ProGuard will make Spring Bean name conflict

I tried to use Spring definition.getBeanClassName() naming rules, but it didn’t work. Is it too much trouble if you want to manually set the name of each bean on the annotation? Can ProGuard provide the function of not repeating the class name? I haven’t found it yet.

#PostContruct giving NullPointerException during server startup

I am getting Null Pointer Exception during server startup in the first line.
public class DefaultAreaPostalCodeService extends AbstractBusinessService implements AreaPostalCodeService {
private Map<String,List<PostalCodeData>> suburbMap;
#PostConstruct
#Transactional
public void initialize() {
List<AreaPostalCodeModel> postalCodes = areaPostalCodeDao.getAllAreaPostalCodes();
populateSuburbMap(postalCodes);
}
}
<bean id="areaPostalCodeService"
class="za.co.testro.core.address.impl.DefaultAreaPostalCodeService" parent="abstractBusinessService">
<property name="areaPostalCodeDao" ref="areaPostalCodeDao" />
</bean>
I simply want to populate the suburbMap at server startup so that I can use it later.

it is very normal to have such behavior, because #PostConstruct method will be called before injecting areaPostalCodeDao bean into areaPostalCodeDao property wich is null (for that moment).
There are 4 ways to run some code on bean initializing, but each way succeed in a specific step.
Spring bean setup lifecycle:
standard constructor
#PostConstruct
#Override afterPropertiesSet() from InitializingBean interface
init-method
So in your case you should do as above :
import org.springframework.beans.factory.InitializingBean;
public class DefaultAreaPostalCodeService extends AbstractBusinessService implements AreaPostalCodeService,InitializingBean {
private Map<String,List<PostalCodeData>> suburbMap;
#Override
#Transactional
public void afterPropertiesSet() {
List<AreaPostalCodeModel> postalCodes = areaPostalCodeDao.getAllAreaPostalCodes();
populateSuburbMap(postalCodes);
}
}

A possible solution, maybe not specifically for this case but could help others, is to call the code from the view, call it on first glance. The code would be something like:
In XHTML
<f:metadata>
<f:viewAction action="#{myUI.myVoid()}"/>
</f:metadata>

HikariPool-1 - jdbcUrl is required with driverClassName

I went back to programming my old program https://github.com/JonkiPro/REST-Web-Services. I've updated Spring Boot from version 15.6 to version 2.0.0. I have encountered many problems with compilation, but I can not deal with one. Well, during compilation, he throws me in the console

I've never had such a mistake. I do not know what it means completely. My properties for the base look like this
spring:
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql:database
username: root
password: root
schema: classpath:/db/init/schema.sql
I do not know how to deal with this error. I've been programming quite a long time, but for the first time I'm meeting the concept of hikari. I'm using a Tomcat(in Spring Boot) server and a PostgreSQL database.

I had the same issue in another context.
From the 79. Data Access - Configure a Custom DataSource
if you happen to have Hikari on the classpath, this basic setup does not work, because Hikari has no url property (but does have a jdbcUrl property)
Hikari is the default pool in spring boot 2.
so you can replace the config
url: jdbc:postgresql:database -> jdbc-url: jdbc:postgresql:database
or you can keep the config but you need to define another Bean to handle the mapping (aliases)
#Bean
#Primary
#ConfigurationProperties("app.datasource")
public DataSourceProperties dataSourceProperties() {
return new DataSourceProperties();
}
#Bean
#ConfigurationProperties("app.datasource")
public DataSource dataSource(DataSourceProperties properties) {
return properties.initializeDataSourceBuilder().
.build();
}

Either remove spring.datasource.driver-class-name property or rename the spring.datasource.url property to spring.datasource.jdbc-url.
This is reported in your error:
java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName
First option looks cleaner and Spring Boot will figure out the default driver class name based on the spring.datasource.url property value (see org.springframework.boot.jdbc.DatabaseDriver class if you want to debug this).

Multiple liquibase configurations in spring boot

I have spring boot application which use 2 databases. I defined 2 configurations providing specified datasources. I want to have that datasources managed separately by liquibase. I defined 2 separated changelog files.
The problem is that I can't define 2 separate beans for liquibase.
Here are my config classes:
...
public class CCSConfiguration {
...
#Bean
#ConfigurationProperties("ccs.liquibase")
public LiquibaseProperties ccsLiquibaseProperties() {
return new LiquibaseProperties();
}
#Bean
public SpringLiquibase ccsLiquibase(LiquibaseProperties liquibaseProperties) {
...
}
...
}
...
public class CCAConfiguration {
...
#ConfigurationProperties("cca.liquibase")
public LiquibaseProperties ccaLiquibaseProperties() {
return new LiquibaseProperties();
}
#Bean
public SpringLiquibase ccaLiquibase(LiquibaseProperties liquibaseProperties) {
...
}
...
}
And properties:
cca:
liquibase:
change-log: classpath:config/liquibase/cca/master.xml
ccs:
liquibase:
change-log: classpath:config/liquibase/ccs/master.xml
With this config i get following error while running appliction:

Description:
A component required a bean named 'liquibase' that could not be found.
Action:
Consider defining a bean named 'liquibase' in your configuration.
So, is it possible to define multiple liquibase beans for different datasources?

there are two options:
you define a bean named liquibase to let spring-boot integrated process to update your schema on you first DS. You have to handle the second one by hand
you disable liquibase automatic update at startup with
enabled: false
and define your way DS and liquibase beans to update your two databases

My guess is that you have a searchable property of type org.bson.types.ObjectId. This is not a type that the searchable plugin natively knows how to index, so you have to define a converter for it.
