hello_test是我的存储过程的名字，在mapper.xml文件中是这么写的

<select id="getPageByProcedure" statementType="CALLABLE" databaseId="oracle">

            {call hello_test(

            #{start,mode=IN,jdbcType=INTEGER},

            #{end,mode=IN,jdbcType=INTEGER},

            #{count,mode=OUT,jdbcType=INTEGER},

            #{emps,mode=OUT,jdbcType=CURSOR,javaType=ResultSet,resultMap=PageEmp}

        )}

        </select>

但是报错报了这样的错误：

java.sql.SQLException: ORA-06550: 第 1 行, 第 7 列:  PLS-00905: 对象 USER1.HELLO_TEST 无效 ORA-06550: 第 1 行, 第 7 列:

这就是存储过程写错了的情况，回到oracle中发现果然是这样的。仔细检查写存储过程的语句，然后改正，就可以正常运行了。

完整报错如下所示：

org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: java.sql.SQLException: ORA-06550: 第 1 行, 第 7 列:
