权限管理2-开发权限管理接口
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
<dependencies>
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>spring_security</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
</dependency>
</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
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
二、开发权限管理接口
1、获取所有菜单
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<Permission> children;
@ApiModelProperty(value = "是否选中")
@TableField(exist = false)
private boolean isSelect;
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;
/**
* <p>
* 根据权限数据构建菜单数据
* </p>
*/
public class PermissionHelper {
/**
* 使用递归方法建菜单
* @param treeNodes
* @return
*/
public static List<Permission> bulid(List<Permission> treeNodes) {
List<Permission> 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<Permission> treeNodes) {
treeNode.setChildren(new ArrayList<Permission>());
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;
}
}
controller层:
@RestController
@RequestMapping("/admin/acl/permission")
@CrossOrigin
public class PermissionController {
@Autowired
private PermissionService permissionService;
//获取全部菜单
@GetMapping
public R indexAllPermission() {
List<Permission> list = permissionService.queryAllMenu();
return R.ok().data("children",list);
}
}
service层:
//获取全部菜单
@Override
public List<Permission> queryAllMenu() {
QueryWrapper<Permission> wrapper = new QueryWrapper<>();
wrapper.orderByDesc("id");
List<Permission> permissionList = baseMapper.selectList(wrapper);
List<Permission> result = bulid(permissionList);
return result;
}
2、递归删除菜单
controller层:
@ApiOperation(value = "递归删除菜单")
@DeleteMapping("remove/{id}")
public R remove(@PathVariable String id) {
permissionService.removeChildById(id);
return R.ok();
}
service层:
//递归删除菜单
@Override
public void removeChildById(String id) {
List<String> 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<String> idList) {
List<Permission> childList = baseMapper.selectList(new QueryWrapper<Permission>().eq("pid", id).select("id"));
childList.stream().forEach(item -> {
idList.add(item.getId());
this.selectChildListById(item.getId(), idList);
});
}
3、给角色分配权限
controller层:
@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();
}
service层:
//给角色分配权限
@Override
public void saveRolePermissionRealtionShip(String roleId, String[] permissionIds) {
rolePermissionService.remove(new QueryWrapper<RolePermission>().eq("role_id", roleId));
List<RolePermission> 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);
}
