I am trying to use spring data rest in my project, I prefer to use xml config instead of using spring boot, this is what I am doing:
in POM:
- spring: 4.1.4.RELEASE
- spring-hateoas: 0.16.0.RELEASE
- spring-data-rest-webmvc:2.2.2.RELEASE
In web.xml:
<servlet>
<servlet-name>rest</servlet-name>
<servlet-class>org.springframework.data.rest.webmvc.RepositoryRestDispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
- Repository:
@RepositoryRestResource(collectionResourceRel = "testcases", path = "testcases")
public interface ITestCaseRepository extends CrudRepository<TestCase, Long> {
List<TestCase> findByName(String name);
@Query("SELECT t from TestCase t WHERE LOWER(t.name) = LOWER(?1) AND t.type = ?2")
List<TestCase> myFindByNameANDType(String name, TestCaseType type);
List<TestCase> findByNameANDType(String name, TestCaseType type);
}
When I visit http://localhost:8080/rest, I got this error:
HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.ser.std.MapSerializer.construct([Ljava/lang/String;Lcom/fasterxml/jackson/databind/JavaType;ZLcom/fasterxml/jackson/databind/jsontype/TypeSerializer;Lcom/fasterxml/jackson/databind/JsonSerializer;Lcom/fasterxml/jackson/databind/JsonSerializer;Ljava/lang/Object;)Lcom/fasterxml/jackson/databind/ser/std/MapSerializer;
It describes that the server encountered an internal error that prevented it from fulfilling this request.
The exception:
