Shiro整合Spring

1. Shiro加密

文档：http://shiro.apache.org/cryptography.html

1) shiro加密解密

2) shiro加密应用

CryptographyUtil.java

package com.andrew.util;
import org.apache.shiro.codec.Base64;
import org.apache.shiro.crypto.hash.Md5Hash;
public class CryptographyUtil {
    /**
     * base64加密
     * 
     * @param str
     * @return
     */
    public static String encBase64(String str) {
        return Base64.encodeToString(str.getBytes());
    }
    /**
     * base64解密
     * 
     * @param str
     * @return
     */
    public static String decBase64(String str) {
        return Base64.decodeToString(str);
    }
    /**
     * Md5加密
     * 
     * @param str
     * @param salt
     * @return
     */
    public static String md5(String str, String salt) {
        return new Md5Hash(str, salt).toString();
    }
    public static void main(String[] args) {
        String password = "123456";
        System.out.println("Base64加密：" + CryptographyUtil.encBase64(password));
        System.out.println("Base64解密：" + CryptographyUtil.decBase64(CryptographyUtil.encBase64(password)));
        System.out.println("Md5加密：" + CryptographyUtil.md5(password, "andrew"));
    }
}

运行结果:
Base64加密：MTIzNDU2
Base64解密：123456
Md5加密：fe6bcd14f8e15e83a6b9593c2e8eba60

2. Shiro支持特性

1) Web支持
2) 缓存支持
3) 并发支持
4) 测试支持
5) "RunAs"支持
6) "RememberMe"支持
if (subject.isRemembered()) {
    System.out.println("---isRememberMe---");
} else {
    token.setRememberMe(true);                
}
