添加依赖
shiro依赖、数据库驱动依赖、mybatis-plus依赖、生成器依赖（注意：模板依赖）
<dependencies> <!--shiro-spring 依赖 --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.7.1</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!--mysql 依赖 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.26</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.20</version> </dependency> <!--mybatis-plus 依赖 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.2.0</version> </dependency> <!--mybatis-plus的生成器 依赖 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.4.1</version> </dependency> <!--mybatis-plus的生成器中模板 依赖 --> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies>
编写UserServiceImpl
@Service public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService { @Override public User findByName(String username) { return baseMapper.selectOne(new LambdaQueryWrapper<User>().eq(User::getUsername, username)); } }
Realm
public class ShiroRealm extends AuthorizingRealm { @Autowired private IUserService userServiceImpl; /** * 认证 * @param authenticationToken * @return * @throws AuthenticationException */ @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { String principal = (String) authenticationToken.getPrincipal(); User user = userServiceImpl.findByName(principal); if(user!=null){ return new SimpleAuthenticationInfo(user.getUsername(),user.getPassword(),this.getName()); } return null; } /** * 授权 * @param principalCollection * @return */ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { return null; } }
ShiroRealm没有被标记为spring容器管理的bean，为什么可以@AutoWired属性注入呢？
原因是在ShiroConfig中，shiroRealm被Spring容器管理
@Configuration public class ShiroConfig { //ShiroFilterFactoryBean（过滤器工厂对象：初始化SecurityManager、请求处理） @Bean public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) { ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean(); // 设置 securityManager shiroFilterFactoryBean.setSecurityManager(securityManager); LinkedHashMap<String, String> filterChainDefinitionMap = new LinkedHashMap<>(); filterChainDefinitionMap.put("/login", "anon"); // 所有请求都要认证 filterChainDefinitionMap.put("/**", "authc"); shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap); //指定登录页面 shiroFilterFactoryBean.setLoginUrl("/tologin"); return shiroFilterFactoryBean; } //DefaultWebSecurityManager（对应SecurityManager对象） @Bean public SecurityManager securityManager() { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); // 配置 SecurityManager，并注入 shiroRealm securityManager.setRealm(shiroRealm()); return securityManager; } //Realm 需要自定义 @Bean public ShiroRealm shiroRealm() { // 配置 Realm return new ShiroRealm(); } }
加密
在数据准备时密码是经过加密处理的，但是登录请求的密码是明文，密码通过equals方法继续比较的，所以比较之前需要把明文密码进行加密处理
shiro中密码比较默认匹配器是equals
在AuthenticatingRealm中的assertCredentialsMatch
可以看到getCredentialsMatcher方法获取匹配器，那么就可以设置匹配器不使用其默认匹配器。
在shiro的配置类中的Realm对象设置匹配器
//Realm 需要自定义 @Bean public ShiroRealm shiroRealm() { // 配置 Realm ShiroRealm shiroRealm = new ShiroRealm(); //修改密码匹配器 HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher(); hashedCredentialsMatcher.setHashAlgorithmName("MD5"); shiroRealm.setCredentialsMatcher(hashedCredentialsMatcher); return shiroRealm; }
