myBatis 调用 Oracle 存储过程，报错，求解答

Posted 2023-04-13

调用时报错：存储过程名没有声明，可是我明明已经定义了。
错误信息：
java.lang.Exception: org.springframework.jdbc.BadSqlGrammarException:
### Error querying database. Cause: java.sql.SQLException: ORA-06550: 第 1 行, 第 7 列:
PLS-00201: 必须声明标识符 'PROC_TEST'
ORA-06550: 第 1 行, 第 7 列:
PL/SQL: Statement ignored

存储过程定义：
create or replace PROCEDURE proc_test(inWorkDate IN VARCHAR, outWorkDay OUT varchar) IS
begin
outWorkDay := to_char(to_date(inWorkDate,'yyyy-mm-dd'),'yyyy-mm-dd');
dbms_output.put_line(outWorkDay);
END proc_test;
我已经解决了，是因为调用的时候必须加上数据库用户名

参考技术A 你的语句有问题 在oracle客户端执行过了 再往mybatis里面贴 参考技术B 1.确实有proc_test这个过程吗？
2.你是否忘记加属主？

MyBatis - 使用自定义对象调用存储过程

我想在Spring-boot应用程序中使用Mybatis 3调用带有自定义对象的oracle存储过程。我没有任何关于如何做的例子。我已经有一个使用标准JDBC调用该过程的方法，我想将其转换为MyBatis。

此外，当我使用ojdbc7.jar时，StructDescriptor类和ARRAY类显示为已弃用。有没有其他更好的方法来实现这一目标？任何帮助将不胜感激。提前致谢。

答案

弃用是为了阻止做整件事：使用Oracle Arrays和Structs，但无论如何它都会起作用。

简而言之，从Java类型到Oracle自定义类型的映射需要使用自定义Mybatis TypeHandler。类型处理程序中的代码基本上是JDBC。当涉及操纵数组和结构时，它强烈依赖于DB供应商的驱动程序API（根本不是标准的）。

设置Mybatis有很多内容，所以这里有特定的部分。

以下抽象类允许将java Array / Collection映射到Oracle Array / Table类型。只需在具体实现中指定Oracle端的类型名称：例如：List < - > TYPE ARRAY_INT AS TABLE OF NUMBER。

import java.sql.Array;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

    protected abstract String getSqlType();

            stmt.setArray(index, array);
            LOGGER.debug("statement array Set");
        
    

    protected ARRAY createArray(final OracleConnection oracleConnection, final String type, final Object[] javaArray) throws SQLException 
        return oracleConnection.createARRAY(type, javaArray);
    

    @Override
