1.               建立对象.由于要操作的都是对象或者对象组成的列表,所以需要在java代码中和oracle中定义相对应的对象.这里以STBid集合为例,首先是数据库端定义字符串(stbid)对象

CREATE OR REPLACE TYPE TYPE_STB_ID AS OBJECT

(

  STBID VARCHAR2(64)

)

                再定义字符串(stbid)集合

                     CREATE OR REPLACE TYPE STB_ID_CONNECTIONS

AS TABLE OF TYPE_STB_ID

                接下来在java中定义与字符串对象对应的对象:

import java.sql.Connection;

import java.sql.SQLException;

import oracle.jdbc.OracleTypes;

import oracle.jpub.runtime.MutableStruct;

import oracle.sql.Datum;

import oracle.sql.ORAData;

import oracle.sql.ORADataFactory;

import oracle.sql.STRUCT;

 

public class StbUpdate implements ORAData, ORADataFactory

{

   

    public static final String _SQL_NAME = "TYPE_STB_ID";

   

    private String stbId = "";// NOPMD

   

    public String getStbId()

    {

        return stbId;

    }

   

    public void setStbId(String stbId)

    {

        this.stbId = stbId;

        try

        {

            _struct.setAttribute(0, this.stbId);

        }

        catch (final SQLException e)

        {

           

        }

    }

   

    /**

     * toString

     *

     * @return String

     */

    @Override

    public String toString()

    {

        return this.stbId;

    }

   

    public static final int _SQL_TYPECODE = OracleTypes.STRUCT;

   

    protected MutableStruct _struct;

   

    static int[] _sqlType = {OracleTypes.VARCHAR};

   

    static ORADataFactory[] _factory = new ORADataFactory[1];

   

    static StbUpdate _stbUpdate=new StbUpdate();

   

    public StbUpdate(String stbid)

    {

        _struct = new MutableStruct(new Object[1], _sqlType, _factory);

        this.stbId = stbid;

        try

        {

            _struct.setAttribute(0, this.stbId);

        }

        catch (final SQLException e)

        {

           

        }

    }

   

    public Datum toDatum(final Connection conn)

        throws SQLException

    {

        if (null == _struct)

        {

            _struct = new MutableStruct(new Object[1], _sqlType, _factory);

            try

            {

                _struct.setAttribute(0, this.stbId);

            }

            catch (final SQLException e)

            {

               

            }

        }

        final Datum d = _struct.toDatum(conn, _SQL_NAME);

        return d;

    }

   

    public ORAData create(final Datum d, final int sqlType)

        throws SQLException

    {

        return create(null, d, sqlType);

    }

   

    protected ORAData create(StbUpdate o, final Datum d, final int sqlType)

        throws SQLException

    {

        if (d == null)

        {

            return null;

        }

        if (o == null)

        {

            o = new StbUpdate();

        }

        o._struct = new MutableStruct((STRUCT)d, _sqlType, _factory);

        return o;

    }

   

    public static ORADataFactory getORADataFactory()

    {

        return _stbUpdate;

    }

   

}

这里需要引进两个oracle的包,一个是ojdbc.jar(MQMC用的是dbchecker.jar),上面所引的oracle下的类全都是来自这个包,还有一个是charsets.jar,这个是oracle的多语言包,用来解决varchar类型字段编码乱码问题的.

              至于Java代码中与字符串集合对应的对象,要在调用存储过程的方法中设置.

2.               Oracle中的存储过程,总体思路就是先将获得的stbid集合放入一张临时表中,再根据关联关系将数据查询出来存放进另一个集合中,最后将该集合返回.

CREATE OR REPLACE PROCEDURE PRC_QUERY_STB_INFOS

(

   STBIDS IN STB_ID_CONNECTIONS,

   STBINFOS OUT STB_INFO_CONNECTIONS

)

IS

   V_TOTALCOUNT number(10);

   TSTBIDS          const.varchararraytyp;

   MSTATES          const.numarraytyp;

   MSRIGHTS         const.numarraytyp;

