demo源码

此demo用SpringBoot+Shiro简单实现了登陆、注册、认证、授权的功能，并用redis做分布式缓存提高性能。

1.准备工作

导入pom.xml

</html>

3.实现User、Role、Permission三个POJO

package com.ego.pojo;
import com.baomidou.mybatisplus.annotation.*;
import io.swagger.annotations.apiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("t_user")
@ApiModel("用户实体类")
public class User implements Serializable {
    
    @TableId(type = IdType.AUTO)
    @ApiModelProperty(name = "id", value = "ID 主键")
    private Integer id;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "username", value = "用户名")
    private String username;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "password", value = "密码")
    private String password;
    @TableField(fill = FieldFill.INSERT)
    @ApiModelProperty(name = "salt", value = "盐")
    private String salt;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "age", value = "年龄")
    private Integer age;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "email", value = "邮箱")
    private String email;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "address", value = "地址")
    private String address;
    @TableField(exist = false)
    private List<Role> roles = new ArrayList<>();
}
package com.ego.pojo;
import com.baomidou.mybatisplus.annotation.*;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("t_role")
@ApiModel("角色实体类")
public class Role implements Serializable {
    
    @TableId(type = IdType.AUTO)
    @ApiModelProperty(name = "id", value = "ID 主键")
    private Integer id;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "name", value = "角色名称")
    private String name;
    @TableField(exist = false)
    private List<Permission> permissions = new ArrayList<>();
}
package com.ego.pojo;
import com.baomidou.mybatisplus.annotation.*;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;

@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("t_permission")
@ApiModel("权限实体类")
public class Permission implements Serializable {
    
    @TableId(type = IdType.AUTO)
    @ApiModelProperty(name = "id", value = "ID主键")
    private Integer id;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "name", value = "权限名称")
    private String name;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(name = "url", value = "权限菜单URL")
    private String url;
}

4.实现Controller、Service、Dao

这里dao采用了mybatis-plus

package com.ego.controller;
import com.ego.pojo.User;
import com.ego.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/user")
public class UserController {
    @Autowired
    private UserService userService;
    
    @RequestMapping("/login")
    public String login(String username,String password){
        // 获取当前登录用户
        Subject subject = SecurityUtils.getSubject();
        try {
            // 执行登录操作
            subject.login(new UsernamePasswordToken(username,password));
            // 认证通过后直接跳转到index.jsp
            return "redirect:/index.jsp";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            System.out.println("用户名错误！");
        } catch (IncorrectCredentialsException e) {
            System.out.println("密码错误！");
        } catch (Exception e) {
        }
        // 如果认证失败仍然回到登录页面
        return "redirect:/login.jsp";
    }
    @RequestMapping("/logout")
    public String logout(){
        subject.logout();
        // 退出后仍然会到登录页面
     * 用户注册
     * @param user
    @RequestMapping("/register")
    public String register(User user){
            userService.register(user);
            return "redirect:/login.jsp";
        return "redirect:/register.jsp";
}
package com.ego.service.impl;
import com.ego.dao.mapper.UserMapper;
import com.ego.shiro.ShiroConstant;
import com.ego.utils.SaltUtil;
import org.apache.shiro.crypto.hash.Md5Hash;
import org.springframework.stereotype.Service;
@Service("userService")
public class UserServiceImpl implements UserService {
    private UserMapper userMapper;
    @Override
    public void register(User user) {
        //生成随机盐
        String salt = SaltUtil.getSalt(ShiroConstant.SALT_LENGTH);
        //保存随机盐
        user.setSalt(salt);
        //生成密码
        Md5Hash password = new Md5Hash(user.getPassword(), salt, ShiroConstant.HASH_ITERATORS);
        //保存密码
        user.setPassword(password.toHex());
        userMapper.insert(user);
    public User findUserByUserName(String userName) {
        return userMapper.findUserByUserName(userName);
import com.ego.dao.mapper.RoleMapper;
import com.ego.pojo.Role;
import com.ego.service.RoleService;
import java.util.List;
@Service("roleService")
public class RoleServiceImpl implements RoleService {
    private RoleMapper roleMapper;
    public List<Role> getRolesByUserId(Integer userId) {
        return roleMapper.getRolesByUserId(userId);
import com.ego.dao.mapper.PermissionMapper;
import com.ego.pojo.Permission;
import com.ego.service.PermissionService;
@Service("permissionService")
public class PermissionServiceImpl implements PermissionService {
    private PermissionMapper permissionMapper;
    public List<Permission> getPermissionsByRoleId(Integer roleId) {
        return permissionMapper.getPermissionsByRoleId(roleId);
package com.ego.dao.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
@Mapper
public interface UserMapper extends BaseMapper<User> {
    @Select("SELECT u.id,u.username,u.password,u.salt,u.age,u.email,u.address FROM t_user u WHERE u.username = #{username}")
    User findUserByUserName(String username);
public interface RoleMapper extends BaseMapper<Role> {
    @Select("select r.id,r.name from t_role r left join t_user_role ur on ur.role_id = r.id where ur.user_id = #{userId}")
    List<Role> getRolesByUserId(Integer userId);
public interface PermissionMapper extends BaseMapper<Permission> {
    @Select("select p.id,p.name,p.url from t_permission p left join t_role_permission rp on rp.permission_id = p.id where rp.role_id = #{roleId}")
    List<Permission> getPermissionsByRoleId(Integer roleId);

