CAS5.3自定义加密方法获取用户名

CAS5自定义加密方法获取用户名

项目用到CAS单点登录，根据用户名自定义加密方式

1. 添加pom.xml依赖

          <dependency>
                    <groupId>javax.servlet</groupId>
                    <artifactId>javax.servlet-api</artifactId>
                    <version>3.1.0</version>
          </dependency>

2.修改application.properties文件

cas.authn.jdbc.query[0].passwordEncoder.type=org.apereo.cas.MyPasswordEncode
#cas.authn.jdbc.query[0].passwordEncoder.encodingAlgorithm=MD5

3. 实现PasswordEncoder接口，根据上下文获取用户名

@Component
public class MyPasswordEncode implements PasswordEncoder {


    @Override
    public String encode(CharSequence rawPassword) {
        String password = String.valueOf(rawPassword);
        //通过上下文获取用户输入用户名
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();
        String username = String.valueOf(request.getParameter("username"));
        String passwordEncode = PasswordUtil.encrypt(username, password);
        return passwordEncode;
    }

    @Override
    public boolean matches(CharSequence rawPassword, String encodedPassword) {
        // 判断密码为空,直接返回false
        if (StringUtils.isBlank(rawPassword)) {
            return false;
        }
        //调用上面的encode 对请求密码进行自定义加密处理
        String pass = this.encode(rawPassword.toString());
        //比较密码是否相等
        return pass.equals(encodedPassword);

    }
