Ibatis调用存储过程

Ibatis 2009-10-11 15:31 阅读7 评论0 字号：大中小

procedure.xml的ibatis配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="PROCEDURE">

<parameterMap class="map" id="proPermissionDevicePerson">
   <parameter property="deviceId" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/>
   <parameter property="deviceType" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/>
   <parameter property="permissionType" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/>
   <parameter property="userId" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/>
   <parameter property="result" jdbcType="VARCHAR" javaType="java.lang.String" mode="OUT"/>
</parameterMap>

JAVA调用实现PermissionDAOIbatisImpl.java如下：

// 授权设备给用户
public static final String SHARE_DEVICE_TO_PERSON = "PROCEDURE.shareDeviceToPerson";

/**
* 授权某个设备给某个用户
* @param userPermission
*/
public boolean shareDeviceToPerson(UserPermission userPermission) {
Map map = new HashMap();
boolean flag = false;
map.put("deviceId", userPermission.getDeviceId());
map.put("deviceType", userPermission.getDeviceType());
map.put("userId", userPermission.getUserId());
map.put("permissionType", userPermission.getPermissionType());
try {
   getSqlMapClientTemplate().insert(SHARE_DEVICE_TO_PERSON, map);
   String result = (String) map.get("result");
   //得到返回值
   if (StringUtil.isNotBlank(result) && "2".equalsIgnoreCase(result)) {
    flag = true;
   }
} catch (Exception e) {
   throw new DaoException("DAOException: " + e);
}
return flag;
}

存储过程的实现代码，嘿嘿。完全不了解，以后有机会学习一下存储过程

create or replace procedure share_dev_prv_to_person(deviceId   in varchar2,
                                                    type       in varchar2,
                                                    permission in varchar2,
                                                    userId     in varchar2,
                                                    result     out varchar2) as

/**
deviceId 设备id
tyoe 设备类型
permission 权限类型
userId 用户id
*/

v_role_id         varchar2(31);
v_organ_id        varchar2(31);
v_permission_id   varchar2(31);
v_type            varchar2(31);
v_permission_type varchar2(200);
v_is_exists       int;
begin

result := '1';

select encodeID(TROLE_SEQ.nextval) into v_role_id from dual;

--convert type
if type = 1 then
    v_type := 'general_camera_vic';
elsif type = 2 then
    v_type := 'ip_camera_vic';
elsif type = 3 then
    v_type := 'alarm_input_channel';
elsif type = 4 then
    v_type := 'alarm_output_channel';
end if;

--convert permission type
if permission = 1 then
    v_permission_type := 'vic_realtime_video_play_operation';
elsif permission = 2 then
    v_permission_type := 'aic_operation';
elsif permission = 3 then
    v_permission_type := 'aoc_open_close_operation';
end if;

-- insert role
begin
    select id
      into v_role_id
      from T_ROLE
     where F_NAME = deviceId || '角色' || type || '_' || permission;

    select 1
      into v_is_exists
      from permission        pp,
           T_ROLE            role,
           R_USER_ROLE       ru,
           R_ROLE_PERMISSION rrp
     where role.f_name = deviceId || '角色' || type || '_' || permission
       and ru.user_id = userId
       and rrp.ROLE_ID = role.id
       and rrp.PERMISSION_ID = pp.id;

exception
    when No_data_found then
      dbms_output.put_line('no role founed!!');

      select organ_id into v_organ_id from t_user where id = userId;

      INSERT INTO T_ROLE
        (ID, F_NAME, NOTE, ORGAN_ID, CREATE_PERSON)
      VALUES
        (v_role_id,
         deviceId || '角色' || type || '_' || permission,
         deviceId || '角色' || type || '_' || permission,
         v_organ_id,
         userId);

      -- grant role permission
      select id
        into v_permission_id
        from permission t
       where t.resource_id = deviceId
         and t.operation = v_permission_type
         and t.resource_type = v_type;

      INSERT INTO R_ROLE_PERMISSION
        (PERMISSION_ID, ROLE_ID)
      VALUES
        (v_permission_id, v_role_id);

      -- grant role to other person
      INSERT INTO R_USER_ROLE
        (ROLE_ID, USER_ID)
      VALUES
        (v_role_id, userId);
end;

commit;

result := '2';

end;

１对于全部是in 类型的参数过程，采用下面的方法调用（ibatis版本是2.3）
比如过程：
Procedure Flashback_Op(v_table_owner Varchar2,v_table_name Varchar2,v_FlashbackScn 　　Number,v_xid Varchar2,v_dbid number);

调用方法：

　　<parameterMap id="tableDml_recycle" class="java.util.Map">
     　 <parameter property="owner" jdbcType="varchar"
        　 javaType="java.lang.String" mode="IN " />
       　 <parameter property="name" jdbcType="varchar"
           　 javaType="java.lang.String" mode="IN " />
     　 <parameter property="scn" jdbcType="NUMBER"
            　javaType="java.math.BigDecimal" mode="IN " />
    　 <parameter property="dbId" jdbcType="NUMBER"
        　 javaType="java.math.BigDecimal" mode="IN " />
    </parameterMap>

    <procedure id="tableDml_zcRecycle" parameterMap="tableDml_caozuo">
        {call TassetREC.Flashback_Op(?,?,?,?,?)}
    </procedure>

　　２对于返回类型是游标 (OUT)的函数，采用如下方式调用。

函数：

　　　Function GetFirstPageNumRows(v_where varchar2,v_dbid Number,v_Numrows varchar2,v_queryid varchar2) return sys_refcursor ;

　　　调用方式：

　<procedure id="firstPage" parameterMap="searchParam">
        {? = call tlgadmin.GetFirstPageNumRows(?,?,?,?)}   （注意返回值在前面用?代表）
    </procedure>

　java代码这么取值：

　　@SuppressWarnings("unchecked")
    public List getAuditSelectByPages(Map map) {
        getSqlMapClientTemplate().queryForList("firstPage", map);//调用
        List arryList = (ArrayList) map.get("result");//取值
        return arryList;
    }

３对于返回值为一般数据类型的函数：

函数：

　　Function DeleteCommand(v_commandid Number,v_commandsetid Number default 0,v_dbid Number default 0) return Number ;

采用如下方式处理（把返回值当作出参来处理ＯＵＴ）：

　<procedure id="Command_deleteById"
        parameterMap="CommandDeleteById">
       { ? = call truleadmin.DeleteCommand(?,?,?)}
    </procedure>
