shiro密码加密

话不多说，先上思路
重写SimpleCredentialsMatcher类的method
doCredentialsMatch

散列加密  盐值自己加

public class CustomCredentialsMatcher extends SimpleCredentialsMatcher{
	@Override  
    public boolean doCredentialsMatch(AuthenticationToken authcToken, AuthenticationInfo info) {  
        UsernamePasswordToken token = (UsernamePasswordToken) authcToken;  

        Object tokenCredentials = encrypt(String.valueOf(token.getPassword()));  
        Object accountCredentials = getCredentials(info);  
        //将密码加密与系统加密后的密码校验，内容一致就返回true,不一致就返回false  
        return equals(tokenCredentials, accountCredentials);  
    }  

    //将传进来密码加密方法  
    public String encrypt(String data) {  
        String sha384Hex = new Sha384Hash(data).toHex();//这里可以选择自己的密码验证方式 比如 md5或者sha256等  
        return sha384Hex;  
    } 

在AuthorizingRealm重写initCredentialsMatcher    shiro验证

	@PostConstruct
	public void initCredentialsMatcher() {
		// 该句作用是重写shiro的密码验证，让shiro用我自己的验证
		setCredentialsMatcher(new CustomCredentialsMatcher());

	}
