Jhipster上的java.lang.NoSuchMethodError

Question

I send restTemplate.exchange() from spring-boot project:

RestTemplate restTemplate = new RestTemplate();
        String URI = "http://localhost:8888/getResource";
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
        ResponseEntity<List<PayScreenMenu>> screenMenus = restTemplate.exchange(URI, HttpMethod.GET, null, new ParameterizedTypeReference<List<PayScreenMenu>>() {});

to jhipster method:

@RequestMapping(value = "/getResource", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    public @ResponseBody List<PayScreenMenu> getResource() {
    ....
    return payScreenMenuList;
}

after the return jhipster method returned error:

java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.introspect.AnnotatedMember.getType()Lcom/fasterxml/jackson/databind/JavaType;

on pom.xml jhipster project added version jackson converter:

        <dependency>

            <artifactId>jackson-datatype-hibernate4</artifactId>

Answer 1

The Resource class that the JHipster method is in might be annotated with something like:

@RestController
@RequestMapping("/api")

If that's the case, you need to change String URI = "http://localhost:8888/getResource"; to String URI = "http://localhost:8888/api/getResource"; .
