 Java代码：
 public class SystemInfoCache {

    public void init(){
        sysInfoCacheMap = new HashMap();
        List sysList = sqlMapExecutor.queryForList("core.querySysInfoList");
        for(int i=0;i<sysList.size();i++){
            Map sysMap = (Map)sysList.get(i);
            sysInfoCacheMap.put(sysMap.get("name"), sysMap.get("value"));
        }
    }
    public void setSqlMap(SqlMapClientOperations sqlmapclientoperations) {
        this.sqlMapExecutor = sqlmapclientoperations;

    }

    private SqlMapClientOperations sqlMapExecutor;
    public static Map sysInfoCacheMap;

}

<resultMap class="java.util.HashMap" id="sysInfoList">
    <result property="name" column="name"/>
    <result property="value" column="valueOf"/>
</resultMap>
<select id="querySysInfoList" resultMap="sysInfoList">
    select name,valueOf from ocs_sysinfo
</select>

--- The error occurred in config/sql-mapping/coreSql.xml.
这个错误发生在config/sql-mapping/coreSql.xml文件中
--- The error occurred while applying a result map.
在进行结果映射时产生的
--- Check the core.sysInfoList.
检查core.sysInfoList
--- Check the result mapping for the 'name' property.
检查name属性的映射
