小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

StoredProcedure是一個(gè)抽象類，必須寫一個(gè)子類來繼承它，這個(gè)類是用來簡化JDBCTemplate執(zhí)行存儲(chǔ)過程操作的。
首先我們寫一個(gè)實(shí)現(xiàn)類：
[java] view plaincopyprint?

template.setIntegerParam("@parama");寫在前面然后再寫template.setReturnParam("rows", new FirstReportRowMapper());的話，就會(huì)報(bào)空指針錯(cuò)誤。
這個(gè)“rows”可以隨便取名字，不過下面map.get("rows")要和你取的名字一致，因?yàn)镾toredProcedureTemplate會(huì)將結(jié)果集以這個(gè)名字保存在map中返回。
還有要注意的就是設(shè)置sqlparamter的順序要和存儲(chǔ)過程中參數(shù)的順序要一致，不然也會(huì)報(bào)錯(cuò).

[java語言]spring對(duì)oracle的clob和StoredProcedure 的處理
邢紅瑞 發(fā)表于 2005-4-21 9:16:20
使用spring后發(fā)現(xiàn)和oracle的驅(qū)動(dòng)有了不解之緣，最初是spring的jdbc存取oracle的clob字段，出現(xiàn)
org.springframework.transaction.TransactionSystemException: Could not roll back JDBC transaction; nested exception is java.sql.SQLException: Io 異常: Software caused connection abort: socket write error
問了Juergen Hoeller幾次，也沒有知道原因所在。只有加入了hibernate解決此問題，hibernate如何解決oracle的clob字段，看我以前的帖子（http://blogger.org.cn/blog/more.asp?name=hongrui&id=1171）。
后來看到agilejava也遇到這類問題，原來是ojdbc14.jar驅(qū)動(dòng)的問題，改為9.2.0.5.0，一切OK了。相關(guān)blog（http://agilejava.blogbus.com/logs/2005/02/1031034.html）
因?yàn)楝F(xiàn)在大量用到存儲(chǔ)過程，打算使用spring的StoredProcedure 進(jìn)行操作，發(fā)現(xiàn)運(yùn)行到SQLErrorCodes loaded: [DB2, HSQL, MS-SQL, MySQL, Oracle, Informix, PostgreSQL, Sybase] 就停了，沒有辦法，問了Thomas Risberg，他說程序沒有錯(cuò)誤，我當(dāng)時(shí)就暈了，后來聽說虎子做過類似的工作，代碼給虎子看，也說沒錯(cuò)，而且在它那里運(yùn)行正常，我生氣了。聽從他的建議，加入spring源碼調(diào)試，也不知道問題所在。認(rèn)為是數(shù)據(jù)庫的問題，換了臺(tái)數(shù)據(jù)庫還是不行。最后把防火墻撤掉，讓虎子直接訪問數(shù)據(jù)庫，他那里一切正常。問題明朗了，數(shù)據(jù)庫一樣的，代碼一樣的，唯一不同的是jdk和oracle驅(qū)動(dòng)，他的jdk1.425，我得1.421，差別不大，那就是驅(qū)動(dòng)的問題，我換了以前用的ojdbc14.jar，現(xiàn)在用的版本10.1.0.2.0，換到9.0.2.0.0，一切OK，此時(shí)，我已經(jīng)出離憤怒了，建議oracle驅(qū)動(dòng)最好是自己命名，把文件名加上版本信息，要不會(huì)死人的。
下面是我作測試的PLSQL代碼
CREATE OR REPLACE package chapter_13 as
end;
PROCEDURE founder(oFields out rs) IS
package springtest;
import java.sql.*;
import javax.sql.*;
public class TestDao {
??? public void execute() throws Exception {
??????? DemoStoredProcedure proc = new DemoStoredProcedure(ds);
??????? proc.execute(params);
??? }
??? private class DemoStoredProcedure extends StoredProcedure {
??????????? declareParameter(
??????????????????? return rs.getString(1);
??????????? compile();
?
總結(jié)
