Question

i make mybatis sqllog intercepor in my project.
in case. #{__frch_CUST_0} #{__frch_CUST_1} ~~~ #{__frch_CUST_N}
how can i get parameters value "__frch_CUST_n" ?
// mybatis interceptor sql log function
public String getSqlLog(StatementHandler handler)
{
String sql = handler.getBoundSql().getSql();
Object param = handler.getParameterHandler().getParameterObject();
List<ParameterMapping> paramMapping = handler.getBoundSql().getParameterMappings();
// change \? value to replace point
for(ParameterMapping mapping:paramMapping)
{
sql = sql.replaceFirst("\\?", "#{"+mapping.getProperty()+"}");
}
for(ParameterMapping mapping:paramMapping)
{
String sqlparam = "#{"+mapping.getProperty()+"}";
String sqlparamname = mapping.getProperty();
Object sqlparamvalue = ((Map) param).get(sqlparamname);
if( !sqlparamname.startsWith("__frch_") )
{
if(isNull(sqlparamvalue))
{
sql = sql.replace(sqlparam, "NULL");
}
else
{
if(sqlparamvalue instanceof String)
{
try
{
sql = sql.replace(sqlparam, "'"+getSQLString(sqlparamvalue.toString())+"'");
}
catch(Exception e)
{
sql = sql.replace(sqlparam, "'"+getSQLString(sqlparamvalue.toString())+"'");
}
}
else
{
sql = sql.replace(sqlparam, sqlparamvalue.toString());
}
}
}
else
{
**// HOW CAN I DO HERE?**
}
}
return sql;
}
thank you for read my question..

Answer 1

i resolve my self.
mybatis make new arrayList parameter. and use it.
example list value
DATE = ['20180101','20180102','20180103'];
STEP = ['PLAN', 'MAKE', 'SETUP'];
__frch_DATE_0
__frch_DATE_1
__frch_DATE_2
__frch_STEP_3
__frch_STEP_4
__frch_STEP_5
mybatis __frch_ = ['20180101','20180102','20180103','PLAN', 'MAKE', 'SETUP']
so i use it. my question is resolved..
