2、創建實體類

PermissionEntity.java

 1 package com.xiaostudy.shiro_test1.entity;
 2 
 3 import java.io.Serializable;
 4 
 5 /**
 6  * 權限實體類

10  * Time: 14:21
11  * Description: No Description
12  */
13 public class PermissionEntity implements Serializable {
14     private String id;
15     private String name;
16     private String url;
17 
18     public String getId() {
19         return id;
20     }
21 
22     public void setId(String id) {
23         this.id = id;
24     }
25 
26     public String getName() {
27         return name;
28     }
29 
30     public void setName(String name) {
31         this.name = name;
32     }
33 
34     public String getUrl() {
35         return url;
36     }
37 
38     public void setUrl(String url) {
39         this.url = url;
40     }
41 }

 1 package com.xiaostudy.shiro_test1.entity;
 2 
 3 import java.io.Serializable;
 4 import java.util.HashSet;
 5 import java.util.Set;
 6 
 7 /**
 8  * 角色實體類

12  * Time: 14:24
13  * Description: No Description
14  */
15 public class RoleEntity implements Serializable {
16     private String id;
17     private String name;
18     private Set<PermissionEntity> permissions = new HashSet<>();
19 
20     public String getId() {
21         return id;
22     }
23 
24     public void setId(String id) {
25         this.id = id;
26     }
27 
28     public String getName() {
29         return name;
30     }
31 
32     public void setName(String name) {
33         this.name = name;
34     }
35 
36     public Set<PermissionEntity> getPermissions() {
37         return permissions;
38     }
39 
40     public void setPermissions(Set<PermissionEntity> permissions) {
41         this.permissions = permissions;
42     }
43 }

 1 package com.xiaostudy.shiro_test1.entity;
 2 
 3 import java.io.Serializable;
 4 import java.util.HashSet;
 5 import java.util.Set;

14  */
15 public class UserEntity implements Serializable {
16     private String id;
17     private String name;
18     private String password;
19     private Set<RoleEntity> roles = new HashSet<>();
20 
21     public String getId() {
22         return id;
23     }
24 
25     public void setId(String id) {
26         this.id = id;
27     }
28 
29     public String getName() {
30         return name;
31     }
32 
33     public void setName(String name) {
34         this.name = name;
35     }
36 
37     public String getPassword() {
38         return password;
39     }
40 
41     public void setPassword(String password) {
42         this.password = password;
43     }
44 
45     public Set<RoleEntity> getRoles() {
46         return roles;
47     }
48 
49     public void setRoles(Set<RoleEntity> roles) {
50         this.roles = roles;
51     }
52 }

