Can anyone help?Thank you

That would suggest you don't have all you dependencies in you jar. Are you running correct jar - you might have more than one - one with app and one from boot in a different dir. Would be good to see a command you use to build as well.

My jar running well, after i choose to manual config Database connection
add in Application class
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
and then
create
#Configuration
#PropertySource({ "classpath:app.datasource.properties" })
class DatabaseConfig {
#Autowired
private Environment env;
#Bean
#Primary
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("app.datasource.driverClassName"));
dataSource.setUrl(env.getProperty("app.datasource.url"));
dataSource.setUsername(env.getProperty("app.datasource.username"));
dataSource.setPassword(env.getProperty("app.datasource.password"));
return dataSource;
}
i don't know why my jar can't get autoconfiguration from spring, maybe someone can explain in comments below

Spring boot data source auto configuration for PostgreSql failing

I am setting up a Springboot(version 2.0.4) project with maven build to use PostgreSQL database. I want to utilize data-source auto configuration feature of Springboot but it is giving me following errors:
Field dataSource in com.praveen.demo.MyController required a bean of type 'javax.sql.DataSource' that could not be found.
Bean method 'dataSource' not loaded because #ConditionalOnClass did not find required class 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType'
Bean method 'dataSource' not loaded because #ConditionalOnClass did not find required classes 'javax.transaction.TransactionManager', 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType'
In my pom.xml I've dependencies on postgresql and HikariCP as below:
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
</dependency>
<dependency>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
</dependency>
Also I've in my application.properties file
spring.datasource.url=jdbc:postgresql://localhost:5432/mydb?user=myself&password=mypassword
In my Java file having #RestController annotation , I am injecting DataSource as below:
#Autowired
private DataSource dataSource;
I am following below artcile: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html
I do not want to use JPA. I believe article is not suggesting to use the JPA for auto configuration to work.
I am expecting that Spring boot should auto-configure Data source for the application as I've declared the dependencies and provided the database URL. Still I get errors(as mentioned on top) on starting the application.
Edit-1: I am following below article:
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html

Although, I am still confused by the documentation provided at https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html and was expecting that I should not be required to use JPA for auto-configuration to work if I am explicitly declaring a dependency on HikariCP and Postgresql. Closing it for now.

Your pom is fine if you don't want to use JPA.
Define #Bean for Datasource to configure or add property in application.properties spring.datasource.type=com.zaxxer.hikari.HikariDataSource:
#Configuration
public class DbConfig {
#Bean
#ConfigurationProperties("spring.datasource")
public HikariDataSource dataSource() {
return DataSourceBuilder.create().type(HikariDataSource.class).build();
}
}
also change your properties to below:
spring.datasource.url=jdbc:postgresql://localhost:5432/mydb
spring.datasource.username-myself
spring.datasource.password= mypassword
Note: JPA configure for you everything so if not using JPA then you need to configure DataSource by telling about Hikari.
As per reference document 29.1.2 Connection to a Production Database
If you use the spring-boot-starter-jdbc or
spring-boot-starter-data-jpa “starters”, you automatically get a
dependency to HikariCP.
You can bypass that algorithm completely and specify the connection
pool to use by setting the spring.datasource.type property. This is
especially important if you run your application in a Tomcat
container, as tomcat-jdbc is provided by default.
[Tip] Additional connection pools can always be configured manually.
If you define your own DataSource bean, auto-configuration does not
occur.

H2-In memory database console not opening

I am using the H2 database in a Spring boot application. But unable to open it in the browser at http://localhost:8080/console. My pom.xml is as below:
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.192</version>
</dependency>
Spring boot Configuration :
Springboot configuration file
#Configuration
public class WebConfiguration {
#Bean
ServletRegistrationBean h2servletRegistration(){
ServletRegistrationBean registrationBean = new ServletRegistrationBean( new WebServlet());
registrationBean.addUrlMappings("/console/*");
return registrationBean;
}
}

to use the H2 console you need to configure it in your .properties file
spring.h2.console.enabled=true
spring.h2.console.path=/h2console/
where /h2console/ is the path you want to use on the browser so you can change it to anything. Also if you have security enabled you might want to add it to the permitted paths
also add this to your HttpSecurity configuration http.headers().frameOptions().disable();
Edit
change your security configuration i'm pretty sure you might have spring security in your pom so use this instead, if not it should work
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
#Configuration
public class WebConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests().antMatchers("/").permitAll().and()
.authorizeRequests().antMatchers("/console/**").permitAll();
httpSecurity.csrf().disable();
httpSecurity.headers().frameOptions().disable();
}
}

