#Configuration
#ComponentScan
public class SpringRootConfig {
#Bean(name = "scriptedDataSource")
public DataSource datasource() {
return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).addScript("schema.sql").build();
}
#Bean
public JdbcOperations jdbcTemplate(#Qualifier("scriptedDataSource") DataSource dataSource) {
System.out.println("jdbcTemplate()");
return new JdbcTemplate(dataSource);
}
}
First I had the Problem of duplicate Beans which Intellij could not handle. I solved that by use Qualifiers as you can see.
But now I got a new Error which I cannot solve with google.
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

So first of all I dont understand why cloning the tutors code is working fine and as soon as I try it fails (I even copied for test reasons his config.java but still get errors!)
And of course it would be super nice if you can help me to solve this problem.
Thank you a lot!
If you need any more files please just ask.
My Repo is here https://github.com/realsony/h2TestEnv/tree/master/src
From the exception that you posted, it looks like it cannot find your schema.sql file:
Caused by: java.io.FileNotFoundException: class path resource [schema.sql] cannot be opened because it does not exist
Make sure your schema.sql file is in the right place, or update your code to point to where your schema.sql file actually is.

I am trying to use FF4J in my project, and i have added following dependencies to my build.gradle file.
org.ff4j:ff4j-spring-boot-starter:1.8.7,
org.ff4j:ff4j-web:1.8.7
I am observing below error during server startup after adding these dependencies:

I guess this issue with version compatibility between FF4J and Springfox. The springfox version i am using is 2.4.0. I tried with multiple combinations, however, left with no clue.
Please check and help. Thanks.
I can confirm that current version of ff4j is using the Swagger 3.0.0 which seems not backward compatible with 2.4.0.
Multiple options:
The spring-boot-starter should be used when you exposing the REST-API and webconsole. This component should be in standalone component without your code. Then in microservices you import ff4j library only with the store you need sample code and video
You update your spring-fox dependency.

I searched on the Google and other site and found some solutions that suggested to edit the redis.conf and set the "notify-keyspace-events" to be "Egx".
I did it. But it not worked.
I also got some other suggestions. But these suggestions do not look like fitting for the problem.
So does any one has suggestion to help me to solve the problem? Thanks.

My application.yml looks like:
spring:
datasource:
driverClassName: org.postgresql.jdbc.Driver
url: jdbc:postgresql://<server_addr>/<db_name>
username: postgres
password: <pwd>
And I have the following dependency in my pom.xml:
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.4-1206-jdbc42</version>
</dependency>
I have searched for this issue on Stackoverflow but as far as I can tell, I am doing all the required steps. Can anyone help?
The driver classname is not correct. I just checked the version you're using (which is also wildly out-of-date) - it doesn't even contain "org.postgresql.jdbc" as a package.
The driver classname should be:
org.postgresql.Driver
Since most jar files are simple ZIP files, you can always manually unzip the jar and manually examin what's inside (most IDEs will do that for you). With errors such as this ("Cannot load class" or "Class not found") this can help to determine wether the class is there or not. In your case, it's not.
i am using spring boot framework to upload a file, i want to specify the location of a class, then i can upload the file to a dynamic location.
Btw, the strange thing is that this was working in intellij, but after I performed a Clean and Build on the Project, then running, it suddenly stopped working
main application:
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(SmartDustbinServiceApplication.class, args);
}
#Bean
MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setLocation(PathKit.getWebRootPath());
return factory.createMultipartConfig();
}
and the class PathKit have a method like this:
private static String detectWebRootPath() {
try {
String path = PathKit.class.getResource("/").toURI().getPath();
return new File(path).getParentFile().getParentFile().getCanonicalPath();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
then I have got the following exceptions when i starting my springboot project;

The project was run without errors and worked correctly. I did not make any changes in code and then in one moment I got this exception.
Here is my JpaConfig:
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories({
"com.webstore.common.repository.jpa",
"com.webstore.web.repository.jpa"
})
public class JpaConfig implements TransactionManagementConfigurer {
#Value("${dataSource.url}")
private String datasourceUrl;
#Value("${dataSource.username}")
private String datasourceUsername;
#Value("${dataSource.password}")
private String datasourcePassword;
#Value("${dataSource.driverClassName}")
private String datasourceDriverClassName;
#Value("${hibernate.dialect}")
private String hibernateDialect;
#Value("${hibernate.hbm2ddl.auto}")
private String hibernateHbm2ddlAuto;
#Bean
public DataSource configureDataSource() {
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setDriverClassName(datasourceDriverClassName);
hikariConfig.setJdbcUrl(datasourceUrl);
hikariConfig.setUsername(datasourceUsername);
hikariConfig.setPassword(datasourcePassword);
return new HikariDataSource(hikariConfig);
}
#Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean configureEntityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(configureDataSource());
entityManagerFactoryBean.setPackagesToScan("com.webstore");
entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
Properties jpaProperties = new Properties();
jpaProperties.put(org.hibernate.cfg.Environment.DIALECT, hibernateDialect);
jpaProperties.put(org.hibernate.cfg.Environment.HBM2DDL_AUTO, hibernateHbm2ddlAuto);
entityManagerFactoryBean.setJpaProperties(jpaProperties);
return entityManagerFactoryBean;
}
#Bean
#Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new JpaTransactionManager();
}
}

Thanks in advance!
I see you have a reliance on snapshot versioning in your pom.xml .This means you will pull any recent releases which may not be fully bug free. If you look in your error message you will see
spring-boot-1.4.0.BUILD-20160727.140415-585.jar:1.4.0.BUILD-SNAPSHOT
This is a version built today which might not be fully stable. Instead change your pom to use the current general availability version for stability
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.6.RELEASE</version>
