在分布式环境中，如何支持PC、APP（ios、android）等多端的会话共享，这也是所有公司都需要的解决方案，用传统的session方式来解决，我想已经out了，我们是否可以找一个通用的方案，比如用传统cas来实现多系统之间的sso单点登录或使用oauth的第三方登录方案?
今天给大家简单讲解一下使用spring拦截器Interceptor机制、jwt认证方式、redis分布式缓存实现sso单点登录，闲话少说，直接把步骤记录下来分享给大家：
1. 引入jwt的相关jar包，在项目pom.xml中引入：
Java代码
<dependency>
<groupId>com.auth0</groupId>
<artifactId>java-jwt</artifactId>
<version>2.2.0</version>
</dependency>
2. 拦截器配置：
Java代码
<mvc:interceptor>
<mvc:mapping path="${adminPath}/**" />
<mvc:exclude-mapping path="${adminPath}/rest/login"/>
<bean class="com.ml.honghu.interceptor.LoginInterceptor" />
</mvc:interceptor>
我这里简单配置了要拦截的url和过滤的url（这个根据自己项目来定）
3. 编写jwt的加密或者解密工具类：
Java代码
public class JWT {
private static final String SECRET = "HONGHUJWT1234567890QWERTYUIOPASDFGHJKLZXCVBNM";
private static final String EXP = "exp";
private static final String PAYLOAD = "payload";
//加密
public static <T> String sign(T object, long maxAge) {
try {
final JWTSigner signer = new JWTSigner(SECRET);
final Map<String, Object> claims = new HashMap<String, Object>();
ObjectMapper mapper = new ObjectMapper();
String jsonString = mapper.writeValueAsString(object);
claims.put(PAYLOAD, jsonString);
claims.put(EXP, System.currentTimeMillis() + maxAge);
return signer.sign(claims);
} catch(Exception e) {
return null;
}
}
//解密
public static<T> T unsign(String jwt, Class<T> classT) {
final JWTVerifier verifier = new JWTVerifier(SECRET);
try {
final Map<String,Object> claims= verifier.verify(jwt);
if (claims.containsKey(EXP) && claims.containsKey(PAYLOAD)) {
String json = (String)claims.get(PAYLOAD);
ObjectMapper objectMapper = new ObjectMapper();
return objectMapper.readValue(json, classT);
}
return null;
} catch (Exception e) {
return null;
}
}
}
这个加密工具类是我从网上找的，如果各位要修改，可以按照自己业务修改即可。
4. 创建Login.java对象，用来进行jwt的加密或者解密：
Java代码
12bb0
public class Login implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1899232511233819216L;
/**
* 用户id
*/
private String uid;
/**
* 登录用户名
*/
private String loginName;
/**
* 登录密码
*/
private String password;
public Login(){
super();
}
public Login(String uid, String loginName, String password){
this.uid = uid;
this.loginName = loginName;
this.password = password;
}
public String getUid() {
return uid;
}
public void setUid(String uid) {
this.uid = uid;
}
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
5. 定义RedisLogin对象，用来通过uid往redis进行user对象存储：
Java代码
public class RedisLogin implements Serializable{
/**
*
*/
private static final long serialVersionUID = 8116817810829835862L;
/**
* 用户id
*/
private String uid;
/**
* jwt生成的token信息
*/
private String token;
/**
* 登录或刷新应用的时间
*/
private long refTime;
public RedisLogin(){
}
public RedisLogin(String uid, String token, long refTime){
this.uid = uid;
this.token = token;
this.refTime = refTime;
}
public String getUid() {
return uid;
}
public void setUid(String uid) {
this.uid = uid;
}
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
public long getRefTime() {
return refTime;
}
public void setRefTime(long refTime) {
this.refTime = refTime;
}
}
6. 编写LoginInterceptor.java拦截器
Java代码
public class LoginInterceptor implements HandlerInterceptor{
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
PrintWriter writer = null;
HandlerMethod method = null;
try {
method = (HandlerMethod) handler;
} catch (Exception e) {
writer = response.getWriter();
ResponseVO responseVO = ResponseCode.buildEnumResponseVO(ResponseCode.REQUEST_URL_NOT_SERVICE, false);
responseMessage(response, writer, responseVO);
return false;
}
IsLogin isLogin = method.getMethodAnnotation(IsLogin.class);
if(null == isLogin){
return true;
}
response.setCharacterEncoding("utf-8");
String token = request.getHeader("token");
String uid = request.getHeader("uid");
//token不存在
if(StringUtils.isEmpty(token)) {
writer = response.getWriter();
ResponseVO responseVO = LoginResponseCode.buildEnumResponseVO(LoginResponseCode.LOGIN_TOKEN_NOT_NULL, false);
responseMessage(response, writer, responseVO);
return false;
}
if(StringUtils.isEmpty(uid)){
writer = response.getWriter();
ResponseVO responseVO = LoginResponseCode.buildEnumResponseVO(LoginResponseCode.USERID_NOT_NULL, false);
responseMessage(response, writer, responseVO);
return false;
}
Login login = JWT.unsign(token, Login.class);
//解密token后的loginId与用户传来的loginId判断是否一致
if(null == login || !StringUtils.equals(login.getUid(), uid)){
