Jhipster 上的 java.lang.NoSuchMethodError

Question

我从 spring-boot 项目发送restTemplate.exchange():

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>>() {});

到jhipster方法:

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

返回jhipster方法后返回错误:

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

在 pom.xml jhipster 项目上添加了版本 jackson 转换器:

        <dependency>
            <groupId>com.fasterxml.jackson.datatype</groupId>
            <artifactId>jackson-datatype-hibernate4</artifactId>

Answer 1

JHipster 方法所在的 Resource 类可能带有如下注释:

@RestController
@RequestMapping("/api")

如果是这种情况，您需要将 String URI = "http://localhost:8888/getResource"; 更改为 String URI = "http://localhost:8888/api/getResource";.
