UserServiceImpl.java

    private RestTemplate deleteUserTemplate;
    public void setDeleteUserTemplate(RestTemplate deleteUserTemplate) {
            this.deleteUserTemplate = deleteUserTemplate;
        }

    public void method1() {
    String uri = "some end point url";
    HttpComponentsClientHttpRequestFactory factroy = (HttpComponentsClientHttpRequestFactory) deleteUserTemplate
                        .getRequestFactory();
                deleteUserTemplate.setRequestFactory(factroy);

    String[] userArray = new String[1];
                userArray[0] = "someID123456789";
    // create request body
                JSONObject request = new JSONObject();
                request.put("userIds", userArray);

    // body
                HttpEntity<String> requestEntity = new HttpEntity<String>(request.toString());

    ResponseEntity<String> response = deleteUserTemplate.postForEntity(uri,
                        requestEntity, String.class);

}

作为一个POST类型的服务，我也尝试使用postForObject和交换方法，它不起作用。我想我通过请求机构的方式是错误的。那么如何像{“userIds”那样传递请求体：[“someID123456789”]}

任何人都可以提出你的想法。提前谢谢。
