Oracle自定义类型及存储过程如下：

CREATE OR REPLACE TYPE ARR_OBJECT AS OBJECT(

TRADENO VARCHAR2(32),

DEAL_TYPE VARCHAR2(2),

TURNOVER VARCHAR2(20)

);

CREATE OR REPLACE TYPE WEALTH_DEAL_DETAIL_ARRAY IS TABLE OF ARR_OBJECT;

PROCEDURE pro_wealth_deal_detail_array(P_FUND_ACCNO IN VARCHAR2,

P_OPEN_DEALNO IN VARCHAR2,

P_HOLD_ACCNO IN VARCHAR2,

P_MARKET_NO IN VARCHAR2,

P_SECURNO IN VARCHAR2,

P_TRADE_DATE IN DATE,

P_ARR OUT WEALTH_DEAL_DETAIL_ARRAY)

CURSOR CUR_WEALTH_DEAL_DETAIL IS

SELECT TRADENO,DEAL_TYPE,TURNOVER FROM WEALTH_DEAL_DETAIL T

WHERE T.FUND_ACCNO LIKE P_FUND_ACCNO

AND T.OPEN_DEALNO LIKE P_OPEN_DEALNO

AND T.HOLD_ACCNO LIKE P_HOLD_ACCNO

AND T.MARKETNO LIKE P_MARKET_NO

AND T.SECURNO LIKE P_SECURNO

AND T.TRADE_DATE <= TRUNC(P_TRADE_DATE) + 1

AND T.TRADE_DATE >= TRUNC(P_TRADE_DATE)

ORDER BY TRADENO ASC;

V_WEALTH_DEAL_DETAIL CUR_WEALTH_DEAL_DETAIL%ROWTYPE;

V_IDX INT := 0;

BEGIN

P_ARR := WEALTH_DEAL_DETAIL_ARRAY();

OPEN CUR_WEALTH_DEAL_DETAIL;

LOOP

FETCH CUR_WEALTH_DEAL_DETAIL INTO V_WEALTH_DEAL_DETAIL;

EXIT WHEN CUR_WEALTH_DEAL_DETAIL%NOTFOUND;

P_ARR.EXTEND;

P_ARR(V_IDX) := ARR_OBJECT(V_WEALTH_DEAL_DETAIL.TRADENO,V_WEALTH_DEAL_DETAIL.DEAL_TYPE,V_WEALTH_DEAL_DETAIL.TURNOVER);

V_IDX := V_IDX + 1;

END LOOP;

CLOSE CUR_WEALTH_DEAL_DETAIL;

END pro_wealth_deal_detail_array;

5.DaoSupport.java:

package com.ibatis.customtype;

import java.io.IOException;

import java.io.Reader;

import org.apache.log4j.Logger;

public SqlMapClient getSqlMapClient() {

return sqlMapClient;

}

public DaoSupport() {

Reader reader;

try {

reader = Resources.getResourceAsReader("com/ibatis/customtype/sqlmap-config.xml");

sqlMapClient = SqlMapClientBuilder.buildSqlMapClient(reader);

} catch (IOException e) {

logger.error("读取Ibatis配置文件出错！");

logger.error(e);

}

6.WealthDealDetailDto.java:

package com.ibatis.customtype;

public class WealthDealDetailDto {

@Override

public String toString() {

return tradeno + "\t" + dealType + "\t" + turnover;

}

private String tradeno;

private String dealType;

private String turnover;

public String getTradeno() {

public void setTurnover(String turnover) {

7.ArrayTypeHandler.java:

package com.ibatis.customtype;

import java.sql.CallableStatement;

import java.sql.PreparedStatement;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.util.ArrayList;

import java.util.List;

import oracle.jdbc.OracleTypes;

import oracle.sql.Datum;

import oracle.sql.STRUCT;

import com.ibatis.sqlmap.engine.type.TypeHandler;

public class ArrayTypeHandler implements TypeHandler {

public boolean equals(Object arg0, String arg1) {

return null;

}

public Object getResult(CallableStatement cs, int arg1)

throws SQLException {

List<WealthDealDetailDto> dtos = new ArrayList<WealthDealDetailDto>();

ResultSet rs = cs.getArray(arg1).getResultSet();

while (rs.next()) {

Datum[] data = ((STRUCT)rs.getObject(2)).getOracleAttributes();

WealthDealDetailDto dto = new WealthDealDetailDto();

if (data[0] != null) {

dto.setTradeno(new String(data[0].getBytes()));

8.ArrayTypeDao.java:

package com.ibatis.customtype;

import java.sql.SQLException;

import java.util.List;

import java.util.Map;

import org.apache.log4j.Logger;

public class ArrayTypeDao extends DaoSupport {

private Logger logger = Logger.getLogger(ArrayTypeDao.class);

@SuppressWarnings("unchecked")

public List<WealthDealDetailDto> getWealthDealDetailList(Map<Object, Object> paramtersMap)

{

try {

getSqlMapClient().queryForList("get-wealth-deal-detail-array", paramtersMap);

List<WealthDealDetailDto> dtos = (List<WealthDealDetailDto>) paramtersMap.get("result");

return dtos;

} catch (SQLException e) {

logger.error("调用存储过程出错！");

logger.error(e);

}

return null;

}

9.测试类Test.java:

package com.ibatis.customtype;

import java.util.Calendar;

import java.util.Date;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import org.apache.log4j.Logger;

public class Test {

private static Logger logger = Logger.getLogger(Test.class);

/**

* @param args

public static void main(String[] args) {

ArrayTypeDao atd = new ArrayTypeDao();

Map<Object, Object> paramtersMap = new HashMap<Object, Object>();

paramtersMap.put("fundAccno","%");

paramtersMap.put("openDealno","%");

paramtersMap.put("holdAccno","%");

paramtersMap.put("marketno","%");

paramtersMap.put("securno","%");

Calendar c = Calendar.getInstance();

c.set(Calendar.YEAR, 2010);

c.set(Calendar.MONTH,11);

c.set(Calendar.DATE, 24);

Date date = c.getTime();

paramtersMap.put("tradeDate",date);

List<WealthDealDetailDto> dtos = atd.getWealthDealDetailList(paramtersMap);

logger.info("调用存储过程返回数据：" + dtos.size());

if (dtos != null && dtos.size() > 0) {

logger.info("Tradeno\tDeal_type\tTurnover");

for (int i=0;i<dtos.size();i++) {

WealthDealDetailDto dto = dtos.get(i);

logger.info(dto);

}

说明：首先，我自定义了一个Object ARR_OBJECT.然后定义了一个类型WEALTH_DEAL_DETAIL_ARRAY，指明是ARR_OBJECT类型。这样就相当于Java中的List<Object>。在存储过程中使用WEALTH_DEAL_DETAIL_ARRAY作为OUT类型参数，根据传入的5个IN类型参数从WEALTH_DEAL_DETAIL表查询符合条件的数据，并放入WEALTH_DEAL_DETAIL_ARRAY中。在Java中，在Ibatis的配置文件中OUT类型参数jdbcType需指定为ARRAY，并且需要指定类型的名字，以及处理该类型的Handler。那么在Handler中呢，因为我们最终需要的是List<WealthDealDetailDto>类型，那么就需要自己从结果集中组装数据，封装成此类型。最后从传入的参数Map中获取sqlmap中配置的property，即得到此OUT参数的结果。
