从外部来看Shiro,即从应用程序角度的来观察如何使用Shiro完成工作
查看官方文档:http://shiro.apache.org/tutorial.html
官方的quickstart : https://github.com/apache/shiro/tree/master/samples/quickstart/
创建一个maven父工程,用来学习Shiro,删掉不必要的部分
创建一个普通的Maven子工程:hell-shiro
根据官方文档,我们导入Shiro的依赖

// The easiest way to create a Shiro SecurityManager with configured

// We'll do that by using a factory that can ingest a .ini file and
// return a SecurityManager instance:
// Use the shiro.ini file at the root of the classpath
// (file: and url: prefixes load from files and urls respectively):
// 读取配置文件:
Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
SecurityManager securityManager = factory.getInstance();
// for this simple example quickstart, make the SecurityManager
// accessible as a JVM singleton. Most applications wouldn't do this
// and instead rely on their container configuration or web.xml for
// webapps. That is outside the scope of this simple quickstart, so
// we'll just do the bare minimum so you can continue to get a feel

编写导入配置类
编写一个自定义类UserRealm
//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了=>授权doGetAuthorizationInfo");
return null;
}
//认证
@Override

编写配置ShiroConfig
@Configuration
public class ShiroConfig {
//3. shiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager) {
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();

return securityManager;
}
//1. 创建realm对象,需要自定义类
@Bean
public UserRealm userRealm() {
return new UserRealm();
}
}
在ShiroConfig
中的getShiroFilterFactoryBean

Map<String, String> filterMap = new LinkedHashMap<>();
filterMap.put("/user/add","authc");
filterMap.put("/user/update","authc");
//filterMap.put("/user/*","authc"); 通配符
bean.setFilterChainDefinitionMap(filterMap);
点击首页的add或者update之后
添加拦截成功页面

在MyConfig中添加
@RequestMapping("/toLogin")
public String toLogin() {
return "login";
}
在ShiroConfig

方法中添加如下配置
//设置登录的请求
bean.setLoginUrl("/toLogin");
拦截成功页面
在MyController

@RequestMapping("/login")
public String login(String username, String password, Model model) {
//获取一个用户
Subject subject = SecurityUtils.getSubject();
// 封装用户的登录数据
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
try {

return "index";
} catch (UnknownAccountException e) {//用户名不存在
model.addAttribute("msg","用户名错误");
return "login";
} catch (IncorrectCredentialsException e) {//密码不存在
model.addAttribute("msg","密码错误");

//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了=>认证doGetAuthorizationInfo");
// 用户名、密码, 数据中取
String name = "root";
String password = "123";

UserService接口实现
public interface UserService {

UserServiceImpl业务逻辑

public User queryUserByName(String name) {
return userMapper.queryUserByName(name);
}
}

测试环境
@SpringBootTest

@Autowired
UserService userService;
@Test
void contextLoads() {
System.out.println(userService.queryUserByName("狂神"));
}
}
1234567891011
UserRealm
连接真实数据库
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了=>认证doGetAuthorizationInfo");
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
// 真实数据库 用户名、密码, 数据中取
User user = userService.queryUserByName(userToken.getUsername());
if (user == null) {//没有这个人
return null;
}
// 密码认证,shiro做
return new SimpleAuthenticationInfo("",user.getPwd(),"");
}
1234567891011121314151617
断点测试密码加密类型
ShiroConfig
中的getShiroFilterFactoryBean
方法添加认证代码
//授权,正常情况下,没有授权会跳转到为授权页面
filterMap.put("/user/add","perms[user:add]");
filterMap.put("/user/update","perms[user:update]");
登录之后点击add按钮会弹出如下页面
添加为授权页面
MyController
@RequestMapping("/noauto")
@ResponseBody
public String unauthorized() {
return "未经授权,无法访问此页面";
}
ShiroConfig
中的getShiroFilterFactoryBean
方法中添加
//为授权页面
bean.setUnauthorizedUrl("/noauto");
再次测试
所以需要在UserRealm中为用户进行真正授权
在数据库中添加一个perms字段
pojo修改:
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String name;
private String pwd;
private String perms;
}
UserRealm类的修改
//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {
@Autowired
UserService userService;
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了=>授权doGetAuthorizationInfo");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//拿到当前登录的这个对象
Subject subject = SecurityUtils.getSubject();
User currentUser = (User)subject.getPrincipal();//拿到user对象
//设置当前用户的权限
info.addStringPermission(currentUser.getPerms());
return info;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
......
// 密码认证,shiro做
return new SimpleAuthenticationInfo(user,user.getPwd(),"");
}
}
