spring security笔记一

创建SecurityConfig类，加上@Configuration注解

添加授权方法：

/**
 * 访问路径授权
 * 
 * @param http
 * @return
 * @throws Exception
 */
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
    // 自定义登录页面
    http.formLogin().loginProcessingUrl("/person/index").successForwardUrl("/index").loginPage("/login/login.html");
    // 获取权限集合
    List<Authority> list = this.authorityService.getAllAuthorityAndMatchResource();
    if (!CollectionUtils.isEmpty(list) && list.size() > 0) {
        list.forEach(authority -> {
            try {
                // 获取权限路径
                List<String> resourceUrl = authority.getResourceUrl();
                if (!CollectionUtils.isEmpty(resourceUrl) && resourceUrl.size() > 0) {
                    // 设置权限
                    http.authorizeHttpRequests((author) -> {
                        author.antMatchers(CommonUtils.listToArray(resourceUrl)).hasRole(authority.getCode());
                    }).httpBasic();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        });
    }
    // 登录页面不拦截
    http.authorizeRequests().antMatchers("/login/login.html").permitAll();
    return http.csrf().disable().build();
}
资源权限查询和结果映射：

<select id="getAllAuthorityAndMatchResource" resultMap="authAndMathResResult">
    select t.*, r.url as url
    from authority t
             right join resource r on t.id = r.authority_id and r.status = 1
    where t.status = 1
    group by t.code, r.url
</select>

<resultMap id="authAndMathResResult" type="authority">
    <id property="id" column="id"/>
    <result property="code" column="code"/>
    <result property="describes" column="describes"/>
    <result property="status" column="status"/>
    <collection property="resourceUrl" ofType="String" javaType="java.util.List">
        <result column="url"/>
    </collection>
</resultMap>
忽略权限的地址：

@Bean
public WebSecurityCustomizer webSecurityCustomizer() {
    return (web) -> web.ignoring().antMatchers("/", "/index");
}
用户认证，从数据库拉取出来放到内存：

/**
 * 用户认证
 * 
 * @param //encoder 加密
 * @return
 */
@Bean
public InMemoryUserDetailsManager userDetailsService(PasswordEncoder encoder) {
    // 获取用户信息
    List<UserInfo> userInfoList = this.personService.structLoginInfo(null);
    List<UserDetails> userDetailsList = new ArrayList<>();
    userInfoList.forEach(userInfo -> {
        userDetailsList.add(User.withUsername(userInfo.getLoginName()).password(userInfo.getPassword())
            .roles(userInfo.getAuthorityCode()).build());
    });
    return new InMemoryUserDetailsManager(userDetailsList);
}
继承加密类并实现：

import org.pro.service.encoder.PasswordEncoderService;
import org.pro.utils.CommonUtils;
import org.springframework.stereotype.Service;

/**
 * @author Administrator
 */
@Service("passwordEncoderService")
public class PasswordEncoderServiceImpl implements PasswordEncoderService {
    @Override
    public String encode(CharSequence rawPassword) {
        if (rawPassword != null) {
            String str = rawPassword.toString();
            return CommonUtils.doubleEncryption(str);
        }
        return "";
    }

    @Override
    public boolean matches(CharSequence rawPassword, String encodedPassword) {
        if (rawPassword != null && encodedPassword != null) {
            return encodedPassword.equals(CommonUtils.doubleEncryption(rawPassword.toString()));
        }
        return false;
    }
}
用户数据类：

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

/**
 * @author Administrator
 */
@Data
@NoArgsConstructor
@AllArgsConstructor
public class UserInfo {

    private Long userId;
    private String loginName;
    private String password;
    private Long roleId;
    private String authorityCode;

}
