SpringBoot 定时访问外部接口时Tomcat报404错误.

Question

想实现定时(每秒)主动访问一次外部的接口,并读取数据,但是程序在容器中运行时报了HttpClientErrorException$NotFound: 404 null的错误,请问各位是什么问题呢?

启动类中的代码

@SpringBootApplication
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@MapperScan(value = "com.luchao.springbootmybatis.mapper")
@EnableScheduling

public class SpringbootMybatisApplication {

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

}

controller中的代码:

@Controller
public class ClientLicenseController {

@Autowired
private RestTemplate restTemplate;

@Scheduled(fixedRate = 1000)
@ResponseBody
public void book() {

    System.out.println("ok");

    String paraStr = "db48e27052f54879b50f3edce4fc19bb";

    String strReponse = restTemplate.postForObject("http://localhost:8080/getCpInfo/",paraStr, String.class);       

}

}

控制台的错误日志:

2019-03-13 18:00:20.353 ERROR 772 --- [ scheduling-1] o.s.s.s.TaskUtils$LoggingErrorHandler : Unexpected error occurred in scheduled task.

Answer 1

在你的启动类里面加上下面这段代码：

@Autowired
private RestTemplateBuilder builder;

@Bean
public RestTemplate restTemplate() {
    return builder.build();
}
