Java 如何从oracle过程到SimpleJDBCall获取价值

我已经使用spring和procedure成功地使用Simplejdbccall保存了详细信息，但是我需要从procedure返回一个值，并在java代码中获取它

public void saveNamedDrivers(QuotationDO quotationDO) {
    // TODO Auto-generated method stub
    try {

         System.out.println(" 11111");


        SimpleJdbcCall simpleJdbcCall = new SimpleJdbcCall(dataSource);
        simpleJdbcCall.withCatalogName("NAMED_DRIVER_SAVE").withProcedureName("PR_NAMED_DRIVER_SAVE")
                .withoutProcedureColumnMetaDataAccess()
                .declareParameters(new SqlParameter("P_VCH_NAME", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_NEW_IC_NO", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_OLD_IC_NO", OracleTypes.VARCHAR),
                        new SqlParameter("P_VCH_GENDER", OracleTypes.VARCHAR),
                        new SqlParameter("P_VCH_RELATIONSHIP", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_AGE", OracleTypes.NUMBER),
                        new SqlParameter("P_VCH_DRIVER_EXPERIENCE", OracleTypes.VARCHAR));

        SqlParameterSource inputParams = new MapSqlParameterSource()
                .addValue("P_VCH_NAME", quotationDO.getNameddrivername())
                .addValue("P_NUM_NEW_IC_NO", quotationDO.getNamednewicno())
                .addValue("P_NUM_OLD_IC_NO", quotationDO.getNamedoldicno())
                .addValue("P_VCH_GENDER", quotationDO.getNamedgender())
                .addValue("P_VCH_RELATIONSHIP", quotationDO.getNameddriverrelationship())
                .addValue("P_NUM_AGE", quotationDO.getNamedage())
                .addValue("P_VCH_DRIVER_EXPERIENCE", quotationDO.getNameddriverexperience());

        Map<String, Object> transactionStatus = simpleJdbcCall.execute(inputParams);
        System.out.println( transactionStatus);

    } catch (Exception e) {
        System.out.println(e);
    }
}

我在过程中使用了return语句，但它不起作用

这是java代码

public void saveNamedDrivers(QuotationDO quotationDO) {
    // TODO Auto-generated method stub
    try {

         System.out.println(" 11111");


        SimpleJdbcCall simpleJdbcCall = new SimpleJdbcCall(dataSource);
        simpleJdbcCall.withCatalogName("NAMED_DRIVER_SAVE").withProcedureName("PR_NAMED_DRIVER_SAVE")
                .withoutProcedureColumnMetaDataAccess()
                .declareParameters(new SqlParameter("P_VCH_NAME", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_NEW_IC_NO", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_OLD_IC_NO", OracleTypes.VARCHAR),
                        new SqlParameter("P_VCH_GENDER", OracleTypes.VARCHAR),
                        new SqlParameter("P_VCH_RELATIONSHIP", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_AGE", OracleTypes.NUMBER),
                        new SqlParameter("P_VCH_DRIVER_EXPERIENCE", OracleTypes.VARCHAR));

        SqlParameterSource inputParams = new MapSqlParameterSource()
                .addValue("P_VCH_NAME", quotationDO.getNameddrivername())
                .addValue("P_NUM_NEW_IC_NO", quotationDO.getNamednewicno())
                .addValue("P_NUM_OLD_IC_NO", quotationDO.getNamedoldicno())
                .addValue("P_VCH_GENDER", quotationDO.getNamedgender())
                .addValue("P_VCH_RELATIONSHIP", quotationDO.getNameddriverrelationship())
                .addValue("P_NUM_AGE", quotationDO.getNamedage())
                .addValue("P_VCH_DRIVER_EXPERIENCE", quotationDO.getNameddriverexperience());

        Map<String, Object> transactionStatus = simpleJdbcCall.execute(inputParams);
        System.out.println( transactionStatus);

    } catch (Exception e) {
        System.out.println(e);
    }
}

[我使用

DBMS_output.put_line（p_NAMED_ID）；

在debbuging sql过程中获得了输出，但是如何在上面的java代码中获得它呢

public void saveNamedDrivers(QuotationDO quotationDO) {
    // TODO Auto-generated method stub
    try {

         System.out.println(" 11111");


        SimpleJdbcCall simpleJdbcCall = new SimpleJdbcCall(dataSource);
        simpleJdbcCall.withCatalogName("NAMED_DRIVER_SAVE").withProcedureName("PR_NAMED_DRIVER_SAVE")
                .withoutProcedureColumnMetaDataAccess()
                .declareParameters(new SqlParameter("P_VCH_NAME", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_NEW_IC_NO", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_OLD_IC_NO", OracleTypes.VARCHAR),
                        new SqlParameter("P_VCH_GENDER", OracleTypes.VARCHAR),
                        new SqlParameter("P_VCH_RELATIONSHIP", OracleTypes.VARCHAR),
                        new SqlParameter("P_NUM_AGE", OracleTypes.NUMBER),
                        new SqlParameter("P_VCH_DRIVER_EXPERIENCE", OracleTypes.VARCHAR));

        SqlParameterSource inputParams = new MapSqlParameterSource()
                .addValue("P_VCH_NAME", quotationDO.getNameddrivername())
                .addValue("P_NUM_NEW_IC_NO", quotationDO.getNamednewicno())
                .addValue("P_NUM_OLD_IC_NO", quotationDO.getNamedoldicno())
                .addValue("P_VCH_GENDER", quotationDO.getNamedgender())
                .addValue("P_VCH_RELATIONSHIP", quotationDO.getNameddriverrelationship())
                .addValue("P_NUM_AGE", quotationDO.getNamedage())
                .addValue("P_VCH_DRIVER_EXPERIENCE", quotationDO.getNameddriverexperience());

        Map<String, Object> transactionStatus = simpleJdbcCall.execute(inputParams);
        System.out.println( transactionStatus);

    } catch (Exception e) {
        System.out.println(e);
    }
}

映射字符串包含

过程不会返回它显示的任何警告

RETURN在过程中不起任何作用。您需要为要返回的内容指定一个OUT参数我收到了这个错误[错误]PLS-00372（59:4）：PLS-00372：在一个过程中，返回语句不能包含表达式否，不是返回语句，而是。是的，我已将其更改为

P_NUM_AGE In OUT NUMBER，

但是案例1：我需要返回

输入输出参数

案例2：我需要返回序列值1）PL/SQ中有两种“子程序”：“过程”和“函数”。根据定义，“过程”不会“返回*任何东西！”。这就是“函数”的作用。2）听起来这里的解决方案是使用OUT或IN-OUT参数。问：你尝试过吗？问：发生了什么事？请查看此处了解更多信息：
