Spring的SimpleJdbcTemplate将存储过程的调用进行了良好的封装，但可惜只能用于jdk1.5的环境，无法再jdk1.4环境下使用，而JdbcTemplate则完全适用于jdk1.4下的环境，下面列出使用JdbcTemplate调用Oracle存储过程的一些方法：

一) 无返回值的存储过程调用
存储过程：??
CREATE OR REPLACE PROCEDURE TESTPRO(PARAM1 IN VARCHAR2,PARAM2 IN VARCHAR2) AS
BEGIN
??? INSERT INTO TESTTABLE (ID,NAME) VALUES (PARAM1, PARAM2);
END TESTPRO;


Java代码：???
package com.dragon.test;
import org.springframework.jdbc.core.JdbcTemplate;
public class JdbcTemplateTest {
? private JdbcTemplate jdbcTemplate;
? public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
? this.jdbcTemplate = jdbcTemplate;
? }
? public void test(){
???? this.jdbcTemplate.execute("call testpro('p1','p2')");
? }
}
注:存储过程TESTPRO中用到了表TESTTABLE(ID, NAME),需事先建好.


二)有返回值的存储过程（非结果集）???
存储过程：???
CREATE OR REPLACE PROCEDURE TESTPRO(PARAM1 IN VARCHAR2,PARAM2 OUT VARCHAR2) AS??
BEGIN???
??? SELECT INTO PARAM2 FROM TESTTABLE WHERE ID= PARAM1;???
END TESTPRO;


Java代码：
public void test() {
? String param2Value = (String) jdbcTemplate.execute(
???? new CallableStatementCreator() {
??????? public CallableStatement createCallableStatement(Connection con) throws SQLException {
?????????? String storedProc = "{call testpro(?,?)}";// 调用的sql
?????????? CallableStatement cs = con.prepareCall(storedProc);
?????????? cs.setString(1, "p1");// 设置输入参数的值
?????????? cs.registerOutParameter(2, OracleTypes.VARCHAR);// 注册输出参数的类型
?????????? return cs;
??????? }
???? }, new CallableStatementCallback() {
???????? public Object doInCallableStatement(CallableStatement cs) throws SQLException, DataAccessException {
?????????? cs.execute();
?????????? return cs.getString(2);// 获取输出参数的值
???? }
? });
}
注：cs.getString(2)中的数值2是存储过程中的out列对应的索引值(第一个参数索引为1,如此类推)


三)有返回值的存储过程（结果集）????
因oracle存储过程所有返回值都是通过out参数返回的,列表同样也不例外,但由于是集合,所以不能用一般的参数,必须要用pagkage,分两部分:??
1.建一个程序包,如下：
CREATE OR REPLACE PACKAGE TESTPACKAGE AS
? TYPE TEST_CURSOR IS REF CURSOR;
END TESTPACKAGE;
2.建立存储过程,如下：
CREATE OR REPLACE PROCEDURE TESTPRO(PARAM1 IN VARCHAR2,test_cursor out TESTPACKAGE.TEST_CURSOR) IS
BEGIN
???? OPEN test_cursor FOR SELECT * FROM TESTTABLE;
END TESTPRO;
可以看到，列表是通过把游标作为一个out参数来返回的。??


Java代码：
public void test() {
? List resultList = (List) jdbcTemplate.execute(
???? new CallableStatementCreator() {
??????? public CallableStatement createCallableStatement(Connection con) throws SQLException {
?????????? String storedProc = "{call testpro(?,?)}";// 调用的sql
?????????? CallableStatement cs = con.prepareCall(storedProc);
?????????? cs.setString(1, "p1");// 设置输入参数的值
?????????? cs.registerOutParameter(2, OracleTypes.CURSOR);// 注册输出参数的类型
?????????? return cs;
??????? }
???? }, new CallableStatementCallback() {
??????? public Object doInCallableStatement(CallableStatement cs) throws SQLException,DataAccessException {
?????????? List resultsMap = new ArrayList();
?????????? cs.execute();
?????????? ResultSet rs = (ResultSet) cs.getObject(2);// 获取游标一行的值
?????????? while (rs.next()) {// 转换每行的返回值到Map中
????????????? Map rowMap = new HashMap();
????????????? rowMap.put("id", rs.getString("id"));
????????????? rowMap.put("name", rs.getString("name"));
????????????? resultsMap.add(rowMap);
?????????? }
?????????? rs.close();
?????????? return resultsMap;
??????? }
? });
? for (int i = 0; i < resultList.size(); i++) {
???? Map rowMap = (Map) resultList.get(i);
???? String id = rowMap.get("id").toString();
???? String name = rowMap.get("name").toString();
???? System.out.println("id=" + id + ";name=" + name);
? }
}
