Hi,
Our team is trying to upgrade to camel 3.14.4 from camel 2.25.1
We use mybatis with camel-mybatis.
In 2.25.1 was possible to set Map as body to camel parameter binding:
Example:
Mybatis Mapper:
@Insert(value = "INSERT INTO TABLE_X (COL1, COL2, COL2) VALUES (#{col1},
#{col2}, #{col3})")
void insertRecord(
@Param("col1") String col1,
@Param("col2") String col2,
@Param("col3") String col3);
Camel:
.process(exchange -> {
Map<String, String> params = new HashMap<>();
params.put("col1", "a");
params.put("col2", "b");
params.put("col3", "c");
exchange.getIn().setBody(params);
})
.to("mybatis:insertRecord?statementType=Insert&transacted=true")
After migrating to 3.14.4 following error is received:
Caused by: org.apache.ibatis.reflection.ReflectionException: There is no getter
for property named 'col1' in 'class java.util.HashMap$Node'
After having a look on the code looks like issue is caused by
org.apache.camel.support.ObjectHelper used in
org.apache.camel.component.mybatis.MyBatisProducer
MyBatisProducer Line 129 Iterator<?> iter =
ObjectHelper.createIterator(in);
ObjectHelper Line 693 } else if (value instanceof Map) {
Map<?, ?> map = (Map<?, ?>) value;
return map.entrySet();
}
In version 2.25.1 the create iterator did not had this piece of code so it
allowed support to use Map for parameter binding
