How to use custom ObjectMapper?
- Create new Class and implement Interface EntityMapper
public class CustomEntityMapper implements EntityMapper { public CustomEntityMapper(){ //custom configuration/implementation (e.g. FasterXML/jackson) } @Override public String mapToString(Object object) throws IOException { //mapping Object to String return null; } @Override public <T> T mapToObject(String source, Class<T> clazz) throws IOException { //mapping String to Object return null; } } - Define new bean and inject it into ElasticsearchTemplate
<bean name="elasticsearchTemplate" class="org.springframework.data.elasticsearch.core.ElasticsearchTemplate"> <constructor-arg name="client" ref="client"/> <constructor-arg name="entityMapper" ref="entityMapper"/> </bean> <bean name="entityMapper" class="org.springframework.data.elasticsearch.core.CustomEntityMapper"/> - Inject your custom implementation to template
