Question

我有一个项目需要使用REST / JSON服务公开我的服务。我使用Spring Boot来开发控制器，然后我通过HTTP Invoker代理注入服务。这个想法起作用，因为我使用XML配置使用基本的Spring 3.2应用程序。但是，我在将HTTP Invoker代理导入Spring Boot应用程序时遇到问题。将它们注入控制器时，它无法找到相关的bean。

错误（使用Gradle构建时的基本单元测试）：

HTTP Invoker代理在Java配置中配置：

@Configuration
public class HttpServicesConfig {
    @Value("${flashtp.ipaddress}")
    private String ipAddress;
    @Value("${flashtp.httpservices.port}")
    private String port;
    @Bean
    public CloseableHttpClient httpClient() {
        HttpClientBuilder builder = HttpClientBuilder.create();
        builder.setMaxConnPerRoute(60);
        builder.setMaxConnTotal(60);
        RequestConfig requestConfig =
            RequestConfig.custom().setConnectTimeout(10000)
                                  .setConnectionRequestTimeout(10000)
                                  .setSocketTimeout(10000)
                                  .build();
        builder.setDefaultRequestConfig(requestConfig);
        CloseableHttpClient httpClient = builder.build();
        return httpClient;
    }
    @Bean
    public HttpComponentsHttpInvokerRequestExecutor httpClientExecutor() {
        HttpComponentsHttpInvokerRequestExecutor executor = 
            new HttpComponentsHttpInvokerRequestExecutor();
        executor.setConnectTimeout(10000);
        executor.setHttpClient(httpClient());
        return executor;
    }

    .....

    @Bean
    public HttpInvokerProxyFactoryBean prePaidAirtimeService() {
        HttpInvokerProxyFactoryBean b = new HttpInvokerProxyFactoryBean();
        b.setServiceInterface(PrePaidAirtimeService.class);
        b.setServiceUrl(
            "http://" + ipAddress + ":" + port +
            "/flash-http-services/remoting/prePaidAirtimeService");
        b.setHttpInvokerRequestExecutor(httpClientExecutor());
        return b;
    }
}

然后将此配置导入主应用程序配置：

@Configuration
@Import(HttpServicesConfig.class)
@ComponentScan(basePackages = { "za.co.flash.openapi" })
@EnableAutoConfiguration(exclude = {
    SecurityAutoConfiguration.class,
    HibernateJpaAutoConfiguration.class
    })
public class Application {

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

我不确定我做错了什么。

此致

这种在Spring Java配置中配置HTTP Invoker的方法解决了这个问题：

@Bean
public PrePaidAirtimeService prePaidAirtimeService() {
    HttpInvokerProxyFactoryBean f = new HttpInvokerProxyFactoryBean();
    f.setServiceInterface(PrePaidAirtimeService.class);
    f.setServiceUrl(
        "http://" + ipAddress + ":" + port +
        "/flash-http-services/remoting/prePaidAirtimeService");
    f.setHttpInvokerRequestExecutor(httpClientExecutor());
    f.afterPropertiesSet();
    return (PrePaidAirtimeService) f.getObject();
}

谢谢@M。 Deinum指出我正确的方向。
