1、添加maven依赖注解
<!--JJWT库-->
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
<version>0.6.0</version>
</dependency>2、添加登录获取token时，所需要的认证信息类LoginPara.Java
/**
* 添加登录获取token时，所需要的认证信息类LoginPara.Java
* Created by CatalpaFlat on 2017/8/29.
*/
public class LoginPara {
private String clientId;
private String userName;
private String password;
public String getClientId() {
return clientId;
}
public void setClientId(String clientId) {
this.clientId = clientId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}3、添加token返回结果类AccessToken.java
/**
* 添加token返回结果类AccessToken.java
* Created by CatalpaFlat on 2017/8/29.
*/
public class AccessToken {
private String access_token;
private String token_type;
private long expires_in;
public String getAccess_token() {
return access_token;
}
public void setAccess_token(String access_token) {
this.access_token = access_token;
}
public String getToken_type() {
return token_type;
}
public void setToken_type(String token_type) {
this.token_type = token_type;
}
public long getExpires_in() {
return expires_in;
}
public void setExpires_in(long expires_in) {
this.expires_in = expires_in;
}
}4、添加用于拼装token认证TokenObject类
/**
* Created by CatalpaFlat on 2017/8/31.
*/
@Component
public class TokenObject {
/**客户端id*/
private String clientId;
/**base64加密*/
private String base64Secret;
/**用户名*/
private String name;
/**到期时间*/
private long expiresSecond;
/**管理员名称*/
private String userName;
/**管理员id*/
private Integer aId;
/**职能*/
private String role;
/**项目名称*/
private String project;
public String getProject() {
return project;
}
public void setProject(String project) {
this.project = project;
}
public String getClientId() {
return clientId;
}
public void setClientId(String clientId) {
this.clientId = clientId;
}
public String getBase64Secret() {
return base64Secret;
}
public void setBase64Secret(String base64Secret) {
this.base64Secret = base64Secret;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public long getExpiresSecond() {
return expiresSecond;
}
public void setExpiresSecond(long expiresSecond) {
this.expiresSecond = expiresSecond;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Integer getaId() {
return aId;
}
public void setaId(Integer aId) {
this.aId = aId;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
}5、添加构造jwt及解析jwt的帮助类JwtHelper.java
/**
* 添加构造jwt及解析jwt的帮助类JwtHelper.java
* Created by CatalpaFlat on 2017/8/29.
*/
public class JwtHelper {
private static Logger logger = LoggerFactory.getLogger(JwtHelper.class);
/**
* 校验Token
* @param jwt
* @param httpRequest
* @return
*/
public static int checkToken(String jwt, HttpServletRequest httpRequest){
if (!StringUtils.isBlank(jwt)){
if (jwt.split("\.").length==3) {
logger.info("jwt:" + jwt);
String[] split = jwt.split("\.");
String content = split[1];
String s = Base64Codec.BASE64URL.decodeToString(content);
logger.info("s:" + s);
String sign = split[2];
logger.info("sign:" + sign);
JSONObject jsonObject1 = JSONObject.fromObject(s);
long nowMillis = System.currentTimeMillis();
Date now = new Date(nowMillis);
long expiresSecond = (long) jsonObject1.get("expiresSecond");
//判断是否过期
if(now.getTime()>expiresSecond)
return 2;
TokenObject o = (TokenObject) JSONObject.toBean(jsonObject1, TokenObject.class);
if (o!=null){
String project = o.getProject();
if (!StaticInfo.PROJECT.equals(project))
return 0;
}
String jwtByStr = createJWTByObj(o);
String s2 = jwtByStr.split("\.")[2];
logger.info("s2:" + s2);
if (sign.equals(s2)) {
return 1;
} else
return 0;
}
}
return 0;
}
/**
* 获取用户id
* @param jwt
* @return
*/
public static int getIdByJWT(String jwt){
if (!StringUtils.isBlank(jwt)) {
if (jwt.split("\.").length == 3) {
logger.info("jwt:" + jwt);
String[] split = jwt.split("\.");
String content = split[1];
String s = Base64Codec.BASE64URL.decodeToString(content);
JSONObject jsonObject1 = JSONObject.fromObject(s);
TokenObject o = (TokenObject) JSONObject.toBean(jsonObject1, TokenObject.class);
return o.getaId();
}
}
return 0;
}
/**
* 获取客户信息
* @param request
* @return
* @throws CustomException
*/
public static int getIdByRequest(HttpServletRequest request) throws CustomException {
int i = 0;
String auth = request.getHeader("Authorization");
if ((auth != null) && (auth.length() > 6)) {
String HeadStr = auth.substring(0, 5).toLowerCase();
if (HeadStr.compareTo("basic") == 0) {
auth = auth.substring(6, auth.length());
i = JwtHelper.getIdByJWT(auth);
}
}
if (i==0)
throw new CustomException(ResultEnum.PERMISSION_DENIED);
return i;
}
public static String createJWTByObj(TokenObject tokenObject) {
JSONObject jsonObject = JSONObject.fromObject(tokenObject);
SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS256;
long nowMillis = System.currentTimeMillis();
Date now = new Date(nowMillis);
//生成签名密钥
byte[] apiKeySecretBytes = DatatypeConverter.parseBase64Binary(tokenObject.getBase64Secret());
Key signingKey = new SecretKeySpec(apiKeySecretBytes, signatureAlgorithm.getJcaName());
//添加构成JWT的参数
JwtBuilder builder = Jwts.builder().setHeaderParam("typ", "JWT")
.setHeaderParam("alg", "HS256")
.setPayload(jsonObject.toString())
.signWith(signatureAlgorithm, signingKey);
//生成JWT
return builder.compact();
}
} 6、添加token过滤器
（如果请求的Header中存在Authorization: Basic 头信息，且用户名密码正确，则继续原来的请求，否则返回没有权限的错误信息）
/**
* 如果请求的Header中存在Authorization: Basic 头信息，且用户名密码正确，则继续原来的请求，否则返回没有权限的错误信息

//1.检测当前是否需要重新登录

//2.检测请求同token信息
ResultEnum resultStatusCode = checkHTTPBasicAuthorize(request);

toResponse((HttpServletResponse) response, 2,(HttpServletRequest) request);
return;
}else if (resultStatusCode.equals(ResultEnum.PERMISSION_DENIED)){//权限不够
toResponse((HttpServletResponse) response, 0,(HttpServletRequest) request);
return;
}
logger.info("后台token过滤器检测通过");
chain.doFilter(request, response);
}
/**

}

}7、测试token
