如何在Spring Boot项目中设置web.xml JNDI <env-entry>的等价物？

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import org.springframework.boot.web.servlet.ServletContextInitializer;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JndiInitializer implements ServletContextInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        servletContext.setInitParameter("myEnvEntry", "myValue");
        // 设置其他的 JNDI <env-entry>
    }
}

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

@SpringBootApplication
@ServletComponentScan
public class MyApplication {

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