通过逆向工程将五张表生成对应的model、mapper

<table schema="" tableName="t_shiro_user" domainObjectName="ShiroUser"
       enableCountByExample="false" enableDeleteByExample="false"
       enableSelectByExample="false" enableUpdateByExample="false">
</table>
<table schema="" tableName="t_shiro_role" domainObjectName="ShiroRole"
       enableCountByExample="false" enableDeleteByExample="false"
       enableSelectByExample="false" enableUpdateByExample="false">
</table>
<table schema="" tableName="t_shiro_permission" domainObjectName="ShiroPermission"
       enableCountByExample="false" enableDeleteByExample="false"
       enableSelectByExample="false" enableUpdateByExample="false">

Mapper(ShiroUserMapper)中新增

<select id="queryByName" resultType="com.javaxl.ssm.model.ShiroUser" parameterType="java.lang.String">
  select
  <include refid="Base_Column_List" />
  from t_shiro_user
  where userName = #{userName}

md5加盐加密

加密目的：为了数据的安全性
加密现象：将明文密码转换成密文
加密——》加盐
但是由于加密是一个明文对应一个密文，解密轻而易举于是有了加盐（一个明文生成多个密文）这个概念。

盐加密工具类
在做新增用户的时候使用，将加密后的密码、及加密时候的盐放入数据库；本篇博客中的表数据是现成的，暂时用不上这个工具类去生成数据

package com.zxp.ssm.utli;

import org.apache.shiro.crypto.RandomNumberGenerator;
import org.apache.shiro.crypto.SecureRandomNumberGenerator;
import org.apache.shiro.crypto.hash.SimpleHash;

public class PasswordHelper {

    /**
     * 随机数生成器
     */
    private static RandomNumberGenerator randomNumberGenerator = new SecureRandomNumberGenerator();

    /**
     * 指定hash算法为MD5
     */
    private static final String hashAlgorithmName = "md5";

    /**
     * 指定散列次数为1024次，即加密1024次
     */
    private static final int hashIterations = 1024;

    /**
     * true指定Hash散列值使用Hex加密存. false表明hash散列值用用Base64-encoded存储
     */
    private static final boolean storedCredentialsHexEncoded = true;

    /**
     * 获得加密用的盐
     *
     * @return
     */
    public static String createSalt() {
        return randomNumberGenerator.nextBytes().toHex();
    }

    /**
     * 获得加密后的凭证
     *
     * @param credentials 凭证(即密码)
     * @param salt        盐
     * @return
     */
    public static String createCredentials(String credentials, String salt) {
        SimpleHash simpleHash = new SimpleHash(hashAlgorithmName, credentials,
                salt, hashIterations);
        return storedCredentialsHexEncoded ? simpleHash.toHex() : simpleHash.toBase64();
    }


    /**
     * 进行密码验证
     *
     * @param credentials        未加密的密码
     * @param salt               盐
     * @param encryptCredentials 加密后的密码
     * @return
     */
    public static boolean checkCredentials(String credentials, String salt, String encryptCredentials) {
        return encryptCredentials.equals(createCredentials(credentials, salt));
    }

    
}

测试

public static void main(String[] args) {
        //盐
        String salt = createSalt();
        System.out.println(salt);
        System.out.println(salt.length());
        //凭证+盐加密后得到的密码
        String credentials = createCredentials("123", salt);
        System.out.println(credentials);
        System.out.println(credentials.length());
        boolean b = checkCredentials("123", salt, credentials);
        System.out.println(b);
    }