writer = response.getWriter();
ResponseVO responseVO = LoginResponseCode.buildEnumResponseVO(LoginResponseCode.USERID_NOT_UNAUTHORIZED, false);
responseMessage(response, writer, responseVO);
return false;
}
//验证登录时间
RedisLogin redisLogin = (RedisLogin)JedisUtils.getObject(uid);
if(null == redisLogin){
writer = response.getWriter();
ResponseVO responseVO = LoginResponseCode.buildEnumResponseVO(LoginResponseCode.RESPONSE_CODE_UNLOGIN_ERROR, false);
responseMessage(response, writer, responseVO);
return false;
}
if(!StringUtils.equals(token, redisLogin.getToken())){
writer = response.getWriter();
ResponseVO responseVO = LoginResponseCode.buildEnumResponseVO(LoginResponseCode.USERID_NOT_UNAUTHORIZED, false);
responseMessage(response, writer, responseVO);
return false;
}
//系统时间>有效期（说明已经超过有效期）
if (System.currentTimeMillis() > redisLogin.getRefTime()) {
writer = response.getWriter();
ResponseVO responseVO = LoginResponseCode.buildEnumResponseVO(LoginResponseCode.LOGIN_TIME_EXP, false);
responseMessage(response, writer, responseVO);
return false;
}
//重新刷新有效期
redisLogin = new RedisLogin(uid, token, System.currentTimeMillis() + 60L* 1000L* 30L);
JedisUtils.setObject(uid , redisLogin, 360000000);
return true;
}
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
}
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
throws Exception {
}
private void responseMessage(HttpServletResponse response, PrintWriter out, ResponseVO responseVO) {
response.setContentType("application/json; charset=utf-8");
JSONObject result = new JSONObject();
result.put("result", responseVO);
out.print(result);
out.flush();
out.close();
}
}
7. 定义异常的LoginResponseCode
Java代码
public enum LoginResponseCode {
USERID_NOT_NULL(3001,"用户id不能为空."),
LOGIN_TOKEN_NOT_NULL(3002,"登录token不能为空."),
USERID_NOT_UNAUTHORIZED(3003, "用户token或ID验证不通过"),
RESPONSE_CODE_UNLOGIN_ERROR(421, "未登录异常"),
LOGIN_TIME_EXP(3004, "登录时间超长，请重新登录");
// 成员变量
private int code; //状态码
private String message; //返回消息
// 构造方法
private LoginResponseCode(int code,String message) {
this.code = code;
this.message = message;
}
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public static ResponseVO buildEnumResponseVO(LoginResponseCode responseCode, Object data) {
return new ResponseVO(responseCode.getCode(),responseCode.getMessage(),data);
}
public static Map<String, Object> buildReturnMap(LoginResponseCode responseCode, Object data) {
Map<String, Object> map = new HashMap<String, Object>();
map.put("code", responseCode.getCode());
map.put("message", responseCode.getMessage());
map.put("data", data);
return map;
}
}
8. 编写统一sso单点登录接口：
Java代码
@RequestMapping(value = "/login", method = RequestMethod.POST)
public Map<String, Object> login(@RequestBody JSONObject json){
String loginName = json.optString("loginName");
String password = json.optString("password");
//校验用户名不能为空
if(StringUtils.isEmpty(loginName)){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_NAME_IS_NOT_EMPTY, null);
}
//校验用户密码不能为空
if(StringUtils.isEmpty(password)){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_PWD_CAN_NOT_BE_EMPTY, null);
}
//根据用户名查询数据库用户信息
User user = systemService.getBaseUserByLoginName(loginName);
//用户名或密码不正确
if(null == user){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_VALIDATE_NO_SUCCESS, false);
}
boolean isValidate = systemService.validatePassword(password, user.getPassword());
if(!isValidate){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_VALIDATE_NO_SUCCESS, false);
}
if(isValidate){
//HttpSession session =request.getSession(false);
Login login = new Login(user.getId(), user.getLoginName(), user.getPassword());
//给用户jwt加密生成token
String token = JWT.sign(login, 60L* 1000L* 30L);
Map<String,Object> result =new HashMap<String,Object>();
result.put("loginToken", token);
result.put("userId", user.getId());
result.put("user", user);
//保存用户信息到session
//session.setAttribute(user.getId() + "@@" + token, user);
//重建用户信息
this.rebuildLoginUser(user.getId(), token);
return ResponseCode.buildReturnMap(ResponseCode.RESPONSE_CODE_LOGIN_SUCCESS, result);
}
return ResponseCode.buildReturnMap(ResponseCode.USER_LOGIN_PWD_ERROR, false);
}
9. 测试sso单点登录：
返回结果集：
Java代码
{
"message": "用户登录成功",
"data": {
