SpringBoot-Security基于数据库的认证

1 . 添加所需要的依赖

2 . 修改pom.xml

</project>

3 . 创建对应表的bean

User

package org.akk.com.securitydb.bean;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
// 这里UserDetails是一个规范，返回的对象将实现了UserDetails的User信息给SecurityConfig，进行解析
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 Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    @Override
    public String getUsername() {
        return username;
    }
    // 账户是否未过期
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    // 账户是否没有被锁定
    @Override
    public boolean isAccountNonLocked() {
        return !locked;
    }

    // 密码是否未过期（凭证是否为过期）
    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    // 是否可用
    @Override
    public boolean isEnabled() {
        return enabled;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    // 返回用户的所用角色
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<SimpleGrantedAuthority> authorities = new ArrayList<>();
        for (Role role : roles) {
            // 这里必须要加ROLE_前缀
            authorities.add(new SimpleGrantedAuthority("ROLE_" + role.getName()));
        }
        return authorities;
    }

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

    public void setPassword(String password) {
        this.password = password;
    }

    public void setEnabled(Boolean enabled) {
        this.enabled = enabled;
    }

    public void setLocked(Boolean locked) {
        this.locked = locked;
    }

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

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

Role

package org.akk.com.securitydb.bean;

public class Role {
    private Integer id;
    private String name;
    private String nameZh;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getNameZh() {
        return nameZh;
    }

    public void setNameZh(String nameZh) {
        this.nameZh = nameZh;
    }

    @Override
    public String toString() {
        return "Role{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", nameZh='" + nameZh + '\'' +
                '}';
    }
}

4 . 创建service,mapper,controller

service

package org.akk.com.securitydb.service;

import org.akk.com.securitydb.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.akk.com.securitydb.bean.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

@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;
    }
}

mapper

package org.akk.com.securitydb.mapper;
import org.akk.com.securitydb.bean.Role;
import org.akk.com.securitydb.bean.User;
import org.apache.ibatis.annotations.Mapper;
import java.util.List;

@Mapper
public interface UserMapper {
    User loadUserByUsername(String username);

    List<Role> getUserRolesById(Integer id);
}

controller

package org.akk.com.securitydb.Controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
    @GetMapping("/hello")
    public String hello(){
        return "hello security!";
    }
}

mybatis

<?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="org.akk.com.securitydb.mapper.UserMapper">
    <select id="loadUserByUsername" resultType="org.akk.com.securitydb.bean.User">
        select * from user where username=#{username};
    </select>

    <select id="getUserRolesById" resultType="org.akk.com.securitydb.bean.Role">
        select * from user_role where uid=#{id};
    </select>
</mapper>

5 . SecurityConfig的配置

package org.akk.com.securitydb.config;

import org.akk.com.securitydb.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    UserService userService;
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userService);
    }

    @Bean
    PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

6 . 测试结果

sql数据

7 . 分角色进入

首先查看role表，user表
role

user
关联表

Controller中添加对应角色api

package org.akk.com.securitydb.Controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@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!";
    }
}

在security配置文件中设置权限

package org.akk.com.securitydb.config;

import org.akk.com.securitydb.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

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

运行测试:

使用root用户测试：root用户拥有dba 和 admin 没有user
user

dba

admin
