Spring Security基于数据库的认证
创建数据库

让bean实现UserDetails接口
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;
}
public void setUsername(String username) {
this.username = username;
}
public void setPassword(String password) { this.password = password; }
public void setEnabled(Boolean enabled) {
this.enabled = enabled;
}
public void setLocked(Boolean locked) {
this.locked = locked;
}
@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 String getUsername() {
return username;
}
//账户是否未过期
@Override
public boolean isAccountNonExpired() {
return true;
}
//账户是否未锁定
@Override
public boolean isAccountNonLocked() {
return !locked;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return enabled;
}
}
public class Role {
private Integer id;
private String name;
private String nameZh;
...
}
userMapper
在类上直接加@Mapper或者在SpringBoot启动类上配置全局的扫描@MapperScan(basePackages="")
@Mapper
public interface UserMapper {
User loadUserByUsername(String username);
List<Role> getUserRolesById(Integer id);
}
<?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="com.qwl.mysecuritydb.mapper.UserMapper">
<select id="loadUserByUsername" resultType="com.qwl.mysecuritydb.bean.User">
select * from user where username = #{username}
</select>
<select id="getUserRolesById" resultType="com.qwl.mysecuritydb.bean.Role">
select * from role where id in(select rid from user_role where uid=#{id})
</select>
</mapper>
userService 同样也要继承UserServiceDetails接口
@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;
}
}
HelloController
@RestController
public class HelloController {
@GetMapping("/hello")
public String hello(){
return "hello security";
}
@GetMapping("/dba/hello")
public String dba(){
return "hello dba";
}
@GetMapping("/admin/hello")
public String admin(){
return "hello admin";
}
@GetMapping("/user/hello")
public String user(){
return "hello user";
}
}
SecurityConfig
- SercurityConfig需要继承WebSecurityConfigurerAdapter类，并在类上加@Configuration
- SpringSecurity5.0之后密码必须加密
- 把数据库查出的用户信息交给SpringSecurity处理
- 配置httpSercurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
UserService userService;
//把数据库查出的用户信息交给SpringSecurity处理
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userService);
}
@Bean
PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
@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();
}
}
