Spring boot 加入shiro支持

在项目添加依赖

       <!-- shiro spring. -->
	<dependency>
		<groupId>org.apache.shiro</groupId>
		<artifactId>shiro-spring</artifactId>
		<version>1.4.0</version>
	</dependency>
	<!-- shiro core -->
	<dependency>
		<groupId>org.apache.shiro</groupId>
		<artifactId>shiro-core</artifactId>
		<version>1.4.0</version>
	</dependency>

配置文件目录下新建spring文件夹，在文件夹内新建spring-shiro.xml文件

在主入口加载spring-shiro.xml

@ImportResource({ "classpath:spring/spring-shiro.xml" })

在登录Controller内更改成

		//构造登录参数
		UsernamePasswordToken token = new UsernamePasswordToken(name, pwd);
		try {
			//交给Realm类处理
			SecurityUtils.getSubject().login(token);
		} catch (UnknownAccountException uae) {
			map.put("msg", "未知用户");
			return "login";
		} catch (IncorrectCredentialsException ice) {
			map.put("msg", "密码错误");
			return "login";
		} catch (AuthenticationException ae) {
			// unexpected condition? error?
			map.put("msg", "服务器繁忙");
			return "login";
		}
	 
		return "redirect:/toIndex";

看5行就知道登录交给了Realm类处理了，所以我们要有Realm类

在可以被主入口扫描到的地方新建AuthRealm类并且继承AuthorizingRealm，重写doGetAuthenticationInfo（登录逻辑），重写doGetAuthorizationInfo（授权逻辑）

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

public class AuthRealm extends AuthorizingRealm {

	@Override
	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
		// TODO Auto-generated method stub
		return null;
	}

}

登录验证在doGetAuthenticationInfo方法写入

		// 获取Token
		UsernamePasswordToken token2 = (UsernamePasswordToken) token;
		//获取用户名
		String userName = token2.getUsername();
		//获取密码
		String pwd = new String(token2.getPassword());
		//下面我使用的是MyBatis-puls3.0
		//查询条件对象
		QueryWrapper<User> queryWrapper = new QueryWrapper();
		//查询该用户
		queryWrapper.eq("name", userName).or().eq("phone", userName);
		//查询
		User user = iUserService.getOne(queryWrapper);
		//查回的对象为空
		if (CommonUtil.isBlank(user)) {
			//抛出未知的账户异常
			throw new UnknownAccountException();
		}
		//查回的对象密码和输入密码不相等
		if (!CommonUtil.isEquals(user.getPwd(), pwd)) {
			//抛出凭证不正确异常
			throw new IncorrectCredentialsException();
		}
		//上面都通过了就说明该用户存在并且密码相等
		// 验证成功了
		SecurityUtils.getSubject().getSession().setAttribute(Constant.SESSION_USER_KEY, user);
		// 返回shiro用户信息
		// token传过来的密码，一定要跟验证信息传进去的密码一致，加密的密码一定要加密后传过来

		return new SimpleAuthenticationInfo(user, user.getPwd(), getName());

如果要设置权限，就在对应的Controllerf方法加上

@RequiresPermissions("/system/user/list")

再doGetAuthorizationInfo方法内写

//创建简单的授权信息对象
SimpleAuthorizationInfo simpleAuthorizationInfo=new SimpleAuthorizationInfo();
//授予权限
simpleAuthorizationInfo.addStringPermission("/system/user/list");

return simpleAuthorizationInfo;

　　

当所有Controller都加了@RequiresPermissions注解后，如果访问到没有授权的Controller会报错。
