Connecting Spring Boot web app to a postgresql server

Connecting Spring Boot web app to a postgresql server - java

I'm making a web application using Spring Boot and I have the functionality I want by using a in memory database(H2) but I can't connect it to the postgresql server I set up on my computer. I've been at this for some time and tried a bunch of stuff that didn't work so I set everything back to the way it was just to get it working again.
Here's my UploadController.java, it handles the upload from the server and puts it into my in memory database:
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import project.service.MediaFile;
import project.service.MediaFileRepository;
#Controller
public class UploadController {
#Autowired
private MediaFileRepository repository;
#RequestMapping(value = "/uploadmedia", method = RequestMethod.GET)
public String uploadForm() {
return "upload";
}
#RequestMapping(value = "/uploadmedia", method = RequestMethod.POST)
public String uploadSubmit(#RequestParam(value="files[]") MultipartFile[] files,
#RequestParam("tags") String tags, #RequestParam("type") String type)
{
String[] tagsArray = tags.split("\\s+");
MultipartFile file;
String name;
String tag;
String path;
for (int i = 0; i < files.length; i++) {
file = files[i];
name = file.getOriginalFilename();
path = "/Users/johannesthorkell/Developer/spring_prufa/images/" + name;
System.out.println(name);
if (!file.isEmpty()) {
try {
byte[] bytes = file.getBytes();
BufferedOutputStream stream =
new BufferedOutputStream(new FileOutputStream(new File(path)));
stream.write(bytes);
stream.close();
for (int j = 0; j < tagsArray.length; j++) {
tag = tagsArray[j].toLowerCase();
repository.save(new MediaFile(name, tag, path, type));
}
System.out.println("Success!");
} catch (Exception e) {
System.out.println("Failure... " + e.getMessage());
}
} else {
System.out.println("No file");
}
}
return "upload";
}
}
...and here's my MediaFile class, the #Entity object:
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class MediaFile {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
private String name;
private String tag;
private String resource;
private String type;
protected MediaFile() {}
public MediaFile(String name, String tag, String resource, String type) {
this.name = name;
this.tag = tag;
this.resource = resource;
this.type = type;
}
public String getTag() {
return tag;
}
#Override
public String toString() {
return String.format(
"MediaFile[id=%d, name='%s', tag='%s', resource='%s', type='%s']",
id, name, tag, resource, type);
}
}
...here's my pom.xml:

...and finally, here's the application.properties:
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp

With this setup everything works. I tried putting the following in my application.properties:
spring.datasource.url=jdbc:postgresql://localhost/test
spring.datasource.username=myusername
spring.datasource.password=mypassword
spring.datasource.driver-class-name=org.postgresql.jdbc.Driver
...Along with adding the following dependency to the pom.xml:
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.4-1200-jdbc41</version>
</dependency>
...And then I tried mixing and matching these things and reading tutorials for a few hours to no avail.
Edit:
I removed one line and added another (at the advice of Stéphane Nicoll) so now my application.properties look like this:
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp
multipart.maxFileSize=-1
debug=true
spring.datasource.url=jdbc:postgresql://localhost:5432/mydb

With the changes to my application.properties my app now runs! But I get the following error when I submit to my POST form to UploadController.java:

Hibernate's looking for a table named hibernate_sequence to support #GeneratedValue on MediaFile. You've configured it with AUTO at the moment. The actual behaviour then varies depending on the database you're using.
I think you have a couple of options:
Create a sequence in Postgres (CREATE SEQUENCE), named hibernate_sequence
Change to using a different generation type, e.g. GenerationType.IDENTITY

If I were you, I'd create my own dataSource bean, like:
#Configuration
public class MyConfig{
#Autowired
Environment env;
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("myapp.dataSource.driver"));
dataSource.setUrl(env.getProperty("myapp.dataSource.url"));
dataSource.setUsername(env.getProperty("myapp.dataSource.username"));
dataSource.setPassword(env.getProperty("myapp.dataSource.password"));
return dataSource;
}
}
application.properties:
logging.level. = INFO
myapp.dataSource.driver =
myapp.dataSource.url =
myapp.dataSource.username =
myapp.dataSource.password =
IF you don't want to try this, you could try changing your driver org.postgresql.jdbc.Driver to org.postgresql.Driver.
It's hard to help without any logs.

DynamoDB: Filed to configure a DataSource. 'url' attribute is not specified and no embedded datasource could be configured

How to correctly use DynamoDB with Spring?
I tried to follow many tutorials but always got the same error.
For example my realization of [baeldung tutorial][1]:
application-properties:
#AWS-creds
amazon.dynamodb.endpoint=https://dynamodb.us-east-1.amazonaws.com
amazon.aws.accesskey=
amazon.aws.secretkey=
spring.jpa.hibernate.ddl-auto=create
spring.main.allow-bean-definition-overriding=true
configuration:
#Configuration
#EnableDynamoDBRepositories
(basePackages = "com.hrzc.demo.repository")
public class DynamoDBConfig {
#Value("${amazon.dynamodb.endpoint}")
private String amazonDynamoDBEndpoint;
#Value("${amazon.aws.accesskey}")
private String amazonAWSAccessKey;
#Value("${amazon.aws.secretkey}")
private String amazonAWSSecretKey;
#Bean
public AmazonDynamoDB amazonDynamoDB() {
AmazonDynamoDB amazonDynamoDB
= new AmazonDynamoDBClient(amazonAWSCredentials());
if (!StringUtils.isEmpty(amazonDynamoDBEndpoint)) {
amazonDynamoDB.setEndpoint(amazonDynamoDBEndpoint);
}
return amazonDynamoDB;
}
#Bean
public AWSCredentials amazonAWSCredentials() {
return new BasicAWSCredentials(
amazonAWSAccessKey, amazonAWSSecretKey);
}
}
entity:
#DynamoDBTable(tableName = "Url")
public class Url {
private int id;
private String longUrl;
#DynamoDBAttribute
#DynamoDBRangeKey
public String getLongUrl() {
return longUrl;
}
public void setLongUrl(String longUrl) {
this.longUrl = longUrl;
}
#DynamoDBHashKey
#DynamoDBAutoGeneratedKey
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
repository:
#EnableScan
public interface UrlRepository extends CrudRepository<Url, Long> {
}
The pom file does not equal the pom from the tutorial, but I hope this is not the reason, since I can't start the project with dependencyManagement - the error sounds like An attempt was made to call a method that does not exist. - and I found the suggestion to remove the spring-boot-data overriding [here][2].