   MPRECISIONSTATES const.numarraytyp;

   MLEVELS          const.numarraytyp;

   ASTATES          const.numarraytyp;

   AISRIGHTS        const.numarraytyp;

   ALEVELS          const.numarraytyp;

   SSTATES          const.numarraytyp;

   SASTATES         const.numarraytyp;

   SLEVELS          const.numarraytyp;

   v_sql            VARCHAR2(4096);

BEGIN

     v_sql        := 'insert into T_STB_ID_TMP(stbid) values (:1)';

     V_TOTALCOUNT := STBIDS.COUNT;

     STBINFOS     := STB_INFO_CONNECTIONS();

 

     FOR i IN 1 .. V_TOTALCOUNT LOOP

        EXECUTE IMMEDIATE v_sql

          using STBIDS(i).STBID;

     END LOOP ;

 

     v_sql := 'SELECT t.stbid, t.manualstate,t.manualisright,t.manualprecisionstate,t.manuallevel,t.autostate,

       t.autoisright,t.autolevel,t.signalstate,t.samplestate,t.samplelevel from T_STB_ID_TMP s,T_TASK_STB t

       where t.stbid=s.stbid';

 

     EXECUTE IMMEDIATE v_sql BULK COLLECT

             INTO TSTBIDS, MSTATES, MSRIGHTS, MPRECISIONSTATES, MLEVELS, ASTATES, AISRIGHTS, ALEVELS, SSTATES, SASTATES, SLEVELS;

     FOR i IN 1..TSTBIDS.COUNT LOOP

           STBINFOS.extend;

           STBINFOS(STBINFOS.count) := TYPE_STB_INFO(TSTBIDS(i),MSTATES(i),MSRIGHTS(i),MPRECISIONSTATES(i),

                                      MLEVELS(i),ASTATES(i),AISRIGHTS(i),ALEVELS(i),SSTATES(i),SASTATES(i),SLEVELS(i));

     END LOOP ;

 

     COMMIT;

EXCEPTION

     WHEN OTHERS THEN

          STBINFOS:=STB_INFO_CONNECTIONS();

END PRC_QUERY_STB_INFOS;

 

3.               java代码调用存储过程并获得查询结果.这里分两种情况说明.

a.       JDBC调用,代码如下:

 

public static void callprocedure()

    {

        Connection conn = null;

        PreparedStatement ps = null;

        CallableStatement callableStatement = null;

        ResultSet rs = null;

        try

        {

            // 获取数据库连接

            conn = DriverManager.getConnection("jdbc:oracle:thin:@10.40.70.10:1521:orcl", "sqmlwx", "sqmlwx");

            if (null == conn)

            {

                System.out.println("get conn is null");

                return;

            }

            else

            {

                System.out.println("get conn not null");

            }

            // 预调用存储过程

            callableStatement = conn.prepareCall("{ call PRC_QUERY_STB_INFOS(?,?)}");

           

            // 构造传入参数

            List lstStb=new ArrayList();

            for (int i = 1; i <= 700; i++)

            {

                lstStb.add("stb_ptest_" + i);

            }

            StbUpdate[] strArray=new StbUpdate[700];

            for (int i = 0; i < strArray.length; i++)

            {

                strArray[i] = new StbUpdate(lstStb.get(i));

            }

           

            // stbid集合对象

            ArrayDescriptor desc = ArrayDescriptor.createDescriptor("STB_ID_CONNECTIONS",

                conn);

            // 构造ARRAY

            ARRAY  parameter = new ARRAY(desc, conn, strArray);

            // 设置传入参数

            callableStatement.setArray(1, parameter);

            // 设置返回结果

            callableStatement.registerOutParameter(2, Types.ARRAY, "STB_INFO_CONNECTIONS");        

           

            // 获取操作结果

            Array array = (Array)callableStatement.getObject(2);

            // 为空校验

            if (null == array)

            {

                System.out.println(" array is null");

            }

            // 不为空则打印获得结果

            else

            {

                System.out.println(" array is not null");

                Object obj;

                String ss="";

