springboot jwt实现登录
m0_54861649 人气:0公司开发的系统原先的用户信息是基于shiro session 进行管理，但是session不适用于app端，并且服务器重启后需要重新登录。需要改造将shiro和jwt进行整合，实现通过token登录。
1.导入依赖
<dependency>
<groupId>com.auth0</groupId>
<artifactId>java-jwt</artifactId>
<version>3.2.0</version>
</dependency>2.JWTToken 替换 Shiro 原生 Token
import org.apache.shiro.authc.AuthenticationToken;
public class JWTToken implements AuthenticationToken {
// 密钥
private String token;
public JWTToken(String token) {
this.token = token;
}
@Override
public Object getPrincipal() {
return token;
public Object getCredentials() {
}3.JWT token 工具类，提供JWT生成、校验、获取token存储的信息
import com.auth0.jwt.JWT;
import com.auth0.jwt.JWTVerifier;
import com.auth0.jwt.algorithms.Algorithm;
import com.auth0.jwt.exceptions.JWTDecodeException;
import com.auth0.jwt.interfaces.DecodedJWT;
import com.hxkg.datafusion.controller.FlieController;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.io.UnsupportedEncodingException;
import java.util.Date;
/**
* JWT token 工具类
*
* @author yangfeng
* @Date 2019-09-17
*/
@ConfigurationProperties(prefix = "jwt")
@Component
public class JWTUtil {
private static Logger LOG = LoggerFactory.getLogger(FlieController.class);
//过期时间
private static Long expire;
// 秘钥
private static String secret;
/**
* 校验token是否正确
*
* @param token 密钥
* @return 是否正确
*/
public static boolean verify(String token, String userName) {
try {
//根据密码生成JWT效验器
Algorithm algorithm = Algorithm.HMAC256(secret);
JWTVerifier verifier = JWT.require(algorithm)
.withClaim("userName", userName)
.build();
//效验TOKEN
verifier.verify(token);
return true;
} catch (UnsupportedEncodingException e) {
return false;
}
}
* 获得token中的信息无需secret解密也能获得
* @return token中包含的用户名
public static String getUsername(String token) {
DecodedJWT jwt = JWT.decode(token);
return jwt.getClaim("userName").asString();
} catch (JWTDecodeException e) {
return null;
* 获取用户id
* @param token
* @return
public static String getUserId(String token) {
return jwt.getClaim("userId").asString();
* 生成签名
* @param userName 用户名
* @param userId
* @return 加密的token
public static String sign(String userName, String userId) {
Date date = new Date(System.currentTimeMillis() + expire * 1000);
// 附带username信息
return JWT.create()
.withClaim("userId", userId)
.withExpiresAt(date)
.sign(algorithm);
} catch (Exception e) {
public static Long getExpire() {
return expire;
public static void setExpire(Long expire) {
JWTUtil.expire = expire;
public static String getSecret() {
return secret;
public static void setSecret(String secret) {
JWTUtil.secret = secret;
}
application.properties中增加：
#jwt token # token有效时长，7天，单位秒 jwt.expire=604800 jwt.secret=JWT_TOKEN_SHIRO
注意：jwt加解密的私钥使用配置的字符串而不使用用户登录密码的好处是防止用户密码被其他人修改后，用户操作系统此时再去校验token会发生token解析对不上的情况。
4.JWTFilter请求拦截
import org.apache.shiro.authz.UnauthorizedException;
import org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.net.URLEncoder;
/**
* jwt过滤器
*
* @Author yangfeng
* @Description preHandle->isAccessAllowed->isLoginAttempt->executeLogin
* @Date 2019-09-18
* @Time 12:36
*/
public class JWTFilter extends BasicHttpAuthenticationFilter {
private Logger logger = LoggerFactory.getLogger(this.getClass());
/**
* 如果带有 token，则对 token 进行检查，否则直接通过
*/
@Override
protected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) throws UnauthorizedException {
//判断请求的请求头是否带上 "Token"
if (isLoginAttempt(request, response)) {
//如果存在，则进入 executeLogin 方法执行登入，检查 token 是否正确
try {
executeLogin(request, response);
return true;
} catch (Exception e) {
//token 错误
responseError(response, e.getMessage());
return false; //产生异常则阻止请求的继续执行
}
}
//如果请求头不存在 Token，则可能是执行登陆操作或者是游客状态访问，无需检查 token，直接返回 true
return true;
}
/**
* 判断用户是否想要登入。
* 检测 header 里面是否包含 Token
*/
@Override
protected boolean isLoginAttempt(ServletRequest request, ServletResponse response) {
HttpServletRequest req = (HttpServletRequest) request;
String token = req.getHeader("Authorization");
return token != null;
}
/**
* 执行登陆操作
*/
@Override
protected boolean executeLogin(ServletRequest request, ServletResponse response) throws Exception {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
String token = httpServletRequest.getHeader("Authorization");
JWTToken jwtToken = new JWTToken(token);
// 提交给realm进行登入，如果错误他会抛出异常并被捕获
getSubject(request, response).login(jwtToken);
// 如果没有抛出异常则代表登入成功，返回true
return true;
}
/**
* 对跨域提供支持
*/
@Override
protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
httpServletResponse.setHeader("Access-control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "*");
httpServletResponse.setHeader("Access-Control-Allow-Headers", "*");
// 跨域时会首先发送一个option请求，这里我们给option请求直接返回正常状态
if (httpServletRequest.getMethod().equals(RequestMethod.OPTIONS.name())) {
httpServletResponse.setStatus(HttpStatus.OK.value());
return false;
}
return super.preHandle(request, response);
}
/**
* 请求异常跳转
*/
private void responseError(ServletResponse response, String message) {
try {
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
//设置编码，否则中文字符在重定向时会变为空字符串
message = URLEncoder.encode(message, "UTF-8");
httpServletResponse.sendRedirect("/pc/login/noLogin?message=" + message);
} catch (IOException e) {
logger.error(e.getMessage());
}
}
}
executeLogin()方法中的getSubject(request, response).login(jwtToken)就是触发Shiro 登录操作。

}
处理未登录、未授权等异常，返回相应的代码，方便前端捕获跳转登录页面，或者作出提示，而不会直接抛出服务器异常导致提示不够明确。
到此后端已经全部写完。接下来是vue部分。
9.缓存调用登录接口传过来的token
localStorage.setItem('token', token);
10.请求头设置，带上token
//封装请求
function xAxios(options) {
let opts = {...options};
let token = localStorage.getItem('token')
if (token) {
opts.headers['Authorization'] = token
}
11.生产环境nginx配置
因为后端jetFilter登录异常会进行重定向，所以nginx需要加上前端的代理配置。