If have included spring-boot-starter-security artifact in your pom then by default basic authentication is enabled. Hence, to access your console either you disable the basic authentication by adding security.basic.enabled=false in your application.properties or allow the access in your configure method as below:
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.csrf().disable().authorizeRequests().antMatchers("/").permitAll().and().authorizeRequests()
.antMatchers("/console/**").permitAll();
httpSecurity.headers().frameOptions().disable();
}
}

Thank you all for your generous help.The application class (Springboot) was in a separate package and it was not scanning other packages.Also I modified my Pom.xml a bit which finally helped me to access the console.Attached is my new Pom.xml.

this might help folks , all the configuration above is correct
Note - if you are not using any security then adding spring security is not required
Actualy problem is - when you open this url in chrome
http://localhost:8080/h2 chrome makes it --> https://localhost:8080/h2
To get rid of this issue - Below reference will help -
Google Chrome redirecting localhost to https

You might have face 2 situation including following errors:
localhost refused to connect
Double check the URL. Chrome automatically try to change http:// to https://
Check spring.h2.console.path (Path at witch the console avilible) to get your URL:
Default: /h2-console --> URL: http://localhost:8080/h2-console/
If you running IDE (e.g. IntelliJ Idea), make sure your app is running witch means your H2 data base is running!
You face 404 Error:
In this case your H2 Data base is correctly running on Port 8080 and you already have the connection with it.
Check spring.h2.console.path (Path at witch the console avilible) to get your URL:
Default: /h2-console --> URL: http://localhost:8080/h2-console/
Enable H2 Console
spring.h2.console.enabled=true

The issue might be also be caused by adding server.servlet.context-path to properties. The new url will be composed of server.servlet.context-path plus spring.h2.console.path

If you have renamed the h2 path in the application.properties to "console" you've to add it in your antMatcher like .antMatcher("/console/**") with two asterisks after the "console" because there are much more appendings.

If none of the above solution works, try below one, this worked for me :
Add below property in your application.propertiesfollowing
spring.data.jpa.repositories.bootstrap-mode=default
Open console in browser using this URL : http://localhost:8080/h2-console
On a login page make sure that you use jdbc:h2:mem:testdb as JDBC URL.

As h2 database console is mapped to "h2-console".
Use this:
http.csrf().disable().authorizeRequests()
.antMatchers("/h2-console/**").permitAll()
.anyRequest().authenticated();
// disable frame options
http.headers().frameOptions().disable();
`
You don't need permit root access:
.antMatchers("/") * NOT NEEDED *

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

When u put the JPA hibernate jars are brought into classpath. And when Hibernate is available in classpath Spring Boot AutoConfiguration is picked for Creating the EntityManager.
This is the default behaviour of Spring boot.
Since you dont have any datasource for Hibernate the startup is failing.
Try creating a datasource by giving properties in your application.properties / yml file.
If u dont want to use hibernate or jpa then remove jpa starter from your pom.xml

How to create a simple CRUD application using Spring Data JPA and MYSQas DB using SpringBoot?

My directory structure for project is :
However with the same approach the above application works with SpringBoot version 1.3. Any suggestions how to make it work with version 1.4.4?

in your application.properties add this lines
spring.datasource.url = jdbc:mysql://localhost:3306/yourdatabase
# Username and password
spring.datasource.username = root
spring.datasource.password =
# Show or not log for each sql query
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = create
# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

Make sure your mysql-connector is actually there in the classpath at runtime (if your using Tomcat, then it should be in the lib folder).
If you do not have it there add a compile dependency in your pom.xml
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.36</version>
</dependency>
Also you forgot about this line in your application.properties:
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

You can restore that behaviour by creating your own datasource bean:
#Bean
public DataSource dataSource() {
return DataSourceBuilder
.create()
.username("")
.password("")
.url("")
.driverClassName("")
.build();
}
