Spring MVC with multiple database connections

Spring MVC with multiple database connections - java

Hello I am building my first Spring MVC and Thymeleaf web app and I do not know how to connect to two different Oracle databases. I managed to connect to just one.
Here is the code:
Repository code:
package com.example.demo;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import java.util.Map;
import java.util.Set;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.dao.DataAccessException;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.stereotype.Repository;
/**

*/
#Repository
public class TelefonMailRepositoryImpl implements TelefonMailRepository {
private final DataSource dataSourceMail;
private final DataSource inregIvg;
public TelefonMailRepositoryImpl(DataSource dataSourceMail, #Qualifier("inregIvg") DataSource inregIvg) {
this.dataSourceMail = dataSourceMail;
this.inregIvg = inregIvg;
}
public Map<String, Object> findByNumber(String telefon) {
Map<String, Object> toateTel;
String query = "select cnp, nume, prenume from utilizatori where telefon=?";
JdbcTemplate jdbcTemplate = new JdbcTemplate(this.dataSourceMail);
jdbcTemplate.queryForMap(query,telefon);
Map<String, Object> info1 = jdbcTemplate.queryForMap(query,telefon);
// return info1;
String query2 = "select cif, den_client from b101_conturi where telefon=?";
JdbcTemplate jdbcTemplate2 = new JdbcTemplate(this.inregIvg);
Map<String, Object> info2 = jdbcTemplate.queryForMap(query2,telefon);
if(info2.isEmpty()) {
return info1;
} else {
return info2;
}
}
public Map<String, Object> findByEmail(String email) {
String query = "select cnp, nume, prenume from utilizatori where upper(email)=upper(?)";
JdbcTemplate jdbcTemplate = new JdbcTemplate(this.dataSourceMail);
Map<String, Object> info1 = jdbcTemplate.queryForMap(query, email);
String query2 = "select cif, den_client from b101_conturi where upper(email)=upper(?)";
JdbcTemplate jdbcTemplate2 = new JdbcTemplate(this.inregIvg);
Map<String, Object> info2 = jdbcTemplate2.queryForMap(query2,email);
if(info2.isEmpty()) {
return info1;
} else {
return info1;
}
}
public DataSource getDataSourceMail() {
return dataSourceMail;
}
}
This is the DbConfig file:
package com.example.demo;
import com.zaxxer.hikari.HikariDataSource;
import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
/**
*
* #author 40723
*/
#Configuration
public class DbConfig {
#Bean
#Primary
#ConfigurationProperties("app.datasource.dsmail")
public DataSourceProperties dsmailDataSourceProperties() {
return new DataSourceProperties();
}
#Bean(name="DSMail")
#Primary
#ConfigurationProperties("app.datasource.dsmail.configuration")
public HikariDataSource dataSourceMail() {
return dsmailDataSourceProperties().initializeDataSourceBuilder().type(HikariDataSource.class).build();
}
#Bean
#ConfigurationProperties("app.datasource.inregivg")
public DataSourceProperties inregIvgDataSourceProperties() {
return new DataSourceProperties();
}
#Bean(name = "inregIvg")
#ConfigurationProperties("app.datasource.inregivg.configuration")
public HikariDataSource dataSourceInregIvg() {
return inregIvgDataSourceProperties().initializeDataSourceBuilder().type(HikariDataSource.class).build();
}
}
And here are the application properties:
app.datasource.dsmail.username=xxx
app.datasource.dsmail.password=xxx
app.datasource.dsmail.url=dburl:123
app.datasource.dsmail.driver-class-name=oracle.jdbc.OracleDriver
app.datasource.dsmail.configuration.pool-name=DSMailPool
app.datasource.dsmail.configuration.auto-commit=false
app.datasource.inregivg.username=yyy
app.datasource.inregivg.password=yyy
app.datasource.inregivg.url=dburl2:321
app.datasource.inregivg.driver-class-name=oracle.jdbc.OracleDriver
app.datasource.inregivg.configuration.pool-name=DSInregivgPool
app.datasource.inregivg.configuration.auto-commit=false
I have changed the user, pass, and url of application props because of security reasons.
Can you tell me what I am doing wrong ?
The error that I get is:
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

Just as a reminder with one connection it works it retrieves the desired info but with two datasources it does not work. I made the select that spits the error in Toad and it works so the tabvle exists. Thanks in advance. Have a nice day !

