在Service层或普通类中获取request对象_service 获取request-优快云博客

本文详细介绍了如何在SpringMVC框架中配置监听器并直接或间接获取HttpServletRequest对象，以及在Webservice环境中通过不同方式获取request对象的方法，包括使用WebServiceContext、WebServiceContextImpl和PhaseInterceptorChain。

SpringMVC

首先要在 web.xml中配置监听

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

在Service层可以直接注入

@Autowired  
private HttpServletRequest request;

普通类中也可以这样获取request对象

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

Webservice

我这边重新整理一下

配置注入方式

@Resource
private WebServiceContext webServiceContext;

//获取request对象
MessageContext mc = webServiceContext.getMessageContext();
HttpServletRequest request = (HttpServletRequest) (mc.get(MessageContext.SERVLET_REQUEST));

通过new WebServiceContextImpl() 获取WebService上下文

WebServiceContext context = new WebServiceContextImpl();
MessageContext ctx = context.getMessageContext();
HttpServletRequest request = (HttpServletRequest) ctx.get(AbstractHTTPDestination.HTTP_REQUEST);

这种方式获取可能靠谱一点（如果其他方式获取的context为null，使用这种方式应该可以获取到）

Message message = PhaseInterceptorChain.getCurrentMessage();
HttpServletRequest request = (HttpServletRequest) message.get(AbstractHTTPDestination.HTTP_REQUEST);

这里我也附带一个获取客户端IP的方法，项目一直在用

    /**
     * 获得访问客户端的ip地址，这里对null和0:0:0:0:0:0:0:1做了处理
     * @return ip地址
     */
public static String getRemoteIp(HttpServletRequest request){
        String ip = request.getHeader("x-forwarded-for");
        if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)){
            ip = request.getHeader("Proxy-Client-IP");
        }
        if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)){
            ip = request.getHeader("WL-Proxy-Client-IP");
        }
        if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)){
            ip = request.getRemoteAddr();
        }
        if(ip == null){
            ip = "0.0.0.0";
        }
        return "0:0:0:0:0:0:0:1".equals(ip)?"127.0.0.1":ip;
    }
