这篇文章主要介绍了springboot封装JsonUtil,CookieUtil工具类过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
JsonUtil
public class JsonUtil {
private static ObjectMapper objectMapper = new ObjectMapper();
public static String objectToString(Object object) throws JsonProcessingException {
return objectMapper.writeValueAsString(object);
}
public static <T> T stringToObject(String json,Class<T> object) throws IOException {
return objectMapper.readValue(json,object);
}
}
CookieUtil
public class CookieUtil {
public static String getCookie(HttpServletRequest request, String cookieName){
Cookie[] cookies = request.getCookies();
if(cookies != null){
for(Cookie cookie : cookies){
if(cookie.getName().equals(cookieName)){
return cookie.getValue();
}
}
}
return null;
}
public static void setCookie(HttpServletResponse response, String cookieName, String value,int cookieMaxAge){
Cookie cookie = new Cookie(cookieName,value);
cookie.setPath("/");
cookie.setMaxAge(cookieMaxAge);
response.addCookie(cookie);
}
public static void deleteCookie(HttpServletResponse response, String cookieName){
setCookie(response,cookieName,null,0);
}
}
