记一次Mybatis-Plus动态分表DynamicTableNameInnerInterceptor里无法动态替换表名的坑

首先上源码

protected String changeTable(String sql) {
        ExceptionUtils.throwMpe(null == tableNameHandler, "Please implement TableNameHandler processing logic");
        TableNameParser parser = new TableNameParser(sql);//解析出所有语句
        List<TableNameParser.SqlToken> names = new ArrayList<>();
        parser.accept(names::add);根据指定关键词获取表名
        StringBuilder builder = new StringBuilder();
        int last = 0;
        for (TableNameParser.SqlToken name : names) {
            int start = name.getStart();
            if (start != last) {
                builder.append(sql, last, start);
                builder.append(tableNameHandler.dynamicTableName(sql, name.getValue()));
            }
            last = name.getEnd();
        }
        if (last != sql.length()) {
            builder.append(sql.substring(last));
        }
        if (hook != null) {
            hook.run();
        }
        return builder.toString();
    }

 

仅支持一下关键词

 

 

所以如果使用动态表名替换功能时候使用:INSERT IGNORE  类似这样的语句 IGNORE  无法被识别,所以后面跟着的表名也无法识别
