前言
一、sso结构实现
二、使用步骤
2.1 建一个spring cloud 项目
2.2 common下的core的配置
2.3 实现系统的业务微服务
2.4 sso模块的编写
总结
单点登录(SingleSignOn，SSO)，就是通过用户的一次性鉴别登录。当用户在身份认证服务器上登录一次以后，即可获得访问单点登录系统中其他关联系统和应用软件的权限，同时这种实现是不需要管理员对用户的登录状态或其他信息进行修改的，这意味着在多个应用系统中，用户只需一次登录就可以访问所有相互信任的应用系统。这种方式减少了由登录产生的时间消耗，辅助了用户管理，是比较流行的
在总的父工程下添加 父工程使用
2.3.12.RELEASE 的springboot项目创建 然后添加以下 <packaging>pom</packaging>
<!--定义版本号-->
<properties>
<java.version>1.8</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF- 8</project.reporting.outputEncoding>
<spring-cloud.version>Hoxton.SR8</spring-cloud.version>
<spring-cloud-alibaba.version>2.2.3.RELEASE</spring-cloud-alibaba.version>
</properties>
<!--jar得管理 它只负责jar得管理不负责下载-->

}jwt工具类和前端数据处理vo
public class JwtUtil {

//1.生成jwt的token方法
public static String createJWT(Map<String,Object> map){
//定义头信息
Map<String,Object> head= new HashMap<>();
head.put("alg","HS256");
head.put("typ","JWT");
//定义颁发时间
Date iat=new Date();
//过期时间
Calendar expire = Calendar.getInstance();
expire.set(Calendar.SECOND,24*3600);//24*3600
Date expireTime = expire.getTime();
String token = JWT.create()
//头信息
.withHeader(head)
//设置颁发时间
.withIssuedAt(iat)
//设置过期时间
.withExpiresAt(expireTime)
//自定义的内容
.withClaim("userinfo",map)
//签名
.sign(Algorithm.HMAC256(sign));
return token;
}
//2.校验token是否有效
public static boolean verifyToken(String token){
//获取一个JWT校验对象
JWTVerifier build = JWT.require(Algorithm.HMAC256(sign)).build();
try {
//调用校验功能
DecodedJWT verify = build.verify(token);
return true;
}catch (Exception e){
System.out.println("token无效");
return false;
}
}
//3.从token中获取相关的载荷内容
public static Map<String,Object> getTokenChaim(String token){
//获取一个JWT校验对象
JWTVerifier build = JWT.require(Algorithm.HMAC256(sign)).build();
//调用校验功能
DecodedJWT verify = build.verify(token);
Claim loginInfo = verify.getClaim("userinfo");
return loginInfo.asMap();
}
}
