Ibatis调用存储过程

Ibatis调用存储过程

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">

<!-- 
- =======================================================
- 授权用户某个设备得权限
- =======================================================
-->
<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>

<procedure id="shareDeviceToPerson" parameterMap="proPermissionDevicePerson">
   <![CDATA[
      {call share_dev_prv_to_person (?,?,?,?,?)}
   ]]>
</procedure>
</sqlMap>

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
