CAS 单点登录4.24版本 登录调用其它系统并且返回客户端用其它的用户信息改造

1.登录调用其它系统。修改deployerConfigContext.xml

　　3.UsernamePasswordStrongCredential的改造，用于存入调用登录接口返回的用户信息存入map中

package com.hivecas.model;

        return new HashCodeBuilder().append(getUsername())  
                .append(getPassword()).append(authcode).toHashCode();  
    }  
}

　　4.UserInfoPrincipalResolver.java

package org.jasig.cas.authentication.principal;


import javax.validation.constraints.NotNull;

import org.jasig.cas.authentication.Credential;

     */

        return credential.getId();
    }
