How to set up Spring Security SecurityContextHolder strategy?

You can set the environment variable spring.security.strategy to MODE_INHERITABLETHREADLOCAL. You could also have a simple bean that during your web applications startup calls SecurityContextHolder.setStrategyName(SecurityContextHolder.MODE_INHERITABLETHREADLOCAL) and initialize that value in your context configuration file.

The java config for @viator 's answer if it helps you.

@Bean
public MethodInvokingFactoryBean methodInvokingFactoryBean() {
    MethodInvokingFactoryBean methodInvokingFactoryBean = new MethodInvokingFactoryBean();
    methodInvokingFactoryBean.setTargetClass(SecurityContextHolder.class);
    methodInvokingFactoryBean.setTargetMethod("setStrategyName");
    methodInvokingFactoryBean.setArguments(new String[]{SecurityContextHolder.MODE_INHERITABLETHREADLOCAL});
    return methodInvokingFactoryBean;
}