                //获取存储过程返回的结果集

                final Object[] reasonValueList = (Object[])array.getArray();

                //判断返回的结果集是否为空,如果不为空则输出结果集记录条数

                System.out.println(reasonValueList==null ? "null " : " not null: "+reasonValueList.length);

                for (final Object reasonValueResult : reasonValueList)

                {

                    final Struct s = (Struct)reasonValueResult;

                    obj=s.getAttributes()[0];

                    ss=obj.toString();

                    System.out.println("=======================================: "+ss+" : "+s.getAttributes()[1]);

                }

            }  

        }

        catch (SQLException e)

        {

            e.printStackTrace();

        }

        catch (Exception e)

        {

            e.printStackTrace();

        }

        finally

        {

            try

            {

                if (null != rs)

                {

                    rs.close();

                }

                if (ps != null)

                {

                    ps.close();

                }

                if (null != conn)

                {

                    conn.close();

                }

            }

            catch (SQLException e)

            {

                e.printStackTrace();

            }

        }

}

采用这种方式获得的集合reasonValueList里面存放的是stb对象的属性集合,需要自己将其再封装成对应的对象(Stb).

b.       IBATIS调用,首先要配置sql文件

 

<parameterMap id="queryStbTaskidMap" class="java.util.HashMap">

        <parameter property="idList" jdbcType="STB_ID_CONNECTIONS"

            javaType="java.util.ArrayList" mode="IN"  

            typeHandler="com.netom.common.device.StbInfoHandler" /> 

        <parameter property="result" jdbcType="ARRAY" javaType="java.sql.Array"

            typeName="STB_INFO_CONNECTIONS" mode="OUT"

            typeHandler="com.netom.common.device.StbInfoHandler" />

    parameterMap>

    <procedure id="queryStbTaskidListInfo" parameterMap="queryStbTaskidMap">

        { call PRC_QUERY_STB_INFOS(?, ?) }

procedure>

先是参数映射关系parameterMap,其中包含两个参数,一个为传入参数,另一个为结果参数,都为集合,最后一个是定义存储过程procedure.

其次,需要多写一个对象处理类(即配置文件中的StbInfoHandler),里面主要是两个方法:第一个是传入参数重新编码的方法,另一个是获得集合后封装对象的方法.

import java.math.BigDecimal;

import java.sql.Array;

import java.sql.SQLException;

    private static final String EMP_SALARY_REC ="TYPE_STB_ID";

    private static final String EMP_SALARY_TAB = "STB_ID_CONNECTIONS";

    static

    {

        JdbcTypeRegistry.setType(EMP_SALARY_REC, OracleTypes.STRUCT);

        JdbcTypeRegistry.setType(EMP_SALARY_TAB, OracleTypes.ARRAY);

    };

   

    /**

     */

    @Override

    public Object getResult(ResultGetter getter) throws SQLException

    {

        final List result = new ArrayList();

        Stb stbInfo = null;

        try

        {

           

            final Array array = (Array)getter.getObject();

            final Object[] reasonValueList = (Object[])array.getArray();

            for (final Object reasonValueResult : reasonValueList)

            {

                final Struct s = (Struct)reasonValueResult;

               

                try

                {

                    final int two = 2;

                    final int three = 3;

                    final int four = 4;

                    final int five = 5;

                    final int six = 6;

                    final int seven = 7;

                    final int eight = 8;

                    final int nine = 9;

                    final int ten = 10;

                    stbInfo = new Stb();

                    stbInfo.setStbID((String)s.getAttributes()[0]);

                    stbInfo.setManualState(((BigDecimal)s.getAttributes()[1]).intValue());

                    stbInfo.setManualIsRight(((BigDecimal)s.getAttributes()[two]).intValue());

                    stbInfo.setManualPrecisionState(((BigDecimal)s.getAttributes()[three]).intValue());

                    stbInfo.setManualLevel(((BigDecimal)s.getAttributes()[four]).intValue());

                    stbInfo.setAutoState(((BigDecimal)s.getAttributes()[five]).intValue());

                    stbInfo.setAutoIsRight(((BigDecimal)s.getAttributes()[six]).intValue());

                    stbInfo.setAutoLevel(((BigDecimal)s.getAttributes()[seven]).intValue());

                    stbInfo.setSignalState(((BigDecimal)s.getAttributes()[eight]).intValue());

                    stbInfo.setSampleState(((BigDecimal)s.getAttributes()[nine]).intValue());

                    stbInfo.setSampleLevel(((BigDecimal)s.getAttributes()[ten]).intValue());

