权限系统说明+代码
系统权限
说明
- 功能权限（就是常用的RBAC那一套，登录->控制到按钮级别的权限系统）
- 数据权限 (根据不用用户，如一个园区分为多家企业，每家企业看到的数据内容不同，园区内不同领导分管不同的多家企业)
功能权限

权限框架
spring security
自定义security策略，初步的权限校验，拦截所有的请求，swagger页面和接口无法访问
@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
// 跨域检测
.antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
// 对任何请求都进行权限验证
.anyRequest().authenticated()
;
}
}指定页面放开
以swagger和阿里druid连接池监控工具为例，添加以下内容后，swagger内容将正常显示
@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
// @formatter:off
http
.authorizeRequests()
// 跨域检测
.antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
// 放行的url
.antMatchers("/v3/api-docs/**", "/webjars/**", "/druid/**", "/configuration/ui", "/swagger-resources/**", "/css/**", "/js/**", "/plugins/**", "/favicon.ico", "/doc.html", "/static/**").permitAll()
// 对任何请求都进行权限验证
.anyRequest().authenticated()
;
// @formatter:on
}
}
将写死的需要放开的url添加至yml中
# 配置的url

});
}
}// 在开放配置中添加上述配置的url
@Configuration

permitAllUrlProperties.getIgnoreUrls().forEach(ignoreUrl -> registry.antMatchers(ignoreUrl).permitAll());
// 对任何请求都进行权限验证
registry.anyRequest().authenticated()
.and().csrf().disable();
// @formatter:on

资源访问权限
新增PermissionService用于接口指定访问权限
在WebSecurityConfig中添加注解@EnableGlobalMethodSecurity(prePostEnabled=true)
如果用户的权限列表中不包含该权限则不允许访问。一般用于按钮级别权限的控制。
package com.lyc.admin.oauth.service;
import cn.hutool.core.util.ArrayUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Component;
import org.springframework.util.PatternMatchUtils;
import org.springframework.util.StringUtils;
import java.util.Collection;
@Slf4j
@Component("pms")
public class PermissionService {
/**
* 判断接口是否有任意xxx，xxx权限
*
* @param permissions 权限
* @return {boolean}
*/
public boolean hasPermission(String... permissions) {
if (ArrayUtil.isEmpty(permissions)) {
return false;
}
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication == null) {
return false;
}
Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();
return authorities.stream()
.map(GrantedAuthority::getAuthority)
.filter(StringUtils::hasText)
.anyMatch(x -> PatternMatchUtils.simpleMatch(permissions, x));
}
}测试，添加两个接口，一个接口含有permission中的字符串，一个没有。@PreAuthorize 使用时如果没有权限将不会进入方法。
postman调用结果
统一403返回格式
// enum
FORBIDDEN_403(403, "缺少资源访问权限!"),
// 403自定义处理
public class Http403AccessDeniedEntryPoint implements AccessDeniedHandler {
@Override
public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException, ServletException {
ResponseUtil.out(response, R.fail(SystemCode.FORBIDDEN_403));
}
}
// 加入配置
HttpSecurity.exceptionHandling().accessDeniedHandler(new Http403AccessDeniedEntryPoint());
权限控制 没有权限,方法依然执行但是不会返回
使用场景，比如只允许用户查询自己的用户信息。
对返回结果进行过滤
对请求参数进行过滤
oauth2.0
数据权限
实现方式
以下使用的方式是拦截sql后自定义组装来实现数据过滤
代码实现1
定义一个注解DataScope用于判断哪些类、方法需要进行数据过滤。当然你也可以稍微修改下，默认对数据进行过滤，指定类、方法不过滤
package cn.allbs.allbsjwt.config.annotation;
import java.lang.annotation.Documented;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.ElementType.TYPE;
@Target({METHOD, TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface DataScope {
/**
* 当进行过滤时主表中代表企业id的字段
*/
String unitField() default "ent_id";
/**
* 是否进行数据过滤
*/
boolean filterData() default true;
/**
* 忽略的表名
*
* @return 不进行数据过滤的表名的集合
*/
String[] ignoreTables() default {"sys_file"};
}定义一个实体类用户临时储存sql过滤中需要使用的参数信息
@Data
@EqualsAndHashCode(callSuper = true)
@RequiredArgsConstructor
public class DataScopeParam extends HashMap {
/**
* 企业筛选字段名称（比如某个表中并未使用其他表通用的字段ent_id进行区分企业）
*/
private String unitField;
/**
* 企业数据范围
*/
private Set<Long> entIdList;
/**

/**

*/
private List<String> ignoreTables;
}

}添加DataScopeParamContentHolder用户储存需要过滤数据的配置信息

}
private static final ThreadLocal<DataScopeParam> THREAD_PMS_HOLDER = new TransmittableThreadLocal<>();

