[Solved]-"error processing condition on org.springframework.boot.autoconfigure.context.propertyplaceholderautoconfiguration.propertysourcesplaceholderconfigurer"

To resolve the error java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.jdbc.JndiDataSourceAutoConfiguration, follow these steps:

1. Check your Spring Boot application's configuration files, particularly application.properties or application.yml, to ensure that the JNDI datasource configuration is correctly specified.
2. Verify that the JNDI name configured in your Spring Boot application matches the JNDI name defined in your application server (e.g., Tomcat, Wildfly).
3. Ensure that the JNDI datasource is properly configured and available in your application server. You may need to consult your application server's documentation for guidance on setting up JNDI datasources.
4. If you are using Spring Boot's auto-configuration feature, make sure that there are no conflicts or misconfigurations in your project dependencies that could interfere with the JNDI datasource auto-configuration.
5. Check for any custom conditions or properties that might be affecting the auto-configuration of the JNDI datasource in your application.

To address the dependency issue, it's advisable not to specify the version explicitly unless absolutely necessary, as it can lead to conflicts with other dependencies. This is one of the reasons why Spring Boot is favored, as it handles dependencies and their compatibility seamlessly.

When opting for Spring Boot, relying on 'spring-boot-starter' dependencies is generally recommended. These starters include predefined configurations that simplify the setup process and ensure compatibility.

Regarding the choice between 'spring-boot-actuator' and 'spring-boot-starter-actuator', it's important to understand their differences:

• spring-boot-actuator: This is the core actuator module, providing various management and monitoring endpoints for your application. It's suitable for more advanced customization and control.
• spring-boot-starter-actuator: This is a starter module that includes 'spring-boot-actuator' along with necessary dependencies, making it easier to incorporate actuator functionality into your project.

Now, let's address the sample pom.xml:

        
            <org.springframework.boot>
                <spring-boot-starter-parent>
                    <version>2.1.8.RELEASE</version>
                </spring-boot-starter-parent>
            </org.springframework.boot>

            <dependencies>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-actuator</artifactId>
                    <scope>provided</scope>
                </dependency>
            </dependencies>
        
    

In this configuration, the project inherits the version management from 'spring-boot-starter-parent', which is a common practice in Spring Boot projects. The 'spring-boot-starter-actuator' dependency is included with a scope of 'provided', indicating that the actuator functionality will be provided by the runtime environment, such as Spring Boot itself.
