@SpringBootApplication(exclude=DataSourceAutoConfiguration.class)

    @Bean 
    public RestTemplate restTemplate() {
        HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory();

    public static void main(String[] args) {
        SpringApplication.run(App.class,args);
    }
}

通过依赖注入注入resttemplate 控制者 @RestController @RequestMapping（“ / carlock”） //允许跨域访问 @CrossOrigin（origins =“ *”，maxAge = 3600）公共类LockController { //注入RestTemplate 私有最终RestTemplate restTemplate; @Autowired 公共LockController（RestTemplate restTemplate）{ this.restTemplate = restTemplate; }

                    "https://xxx-test.xxx.xin/xx/api/v2/lockCar/entity",

The expectation is to return a json string
