获取ip地址

public class IpUtils {private IpUtils() {}/*** 获取请求ip地址** @return {@link String}*/public static String getIpAddress() {HttpServletRequest request = RequestContextHolderUtils.getRequest();String ip = request.getHeader("x-forwarded-for");if (ip == null || ip.isEmpty() || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("Proxy-Client-IP");}if (ip == null || ip.isEmpty() || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("X-Forwarded-For");}if (ip == null || ip.isEmpty() || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("WL-Proxy-Client-IP");}if (ip == null || ip.isEmpty() || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("X-Real-IP");}if (ip == null || ip.isEmpty() || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}if ("0:0:0:0:0:0:0:1".equals(ip)) {ip = "127.0.0.1";}if (ip.contains(",")) {ip = ip.split(",")[0];}return ip;}
}

请求上下文相关

• 获取HttpServletRequest、HttpServletResponse、HttpSession、ServletContext等对象

public class RequestContextHolderUtils {/*** 获取HttpServletRequest请求对象** @return {@link HttpServletRequest}*/public static HttpServletRequest getRequest() {return getRequestAttributes().getRequest();}/*** 获取HttpServletResponse响应对象** @return {@link HttpServletResponse}*/public static HttpServletResponse getResponse() {return getRequestAttributes().getResponse();}/*** 获得会话** @return {@link HttpSession}*/public static HttpSession getSession() {return getRequest().getSession();}/*** 设置会话属性** @param name  名字* @param value 值*/public static void setSessionAttribute(String name, Object value) {getSession().setAttribute(name, value);}/*** 获得会话属性** @param name 名字* @return {@link Object}*/public static Object getSessionAttribute(String name) {return getSession().getAttribute(name);}/*** servlet容器请求属性** @return {@link ServletRequestAttributes}*/public static ServletRequestAttributes getRequestAttributes() {return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes());}/*** 得到servlet上下文** @return {@link ServletContext}*/public static ServletContext getServletContext() {return Objects.requireNonNull(ContextLoader.getCurrentWebApplicationContext()).getServletContext();}
}

Spring上下文获取Bean对象

@Component
public class SpringContextUtils implements ApplicationContextAware {/*** 上下文对象实例* -- GETTER --*  获取applicationContext*/@Getterprivate static ApplicationContext applicationContext;@Override@Autowiredpublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {SpringContextUtils.applicationContext = applicationContext;}/*** 通过name获取 Bean.*/public static Object getBean(String name) {return getApplicationContext().getBean(name);}/*** 通过class获取Bean.*/public static <T> T getBean(Class<T> clazz) {return getApplicationContext().getBean(clazz);}/*** 通过name,以及Clazz返回指定的Bean*/public static <T> T getBean(String name, Class<T> clazz) {return getApplicationContext().getBean(name, clazz);}
