SpringSecurity学习之基于数据库的用户认证

　　SpringSecurity给我们提供了一套最基本的认证方式，可是这种方式远远不能满足大多数系统的需求。不过好在SpringSecurity给我们预留了许多可扩展的接口给我们，我们可以基于这些接口实现自己的认证方式。

1.1、创建示例数据库

Student表：

create table student
(
    id int auto_increment
        primary key,
    stuName varchar(8) null,
    password varchar(16) null,
    joinTime datetime null,
    clz_id int null
)
;

Classes(班级)表：

create table classes
(
    id int auto_increment
        primary key,
    clz_name varchar(16) not null
)
;

 

1.2、添加相关依赖

compile group: 'mysql', name: 'mysql-connector-java'
compile group: 'org.springframework.security', name: 'spring-security-taglibs'
compile('org.springframework.boot:spring-boot-starter-jdbc')

 

 

二、实现步骤

2.1  定义Student类

package com.bdqn.lyrk.security.study.app.pojo;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.User;

import java.sql.Timestamp;
import java.util.Collection;

public class Student extends User {

    private Timestamp joinTime;

    public Timestamp getJoinTime() {
        return joinTime;
    }

    public void setJoinTime(Timestamp joinTime) {
        this.joinTime = joinTime;
    }

    public Student(String username, String password, Collection<? extends GrantedAuthority> authorities) {
        super(username, password, authorities);
    }

}
