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;
/**
* @author 袁梦达 2019012364
*/
@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("t_user")
@ApiModel("用户实体类")
public class User implements Serializable {
/** 数据库中设置该字段自增时该注解不能少 **/
@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;
/**
* @author 袁梦达 2019012364
*/
@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("t_role")
@ApiModel("角色实体类")
public class Role implements Serializable {
/** 数据库中设置该字段自增时该注解不能少 **/
@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;
/**
* @author 袁梦达 2019012364
*/
@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("t_permission")
@ApiModel("权限实体类")
public class Permission implements Serializable {
/** 数据库中设置该字段自增时该注解不能少 **/
@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;
/**
* @author 袁梦达 2019012364
*/
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
/**
* 用户登录
* @param username
* @param password
* @return
*/
@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;
/**
* @author 袁梦达 2019012364
*/
public class SaltUtil {
public static String getSalt(int n){
char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < n; i++) {
char aChar = chars[new Random().nextInt(chars.length)];
sb.append(aChar);
}
return sb.toString();
}
}
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;
@Component
public class ApplicationContextUtil implements ApplicationContextAware {
public static ApplicationContext context;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.context = applicationContext;
/**
* 根据工厂中的类名获取类实例
*/
public static Object getBean(String beanName){
return context.getBean(beanName);
6.实现核心Shiro
package com.ego.utils;
import java.util.Random;
/**
* @author 袁梦达 2019012364
*/
public class SaltUtil {
public static String getSalt(int n){
char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".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;
/**
* @author 袁梦达 2019012364
*/
@Component
public class ApplicationContextUtil implements ApplicationContextAware {
public static ApplicationContext context;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.context = applicationContext;
}
/**
* 根据工厂中的类名获取类实例
*/
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;
/**
* @author 袁梦达 2019012364
*/
@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 {
/** 随机盐的位数 **/
public static final int SALT_LENGTH = 8;