5.实现SaltUtil和ApplicationContextUtil两个工具类

package com.ego.utils;
import java.util.Random;

public class SaltUtil {
    public static String getSalt(int n){
        char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < n; i++) {
            char aChar = chars[new Random().nextInt(chars.length)];
            sb.append(aChar);
        }
        return sb.toString();
    }
}
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;
@Component
public class ApplicationContextUtil implements ApplicationContextAware {
    public static ApplicationContext context;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.context = applicationContext;
    
    public static Object getBean(String beanName){
        return context.getBean(beanName);

6.实现核心Shiro

package com.ego.utils;
import java.util.Random;

public class SaltUtil {
    public static String getSalt(int n){
        char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < n; i++) {
            char aChar = chars[new Random().nextInt(chars.length)];
            sb.append(aChar);
        }
        return sb.toString();
    }
}
package com.ego.utils;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextUtil implements ApplicationContextAware {
    public static ApplicationContext context;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.context = applicationContext;
    }
    
    public static Object getBean(String beanName){
        return context.getBean(beanName);
    }
}

7.实现Redis分布式缓存

package com.ego.shiro;
import com.ego.shiro.cache.RedisCacheManager;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.realm.Realm;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.HashMap;
import java.util.Map;

@Configuration
public class ShiroConfiguration {
    //1.创建shiroFilter  //负责拦截所有请求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //给filter设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        //配置系统受限资源
        //配置系统公共资源
        Map<String,String> map = new HashMap<String,String>();
        map.put("/user/login", "anon");
        map.put("/user/register","anon");
        map.put("/register.jsp","anon");
        map.put("/index.jsp","authc");//authc 请求这个资源需要认证和授权
        //默认认证界面路径
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
        return shiroFilterFactoryBean;
    }
    //2.创建安全管理器
    public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm){
        DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
        //给安全管理器设置
        defaultWebSecurityManager.setRealm(realm);
        return defaultWebSecurityManager;
    //3.创建自定义realm
    public Realm getRealm(){
        CustomerRealm customerRealm = new CustomerRealm();
        // 设置密码匹配器
        HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
        // 设置加密方式
        credentialsMatcher.setHashAlgorithmName(ShiroConstant.HASH_ALGORITHM_NAME.MD5);
        // 设置散列次数
        credentialsMatcher.setHashIterations(ShiroConstant.HASH_ITERATORS);
        customerRealm.setCredentialsMatcher(credentialsMatcher);
        // 设置缓存管理器
        customerRealm.setCacheManager(new RedisCacheManager());
        // 开启全局缓存
        customerRealm.setCachingEnabled(true);
        // 开启认证缓存并指定缓存名称
        customerRealm.setAuthenticationCachingEnabled(true);
        customerRealm.setAuthenticationCacheName("authenticationCache");
        // 开启授权缓存并指定缓存名称
        customerRealm.setAuthorizationCachingEnabled(true);
        customerRealm.setAuthorizationCacheName("authorizationCache");
        return customerRealm;
}
public class ShiroConstant {
    
    public static final int SALT_LENGTH = 8;
    
    public static final int HASH_ITERATORS = 1024;
    public interface HASH_ALGORITHM_NAME {
        String MD5 = "MD5";
import com.ego.pojo.Permission;
import com.ego.pojo.Role;
import com.ego.pojo.User;
import com.ego.service.PermissionService;
import com.ego.service.RoleService;
