在spring集成流程中如何在threadlocal中注入变量

public class ThreadLocalVariableHolder {
    private static ThreadLocal<String> threadLocalVariable = new ThreadLocal<>();

    public static String getThreadLocalVariable() {
        return threadLocalVariable.get();
    }

    public static void setThreadLocalVariable(String value) {
        threadLocalVariable.set(value);
    }
}

public class MyInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String value = // 获取要注入的变量值
        ThreadLocalVariableHolder.setThreadLocalVariable(value);
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        // 清除ThreadLocal变量，避免内存泄漏
        ThreadLocalVariableHolder.setThreadLocalVariable(null);
    }
}

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    @Autowired
    private MyInterceptor myInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(myInterceptor);
    }
}
