java - 在 Java 中调用 Oracle Sproc 时出现问题(使用 Spring 3.0)

Question

在使用Spring 3.0的Java开发中， 我在执行为 Oracle 编写的存储过程时遇到问题。

这是存储过程代码:

create or replace PROCEDURE            
ADD_PRODUCT
( product_id IN VARCHAR2
, description IN VARCHAR2
, weight IN FLOAT
, specification IN VARCHAR2
, category IN VARCHAR2
, manufacturer IN VARCHAR2
, syncount IN NUMBER
, nonAccentedURL IN VARCHAR2
, nonAccentedManufacturer IN VARCHAR2
) AS
    recCount number;
BEGIN
      recCount := 0;

      SELECT    COUNT(*) 
      INTO  recCount
      FROM  ERP_MANUFACTURER
      WHERE NAME = manufacturer;  



  IF recCount < 1 THEN
    INSERT INTO ERP_MANUFACTURER (NAME, URL) VALUES (manufacturer,     nonAccentedManufacturer);
  END IF;

  INSERT INTO ERP_PRODUCT (ID, DESCRIPTION, WEIGHT, SPECIFICATION, CATEGORY, MANUFACTURER, SYNCCOUNT, URL) 
  VALUES     (product_id,description,weight,specification,category,manufacturer,syncount,nonAccentedURL);        

END ADD_PRODUCT；

这是代码(在 DAO 中):

public int ADD_Product(String codigo_produto, String descricao, float peso, String espeficiacao, String categoria, String fabricante, int sysCount, int SENT_STATUS) throws Exception {

    SimpleJdbcCall caller = new SimpleJdbcCall(this.jdbcTemplate).withFunctionName("ADD_PRODUCT");

    MapSqlParameterSource paramMap = new MapSqlParameterSource();

    paramMap.addValue("product_id", codigo_produto, Types.VARCHAR);
    paramMap.addValue("description", descricao, Types.VARCHAR);
    paramMap.addValue("weight", peso, Types.FLOAT);
    paramMap.addValue("specification",espeficiacao, Types.VARCHAR);
    paramMap.addValue("category", categoria, Types.VARCHAR);
    paramMap.addValue("manufacturer", fabricante, Types.VARCHAR);
    paramMap.addValue("syncount", sysCount, Types.NUMERIC);
    paramMap.addValue("nonAccentedURL", URLEncoder.encode(deAccent(espeficiacao).toLowerCase(), "UTF-8"), Types.VARCHAR);
    paramMap.addValue("nonAccentedManufacturer", URLEncoder.encode(deAccent(fabricante).toLowerCase(), "UTF-8"), Types.VARCHAR);

    Map<String, Object> i = caller.execute(paramMap);

    return i.size();
}

当该方法执行时， 以下是错误日志:

谁能帮我调试这个。

谢谢。

Answer 1

您正在使用存储过程，因此使用withProcedureName代替withFunctionName，如下所示:

SimpleJdbcCall caller = 
          new SimpleJdbcCall(this.jdbcTemplate).withProcedureName("ADD_PRODUCT");

withFunctionName 期望返回类型与 DB function 应该具有的类型相同。
