redis批量删除namespace下的数据的实现步骤
<p>在开发中为了更好的管理数据，对redis进行了分组存储操作，在存值时加了命名空间来实现，如下：@Cacheable的value来实现分组</p><div class="jb51code"><pre class="brush:java;">@Cacheable(value = "config",key ="#comparamid+'_'+#comCode" )/* */
@Query(value = "select * from testwhere comparamid=?1 andconfigcomcode=?2",nativeQuery = true)
public List <test> findByCondition(long comparamid,String comCode );
</pre></div>
<p>redis保存数据如下：</p>
<p style="text-align:center"><img alt="" src="https://img.jbzj.com/file_images/article/202512/2025121111022261.png" /></p>
<p>在批量获取数据时也需要加上namespace的前缀</p>
<p style="text-align:center"><img alt="" src="https://img.jbzj.com/file_images/article/202512/2025121111022263.png" /></p>
<p>因此在java后台批量删除时就可以用一下代码：</p>
<div class="jb51code"><pre class="brush:java;"> @Autowired
private RedisTemplate<String, ?> redisTemplate;
@RequestMapping(value = "/deal", method = RequestMethod.GET)
public Long delByPrefix(final String prefixKey){
//删除config::4开头的redis数据
Set<String> keys = redisTemplate.keys("config::4*");
if(!CollectionUtils.isEmpty(keys)) {
return redisTemplate.delete(keys);
}
return "SUCESS";
}
</pre></div>
<p>当然也可以利用客户端一件删除：</p>
<p style="text-align:center"><img alt="" src="https://img.jbzj.com/file_images/article/202512/2025121111022248.png" /></p>
<p style="text-align:center"><img alt="" src="https://img.jbzj.com/file_images/article/202512/2025121111022297.png" /></p>