                   

                    result.add(stbInfo);

                }

                catch (final Exception e)

                {

                    // 可能由于底层数据不合格,导致空指针异常

                    // 避免一条记录失败引起全部记录失败

                    Logger.error("Reason Error:" + stbInfo);

                }

            }

           

        }

        catch (final Exception e)

        {

            Logger.error("VMOSLevelHandler Error:" + e.getMessage());

        }

        return result;

    }

 

    /**

     * 设置参数

     *

     * @param ps 设置

     * @param param 参数

     * @throws SQLException 异常

     */

    @SuppressWarnings("unchecked")

    public void setParameter(final ParameterSetter setter, Object parameter)

        throws SQLException

    {

        if (parameter instanceof ArrayList)

        {

            final List arr = (ArrayList)parameter;

            StbUpdate[] strArray=new StbUpdate[arr.size()];

            for (int i = 0; i < strArray.length; i++)

            {

                strArray[i] = arr.get(i);

            }

            final Statement stmt = setter.getPreparedStatement();

            final org.apache.commons.dbcp.PoolableConnection conn = (org.apache.commons.dbcp.PoolableConnection)stmt.getConnection();

            final java.sql.Connection realConn = conn.getDelegate();

            final ArrayDescriptor desc = ArrayDescriptor.createDescriptor(EMP_SALARY_TAB,

                    realConn);

            parameter = new ARRAY(desc, realConn, strArray);

        }

        setter.setObject(parameter);

       

    }

 

    @Override

    public Object valueOf(String arg0)

    {

        // TODO Auto-generated method stub

        return null;

    }

}

 

最后,调用存储过程的方法中的代码

 

// 获取stbid队列

            for (final StbTaskBean stbTaskBean : lstUpdate)

            {

                tmpStbID = stbTaskBean.getStbRegisterReq().getStbId();

                idList.add(new StbUpdate(tmpStbID));

                reqMap.put(tmpStbID,

                    stbTaskBean.getStbRegisterReq());

            }

            final Map<String, Object> conditions = new HashMap<String, Object>();

            conditions.put("idList", idList);

            // 查询stb信息

            final Map result = dbHelper.dynamicQueryMap("Device.queryStbTaskidListInfo",

                conditions);

            if (!result.isEmpty())

            {

                stbList = (List) result.get(IndexConstants.KEY_RESULT);

               

                if (null != stbList)

                {

                    ……

                }

            }

1.               建立对象.由于要操作的都是对象或者对象组成的列表,所以需要在java代码中和oracle中定义相对应的对象.这里以STBid集合为例,首先是数据库端定义字符串(stbid)对象

CREATE OR REPLACE TYPE TYPE_STB_ID AS OBJECT

(

  STBID VARCHAR2(64)

)

                再定义字符串(stbid)集合

                     CREATE OR REPLACE TYPE STB_ID_CONNECTIONS

AS TABLE OF TYPE_STB_ID

                接下来在java中定义与字符串对象对应的对象:

import java.sql.Connection;

import java.sql.SQLException;

import oracle.jdbc.OracleTypes;

import oracle.jpub.runtime.MutableStruct;

import oracle.sql.Datum;

import oracle.sql.ORAData;

    public String getStbId()

    {

        return stbId;

    }

   

    public void setStbId(String stbId)

    {

        this.stbId = stbId;

        try

        {

            _struct.setAttribute(0, this.stbId);

        }

        catch (final SQLException e)

        {

           

        }

    }

   

