Spring Security用户定义 

目录

• 一、基于内存
• 二、基于mybatis

基于内存的和基于数据库的，下面我给大家简单介绍一下这两种方式。

一、基于内存

Spring Security中的配置：

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
    manager.createUser(User.withUsername("admin").password("{noop}123").roles("admin").build());
    manager.createUser(User.withUsername("sang").password("{noop}123").roles("user").build());
    auth.userDetailsService(manager);
}

二、基于mybatis

MyUserDetailsService

@Service
public class MyUserDetailsService 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.getRolesByUid(user.getId()));
        return user;
    }
}

User类：

public class User implements UserDetails {
    private Integer id;
    private String username;
    private String password;
    private Boolean enabled;
    private Boolean accountNonExpired;
    private Boolean accountNonLocked;
    private Boolean credentialsNonExpired;
    private List<Role> roles = new ArrayList<>();

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                ", enabled=" + enabled +
                ", accountNonExpired=" + accountNonExpired +
                ", accountNonLocked=" + accountNonLocked +
                ", credentialsNonExpired=" + credentialsNonExpired +
                ", roles=" + roles +
                '}';
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<SimpleGrantedAuthority> authorities = new ArrayList<>();
        for (Role role : roles) {
            authorities.add(new SimpleGrantedAuthority(role.getName()));
        }
        return authorities;
    }

    @Override
    public String getPassword() {
        return password;
    }

    @Override
    public String getUsername() {
        return username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return accountNonExpired;
    }

    @Override
    public boolean isAccountNonLocked() {
        return accountNonLocked;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return credentialsNonExpired;
    }

    @Override
    public boolean isEnabled() {
        return enabled;
    }

    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 setAccountNonExpired(Boolean accountNonExpired) {
        this.accountNonExpired = accountNonExpired;
    }

    public void setAccountNonLocked(Boolean accountNonLocked) {
        this.accountNonLocked = accountNonLocked;
    }

    public void setCredentialsNonExpired(Boolean credentialsNonExpired) {
        this.credentialsNonExpired = credentialsNonExpired;
    }

    public Integer getId() {
        return id;
    }

    public List<Role> getRoles() {
        return roles;
    }

    public void setRoles(List<Role> roles) {
        this.roles = roles;
    }
}

Spring Security中的配置：

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(myUserDetailsService);
}
