Java项目之间接口调用方式

一、服务提供接口

@RestController
@RequestMapping("/")
public class TransferController {

    @Value("${server.port}")
    private String serverPort;

    @Resource
    private TransferService transferService;

    @GetMapping(value = "test")
    public CommonResult test() {
        return new CommonResult(200, "校验通过,serverPort: " + serverPort);
    }

    @PostMapping(value = "transfer")
    public CommonResult transfer(@RequestParam(name = "content") String content) {
        YlContent ylContent = YlContent.builder().content(content).build();
        transferService.save(ylContent);
        return new CommonResult(200, "成功,serverPort: " + serverPort, ylContent);
    }

    @PostMapping(value = "transfer2")
    public CommonResult transfer2(@RequestBody YlContent ylContent) {
        transferService.save(ylContent);
        return new CommonResult(200, "成功,serverPort: " + serverPort, ylContent);
    }
}

二、消费调用方
1.通过RestTemplate调用，传参测试为拼接数据

/**
 * 测试
 */
@GetMapping("/consumer/transfer")
public CommonResult<Payment> transfer(){
    HttpHeaders headers = new HttpHeaders();
    RestTemplate template =new RestTemplate();
    headers.add("Content-Type", "application/json;charset=UTF-8");
    headers.add("Accept", "application/json");//请求头
    headers.add("token", "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJjbHBzLWpkLWFnZW50X3lsIiwidXNlck5hbWUiOiJjbHBzLWpkLWFnZW50IiwiaWF0IjoxNjI5Nzk4MTQyfQ.yickp5DLNR4c-OU7KLTpvj7rjySLtv8HlPRnn-ZVlyk");//请求头
    String content = "测试asdfsafas";
    HttpEntity requestEntity = new HttpEntity(content);
    return restTemplate.postForObject("http://localhost:9001/transfer?content="+content,requestEntity, CommonResult.class);
}

　　
2.通过RestTemplate调用，传参格式为Json字符串。

/**
 * 测试
 */
@GetMapping("/consumer/transfer")
public CommonResult<Payment> transfer(){
    HttpHeaders headers = new HttpHeaders();
    RestTemplate template =new RestTemplate();
    headers.add("Content-Type", "application/json;charset=UTF-8");
    headers.add("Accept", "application/json");//请求头
    headers.add("token", "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJjbHBzLWpkLWFnZW50X3lsIiwidXNlck5hbWUiOiJjbHBzLWpkLWFnZW50IiwiaWF0IjoxNjI5Nzk4MTQyfQ.yickp5DLNR4c-OU7KLTpvj7rjySLtv8HlPRnn-ZVlyk");//请求头
    MultiValueMap<String, String> postParameters = new LinkedMultiValueMap<String, String>();
    postParameters.add("content", "30001821");
    HttpEntity requestEntity = new HttpEntity(
            data, headers);
    return restTemplate.postForObject("http://localhost:9001/transfer2",requestEntity, CommonResult.class);
}
3.通过HttpClient方式调用，略。
