Mybatis批量刪除deleteByIds的用法:

ids要是:"1,2,3"的格式

String ids = "";

for (int i = 0; i < sysTestList.size(); i++) {
    if (i == sysTestList.size() - 1) {
        ids = ids + sysTestList.get(i).getId();
    } else {
        ids = ids + sysTestList.get(i).getId() + ",";
    }
}

sysTestService.deleteByIds(ids);
