ruoyi若依框架@DataScope注解使用以及碰到的一些问题

1️⃣、项目使用场景：

根据不同角色的登录用户，查看不同的列表数据

2️⃣、思路

因为使用的是ruoyi若依框架，所以第一个想到的就是使用@DataScope注解，用来控制数据权限的

3️⃣、具体使用方法

使用起来很简单：
1、在你的实现类的方法上加上该注解 @DataScope(deptAlias = “d”)

	@Override
    @DataScope(deptAlias = "d")
    public List<BackupQueueManage> selectBackupQueueManageList(BackupQueueManage backupQueueManage) {
    
        List<BackupQueueManage> backupQueueManages = backupQueueManageMapper.selectBackupQueueManageList(backupQueueManage);
        for (BackupQueueManage manage : backupQueueManages) {
    
            String linkScriptId = manage.getLinkScriptId();
            if(StringUtils.isBlank(linkScriptId)){
    
                linkScriptId = configService.selectConfigByKey(DB2_BACKUP_SCRIPT);
            }
            ......
        }
        return backupQueueManages;
    }

2、在mybatis的xml文件中加上 ${params.dataScope}

<sql id="selectBackupQueueManageVo">
        select queue_id, queue_name from backup_queue_manage d
    </sql>
<
select id="selectBackupQueueManageList" parameterType="BackupQueueManage" resultMap="BackupQueueManageResult">
        <include refid="selectBackupQueueManageVo"/>
        <where>  
            <if test="queueName != null and queueName != ''"> and queue_name like concat('%', #{queueName}, '%')</if>
            <if test="scheduleType != null and scheduleType != ''"> and schedule_type = #{scheduleType}</if>
            <if test="executorTime != null and executorTime != ''"> and executor_time = #{executorTime}</if>
            <if test="dbIds != null and dbIds != ''"> and db_ids = #{dbIds}</if>
            <if test="jobId != null "> and job_id = #{jobId}</if>
            <if test="isOpen != null and isOpen != ''"> and is_open = #{isOpen}</if>
            <if test="dbType != null and dbType != ''"> and db_type = #{dbType}</if>

            <!-- 数据范围过滤 -->
            ${params.dataScope}
        </where>
    </select>

4️⃣、遇到的问题

问题1、我们访问页面的时候，发现如下报错信息

Error querying database. Cause: java.sql.SQLSyntaxErrorException: Unknown column 'd.dept_id' in 'IN/ALL/ANY subquery' 
The error may exist in URL [jar:file:/opt/hidata/hidbm-vue/paas.jar!/BOOT-INF/classes!/mapper/BackupQueueManageMapper.xml] ### 
The error may involve com.hidata.devops.selfops.mapper.BackupQueueManageMapper.selectBackupQueueManageList-Inline ### The error occurred while setting parameters 
SQL: SELECT count(0) FROM backup_queue_manage WHERE (d.dept_id IN (SELECT dept_id FROM sys_dept WHERE dept_id = 100 OR find_in_set(NULL, ancestors)))
 ### Cause: java.sql.SQLSyntaxErrorException: Unknown column 'd.dept_id' in 'IN/ALL/ANY subquery' ; bad SQL grammar []; 
nested exception is java.sql.SQLSyntaxErrorException: Unknown column 'd.dept_id' in 'IN/ALL/ANY subquery'

原因是因为：我们的表中没有加dept_id字段

问题2、报错信息如下：

 Error querying database. Cause: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; 
check the manual that corresponds to your MySQL server version for the right syntax to use near 'IN 
( SELECT dept_id FROM sys_dept WHERE dept_id = 101 or find_in_set( 101 , ance' at line 4  The error may exist in URL
 [jar:file:/opt/hidata/hidbm-vue/paas.jar!/BOOT-INF/classes!/mapper/BackupQueueManageMapper.xml]  The error may involve
 com.hidata.devops.selfops.mapper.BackupQueueManageMapper.selectBackupQueueManageList-Inline  The error occurred while 
 setting parameters  SQL: select count(0) from ( select queue_id, queue_name, schedule_type, executor_time, db_ids, job_id, create_time, is_open,link_script_id
 ,db_type, create_by, update_time, update_by from backup_queue_manage WHERE (.dept_id IN ( SELECT dept_id FROM sys_dept WHERE dept_id = 101 or find_in_set( 101 , ancestors ) )) ) tmp_count  Cause: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IN ( SELECT dept_id FROM sys_dept WHERE dept_id = 101 or find_in_set( 101 , ance' at line 4 ; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for 
the right syntax to use near 'IN ( SELECT dept_id FROM sys_dept WHERE dept_id = 101 or find_in_set( 101 , ance' at line 4

通过报错信息，我们发现这么一句 WHERE (.dept_id ，说明sql语句中没有加别名，只要加上即可：select queue_id, queue_name from backup_queue_manage d
