com.auth0.jwt.JWT;在pom.xml中如何导入

您可以在pom.xml文件中添加以下依赖关系来导入com.auth0.jwt.JWT：

<dependency>
    <groupId>com.auth0</groupId>
    <artifactId>java-jwt</artifactId>
    <version>3.18.1</version>
</dependency>

请注意，您需要确保已在您的项目中包含Maven依赖项。

springboot+shiro的框架怎么写呢，我的maven是：<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring-boot-web-starter</artifactId> <version>1.8.0</version> </dependency> <dependency> <groupId>com.auth0</groupId> <artifactId>java-jwt</artifactId> <version>3.18.2</version> </dependency>

好的，对于使用 Spring Boot 和 Shiro 框架的项目，可以参照以下步骤进行搭建：

1. 在 pom.xml 文件中添加依赖：

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring-boot-web-starter</artifactId>
    <version>1.8.0</version>
</dependency>
<dependency>
    <groupId>com.auth0</groupId>
    <artifactId>java-jwt</artifactId>
    <version>3.18.2</version>
</dependency>

其中，shiro-spring-boot-web-starter 是 Shiro 在 Spring Boot 中的集成包，java-jwt 是用于生成和解析 JWT 的库。

2. 在 application.properties 或 application.yml 文件中配置 Shiro：

# 配置 Shiro 的加密方式
shiro.hashAlgorithmName=md5
shiro.hashIterations=2

# 配置 JWT 的过期时间
jwt.expireTime=1800

# 配置 Shiro 的登录路径和首页路径
shiro.loginUrl=/login
shiro.successUrl=/index

# 配置 Shiro 的过滤器链
shiro.filterChainDefinitionMap= \
    /static/** = anon \
    /login = anon \
    /logout = logout \
    /** = authc

其中，shiro.hashAlgorithmName 和 shiro.hashIterations 是 Shiro 的加密方式，jwt.expireTime 是 JWT 的过期时间，shiro.loginUrl 和 shiro.successUrl 是 Shiro 的登录路径和首页路径，shiro.filterChainDefinitionMap 是 Shiro 的过滤器链。

3. 创建 Shiro 配置类，用于配置 Shiro 的各种组件：

@Configuration
public class ShiroConfig {

    // 配置 SecurityManager
    @Bean
    public SecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(myRealm()); // 配置自定义 Realm
        securityManager.setRememberMeManager(cookieRememberMeManager()); // 配置 RememberMeManager
        securityManager.setSessionManager(sessionManager()); // 配置 SessionManager
        return securityManager;
    }

    // 配置自定义 Realm
    @Bean
    public MyRealm myRealm() {
        return new MyRealm();
    }

    // 配置 RememberMeManager
    @Bean
    public RememberMeManager cookieRememberMeManager() {
        CookieRememberMeManager rememberMeManager = new CookieRememberMeManager();
        rememberMeManager.setCookie(rememberMeCookie());
        return rememberMeManager;
    }

    // 配置 RememberMeCookie
    @Bean
    public SimpleCookie rememberMeCookie() {
        SimpleCookie cookie = new SimpleCookie("rememberMe");
        cookie.setMaxAge(86400); // 设置 Cookie 的过期时间为一天
        return cookie;
    }

    // 配置 SessionManager
    @Bean
    public DefaultWebSessionManager sessionManager() {
        DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();
        sessionManager.setSessionIdCookieEnabled(true);
        sessionManager.setSessionIdUrlRewritingEnabled(false);
        sessionManager.setSessionDAO(redisSessionDAO()); // 配置 RedisSessionDAO
        sessionManager.setGlobalSessionTimeout(1800000); // 设置 Session 的过期时间为半小时
        sessionManager.setDeleteInvalidSessions(true);
        sessionManager.setSessionValidationSchedulerEnabled(true);
        return sessionManager;
    }

    // 配置 RedisSessionDAO
    @Bean
    public RedisSessionDAO redisSessionDAO() {
        RedisSessionDAO redisSessionDAO = new RedisSessionDAO();
        redisSessionDAO.setRedisManager(redisManager()); // 配置 RedisManager
        redisSessionDAO.setKeyPrefix("shiro:session:");
        redisSessionDAO.setExpire(1800); // 设置 Session 的过期时间为半小时
        return redisSessionDAO;
    }

    // 配置 RedisManager
    @Bean
    public RedisManager redisManager() {
        RedisManager redisManager = new RedisManager();
        redisManager.setHost("localhost");
        redisManager.setPort(6379);
        redisManager.setTimeout(0);
        return redisManager;
    }

