获取HttpServletRequest几种方法

获取方法

代码获取

先web.xml配置

<listener>
    <listener-class>
        org.springframework.web.context.request.RequestContextListener
    </listener-class>
</listener>
           

后代码获取

HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
           

spring 直接办法

public ModelAndView userLandlord(Model model, HttpServletRequest request) {
    // ...    
}
           

注解法

@Autowired
private HttpServletRequest request;
