一、创建权限管理服务
1、在service模块下创建子模块service-acl
2、在service_acl模块中引入依赖
1
<dependencies>
2
<dependency>
3
<groupId>com.atguigugroupId>
4
<artifactId>spring_securityartifactId>
5
<version>0.0.1-SNAPSHOTversion>
6
dependency>
7
<dependency>
8
<groupId>com.alibabagroupId>
9
<artifactId>fastjsonartifactId>
10
dependency>
11
dependencies>
3、创建权限管理相关的表
4、复制权限管理接口代码
5、复制整合Spring Security代码
（1）在common模块下创建子模块spring_security
6、编写application.properties配置文件
# 服务端口 server.port=8009 # 服务名 spring.application.name=service-acl # mysql数据库连接 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/guli?serverTimezone=GMT%2B8 spring.datasource.username=root spring.datasource.password=root #返回json的全局时间格式 spring.jackson.date-format=yyyy-MM-dd HH:mm:ss spring.jackson.time-zone=GMT+8 spring.redis.host=192.168.44.132 spring.redis.port=6379 spring.redis.database= 0 spring.redis.timeout=1800000 spring.redis.lettuce.pool.max-active=20 spring.redis.lettuce.pool.max-wait=-1 #最大阻塞等待时间(负数表示没限制) spring.redis.lettuce.pool.max-idle=5 spring.redis.lettuce.pool.min-idle=0 #最小空闲 #配置mapper xml文件的路径 mybatis-plus.mapper-locations=classpath:com/atguigu/aclservice/mapper/xml/*.xml #指定注册中心地址 eureka.client.service-url.defaultZone=http://127.0.0.1:8761/eureka/ #eureka服务器上获取的是服务器的ip地址，否则是主机名 eureka.instance.prefer-ip-address=true #mybatis日志 mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

eureka.instance.prefer-ip-address=true
35

二、开发权限管理接口
1、
获取所有菜单
（1）controller
@RestController @RequestMapping("/admin/acl/permission") @CrossOrigin public class PermissionController { @Autowired private PermissionService permissionService; //获取全部菜单 @GetMapping public R indexAllPermission() { List list = permissionService.queryAllMenu(); return R.ok().data("children",list); } }
1
2
("/admin/acl/permission")
3
4
public class PermissionController {
5
6
7
private PermissionService permissionService;
8
9
//获取全部菜单
10
11
public R indexAllPermission() {
12
List<Permission> list = permissionService.queryAllMenu();
13
return R.ok().data("children",list);
14
}
15
}
（2）service
//获取全部菜单 @Override public List queryAllMenu() { QueryWrapper wrapper = new QueryWrapper<>(); wrapper.orderByDesc("id"); List permissionList = baseMapper.selectList(wrapper); List result = bulid(permissionList); return result; }
1
//获取全部菜单
2
3
public List<Permission> queryAllMenu() {
4
5
QueryWrapper<Permission> wrapper = new QueryWrapper<>();
6
wrapper.orderByDesc("id");
7
List<Permission> permissionList = baseMapper.selectList(wrapper);
8
9
List<Permission> result = bulid(permissionList);
10
return result;
11
}
（3）在Permission实体类添加属性
@ApiModelProperty(value = "层级") @TableField(exist = false) private Integer level; @ApiModelProperty(value = "下级") @TableField(exist = false) private List children; @ApiModelProperty(value = "是否选中") @TableField(exist = false) private boolean isSelect;
1
(value = "层级")
2
(exist = false)
3
private Integer level;
4
5
(value = "下级")
6
(exist = false)
7
private List<Permission> children;
8
9
(value = "是否选中")
10
(exist = false)
11
private boolean isSelect;
（4）编写工具类，根据菜单构建数据
package com.atguigu.aclservice.helper; import com.atguigu.aclservice.entity.Permission; import java.util.ArrayList; import java.util.List; /** * bulid(List treeNodes) { List trees = new ArrayList<>(); for (Permission treeNode : treeNodes) { if ("0".equals(treeNode.getPid())) { treeNode.setLevel(1); trees.add(findChildren(treeNode,treeNodes)); } } return trees; } /** * 递归查找子节点 * @param treeNodes * @return */ public static Permission findChildren(Permission treeNode,List treeNodes) { treeNode.setChildren(new ArrayList()); for (Permission it : treeNodes) { if(treeNode.getId().equals(it.getPid())) { int level = treeNode.getLevel() + 1; it.setLevel(level); if (treeNode.getChildren() == null) { treeNode.setChildren(new ArrayList<>()); } treeNode.getChildren().add(findChildren(it,treeNodes)); } } return treeNode; } }
* 根据权限数据构建菜单数据 *
*/ public class PermissionHelper { /** * 使用递归方法建菜单 * @param treeNodes * @return */ public static List
