代码 角色 更新菜单
代码如下

    @Override
    public int update(Role data) {
        List<String> ids = new ArrayList<>();
        if (data != null && data.getMenuIds() != null) {
            if (Strings.isNotBlank(data.getMenuIds())) {
                ids = Arrays.asList(data.getMenuIds().split(","));
            }
            //清除已有关系
            Role tmpData = this.fetch(data.getId());
            this.fetchLinks(tmpData, "menus");
            dao().clearLinks(tmpData, "menus");
        }
        if (ids != null && ids.size() > 0) {
            Criteria cri = Cnd.cri();
            cri.where().andInStrList("id", ids);
            List<Menu> menuList = menuService.query(cri);
            data.setMenus(menuList);
        }
        int count = dao().update(data);
        dao().insertRelation(data, "menus");
        return count;
    }

有没有办法能提升一下 角色更新菜单的速度呢

加个事务包起来试试

加了事物 还是执行很慢19秒

    @Override
    public int update(Role data) {
        final int[] count = {0};
        // Begin transaction
        Trans.exec(new Atom() {
            @Override
            public void run() {
                List<String> ids = new ArrayList<>();
                if (data != null && data.getMenuIds() != null) {
                    if (Strings.isNotBlank(data.getMenuIds())) {
                        ids = Arrays.asList(data.getMenuIds().split(","));
                    }
                    //清除已有关系
                    Role tmpData = fetch(data.getId());
                    fetchLinks(tmpData, "menus");
                    dao().clearLinks(tmpData, "menus");
                }
                if (ids != null && ids.size() > 0) {
                    Criteria cri = Cnd.cri();
                    cri.where().andInStrList("id", ids);
                    List<Menu> menuList = menuService.query(cri);
                    data.setMenus(menuList);
                }
                count[0] = dao().update(data);
                dao().insertRelation(data, "menus");
            }
        });
        // End transaction
        return count[0];
    }

酱紫 还是 19秒

    @Override
    public int update(Role data) {
        final int[] count = {0};
        List<String> ids = new ArrayList<>();
        if (data != null && data.getMenuIds() != null) {
            if (Strings.isNotBlank(data.getMenuIds())) {
                ids = Arrays.asList(data.getMenuIds().split(","));
            }
            //清除已有关系
            Role tmpData = fetch(data.getId());
            fetchLinks(tmpData, "menus");
            dao().clearLinks(tmpData, "menus");
        }
        if (ids != null && ids.size() > 0) {
            Criteria cri = Cnd.cri();
            cri.where().andInStrList("id", ids);
            List<Menu> menuList = menuService.query(cri);
            data.setMenus(menuList);
        }
        // Begin transaction
        Trans.exec(new Atom() {
            @Override
            public void run() {
                count[0] = dao().update(data);
                dao().insertRelation(data, "menus");
            }
        });
        // End transaction
        return count[0];
    }

能不能分别计时一下, 感觉是关联关系一条一条顺序插入了

改成如下计时

    /**
     * 更新角色
     *
     * @param data
     * @return
     */
    @Override
    public int update(Role data) {
        long temp = System.currentTimeMillis();
        List<String> ids = new ArrayList<>();
        if (data != null && data.getMenuIds() != null) {
            if (Strings.isNotBlank(data.getMenuIds())) {
                ids = Arrays.asList(data.getMenuIds().split(","));
            }
            //清除已有关系
            Role tmpData = this.fetch(data.getId());
            this.fetchLinks(tmpData, "menus");
            System.out.println("查询关系耗时:" + (System.currentTimeMillis() - temp) / 1000.0 + "秒");
            dao().clearLinks(tmpData, "menus");
            System.out.println("清除关系耗时:" + (System.currentTimeMillis() - temp) / 1000.0 + "秒");
        }
        if (ids != null && ids.size() > 0) {
            Criteria cri = Cnd.cri();
            cri.where().andInStrList("id", ids);
            List<Menu> menuList = menuService.query(cri);
            data.setMenus(menuList);
        }
        int count = dao().update(data);
        System.out.println("更新耗时:" + (System.currentTimeMillis() - temp) / 1000.0 + "秒");
        dao().insertRelation(data, "menus");
        System.out.println("多对多插入耗时:" + (System.currentTimeMillis() - temp) / 1000.0 + "秒");
        return count;
    }

角色和菜单是多对多关系 是不是因为多对多 导致遍历 比较慢

    @ManyMany(from = "role_id", relation = "sys_role_menu", to = "menu_id")
    protected List<Menu> menus;

200条, 看上去是批量插入, 应该不会慢呀

SELECT * FROM sys_menu  WHERE id IN

这个表数据量没多少吧? 难道是它慢?

sys_menu 一共200多点 数据

找到问题 数据库 连接是 服务器的 会很慢 连接本地 就没问题......
我又水了一个贴
