Shiro的认证过程

protected abstract AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken var1) throws AuthenticationException;

currentUser.login(token);login方法的实现void login(AuthenticationToken var1) throws AuthenticationException;

public void login(AuthenticationToken token) throws AuthenticationException {    this.clearRunAsIdentitiesInternal();    Subject subject = this.securityManager.login(this, token);    String host = null;    PrincipalCollection principals;    if (subject instanceof DelegatingSubject) {        DelegatingSubject delegating = (DelegatingSubject)subject;        principals = delegating.principals;        host = delegating.host;    } else {        principals = subject.getPrincipals();    }
    if (principals != null && !principals.isEmpty()) {        this.principals = principals;        this.authenticated = true;        if (token instanceof HostAuthenticationToken) {            host = ((HostAuthenticationToken)token).getHost();        }
        if (host != null) {            this.host = host;        }
        Session session = subject.getSession(false);        if (session != null) {            this.session = this.decorate(session);        } else {            this.session = null;        }
    } else {        String msg = "Principals returned from securityManager.login( token ) returned a null or empty value.  This value must be non null and populated with one or more elements.";        throw new IllegalStateException(msg);    }}

info = this.authenticate(token);
public AuthenticationInfo authenticate(AuthenticationToken token) throws AuthenticationException {    return this.authenticator.authenticate(token);}

==============public final AuthenticationInfo getAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {    AuthenticationInfo info = this.getCachedAuthenticationInfo(token);    if (info == null) {        info = this.doGetAuthenticationInfo(token);        log.debug("Looked up AuthenticationInfo [{}] from doGetAuthenticationInfo", info);        if (token != null && info != null) {            this.cacheAuthenticationInfoIfPossible(token, info);        }    } else {        log.debug("Using cached authentication info [{}] to perform credentials matching.", info);    }
    if (info != null) {        this.assertCredentialsMatch(token, info);    } else {        log.debug("No AuthenticationInfo found for submitted AuthenticationToken [{}].  Returning null.", token);    }
    return info;}

int i = token.hashCode();此时的hashcode与 info = this.doGetAuthenticationInfo(token);doGetAuthenticationInfo获取的token是一致的

public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {    Object tokenCredentials = getCredentials(token);    Object accountCredentials = getCredentials(info);    return equals(tokenCredentials, accountCredentials);}public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {    this.credentialsMatcher = credentialsMatcher;}
