2 菜单项接口

从数据库加载菜单项，不写死在 router

2.1 sql 测试

SELECT * FROM menu m1,menu m2,hr_role hrr,menu_role mr 
where 
m1.id = m2.parentId and hrr.hrid=10 
and hrr.rid=mr.rid and mr.mid=m2.id and
m2.enabled=true order by m1.id,m2.id;

---

SELECT distinct m1.*,m2.id as id2,m2.component as component2,
m2.enabled as enabled2,
m2.iconCls as iconCls2,m2.keepAlive as keepAlive2,m2.name as name2,
m2.parentId as parentId2,m2.requireAuth as requireAuth2,m2.path as path2
FROM menu m1,menu m2,hr_role hrr,menu_role mr 
where
 m1.id = m2.parentId and hrr.hrid=10 
 and hrr.rid=mr.rid and mr.mid=m2.id and
m2.enabled=true order by m1.id,m2.id;

2.2 测试

• MenuService

package com.tzb.service;

import com.tzb.mapper.MenuMapper;
import com.tzb.model.Hr;
import com.tzb.model.Menu;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class MenuService {

    @Autowired
    MenuMapper menuMapper;

    public List<Menu> getMenusByHrId() {
        return menuMapper.getMenusByHrId(
                ((Hr)SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getId());
    }
}

• Controller

package com.tzb.controller;

import com.tzb.model.Menu;
import com.tzb.service.MenuService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/system/config")
public class SystemConfigController {

    @Autowired
    MenuService menuService;

    @GetMapping("/menu")
    public List<Menu> getMenusByHrId(){
        return menuService.getMenusByHrId();
    }

}
