Question

我正在尝试将POJO转换为JSON，将其发布到将返回String的休息控制器。我有以下客户端和服务器的代码。当我运行客户端时，我得到并且错误声明“内容类型'应用程序/ json'不受支持”。我在客户端和服务器上的pom中都有jackson，不确定在哪里尝试

的pom.xml： -

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
</dependency>

休息客户代码： -

public void process() {
    ScriptConfiguration script = new ScriptConfiguration();
    String url = "http://localhost:8080/script-runner/run";
    RestTemplate restTemplate = new RestTemplate();

    // Add MappingJackson2HttpMessageConverter
    restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

    // Prepare HTTPHeaders
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);

    // Prepare HttpEntity
    HttpEntity<String> entity = new HttpEntity<>(headers);

    // Invoke the REST service
    ResponseEntity<String> result = restTemplate.exchange(url,HttpMethod.GET, entity, String.class, script);

    // Get the JSON response body
    System.out.println(result.getBody());
}

RestController

@RestController
public class SynchronousRestController {

@ResponseBody
@RequestMapping(value="/run", consumes = MediaType.APPLICATION_JSON_VALUE)
public String submit(@RequestBody ScriptConfiguration script) throws IOException {

    LOG.info("Received: {}", script);

}

您的方法类型应为POST。将控制器方法更改为：

@ResponseBody
@RequestMapping(value="/run", consumes = MediaType.APPLICATION_JSON_VALUE, method = POST)
public String submit(@RequestBody ScriptConfiguration script) throws IOException {
    LOG.info("Received: {}", script);
    return "success";
}

在您的客户中更改此内容：

// Invoke the REST service
ResponseEntity<String> result = restTemplate.exchange(url, HttpMethod.POST, new HttpEntity<>(script, headers), String.class);

RestTemplate内容类型'application / json'不受支持
