日记拦截器的配置

虽然很简单,但是对很多人来说还是有用的..留下来以后做个足迹;

public class LogInterceptor implements HandlerInterceptor {



    private static Logger logger = LoggerFactory.getLogger(LogInterceptor.class);

    /**
     * 只做日志的记录，不做业务判断
     * @param httpServletRequest
     * @param httpServletResponse
     * @param o
     * @return
     * @throws Exception
     */
    @Override
    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
        //增加跨域支持
        httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
        httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        httpServletResponse.setHeader("Access-Control-Max-Age", "3600");
        httpServletResponse.setHeader("Access-Control-Allow-Headers", "x-requested-with");
        String loginName = httpServletRequest.getParameter("loginUserName");
        StringBuffer loggerStr = new StringBuffer();
        if(loginName!=null){
            loggerStr.append("用户："+loginName+"调用：");
        }else{
            loggerStr.append("未登录调用：");
        }
        loggerStr.append(httpServletRequest.getRequestURI()+",参数：");
        Iterator<Map.Entry<String, String[]>> it = httpServletRequest.getParameterMap().entrySet().iterator();
        while (it.hasNext()) {
            Map.Entry<String, String[]> entry = it.next();
            loggerStr.append(entry.getKey()+":"+ StringUtils.join(entry.getValue())+",");
        }
        logger.info(loggerStr.toString());
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
        String loginName = httpServletRequest.getParameter("loginUserName");
        StringBuffer loggerStr = new StringBuffer();
        if(loginName!=null){
            loggerStr.append("用户："+loginName+"调用接口：");
        }else{
            loggerStr.append("未登录调用接口：");
        }
        loggerStr.append(httpServletRequest.getRequestURI()+"成功！");
        logger.info(loggerStr.toString());
    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {

    }
}

springMVC配置文件中配置拦截器

    <!-- 配置拦截器 -->
    <mvc:interceptors>
        <!-- 日记拦截器 -->  
        <mvc:interceptor>  
            <mvc:mapping path="/**"/>
            <mvc:exclude-mapping path="/error"/>  
            <bean class="com.mimacx.interceptor.LogInterceptor"/>  
        </mvc:interceptor>
    </mvc:interceptors>
