Shiro加密

Shiro加密

1.1 在CustomRealmTest中设置Shiro加密名称和加密次数

//Shiro加密
HashedCredentialsMatcher matcher = new HashedCredentialsMatcher();
//加密名称
matcher.setHashAlgorithmName("md5");
//加密的次数
matcher.setHashIterations(1);
customRealm.setCredentialsMatcher(matcher);

CustomRealmTest类完整代码

package com.amoscxy.test;

import com.amoscxy.shiro.realm.CustomRealm;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.subject.Subject;
import org.junit.Test;

public class CustomRealmTest {

	@Test
	public void testAuthentication(){
		
		CustomRealm customRealm = new CustomRealm();
		
		//1.构建SecurityManager
		DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
		defaultSecurityManager.setRealm(customRealm);

		//Shiro加密
		HashedCredentialsMatcher matcher = new HashedCredentialsMatcher();
		//加密名称
		matcher.setHashAlgorithmName("md5");
		//加密的次数
		matcher.setHashIterations(1);
		customRealm.setCredentialsMatcher(matcher);
		
		//2.主体提交认证请求
		SecurityUtils.setSecurityManager(defaultSecurityManager);
		Subject subject = SecurityUtils.getSubject();
		
		UsernamePasswordToken token = new UsernamePasswordToken("Mark","1234567");
		subject.login(token);
		
		System.out.println("isAuthenticated:"+subject.isAuthenticated());
		
		subject.checkRole("admin");

		subject.checkPermissions("user:add","user:delete");
	
	}
}

1.2 计算CustomRealm中密码的加盐md5加密值，修改密码为加密值

Map<String,String> userMap = new HashMap<String, String>(16);

{
    userMap.put("Mark","d40fdd323f5322ff34a41f026f35cf20");
    super.setName("customRealm");
}

1.3 CustomRealm中的认证函数doGetAuthenticationInfo中设置盐值

/**
 * 做认证
 * @param authenticationToken
 * @return
 * @throws AuthenticationException:主体传过来的认证信息
 */
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    //1.从主体传过来的认证信息中，获得用户名
    String userName = (String)authenticationToken.getPrincipal();
    //2.通过用户名到数据库获取凭证
    String password = getPasswordByUserName(userName);
    if(password == null){
        return null;
    }
    SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(userName,password,"customRealm");
    //设置盐值
    authenticationInfo.setCredentialsSalt(ByteSource.Util.bytes("Mark"));
    return authenticationInfo;
}
