Question

嗨，我有这个项目在Spring Boot上运行。当我尝试运行时，它给我以下错误：

说明：

com.mycompany.microservice.myproject.bot.controller.BotCommandController中的字段clientCredentialsApi需要一个类型为'org.springframework.web.client.RestOperations'的bean。

操作：

考虑在您的配置中定义类型为“ org.springframework.web.client.RestOperations”的bean。

这是我的代码：

Application.java

package com.mycompany.microservice.myproject
//some imports

@SpringBootApplication`
@ComponentScan(basePackages = "com.mycompany.*")
public class Application {

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

}

这是控制器：

BotCommandController.java
package com.mycompany.microservice.myproject.bot.controller;
//some imports

@RestController
@RequestMapping("/bot-command")
public class BotCommandController {

@Autowired
private RestOperations clientCredentialsApi;

@RequestMapping(value = "/sraix", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody String sraixCommand(@RequestParam(name = "input", required = false) final String input,@RequestParam(name = "cs", required = false) final String cs) throws Exception {

    final UserApiObject userApiObject = clientCredentialsApi.getForObject(env.getProperty("gms.location") + "/rest/user/" + userId, UserApiObject.class);

    return userApiObject.getRole();

}

Answer 1

您正在尝试自动装配未定义或实现的bean。 RestOperations是一个接口，必须实现。

@Autowired
private RestOperations clientCredentialsApi;

Spring正在寻找用@Bean或@Component或@Service注释的类以注入其引用。在您的情况下，您没有定义bean RestOperations，而Spring无法将其注入BotCommandController。

类似这样的东西：

@Bean
RestOperations rest(RestTemplateBuilder restTemplateBuilder) {
    return restTemplateBuilder.basicAuthorization("user", "password").build();
}

需要找不到类型为“ org.springframework.web.client.RestOperations”的bean