"loginToken": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE1MDkzODA1OTU0NTksInBheWxvYWQiOiJ7XCJ1aWRcIjpcIjExXCIsXCJsb2dpbk5hbWVcIjpcImFkbWluXCIsXCJwYXNzd29yZFwiOlwiZjU0NGQxM2QyY2EwNDU5ZGQ0ZTU1NzVjNmZkYWIzMzM0MzE1MWFlZjgwYmE5ZTNiN2U1ZjM2MzJcIn0ifQ.56L60WtxHXSu9vNs6XsWy5zbmc3kP_IWG1YpReK50DM",

map.put("message", responseCode.getMessage());
map.put("data", data);
return map;
}
}
public enum LoginResponseCode {
USERID_NOT_NULL(3001,"用户id不能为空."),
LOGIN_TOKEN_NOT_NULL(3002,"登录token不能为空."),
USERID_NOT_UNAUTHORIZED(3003, "用户token或ID验证不通过"),
RESPONSE_CODE_UNLOGIN_ERROR(421, "未登录异常"),
LOGIN_TIME_EXP(3004, "登录时间超长，请重新登录");
// 成员变量
private int code; //状态码
private String message; //返回消息
// 构造方法
private LoginResponseCode(int code,String message) {
this.code = code;
this.message = message;
}
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public static ResponseVO buildEnumResponseVO(LoginResponseCode responseCode, Object data) {
return new ResponseVO(responseCode.getCode(),responseCode.getMessage(),data);
}
public static Map<String, Object> buildReturnMap(LoginResponseCode responseCode, Object data) {
Map<String, Object> map = new HashMap<String, Object>();
map.put("code", responseCode.getCode());
map.put("message", responseCode.getMessage());
map.put("data", data);
return map;
}
}8. 编写统一sso单点登录接口：
Java代码
@RequestMapping(value = "/login", method = RequestMethod.POST)
public Map<String, Object> login(@RequestBody JSONObject json){
String loginName = json.optString("loginName");
String password = json.optString("password");
//校验用户名不能为空
if(StringUtils.isEmpty(loginName)){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_NAME_IS_NOT_EMPTY, null);
}
//校验用户密码不能为空
if(StringUtils.isEmpty(password)){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_PWD_CAN_NOT_BE_EMPTY, null);
}
//根据用户名查询数据库用户信息
User user = systemService.getBaseUserByLoginName(loginName);
//用户名或密码不正确
if(null == user){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_VALIDATE_NO_SUCCESS, false);
}
boolean isValidate = systemService.validatePassword(password, user.getPassword());
if(!isValidate){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_VALIDATE_NO_SUCCESS, false);
}
if(isValidate){
//HttpSession session =request.getSession(false);
Login login = new Login(user.getId(), user.getLoginName(), user.getPassword());
//给用户jwt加密生成token
String token = JWT.sign(login, 60L* 1000L* 30L);
Map<String,Object> result =new HashMap<String,Object>();
result.put("loginToken", token);
result.put("userId", user.getId());
result.put("user", user);
//保存用户信息到session
//session.setAttribute(user.getId() + "@@" + token, user);
//重建用户信息
this.rebuildLoginUser(user.getId(), token);
return ResponseCode.buildReturnMap(ResponseCode.RESPONSE_CODE_LOGIN_SUCCESS, result);
}
return ResponseCode.buildReturnMap(ResponseCode.USER_LOGIN_PWD_ERROR, false);
}
@RequestMapping(value = "/login", method = RequestMethod.POST)
public Map<String, Object> login(@RequestBody JSONObject json){
String loginName = json.optString("loginName");
String password = json.optString("password");
//校验用户名不能为空
if(StringUtils.isEmpty(loginName)){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_NAME_IS_NOT_EMPTY, null);
}
//校验用户密码不能为空
if(StringUtils.isEmpty(password)){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_PWD_CAN_NOT_BE_EMPTY, null);
}
//根据用户名查询数据库用户信息
User user = systemService.getBaseUserByLoginName(loginName);
//用户名或密码不正确
if(null == user){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_VALIDATE_NO_SUCCESS, false);
}
boolean isValidate = systemService.validatePassword(password, user.getPassword());
if(!isValidate){
return MemberResponseCode.buildReturnMap(MemberResponseCode.RESPONSE_CODE_USER_VALIDATE_NO_SUCCESS, false);
}
if(isValidate){
//HttpSession session =request.getSession(false);
Login login = new Login(user.getId(), user.getLoginName(), user.getPassword());
//给用户jwt加密生成token
String token = JWT.sign(login, 60L* 1000L* 30L);
Map<String,Object> result =new HashMap<String,Object>();
result.put("loginToken", token);
result.put("userId", user.getId());
result.put("user", user);
//保存用户信息到session
//session.setAttribute(user.getId() + "@@" + token, user);
//重建用户信息
this.rebuildLoginUser(user.getId(), token);
return ResponseCode.buildReturnMap(ResponseCode.RESPONSE_CODE_LOGIN_SUCCESS, result);
}
return ResponseCode.buildReturnMap(ResponseCode.USER_LOGIN_PWD_ERROR, false);
}9. 测试sso单点登录：
返回结果集：
Java代码