11
public class PermissionHelper {
12
13
/**
14
* 使用递归方法建菜单
15
* @param treeNodes
16
* @return
17
*/
18
public static List<Permission> bulid(List<Permission> treeNodes) {
19
List<Permission> trees = new ArrayList<>();
20
for (Permission treeNode : treeNodes) {
21
if ("0".equals(treeNode.getPid())) {
22
treeNode.setLevel(1);
23
trees.add(findChildren(treeNode,treeNodes));
24
}
25
}
26
return trees;
27
}
28
29
/**
30
* 递归查找子节点
31
* @param treeNodes
32
* @return
33
*/
34
public static Permission findChildren(Permission treeNode,List<Permission> treeNodes) {
35
treeNode.setChildren(new ArrayList<Permission>());
36
37
for (Permission it : treeNodes) {
38
if(treeNode.getId().equals(it.getPid())) {
39
int level = treeNode.getLevel() + 1;
40
it.setLevel(level);
41
if (treeNode.getChildren() == null) {
42
treeNode.setChildren(new ArrayList<>());
43
}
44
treeNode.getChildren().add(findChildren(it,treeNodes));
45
}
46
}
47
return treeNode;
48
}
2、递归删除菜单
（1）controller
@ApiOperation(value = "递归删除菜单") @DeleteMapping("remove/{id}") public R remove(@PathVariable String id) { permissionService.removeChildById(id); return R.ok(); }
1
(value = "递归删除菜单")
2
("remove/{id}")
3
public R remove( String id) {
4
permissionService.removeChildById(id);
5
return R.ok();
6
}
（2）service
//递归删除菜单 @Override public void removeChildById(String id) { List idList = new ArrayList<>(); this.selectChildListById(id, idList); //把根据节点id放到list中 idList.add(id); baseMapper.deleteBatchIds(idList); } /** * 递归获取子节点 * @param id * @param idList */ private void selectChildListById(String id, List idList) { List childList = baseMapper.selectList(new QueryWrapper().eq("pid", id).select("id")); childList.stream().forEach(item -> { idList.add(item.getId()); this.selectChildListById(item.getId(), idList); }); }
1
//递归删除菜单
2
3
public void removeChildById(String id) {
4
List<String> idList = new ArrayList<>();
5
this.selectChildListById(id, idList);
6
//把根据节点id放到list中
7
idList.add(id);
8
baseMapper.deleteBatchIds(idList);
9
}
10
11
/**
12
*递归获取子节点
13
* @param id
14
* @param idList
15
*/
16
private void selectChildListById(String id, List<String> idList) {
17
List<Permission> childList = baseMapper.selectList(new QueryWrapper<Permission>().eq("pid", id).select("id"));
18
childList.stream().forEach(item -> {
19
idList.add(item.getId());
20
this.selectChildListById(item.getId(), idList);
21
});
22
}
3、给角色分配权限
（1）controller
@ApiOperation(value = "给角色分配权限") @PostMapping("/doAssign") public R doAssign(String roleId,String[] permissionId) { permissionService.saveRolePermissionRealtionShip(roleId,permissionId); return R.ok(); }
1
(value = "给角色分配权限")
2
("/doAssign")
3
public R doAssign(String roleId,String[] permissionId) {
4
permissionService.saveRolePermissionRealtionShip(roleId,permissionId);
5
return R.ok();
6
}
（2）service
//给角色分配权限 @Override public void saveRolePermissionRealtionShip(String roleId, String[] permissionIds) { rolePermissionService.remove(new QueryWrapper().eq("role_id", roleId)); List rolePermissionList = new ArrayList<>(); for(String permissionId : permissionIds) { if(StringUtils.isEmpty(permissionId)) continue; RolePermission rolePermission = new RolePermission(); rolePermission.setRoleId(roleId); rolePermission.setPermissionId(permissionId); rolePermissionList.add(rolePermission); } rolePermissionService.saveBatch(rolePermissionList); }
1
//给角色分配权限
2
3
public void saveRolePermissionRealtionShip(String roleId, String[] permissionIds) {
4
5
rolePermissionService.remove(new QueryWrapper<RolePermission>().eq("role_id", roleId));
6
7
List<RolePermission> rolePermissionList = new ArrayList<>();
8
for(String permissionId : permissionIds) {
9
if(StringUtils.isEmpty(permissionId)) continue;
10
RolePermission rolePermission = new RolePermission();
11
rolePermission.setRoleId(roleId);
12
rolePermission.setPermissionId(permissionId);
13
rolePermissionList.add(rolePermission);
14
}
15
rolePermissionService.saveBatch(rolePermissionList);
16
}