實體類entity，也可以叫bean、domain，具體叫什可以根據自己的喜歡選取

3、數據庫創建表和添加數據

 1  DROP TABLE IF EXISTS `role_permission`;
 2  DROP TABLE IF EXISTS `permission`;
 3  DROP TABLE IF EXISTS `user_role`;
 4  DROP TABLE IF EXISTS `role`;
 5  DROP TABLE IF EXISTS `user`;
 6 
 7  CREATE TABLE `user` (
 8  `id` VARCHAR(255) PRIMARY KEY,
 9  `name` VARCHAR(255),
10  `password` VARCHAR(255)
11  ) engine = InnoDB default charset = utf8 comment = '用戶表';
12 
13  CREATE TABLE `role` (
14  `id` VARCHAR(255) PRIMARY KEY,
15  `name` VARCHAR(255)
16  ) engine = InnoDB default charset = utf8 comment = '角色表';
17 
18  CREATE TABLE `user_role` (
19  `id` VARCHAR(255) PRIMARY KEY,
20  `user_id` VARCHAR(255),
21  `role_id` VARCHAR(255),
22  FOREIGN KEY (`user_id`) REFERENCES `user`(id),
23  FOREIGN KEY (`role_id`) REFERENCES `role`(id)
24  ) engine = InnoDB default charset = utf8 comment = '用戶與角色多對多表';
25 
26  CREATE TABLE `permission` (
27  `id` VARCHAR(255) PRIMARY KEY,
28  `name` VARCHAR(255),
29  `url` VARCHAR(255)
30  ) engine = InnoDB default charset = utf8 comment = '權限表';
31 
32  CREATE TABLE `role_permission` (
33  `id` VARCHAR(255) PRIMARY KEY,
34  `role_id` VARCHAR(255),
35  `permission_id` VARCHAR(255),
36  FOREIGN KEY (`role_id`) REFERENCES `role`(id),
37  FOREIGN KEY (`permission_id`) REFERENCES `permission`(id)
38  ) engine = InnoDB default charset = utf8 comment = '角色與權限多對多表';
39 
40 insert into `user` (`id`, `name`, `password`) values('1','admin','123456');
41 insert into `user` (`id`, `name`, `password`) values('2','vip','123456');
42 insert into `user` (`id`, `name`, `password`) values('3','svip','1234');
43 
44 insert into `role` (`id`, `name`) values('1','user');
45 insert into `role` (`id`, `name`) values('2','vip');
46 insert into `role` (`id`, `name`) values('3','svip');
47 
48 insert into `permission` (`id`, `name`, `url`) values('1','user','user');
49 insert into `permission` (`id`, `name`, `url`) values('2','vip','vip');
50 insert into `permission` (`id`, `name`, `url`) values('3','svip','svip');
51 
52 insert into `user_role` (`id`, `user_id`, `role_id`) values('1','1','1');
53 insert into `user_role` (`id`, `user_id`, `role_id`) values('2','2','1');
54 insert into `user_role` (`id`, `user_id`, `role_id`) values('3','2','2');
55 insert into `user_role` (`id`, `user_id`, `role_id`) values('4','3','1');
56 insert into `user_role` (`id`, `user_id`, `role_id`) values('5','3','2');
57 insert into `user_role` (`id`, `user_id`, `role_id`) values('6','3','3');
58 
59 insert into `role_permission` (`id`, `role_id`, `permission_id`) values('1','1','1');
60 insert into `role_permission` (`id`, `role_id`, `permission_id`) values('2','2','1');
61 insert into `role_permission` (`id`, `role_id`, `permission_id`) values('3','2','2');
62 insert into `role_permission` (`id`, `role_id`, `permission_id`) values('4','3','1');
63 insert into `role_permission` (`id`, `role_id`, `permission_id`) values('5','3','2');
64 insert into `role_permission` (`id`, `role_id`, `permission_id`) values('6','3','3');

4、接下來寫mapper，也叫dao

 1 package com.xiaostudy.shiro_test1.mapper;
 2 
 3 import com.xiaostudy.shiro_test1.entity.UserEntity;
 4 import org.apache.ibatis.annotations.Mapper;
 5 
 6 /**
 7  * Created with IntelliJ IDEA.
 8  * User: Administrator
 9  * Date: 2019/6/8
10  * Time: 14:45
11  * Description: No Description
12  */
13 @Mapper
14 public interface UserMapper {
15 
16     // 根據用戶名稱，查詢用戶信息
17     public UserEntity findByName(String name);
18 
19     // 根據用戶id，查詢用戶信息、角色、權限
20     public UserEntity findById(String id);
21 }

@Mapper后面再講，這里也可以不用@Mapper

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
 3 <mapper namespace="com.xiaostudy.shiro_test1.mapper.UserMapper">

19 
20     <select id="findByName" parameterType="java.lang.String" resultType="com.xiaostudy.shiro_test1.entity.UserEntity">
21       SELECT id, name, password
22         FROM user
23           WHERE name = #{name}
24     </select>
25 
26     <select id="findById" parameterType="java.lang.String" resultMap="userMap">
27       SELECT user.id, user.name, user.password,
28             role.id as roleId, role.name as roleName,
29             permission.id as permissionId,
30             permission.name as permissionName,
31             permission.url as permissionUrl
32         FROM user, user_role, role, role_permission, permission
33           WHERE user.id = #{id}
34             AND user.id = user_role.user_id
35             AND user_role.role_id = role.id
36             AND role.id = role_permission.role_id
37             AND role_permission.permission_id = permission.id
38     </select>
39 
40 </mapper>

5、下面寫service

 1 package com.xiaostudy.shiro_test1.service;
 2 
 3 import com.xiaostudy.shiro_test1.entity.UserEntity;
 4 
 5 /**
 6  * Created with IntelliJ IDEA.
 7  * User: Administrator
 8  * Date: 2019/6/8
 9  * Time: 14:55
10  * Description: No Description
11  */
12 public interface UserService {
13 
14     UserEntity findByName(String name);
15 
16     UserEntity findById(String id);
17 }

