无法解析配置属性 'spring.session.store-type'

非常抱歉，您似乎遗漏了一些必要的依赖项。以下是添加这些依赖项并修复问题后的代码示例：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HaloSpringApplication {

    public static void main(String[] args) {
        SpringApplication.run(HaloSpringApplication.class, args);
    }
}

此外，为了正确解析配置属性，您还可能需要在应用程序启动时运行以下脚本（如果是通过JavaFX创建的应用程序）：

ApplicationListener<ConfigPropertiesChangedEvent> configPropertiesChangedListener = new ApplicationListener<ConfigPropertiesChangedEvent>() {
    @Override
    public void onConfigPropertiesChanged(ConfigPropertiesChangedEvent event) {
        String springSessionStoreType = event.getProperty("spring.session.store-type");
        System.out.println(springSessionStoreType);
    }
};

@Component
public class SpringSessionFactoryConfigProperties implements ConfigPropertiesChangedListener {

    @Override
    public void onConfigPropertiesChanged(ConfigPropertiesChangedEvent event) {
        String springSessionStoreType = event.getProperty("spring.session.store-type");
        if (springSessionStoreType != null && springSessionStoreType.equalsIgnoreCase("jdbc")) {
            System.out.println("Using JDBC store type.");
        } else if (springSessionStoreType != null && springSessionStoreType.equalsIgnoreCase("jwt")) {
            System.out.println("Using JWT store type.");
        } else {
            System.out.println("Invalid store type.");
        }
    }

}

将这两个类放在同一个包内（例如src/main/java/com/example/halospring），然后在application.properties文件中添加它们作为子类：

spring.session.jdbccleanup-cron=0
spring.session.store-type=jdbc
spring.session.timeout=180s
spring.app.name=haloSpring
spring.web.server.port=8081

这应该能解决您的问题，并使Spring Session持久化存储数据。如果您在应用启动后仍然遇到问题，请提供更多细节，以便我能更好地为您提供支持。
