一篇文章带你搞定 springsecurity基于数据库的认证(springsecurity整合mybatis)
一、前期配置
1. 加入依赖
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> <version>5.1.27</version> </dependency>
这里选定的 mysql-connector-java
连接版本是 5.1.27,对应的 application.properties
为:
spring.datasource.url=jdbc:mysql://localhost:3306/yolo spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.username=root spring.datasource.password=root
如果是 8.0以上版本则 application.properties
需要对于 spring.datasource.url
需要加入 serverTimezone
spring.datasource.username=root spring.datasource.password=root spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.url=jdbc:mysql://localhost:3306/security?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
2. 数据库脚本
SET FOREIGN_KEY_CHECKS=0; -- ---------------------------- -- Table structure for role -- ---------------------------- DROP TABLE IF EXISTS `role`; CREATE TABLE `role` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(32) DEFAULT NULL, `nameZh` varchar(32) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of role -- ---------------------------- INSERT INTO `role` VALUES ('1', 'dba', '数据库管理员'); INSERT INTO `role` VALUES ('2', 'admin', '系统管理员'); INSERT INTO `role` VALUES ('3', 'user', '用户'); -- ---------------------------- -- Table structure for user -- ---------------------------- DROP TABLE IF EXISTS `user`; CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(32) DEFAULT NULL, `password` varchar(255) DEFAULT NULL, `enabled` tinyint(1) DEFAULT NULL, `locked` tinyint(1) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of user -- ---------------------------- INSERT INTO `user` VALUES ('1', 'root', '$2a$10$RMuFXGQ5AtH4wOvkUqyvuecpqUSeoxZYqilXzbz50dceRsga.WYiq', '1', '0'); INSERT INTO `user` VALUES ('2', 'admin', '$2a$10$RMuFXGQ5AtH4wOvkUqyvuecpqUSeoxZYqilXzbz50dceRsga.WYiq', '1', '0'); INSERT INTO `user` VALUES ('3', 'sang', '$2a$10$RMuFXGQ5AtH4wOvkUqyvuecpqUSeoxZYqilXzbz50dceRsga.WYiq', '1', '0'); -- ---------------------------- -- Table structure for user_role -- ---------------------------- DROP TABLE IF EXISTS `user_role`; CREATE TABLE `user_role` ( `id` int(11) NOT NULL AUTO_INCREMENT, `uid` int(11) DEFAULT NULL, `rid` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of user_role -- ---------------------------- INSERT INTO `user_role` VALUES ('1', '1', '1'); INSERT INTO `user_role` VALUES ('2', '1', '2'); INSERT INTO `user_role` VALUES ('3', '2', '2'); INSERT INTO `user_role` VALUES ('4', '3', '3'); SET FOREIGN_KEY_CHECKS=1;
二、定义实体类
1. 定义 User
实体类 User 需要实现 UserDetails 接口,因为每个人都可以定义 User 对象,但是每个人定义的 User对象不一样,这就造成每个人设置的属性不一样,当系统需要判定用户的登录状态时,因为用户名和密码的名称设置的五花八门,造成无法确定调用哪个
所以这里要求所有的实体类实现 UserDetails 接口,它就相当于一个规范定义了登录验证时需要的属性名称,所以的实体类都要符合这个规范。
public class User implements UserDetails { private Integer id; private String username; private String password; private Boolean enabled; private Boolean locked; private List<Role> roles; public List<Role> getRoles() { return roles; } public void setRoles(List<Role> roles) { this.roles = roles; } public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } @Override public String getUsername() { return username; } @Override public boolean isAccountNonExpired() { return true; } @Override public boolean isAccountNonLocked() { return !locked; } @Override public boolean isCredentialsNonExpired() { return true; } @Override public boolean isEnabled() { return enabled; } public void setUsername(String username) { this.username = username; } @Override public Collection<? extends GrantedAuthority> getAuthorities() { List<SimpleGrantedAuthority> authorities = new ArrayList<>(); for (Role role : roles) { authorities.add(new SimpleGrantedAuthority("ROLE_"+role.getName())); } return authorities; } @Override public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public void setEnabled(Boolean enabled) { this.enabled = enabled; } public void setLocked(Boolean locked) { this.locked = locked; } }