    // 配置 ShiroFilterFactoryBean
    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean() {
        ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
        factoryBean.setSecurityManager(securityManager());
        factoryBean.setLoginUrl("/login");
        factoryBean.setSuccessUrl("/index");
        factoryBean.setUnauthorizedUrl("/unauthorized");
        factoryBean.setFilterChainDefinitionMap(shiroFilterChainDefinition().getFilterChainMap());
        return factoryBean;
    }

    // 配置 ShiroFilterChainDefinition
    @Bean
    public ShiroFilterChainDefinition shiroFilterChainDefinition() {
        DefaultShiroFilterChainDefinition chainDefinition = new DefaultShiroFilterChainDefinition();
        chainDefinition.addPathDefinition("/static/**", "anon");
        chainDefinition.addPathDefinition("/login", "anon");
        chainDefinition.addPathDefinition("/logout", "logout");
        chainDefinition.addPathDefinition("/**", "authc");
        return chainDefinition;
    }
}

其中，myRealm() 方法用于配置自定义 Realm，cookieRememberMeManager() 方法用于配置 RememberMeManager 和 RememberMeCookie，sessionManager() 方法用于配置 SessionManager 和 RedisSessionDAO，redisManager() 方法用于配置 RedisManager，shiroFilterFactoryBean() 方法用于配置 ShiroFilterFactoryBean，shiroFilterChainDefinition() 方法用于配置 ShiroFilterChainDefinition。

4. 创建自定义 Realm 类，用于实现用户的认证和授权逻辑：

public class MyRealm extends AuthorizingRealm {

    // 配置加密方式
    @Override
    public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {
        HashedCredentialsMatcher matcher = new HashedCredentialsMatcher();
        matcher.setHashAlgorithmName("md5");
        matcher.setHashIterations(2);
        super.setCredentialsMatcher(matcher);
    }

    // 用户认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        UsernamePasswordToken upToken = (UsernamePasswordToken) token;
        String username = upToken.getUsername();
        String password = new String(upToken.getPassword());
        // 根据用户名和密码查询用户信息
        User user = userService.findByUsernameAndPassword(username, password);
        if (user == null) {
            throw new UnknownAccountException("用户名或密码错误");
        }
        SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getPassword(), getName());
        return info;
    }

    // 用户授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        User user = (User) principals.getPrimaryPrincipal();
        // 根据用户角色查询权限信息
        List<Role> roles = userService.findRolesByUsername(user.getUsername());
        for (Role role : roles) {
            info.addRole(role.getName());
            List<Permission> permissions = role.getPermissions();
            for (Permission permission : permissions) {
                info.addStringPermission(permission.getName());
            }
        }
        return info;
    }
}

在自定义 Realm 类中，通过 setCredentialsMatcher() 方法配置加密方式，通过 doGetAuthenticationInfo() 方法实现用户的认证逻辑，通过 doGetAuthorizationInfo() 方法实现用户的授权逻辑。

5. 创建登录控制器，用于处理用户的登录和注销：

@Controller
public class LoginController {

    @GetMapping("/login")
    public String login() {
        return "login";
    }

    @PostMapping("/login")
    public String login(String username, String password, boolean rememberMe, HttpServletRequest request) {
        try {
            // 将用户名和密码封装成 UsernamePasswordToken 对象
            UsernamePasswordToken token = new UsernamePasswordToken(username, password);
            // 设置 RememberMe
            token.setRememberMe(rememberMe);
            // 执行登录操作
            SecurityUtils.getSubject().login(token);
            return "redirect:/index";
        } catch (UnknownAccountException e) {
            request.setAttribute("error", "用户名不存在");
        } catch (IncorrectCredentialsException e) {
            request.setAttribute("error", "密码错误");
        } catch (LockedAccountException e) {
            request.setAttribute("error", "账号已被锁定");
        } catch (AuthenticationException e) {
            request.setAttribute("error", "登录失败：" + e.getMessage());
        }
        return "login";
    }

    @GetMapping("/logout")
    public String logout() {
        SecurityUtils.getSubject().logout();
        return "redirect:/login";
    }
}

在登录控制器中，通过 login() 方法实现用户的登录操作，通过 logout() 方法实现用户的注销操作。

6. 在页面中添加登录界面和首页，例如：

<!-- 登录界面 -->
<form method="post" action="/login">
    <div class="form-group">
        <label for="username">用户名：</label>
        <input type="text" id="username" name="username" class="form-control" required>
    </div>
    <div class="form-group">
        <label for="password">密码：</label>
        <input type="password" id="password" name="password" class="form-control" required>
    </div>
    <div class="form-check">
        <input type="checkbox" id="rememberMe" name="rememberMe" class="form-check-input">
        <label for="rememberMe" class="form-check-label">记住我</label>
    </div>
    <button type="submit" class="btn btn-primary">登录</button>
</form>

