MyBatis中，注解构建的动态SQL，多Where拼接时中间默认是and,如何修改为or

Question

如题，比如我实现如下拼接

for (Object key : key_values){
                        WHERE("(article.title LIKE '%"+key.toString()+"%' OR article.content LIKE '%"+key.toString()+"%')");
                    }

SQL 输出如下 中间链接为AND

SELECT user.nickname,user.userIcon,article.*
FROM article,user
WHERE (user.openID = article.openID) 
AND ((article.title LIKE '%sql%' OR article.content LIKE '%sql%') AND (article.title LIKE '%啊%' OR article.content LIKE '%啊%'))

而我想要的是如下结果,中间链接为OR

SELECT user.nickname,user.userIcon,article.*
FROM article,user
WHERE (user.openID = article.openID) 
AND ((article.title LIKE '%sql%' OR article.content LIKE '%sql%') OR (article.title LIKE '%啊%' OR article.content LIKE '%啊%'))
