I had a look at the JIRA issue you created for this.
The JacksonMappingProvider is used only to read the Json, not to write it.
With jsonpathWriteAsString, you'd need to register an ObjectMapper which
customizes the serialization of the double values. By default, Jackson
will use the standard Java String representation for a double which uses
the scientific notation.
When using jsonpath(), the result type in your example is actually a Map
where the values are Doubles. log("${body}") doesn't use an ObjectMapper
at all; it just converts the keys and values to a String.
However you could use a customer processor to format the Doubles as you
want. For example:
.jsonpath("$").process(new Processor() {
public void process(Exchange exchange) {
Object body = exchange.getIn().getBody();
if (body instanceof Map) {
for (Object value : ((Map)body).values()) {
if (value instanceof Double) {
String d = String.format("%12.2f", value);
...
Is that helpful?

OK, will do that.
However if I use jsonpathWriteAsString then it uses a global Objectmapper but
still my problem exists with the numerics, but that is maybe another issue !?

Hi
I have discovered that when using JSONPath in a route, the implementation does
not use any ObjectMapper registered, it uses it's own.
--------------------------------------------
JacksonMappingProvider.class
public class JacksonMappingProvider implements MappingProvider {
private final ObjectMapper objectMapper;
public JacksonMappingProvider() {
this(new ObjectMapper());
}
public JacksonMappingProvider(ObjectMapper objectMapper) {
this.objectMapper = objectMapper;
}
----------------------------------------------
Is this the intended solution or should we make JSONPath use any globally
registered mapper as an option?
I have an issue when using JSONPath and my values are numerics and large
decimal format like 123.456789. They get parsed as Double and then when
representing the json string they are in scientific notation.
The use of Jackson Features are not available.
When using json as Dataformat we can register a global Objectmapper and use
that but when using JSONPath it is not implemented.
My Camel version is 3.14.1