<!-- 首页 -->
<h1>欢迎登录</h1>
<p><a href="/logout">退出登录</a></p>

通过以上步骤，就可以使用 Spring Boot 和 Shiro 框架来实现用户的认证和授权了，当然，在具体实现时，还需要针对自己的业务需求进行一些调整和优化。

SpringBoot整合JWT 用java-jwt依赖包实现

可以通过以下步骤在Spring Boot中集成JWT：

1. 添加java-jwt依赖包到pom.xml文件中：

<dependency>
    <groupId>com.auth0</groupId>
    <artifactId>java-jwt</artifactId>
    <version>3.18.1</version>
</dependency>

2. 创建一个JWT工具类来生成和验证JWT令牌：

import com.auth0.jwt.JWT;
import com.auth0.jwt.algorithms.Algorithm;
import com.auth0.jwt.exceptions.JWTVerificationException;
import com.auth0.jwt.interfaces.DecodedJWT;

import java.util.Date;

public class JwtUtils {

    private static final long EXPIRATION_TIME = 86400000; // 24 hours
    private static final String SECRET = "mySecret";
    private static final String ISSUER = "myIssuer";

    public static String generateToken(String username) {
        Date now = new Date();
        Date expiryDate = new Date(now.getTime() + EXPIRATION_TIME);

        return JWT.create()
                .withSubject(username)
                .withIssuer(ISSUER)
                .withIssuedAt(now)
                .withExpiresAt(expiryDate)
                .sign(Algorithm.HMAC512(SECRET));
    }

    public static String getUsernameFromToken(String token) throws JWTVerificationException {
        DecodedJWT jwt = JWT.require(Algorithm.HMAC512(SECRET))
                .withIssuer(ISSUER)
                .build()
                .verify(token);

        return jwt.getSubject();
    }
}

3. 在Spring Security配置中添加JWT过滤器，以验证JWT令牌：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.http.HttpStatus;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.config.annotation.SecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.HttpStatusEntryPoint;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Configuration
@Order(1)
public class JwtConfig extends SecurityConfigurerAdapter<javax.servlet.Filter, HttpSecurity> {

    @Autowired
    private JwtAuthenticationProvider jwtAuthenticationProvider;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        JwtAuthenticationFilter jwtAuthenticationFilter = new JwtAuthenticationFilter();
        jwtAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
        jwtAuthenticationFilter.setAuthenticationFailureHandler(new JwtAuthenticationFailureHandler());
        http.addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
    }

    private class JwtAuthenticationFilter extends UsernamePasswordAuthenticationFilter {

        @Override
        public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
            String token = request.getHeader("Authorization");

            if (token == null || !token.startsWith("Bearer ")) {
                throw new JwtAuthenticationException("Invalid JWT token");
            }

            String username = JwtUtils.getUsernameFromToken(token.substring(7));

            if (username == null) {
                throw new JwtAuthenticationException("Invalid JWT token");
            }

            return jwtAuthenticationProvider.authenticate(new UsernamePasswordAuthenticationToken(username, ""));
        }

        @Override
        protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException {
            super.successfulAuthentication(request, response, chain, authResult);
            chain.doFilter(request, response);
        }
    }

    private class JwtAuthenticationFailureHandler extends HttpStatusEntryPoint {

        @Override
        public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException {
            response.setStatus(HttpStatus.UNAUTHORIZED.value());
        }
    }
}

4. 创建一个JwtAuthenticationProvider来验证用户名和密码：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;

@Component
public class JwtAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        String username = authentication.getName();
        String password = (String) authentication.getCredentials();

        UserDetails userDetails = userDetailsService.loadUserByUsername(username);

        if (!passwordEncoder.matches(password, userDetails.getPassword())) {
            throw new JwtAuthenticationException("Invalid username or password");
        }

        return new UsernamePasswordAuthenticationToken(username, password, userDetails.getAuthorities());
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }
}

5. 在Spring Security配置中添加JwtConfig：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private JwtAuthenticationProvider jwtAuthenticationProvider;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(jwtAuthenticationProvider);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .antMatcher("/**")
                .authorizeRequests()
                .antMatchers("/login").permitAll()
                .anyRequest().authenticated()
                .and()
                .apply(new JwtConfig());
    }
}

现在你就可以在Spring Boot应用程序中使用JWT进行身份验证了。