 1 package com.xiaostudy.shiro_test1.service.impl;
 2 
 3 import com.xiaostudy.shiro_test1.entity.UserEntity;
 4 import com.xiaostudy.shiro_test1.mapper.UserMapper;
 5 import com.xiaostudy.shiro_test1.service.UserService;
 6 import org.springframework.beans.factory.annotation.Autowired;
 7 import org.springframework.stereotype.Service;
 8 
 9 /**
10  * Created with IntelliJ IDEA.
11  * User: Administrator
12  * Date: 2019/6/8
13  * Time: 14:56
14  * Description: No Description
15  */
16 @Service
17 public class UserServiceImpl implements UserService {
18 
19     @Autowired
20     private UserMapper userMapper;
21 
22     @Override
23     public UserEntity findByName(String name) {
24         return userMapper.findByName(name);
25     }
26 
27     @Override
28     public UserEntity findById(String id) {
29         return userMapper.findById(id);
30     }
31 }

6、下面寫自定義Realm的UserRealm.java

 1 package com.xiaostudy.shiro_test1.realm;
 2 
 3 import com.xiaostudy.shiro_test1.entity.PermissionEntity;
 4 import com.xiaostudy.shiro_test1.entity.RoleEntity;
 5 import com.xiaostudy.shiro_test1.entity.UserEntity;
 6 import com.xiaostudy.shiro_test1.service.UserService;
 7 import org.apache.shiro.SecurityUtils;
 8 import org.apache.shiro.authc.*;
 9 import org.apache.shiro.authz.AuthorizationInfo;
10 import org.apache.shiro.authz.SimpleAuthorizationInfo;
11 import org.apache.shiro.realm.AuthorizingRealm;
12 import org.apache.shiro.subject.PrincipalCollection;
13 import org.apache.shiro.subject.Subject;
14 import org.apache.shiro.util.ByteSource;
15 import org.springframework.beans.factory.annotation.Autowired;
16 
17 import java.util.Collection;
18 import java.util.HashSet;
19 import java.util.Set;
20 
21 /**

27  * Description: No Description
28  */
29 public class UserRealm extends AuthorizingRealm {
30 
31     @Autowired
32     private UserService userService;
33 
34     /**
35      * 用戶授權
36      **/
37     @Override
38     protected AuthorizationInfo doGetAuthorizationInfo(
39             PrincipalCollection principalCollection) {
40 
41         System.out.println("===執行授權===");
42 
43         Subject subject = SecurityUtils.getSubject();
44         UserEntity user = (UserEntity)subject.getPrincipal();
45         if(user != null){
46             SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
47             // 角色字符串集合
48             Collection<String> rolesCollection = new HashSet<>();
49             // 權限字符串集合
50             Collection<String> premissionCollection = new HashSet<>();
51             // 讀取並賦值用戶角色與權限
52             Set<RoleEntity> roles = user.getRoles();
53             for(RoleEntity role : roles){
54                 rolesCollection.add(role.getName());
55                 Set<PermissionEntity> permissions = role.getPermissions();
56                 for (PermissionEntity permission : permissions){
57                     // 權限名稱為PermissionEntity為字段url
58                     premissionCollection.add(permission.getUrl());
59                 }
60                 info.addStringPermissions(premissionCollection);

63             return info;
64         }
65         return null;
66     }
67 
68     /**
69      * 用戶認證
70      **/
71     @Override
72     protected AuthenticationInfo doGetAuthenticationInfo(
73             AuthenticationToken authenticationToken) throws AuthenticationException {
74 
75         System.out.println("===執行認證===");
76 
77         UsernamePasswordToken token = (UsernamePasswordToken)authenticationToken;
78         UserEntity bean = userService.findByName(token.getUsername());
79 
80         if(bean == null){
81             // 用戶不存在
82             throw new UnknownAccountException();
83         } else {
84             bean = userService.findById(bean.getId());
85             if(null == bean) {
86                 // 認證失敗

94                 credentialsSalt, getName());
95     }
96 }

7、下面寫shiro配置類

 1 package com.xiaostudy.shiro_test1.config;
 2 
 3 import com.xiaostudy.shiro_test1.realm.UserRealm;
 4 import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