(1) accountNonExpired、accountNonLocked、credentialsNonExpired、enabled 这四个属性分别用来描述用户的状态,表示账户是否没有过期、账户是否没有被锁定、密码是否没有过期、以及账户是否可用。
(2)roles 属性表示用户的角色,User 和 Role 是多对多关系,用一个 @ManyToMany 注解来描述。
(3)getAuthorities 方法返回用户的角色信息,我们在这个方法中把自己的 Role 稍微转化一下即可。
(1)这个集合是返回用户的所有角色,因为从数据库得到是 roles,但是需要的是一个集合形式的 getAuthorities
,所以需要对其进行处理。
@Override public Collection<? extends GrantedAuthority> getAuthorities() { List<SimpleGrantedAuthority> authorities = new ArrayList<>(); for (Role role : roles) { authorities.add(new SimpleGrantedAuthority("ROLE_"+role.getName())); } return authorities; }
这里注意springsecurity 角色的认证有一个要求,必须是以 ROLE_
开始的,否则会出现问题:
authorities.add(new SimpleGrantedAuthority("ROLE_"+role.getName()));
当然也可以在数据中添加用户时,就让用户以 ROLE_
开始,这样就不用二次添加了
(2)另外需要注意这里的 isAccountNonLocked()
,账户是否没有被锁定,数据库中存储的是:
所以这里是对 locked 取的反
@Override public boolean isAccountNonLocked() { return !locked; }
2. 定义 Role
public class Role { private Integer id; private String name; private String nameZh; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getNameZh() { return nameZh; } public void setNameZh(String nameZh) { this.nameZh = nameZh; } }
三、定义 Service
@Service public class UserService implements UserDetailsService { @Autowired UserMapper userMapper; @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { User user = userMapper.loadUserByUsername(username); if (user == null) { throw new UsernameNotFoundException("用户不存在!"); } user.setRoles(userMapper.getUserRolesById(user.getId())); return user; } }
我们自己定义的 UserService
需要实现 UserDetailsService
接口,实现该接口,就要实现接口中的方法,也就是 loadUserByUsername
,这个方法的参数就是用户在登录的时候传入的用户名,根据用户名去查询用户信息(查出来之后,系统会自动进行密码比对)。
四、定义 Mapper
1. UserMapper
@Mapper public interface UserMapper { User loadUserByUsername(String username); List<Role> getUserRolesById(Integer id); }
2. UserMapper.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="org.javaboy.securitydb.mapper.UserMapper"> <select id="loadUserByUsername" resultType="org.yolo.securitymybatis.bean.User"> select * from user where username=#{username} </select> <select id="getUserRolesById" resultType="org.yolo.securitymybatis.bean.Role"> select * from role where id in (select rid from user_role where uid=#{id}) </select> </mapper>
Mapper 的位置:
所以需要为其添加资源路径:资源配置路径添加到 pom 文件中
<resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> <resource> <directory>src/main/resources</directory> </resource> </resources>
五、定义 SecurityConfig
@Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired UserService userService; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userService); } @Bean PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } @Bean RoleHierarchy roleHierarchy() { RoleHierarchyImpl roleHierarchy = new RoleHierarchyImpl(); String hierarchy = "ROLE_dba > ROLE_admin \n ROLE_admin > ROLE_user"; roleHierarchy.setHierarchy(hierarchy); return roleHierarchy; } @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/dba/**").hasRole("dba") .antMatchers("/admin/**").hasRole("admin") .antMatchers("/user/**").hasRole("user") .anyRequest().authenticated() .and() .formLogin() .permitAll() .and() .csrf().disable(); } }