The connection is successful but it can't be find a table in db. I think you need to separate package of models by each db and the configuration class should be know the package name for each db. For example for JPA:
#Configuration
#EnableJpaRepositories(
basePackages = "com.project.modelpackage"
)
public class ClassName { ... }

Spring boot security - AuthenticationManager problem

I found a problem. about security at the authenticationmanager.If i add final front it.
package com.authentication.jwt.token.controller;
import com.authentication.jwt.token.config.JwtUtils;
import com.authentication.jwt.token.entity.JwtTokenRequest;
import com.authentication.jwt.token.service.UserService;
import lombok.RequiredArgsConstructor;
import org.springframework.http.ResponseEntity;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
#RestController
#RequiredArgsConstructor
public class AuthenticationController {
private final JwtUtils jwtUtils;
private final UserService userService;
private final AuthenticationManager authenticationManager;
#PostMapping("/generate-token")
public ResponseEntity<String> generateToken(#RequestBody JwtTokenRequest request) throws Exception {
// JwtTokenResponse jwtToken = jwtService.createJwtToken(request);
authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(request.getUserName(), request.getUserPassword()));
UserDetails user = userService.findByUser(request.getUserName());
if (user != null) {
return ResponseEntity.ok().body(jwtUtils.generateToken(user));
}
return ResponseEntity.badRequest().build();
}
}
program will show >>

this is frist time of me for stackOverflow. If i do misprint or explain a problem not good. I apologize in advance and thank you to come in get hear problem me. thank you so much.
i try edit it to run not error, but stuck with a problem authenticationManager.
i add bean at the SecurityConfig already. but the program show message "not found typt bean".
please help me.

It seems to me that since you are using the jakarta namespace, you are using Spring Boot 3 and Spring Security 6.
In Spring Security 6, all Spring Security’s #Enable* annotations had their #Configuration removed.
The following annotations had their #Configuration removed:
#EnableGlobalAuthentication
#EnableGlobalMethodSecurity
#EnableMethodSecurity
#EnableReactiveMethodSecurity
#EnableWebSecurity
#EnableWebFluxSecurity
If the class is not a #Configuration, Spring will not consider it as a bean and therefore will not initialize the beans inside it.
You have to add #Configuration to your SecurityConfig class or it will not be picked up by Spring. More details on Spring Security documentation.

Spring Boot, Spring-Security - BcrypPasswordEncoder in new component-based security configuration

I am trying to use the new Component-Based (Without WebSecurityConfigurerAdapter) configuration and setted up my Security Configuration as follow:

}
but when I run the application and try to log a user the following error appears even though I have the BCryptPasswordEncoder as a bean in my SecurityConfiguration:

}
}

Judging by the stacktrace I assume your CustomAuthenticationFilter calls AuthenticationManager.authenticate() method on a UsernamePasswordAuthenticationToken object. That, by default, calls DaoAuthenticationProvider, which is created with a DelegatingPasswordEncoder, containing 11 password encoders, and which is trying to match passwords with this encoder (not your BCryptPasswordEncoder bean).
This DelegatingPasswordEncoder tries to match stored password, retrieved from your UserDetailsService, and it assumes your password is stored with a key (prefix), like this:
{bcrypt}encodedPassword
You've registered a bean of type BCryptPasswordEncoder and you're encoding your password with it, so passwords are stored without {bcrypt} prefix (just the encoded password is stored), and when calling AuthenticationManager.authenticate() mentioned DelegatingPasswordEncoder sees null prefix and cannot find the corresponding PasswordEncoder in a map - that's what the error message is about.
So you can define a PasswordEncoder bean as a DelegatingPasswordEncoder, which, by default, uses BCryptPasswordEncoder to encode passwords.
Like this:
#Configuration
#EnableWebSecurity
#RequiredArgsConstructor
public class SecurityConfiguration {
private final AuthenticationManagerBuilder authManagerBuilder;
#Bean
public PasswordEncoder encoder() {
return PasswordEncoderFactories.createDelegatingPasswordEncoder();
}
}
That way stored passwords will have {prefix} and DaoAuthenticationProvider will be able to match passwords.
Also I advise to remove the BCryptPasswordEncoder field from your SecurityConfiguration class - you don't need it there.
Also you can stuck with bean cycle dependencies, because your UserDetailsService injects PasswordEncoder, and PasswordEncoder is defined in a configuration, where UserDetailsService is injected, so you might also need refactoring.
For example, try to extract UserDetailsService:
#Service
#RequiredArgsConstructor
#Slf4j
public class UserDetailsServiceImpl implements UserDetailsService {
private final AppUserRepo appUserRepo;
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// your logic here
return new User(username, password, authorities);
}
}
Or define a bean of this type UserDetailsService right in your SecurityConfiguration class:
#Configuration
#EnableWebSecurity
#RequiredArgsConstructor
public class SecurityConfiguration {
private final AppUserRepo appUserRepo;
// other fields
#Bean
public UserDetailsService userDetailsService() {
return username -> {
// your logic here
return new User(username, password, authorities);
};
}
}
Also you can:
instead of a custom filter create your own login endpoint, where you can check password matches using BCryptPasswordEncoder directly;
create your own AuthenticationProvider with a BCryptPasswordEncoder as a password encoder and use it in your CustomAuthenticationFilter to authenticate user.

