Ibatis中动态获取sqlmap文件中的sql语句

                 String sql = null;

  SqlMapClientImpl sqlmap = (SqlMapClientImpl) this.getSqlMapClient();

  MappedStatement stmt = sqlmap.getMappedStatement("Id");

  Sql stmtSql = stmt.getSql();

  SessionScope sessionScope = new SessionScope();

  sessionScope.setSqlMapClient(this.getSqlMapClient());

  StatementScope  statementScope = new StatementScope(sessionScope);

  statementScope.setStatement(stmt);

  sql =  stmtSql.getSql(statementScope, obj);

  System.out.println(sql);
