spring-Security《一》

源码介绍：

public interface UserDetailsService {
    UserDetails loadUserByUsername(String var1) throws UsernameNotFoundException;
}

 里面返回一个UserDetails，来看下UserDetails里面是什么

public interface UserDetails extends Serializable {
    Collection<? extends GrantedAuthority> getAuthorities();

    String getpassword();  密码

    String getUsername(); 用户名

    boolean isAccountNonExpired(); 账号是否被过期

    boolean isAccountNonLocked();账号是否被锁定

    boolean isCredentialsNonExpired(); 证书(密码)是否过期

    boolean isEnabled();账号是否被启用
}

 UserDetails也是个接口，那么他肯定有实现类

里面果然有个User去实现它

 

 看下User是什么小编

 

 属性是与接口对应，有两个构造函数

用户名，密码，授权
    public User(String username, String password, Collection<? extends GrantedAuthority> authorities) {
        this(username, password, true, true, true, true, authorities);
    }

就是那一堆属性构造方法了
    public User(String username, String password, boolean enabled, boolean accountNonExpired, boolean credentialsNonExpired, boolean accountNonLocked, Collection<? extends GrantedAuthority> authorities) {
        if (username != null && !"".equals(username) && password != null) {
            this.username = username;
            this.password = password;
            this.enabled = enabled;
            this.accountNonExpired = accountNonExpired;
            this.credentialsNonExpired = credentialsNonExpired;
            this.accountNonLocked = accountNonLocked;
            this.authorities = Collections.unmodifiableSet(sortAuthorities(authorities));
        } else {
            throw new IllegalArgumentException("Cannot pass null or empty values to constructor");
        }
    }