    /**

     * toString

     *

     * @return String

     */

    @Override

    public String toString()

    {

        return this.stbId;

    }

   

    public static final int _SQL_TYPECODE = OracleTypes.STRUCT;

   

    protected MutableStruct _struct;

   

    static int[] _sqlType = {OracleTypes.VARCHAR};

   

    static ORADataFactory[] _factory = new ORADataFactory[1];

   

    static StbUpdate _stbUpdate=new StbUpdate();

   

    public StbUpdate(String stbid)

    {

        _struct = new MutableStruct(new Object[1], _sqlType, _factory);

        this.stbId = stbid;

        try

        {

            _struct.setAttribute(0, this.stbId);

        }

        catch (final SQLException e)

        {

           

        }

    }

   

    public Datum toDatum(final Connection conn)

        throws SQLException

    {

        if (null == _struct)

        {

            _struct = new MutableStruct(new Object[1], _sqlType, _factory);

            try

            {

                _struct.setAttribute(0, this.stbId);

            }

            catch (final SQLException e)

            {

               

            }

        }

        final Datum d = _struct.toDatum(conn, _SQL_NAME);

        return d;

    }

   

    public ORAData create(final Datum d, final int sqlType)

        throws SQLException

    {

        return create(null, d, sqlType);

    }

   

    protected ORAData create(StbUpdate o, final Datum d, final int sqlType)

        throws SQLException

    {

        if (d == null)

        {

            return null;

        }

        if (o == null)

        {

            o = new StbUpdate();

        }

        o._struct = new MutableStruct((STRUCT)d, _sqlType, _factory);

        return o;

    }

   

    public static ORADataFactory getORADataFactory()

    {

        return _stbUpdate;

    }

   

}

这里需要引进两个oracle的包,一个是ojdbc.jar(MQMC用的是dbchecker.jar),上面所引的oracle下的类全都是来自这个包,还有一个是charsets.jar,这个是oracle的多语言包,用来解决varchar类型字段编码乱码问题的.

采用这种方式获得的集合reasonValueList里面存放的是stb对象的属性集合,需要自己将其再封装成对应的对象(Stb).

b.       IBATIS调用,首先要配置sql文件

 

<parameterMap id="queryStbTaskidMap" class="java.util.HashMap">

        <parameter property="idList" jdbcType="STB_ID_CONNECTIONS"

            javaType="java.util.ArrayList" mode="IN"  

            typeHandler="com.netom.common.device.StbInfoHandler" /> 

        <parameter property="result" jdbcType="ARRAY" javaType="java.sql.Array"

            typeName="STB_INFO_CONNECTIONS" mode="OUT"

            typeHandler="com.netom.common.device.StbInfoHandler" />

    parameterMap>

    <procedure id="queryStbTaskidListInfo" parameterMap="queryStbTaskidMap">

        { call PRC_QUERY_STB_INFOS(?, ?) }

procedure>

先是参数映射关系parameterMap,其中包含两个参数,一个为传入参数,另一个为结果参数,都为集合,最后一个是定义存储过程procedure.

其次,需要多写一个对象处理类(即配置文件中的StbInfoHandler),里面主要是两个方法:第一个是传入参数重新编码的方法,另一个是获得集合后封装对象的方法.

最后,调用存储过程的方法中的代码

 

// 获取stbid队列

            for (final StbTaskBean stbTaskBean : lstUpdate)

            {

                tmpStbID = stbTaskBean.getStbRegisterReq().getStbId();

                idList.add(new StbUpdate(tmpStbID));

                reqMap.put(tmpStbID,

                    stbTaskBean.getStbRegisterReq());

            }

            final Map<String, Object> conditions = new HashMap<String, Object>();

            conditions.put("idList", idList);

            // 查询stb信息

            final Map result = dbHelper.dynamicQueryMap("Device.queryStbTaskidListInfo",

                conditions);

            if (!result.isEmpty())

            {

                stbList = (List) result.get(IndexConstants.KEY_RESULT);

               

                if (null != stbList)

                {

                    ……

                }

            }