check your application properties file
#for mysql
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#for postgres
#spring.datasource.driver-class-name=org.postgresql.Driver
my properties file is with other config is like
spring.datasource.name=localSource
spring.datasource.url=jdbc:mysql://localhost:3306/db
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.database-platform = org.hibernate.dialect.MySQL8Dialect
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto = update
sometimes also check to update maven dependency by updating the maven (sts4/ eclipse)

Spring field required a bean of type that could not be found

I'm trying to make a Spring Boot Application with simple login page but when i try to use #Autowired with a interface that i created seems to be a problem. I read 7-8 similar questions but the answers that i find there was useless for me. #Autowired works fine when i use it on interface that expends JpaRepository.
my structure is:
My packages are on the same level as my Application file .
Here is my controller
#Controller
#RequestMapping(value = "/users")
public class LoginContoller {
#Autowired
UsersRepositoryCustom usersRepositoryCustom;
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginForm(){
return "login";
}
#RequestMapping(value = "/login", method = RequestMethod.POST)
public #ResponseBody
String verifyLogin(#RequestParam String name, #RequestParam String password) {
System.out.println("Controller: name: " + name + " pass " + password);
Users users=usersRepositoryCustom.loginUser(name, password);
if (users==null) {
System.out.println("login control user null");
return "login";
}
return "users/all";
}
}
Repository:
#Repository
public interface UsersRepositoryCustom {
Users loginUser(String name, String password);
}
I do not think it helps but here is the implementation
public abstract class UserImpl implements UsersRepositoryCustom {
#Autowired
UsersRepository usersRepository;
#Override
public Users loginUser(String name, String password) {
System.out.println("UserImpl: nume: " + name + " pass " + password);
Users user=usersRepository.findByUsername(name);
if (user != null && user.getPassword().equals(password)) {
System.out.println("User Login"+user.getId()+" "+user.getUsername());
return user;
}
return null;
}
}

My Problem:
WebMvcConfig.java class not executing the AuthenticateIntercepter.java, by which I'm not getting the logs in console. So anyone tell me where i made mistake.

Unable to autowire 2 beans of same type but different names even after using qualifier

I am working on a spring-boot application and I have a configuration class in which i have defined 2 beans of same type but with different names and i am using that bean as parameter to a different bean, i am using qualifier to have different names but still i am not able to autowire the bean
import com.typesafe.config.Config;
import com.typesafe.config.ConfigFactory;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import javax.sql.DataSource;
import java.io.File;
/**

#Configuration
public class DbConfig {
#Bean(name = "sourceJdbcTemplate")
public JdbcTemplate sourceJdbcTemple(#Qualifier("srcDataSource") DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
#Bean(name = "srcDataSource")
public DataSource sourceDataSource(Config config) {
String driverClassName = config.getString("dbPullConfig.Database.Source.driver");
String url = config.getString("dbPullConfig.Database.Source.url");
String userName = config.getString("dbPullConfig.Database.Source.username");
String password = config.getString("dbPullConfig.Database.Source.password");
DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
driverManagerDataSource.setDriverClassName(driverClassName);
driverManagerDataSource.setUrl(url);
driverManagerDataSource.setUsername(userName);
driverManagerDataSource.setPassword(password);
return driverManagerDataSource;
}
#Bean(name = "destDataSource")
public DataSource destinationDataSource(Config config) {
String driverClassName = config.getString("dbPullConfig.Database.Destination.driver");
String url = config.getString("dbPullConfig.Database.Destination.url");
String userName = config.getString("dbPullConfig.Database.Destination.username");
String password = config.getString("dbPullConfig.Database.Destination.password");
DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
driverManagerDataSource.setDriverClassName(driverClassName);
driverManagerDataSource.setUrl(url);

driverManagerDataSource.setPassword(password);
return driverManagerDataSource;
}
#Bean(name = "config")
public Config config() {
return ConfigFactory.parseFile(new File("DbPullConfig.conf"));
}
}
And i am getting the below error
parameter 0 of method sourceJdbcTemple in com.ambuj.risk.DbConfig required a single bean, but 2 were found:
- srcDataSource: defined by method 'sourceDataSource' in class path resource [com/ambuj/risk/DbConfig.class]

Please help me in fixing this error.....
Thanks in advance.....

I tested same example in my local machine with the following dependencies.
file paths are not correct if you are running it in windows.
check the code below.

path example:

It worked for me.

Did you include the dependency for Xstream in your maven file? If you are using maven please add the following to your project file:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-xstream</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>
The error clearly states you are missing a component
