Spring Security 连接数据库实现认证

Spring Security中的UsernamePasswordAuthenticationFilter是用于处理基于表单的登录请求。
UserDetails定义了Spring Security中用户的一些基本信息。

这里通过实现UserDetails，继承UserDetailsService实现loadUserByUsername方法来实现。
实体SysUser:

package cn.sivan.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.security.core.GrantedAuthority;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class SysRole implements GrantedAuthority {
    private Integer id;
    private String roleName;
    private String roleDesc;

    @Override
    public String getAuthority() {
        return roleName;
    }
}

实体SysUser:

package cn.sivan.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.Collection;
import java.util.List;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class SysUser implements UserDetails {
    private Integer id;
    private String username;
    private String password;
    private Integer status;
    private List<SysRole> roles;

    /**
     * 用户的权限信息，通常使用角色表示
     * @return
     */
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return roles;
    }

    /**
     * 账号是否过期
     * @return
     */
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    /**
     * 账号是锁定
     * @return
     */
    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    /**
     * 密码是否过期
     * @return
     */
    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    /**
     * 账号是否可用
     * @return
     */
    @Override
    public boolean isEnabled() {
        return status == 1;
    }
}

使用mybatis，mapper实例：

package cn.sivan.mapper;

import cn.sivan.pojo.SysRole;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;

import java.util.List;

@Component
public interface RoleMapper {

    @Select("select r.id,r.ROLE_NAME roleName,r.ROLE_DESC roleDesc " +
            "from sys_role r,sys_user_role ur  " +
            "where r.ID=ur.RID and ur.UID=#{uid}")
    List<SysRole> findRoleByUid(Integer uid);

}

package cn.sivan.mapper;

import cn.sivan.pojo.SysUser;
import org.apache.ibatis.annotations.Many;
import org.apache.ibatis.annotations.Result;
import org.apache.ibatis.annotations.Results;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Component;

import java.util.List;

@Component
public interface UserMapper {

    @Select("select * from sys_user u where u.username=#{username}")
    @Results({
            @Result(id = true, property = "id", column = "id"),
            @Result(property = "roles", column = "id", javaType = List.class,
                    many = @Many(select = "cn.sivan.mapper.RoleMapper.findRoleByUid"))
    })
    SysUser findUserByUsername(String username);
}

实现UserDetailsService：

package cn.sivan.service.impl;

import cn.sivan.mapper.UserMapper;
import cn.sivan.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Component;

@Component
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserDetails user = userMapper.findUserByUsername(username);

        if (user == null) {
            throw new UsernameNotFoundException("不存在该用户!");
        }
        return user;
    }
}

SpringSecurity配置：

package cn.sivan.config;

import cn.sivan.service.LoginValidateAuthenticationProvider;
import cn.sivan.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
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.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@EnableWebSecurity
public class SpringSecurity extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserService userService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //指定userDetailsService
        auth.userDetailsService(userService).passwordEncoder(new BCryptPasswordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers( "/favicon.ico").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                    .loginPage("/login/user")
                    .loginProcessingUrl("/login")
                    .defaultSuccessUrl("/")
                    .failureUrl("/login/failure")
                    .permitAll()
                .and()
                .logout()
                    .logoutSuccessUrl("/login/user")
                    .logoutUrl("/logout")
                    .invalidateHttpSession(true)
                    .permitAll()
                .and()
                .csrf()
                    .disable();
    }
}
