這篇文章主要介紹了Spring Security基于數(shù)據(jù)庫(kù)實(shí)現(xiàn)認(rèn)證過(guò)程解析,文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友可以參考下

創(chuàng)建數(shù)據(jù)庫(kù)

讓bean實(shí)現(xiàn)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;
  }

  //賬戶是否未過(guò)期
  @Override
  public boolean isAccountNonExpired() {
    return true;
  }

  //賬戶是否未鎖定
  @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

在類上直接加@Mapper或者在SpringBoot啟動(dòng)類上配置全局的掃描@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 同樣也要繼承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("用戶不存在");
    }
    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需要繼承WebSecurityConfigurerAdapter類，并在類上加@Configuration
SpringSecurity5.0之后密碼必須加密
把數(shù)據(jù)庫(kù)查出的用戶信息交給SpringSecurity處理
配置httpSercurity

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
  @Autowired
  UserService userService;

		//把數(shù)據(jù)庫(kù)查出的用戶信息交給SpringSecurity處理
  @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();

  }
}
