@wenshao 你好，想跟你请教个问题：我Java jdbc代码执行删除存储过程sql语句，但是报了错误
java.sql.SQLException: sql injection violation, class com.alibaba.druid.sql.ast.statement.SQLDropProcedureStatement not allow : DROP PROCEDURE IF EXISTS CP_PayCalc1
at com.alibaba.druid.wall.WallFilter.check(WallFilter.java:714)

Exception in thread "main" com.mchr.exception.SqlException: SQL:1 param:[] sql: DROP PROCEDURE IF EXISTS CP_PayCalc1 sql injection violation, class com.alibaba.druid.sql.ast.statement.SQLDropProcedureStatement not allow : DROP PROCEDURE IF EXISTS CP_PayCalc1

最后，我把filter中的wall去掉好了，但是这样就不能进行预防sql注入了，请问有没有更好的解决办法？
