sqlparser's Introduction

基于mybatis的动态sql解析工具类

背景

我们一般在用mybatis的时候,解析的是写死在sqlmapper文件中的sql语句,而且是在系统启动的时候就解析完成了。 而我在做某个项目的时候需要解析用户输入的sql,系统已经在运行了,用户输入之前也不知道sql的具体内容,所以就把mybatis中相关的代码提取 出来,写了这么一个工具类

使用方法

SqlParser sqlParser = new SqlParser();
String sql = "select * from users WHERE id in (<foreach item=\"id\" index=\"index\" collection=\"idList\" separator=\",\" >#{id}</foreach>)";
List<Long> idList = Arrays.asList(123L,234L,345L);
Map<String, Object> params = new HashMap<String, Object>();
params.put("idList", idList);
SqlData sqlData = sqlParser.parse(sql, params);
System.out.println(sqlData.getSql());//select * from users WHERE id in (  ? , ? , ? )
System.out.println(sqlData.getParamValues());//[123, 234, 345]
