要验收项目了，要写数据库文档，一大堆表太费劲了，直接生成一个吧，本来想用个别人的轮子，网上看了几个，感觉效果不怎么好，自己动手写一个吧。抽空再把字典表补充进去就OK了
先看效果：

生成效果

关键代码

            	String prefixTables = "sys_monitor_db_handle.selectDbTabUsedInfo";
   		        String prefixStructure = "sys_monitor_db_handle.selectDbClumInfo";

   		        paramTables.put("tableen", dbname);
   		        String sqlTables = SqlManage.getInstance().getSqlByid(paramTables, prefixTables);
   		        List<Map<String, Object>> tablesList = BaseDao.queryList(sqlTables);

   		        // 生成HTML文档
   		        StringBuilder htmlBuilder = new StringBuilder();
   		        String name="数据库说明文档";
