這篇文章主要介紹了基于springboot實現整合shiro實現登錄認證以及授權過程解析,文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值,需要的朋友可以參考下

1.添加shiro的依賴

<dependency>  <groupId>org.apache.shiro</groupId>      <artifactId>shiro-spring-boot-web-         starter</artifactId>  <version>1.4.0</version></dependency>

2.先創建一個Realm

public class MyShiroRealm extends AuthorizingRealm {  @Autowired  private RoleService roleService;//角色模模塊  @Autowired  private UserService userService;//用戶模塊  @Autowired  private PermissionService permissionService;//權限模塊  /**   * 用戶身份識別(登錄")   * @param authenticationToken   * @return   * @throws AuthenticationException   */  @Override  protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {    UsernamePasswordToken authToken = (UsernamePasswordToken) authenticationToken;    // 獲取用戶輸入的賬號    String userName = authToken.getUsername();　　　　　//通過賬號查找用戶信息    User user= userService.selectUserOne(userName);// 將賬戶名,密碼,鹽值,getName()實例化到SimpleAuthenticationInfo中交給Shiro來管理    SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(                              user,                              user.getPassWord(),　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　//這里是設置的密碼鹽                              ByteSource.Util.bytes(user.getSalt()),                              getName());    return authenticationInfo;  }  /**   * 訪問控制。比如某個用戶是否具有某個操作的使用權限   * @param principalCollection   * @return   */  @Override  protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {    SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();    String userName = (String) principalCollection.getPrimaryPrincipal();    if (userName == null) {      log.error("授權失敗，用戶信息為空?。?！");      return null;    }    try {      //獲取用戶角色集      Set<String> listRole= roleService.findRoleByUsername(userName);      simpleAuthorizationInfo.addRoles(listRole);      //通過角色獲取權限集      for (String role : listRole) {        Set<String> permission= permissionService.findPermissionByRole(role);        simpleAuthorizationInfo.addStringPermissions(permission);      }      return simpleAuthorizationInfo;    } catch (Exception e) {      log.error("授權失敗，請檢查系統內部錯誤!!!", e);    }    return simpleAuthorizationInfo;  }}

3.創建shiro的配置類

@Configurationpublic class ShiroConfiguration {　　 //配置自定義的Realm  @Bean  public MyShiroRealm myShiroRealm(HashedCredentialsMatcher matcher){    MyShiroRealm myShiroRealm= new MyShiroRealm();　　　　　//在這里配置密碼加密    myShiroRealm.setCredentialsMatcher(matcher);    return myShiroRealm;  }　　 //將Realm注冊到securityManager中  @Bean  public DefaultWebSecurityManager securityManager(HashedCredentialsMatcher matcher){    DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();    securityManager.setRealm(myShiroRealm(matcher));    return securityManager;  }  //如果沒有此name,將會找不到shiroFilter的Bean  @Bean(name = "shiroFilter")  public ShiroFilterFactoryBean shiroFilter(org.apache.shiro.mgt.SecurityManager securityManager){    ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();    shiroFilterFactoryBean.setSecurityManager(securityManager);    shiroFilterFactoryBean.setLoginUrl("/login");     //表示指定登錄頁面    shiroFilterFactoryBean.setSuccessUrl("/user/list");  // 登錄成功后要跳轉的鏈接    shiroFilterFactoryBean.setUnauthorizedUrl("/403");  //未授權頁面    Map<String,String> filterChainDefinitionMap = new LinkedHashMap<>();//攔截器, 配置不會被攔截的鏈接 順序判斷    filterChainDefinitionMap.put("/login","anon");           //所有匿名用戶均可訪問到Controller層的該方法下    filterChainDefinitionMap.put("/userLogin","anon");    filterChainDefinitionMap.put("/image/**","anon");    filterChainDefinitionMap.put("/css/**", "anon");    filterChainDefinitionMap.put("/fonts/**","anon");    filterChainDefinitionMap.put("/js/**","anon");    filterChainDefinitionMap.put("/logout","logout");    filterChainDefinitionMap.put("/**", "authc"); //authc:所有url都必須認證通過才可以訪問; anon:所有url都都可以匿名訪問    //filterChainDefinitionMap.put("/**", "user");    //user表示配置記住我或認證通過可以訪問的地址    shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);    return shiroFilterFactoryBean;  }  /**   * SpringShiroFilter首先注冊到spring容器   * 然后被包裝成FilterRegistrationBean   * 最后通過FilterRegistrationBean注冊到servlet容器   * @return   */  @Bean  public FilterRegistrationBean delegatingFilterProxy(){    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();    DelegatingFilterProxy proxy = new DelegatingFilterProxy();    proxy.setTargetFilterLifecycle(true);    proxy.setTargetBeanName("shiroFilter");    filterRegistrationBean.setFilter(proxy);    return filterRegistrationBean;  }  //設置cookie  @Bean  public SimpleCookie rememberMeCookie(){    //這個參數是cookie的名稱,對應前端的checkbox的name=rememberMe    SimpleCookie simpleCookie = new SimpleCookie("rememberMe");    //記住我cookie生效時間3個小時(單位秒)    simpleCookie.setMaxAge(10800);    return simpleCookie;  }  //cookie管理對象,記住我功能  @Bean  public CookieRememberMeManager rememberMeManager(){    CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager();    cookieRememberMeManager.setCookie(rememberMeCookie());    return cookieRememberMeManager;  }  /**   * 密碼匹配憑證管理器（密碼加密需要此配置）   * @return   */  @Bean(name = "hashedCredentialsMatcher")  public HashedCredentialsMatcher hashedCredentialsMatcher() {    HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();    hashedCredentialsMatcher.setHashAlgorithmName("MD5");    hashedCredentialsMatcher.setHashIterations(1024);// 設置加密次數    return hashedCredentialsMatcher;  }  //如果沒有這兩個配置，可能會授權失敗，所以依賴中還需要配置aop的依賴  @Bean  public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(HashedCredentialsMatcher matcher) {    AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();    authorizationAttributeSourceAdvisor.setSecurityManager(securityManager(matcher));    return authorizationAttributeSourceAdvisor;  }  @Bean  @ConditionalOnMissingBean  public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator(){    DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator=new DefaultAdvisorAutoProxyCreator();    defaultAdvisorAutoProxyCreator.setProxyTargetClass(true);    return defaultAdvisorAutoProxyCreator;  }}