}
}添加拦截器DataScopeAnnotationIntercept用于拦截方法级别的注解，处理添加了上方自定义注解的方法,缓存自定义注解中的配置

dataScopeAnnotationClassResolver = new DataScopeAnnotationClassResolver();
}
@Nullable
@Override
public Object invoke(@NotNull MethodInvocation methodInvocation) throws Throwable {
DataScopeParam paramKey = dataScopeAnnotationClassResolver.findKey(methodInvocation.getMethod(), methodInvocation.getThis());
DataScopeParamContentHolder.set(paramKey);
try {
return methodInvocation.proceed();
} finally {
DataScopeParamContentHolder.clear();
}
}
}添加配置将上述内容注册进去
@Configuration
public class DataScopeInitConfig {
@Bean
public Advisor generateAllDataScopeAdvisor() {
DataScopeAnnotationIntercept intercept = new DataScopeAnnotationIntercept();
DataScopeAnnotationAdvisor advisor = new DataScopeAnnotationAdvisor(intercept, DataScope.class);
advisor.setOrder(Ordered.HIGHEST_PRECEDENCE);
return advisor;
}
}最后根据配置内容信息对应的处理sql，这个类是关键，前面所有内容都是为他服务，如果只是想简单点写死代码直接使用该类就可以了

假设用户admin具备企业1、2、3的权限。用户test具备企业3、4、5的权限
企业数据测试表cm_ent_data
create table cm_ent_data
(
id bigint auto_increment comment '主键'
primary key,
ent_id bigint not null comment '企业id',
description varchar(200) null comment '说明'

comment '用户数据测试的表';

| 5 | 5 | 企业5的测试数据1号 |
| 6 | 2 | 企业2的测试数据2号 |
| 7 | 3 | 企业3的测试数据2号 |
假设企业2、3分别有2条数据，企业1、4、5分别只有一条数据
这三张表生成对应的controller、service、mapper文件
建议用easycode插件，具体使用方法和模版（生成后的内容需要更新实际情况改改）
📃 关联文档
登录时查询用户关联的企业列表并缓存，当然如果怕影响登录速度，可以在登录后执行一个异步方法进行相关操作
具体添加的代码见对应的git提交即可，总之这一步主要目的就是让权限系统中的用户信息中含有该用户的关联企业列表
启动项目后进行测试
未加dataScope注解查询企业数据测试表，结果显示查出全部数据
添加注解测试，用户admin关联企业1、2、3查询结果符合期望
现在有个需求，根据前端需要查询的企业进行数据筛选
增加一个Holder用于储存当前查询ent_id列表
package cn.allbs.allbsjwt.config.datascope;
import com.alibaba.ttl.TransmittableThreadLocal;
import lombok.experimental.UtilityClass;
import java.util.Set;
@UtilityClass
public class CurrentEntIdSearchContextHolder {
private final ThreadLocal<Set<Long>> THREAD_LOCAL_ENT_LIST = new TransmittableThreadLocal<>();
/**
* 设置当前header中的企业列表
*
* @param entIdList 需要查询的企业列表
*/
public void setEntIdList(Set<Long> entIdList) {
THREAD_LOCAL_ENT_LIST.set(entIdList);
}
/**
* 获取header中的企业列表
*
* @return 企业列表
*/
public Set<Long> getEntIdList() {
return THREAD_LOCAL_ENT_LIST.get();
}
public void clear() {
THREAD_LOCAL_ENT_LIST.remove();
}
}
添加过滤器，将前端传输的数据储存起来
package cn.allbs.allbsjwt.config.datascope;
import cn.allbs.allbsjwt.config.constant.CommonConstants;
import cn.hutool.core.convert.Convert;
import cn.hutool.core.util.StrUtil;
import lombok.SneakyThrows;
import lombok.extern.slf4j.Slf4j;
import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.GenericFilterBean;
import javax.servlet.FilterChain;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Set;
@Slf4j
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class EntIdContextHolderFilter extends GenericFilterBean {
@Override
@SneakyThrows
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse) servletResponse;
String entIdListStr = request.getHeader(CommonConstants.ENT_ID_LIST);
if (StrUtil.isNullOrUndefined(entIdListStr)) {
CurrentEntIdSearchContextHolder.clear();
} else {
Set<Long> entIdList = Convert.toSet(Long.class, entIdListStr);
CurrentEntIdSearchContextHolder.setEntIdList(entIdList);
log.debug("获取header中的企业列表为:{}", entIdList);
}
filterChain.doFilter(request, response);
CurrentEntIdSearchContextHolder.clear();
}
}在UnitDataPermissionInterceptor中添加代码过滤用户查询的企业列表
// 获取header中的待过滤的企业列表
Set<Long> entIdList = CurrentEntIdSearchContextHolder.getEntIdList();
if (entIdList != null) {
if (dataScopeParam == null) {
dataScopeParam = new DataScopeParam("ent_id", entIdList, true, CollUtil.newArrayList("sys_file"));
} else {
// 查询交集
Set<Long> permissionEntList = dataScopeParam.getEntIdList();
dataScopeParam.setFilterField(true);
dataScopeParam.setEntIdList(entIdList.stream().filter(permissionEntList::contains).collect(Collectors.toSet()));
}
}
进行测试
在添加dataScope的情况下只查询到企业符合期望
去掉datascope进行测试
没有企业3的数据符合预期