In spring-security-core:5.0.0.RC1, the default PasswordEncoder is built as a DelegatingPasswordEncoder. When you store the users in memory, you are providing the passwords in plain text and when trying to retrieve the encoder from the DelegatingPasswordEncoder to validate the password it can't find one that matches the way in which these passwords were stored.
Use this way to create users instead.
User.withDefaultPasswordEncoder().username("user").password("user").roles("USER").build();

i am having trouble while developing web application using spring boot
i am applying spring security and having errors i dont know how to solve the error im also new at spring boot and first time using spring security my credentials are not been accessed by the compiler and having issues
this is my dao class

You have a very strange return type in your Repository class
public interface Robi_Dao_logIn extends JpaRepository<Credentials, Integer> {
#Query("select c from Credentials c where c.uname = :uname")
public Robi_Dao_logIn getbyUname(#Param("uname") String uname);
}
It should return Credentials instead of Robi_Dao_logIn.

org.hibernate.property.access.spi.PropertyAccessException: Error accessing field [private java.lang.Integer

I just tried out setting up a demo CRUD api in hibernate and I've been unable to resolve the issue with this. I've tried this with multiple versions of Hibernate but none seem to work. I keep getting the error message "Error accessing field [private java.lang.Integer com.webapp.firstwebapp.Models.UserModel.id] by reflection for persistent property [com.webapp.firstwebapp.Models.UserModel#id] : com.webapp.firstwebapp.Models.UserModel#1bc31512",

Any leads?

Okay from the Question I could see 2 things
The Inserted Items are
id, | currency_from | currency_to | conversion_multiple |port
1001 | 'USD' | 'INR' | 75. |0
1002 | 'AUD' | 'INR' | 42 |0
1003 | 'EUR' | 'INR' | 65 |0
1004 | 'POUND' | 'INR' | 51 |0
The Request http://localhost:8000/currency-exchange/from/INR/to/USD
From : INR, TO : USD
So I suspect in the below line you must have got NULL value since FROM :INR to TO: USD is not present in the table
ExchangeService exchangeValue = exchangeServiceRepository.findByFromAndTo(from, to);
So solution would be,
Check if the exchangeValue is null before processing.
(or)
Return Employee as Optional data, refer this (Above sol is simpler this for better code quality)

I'm surprised you're not receiving an exception at the start of runtime. The ExchangeServiceRepository reference is null. You need to add the #Repository annotation to the type ExchangeServiceRepository. Spring is likely unable to autowire this Bean because it's not annotated as a Repository (DAO) which at it's core is a #Component.
#Repository
public interface ExchangeServiceRepository extends JpaRepository<ExchangeService, Long>{
ExchangeService findByFromAndTo(String from, String to);
}
I don't see your main class so make sure you call #EnableJpaRepositories so that Spring Boot can pickup your repositories.

Try to use
#Value("${local.server.port}")
int port;
instead of
environment.getProperty("local.server.port")
It seems that problem is there.
In order to refute or confirm this, simply delete the line with exchangeValue.setPort(Integer.parseInt(environment.getProperty("local.server.port")));
