spring-boot - Spring Boot 节俭

问题描述

我正在关注本教程https://dzone.com/articles/building-microservices-spring在 Spring 上使用节俭。当我运行本教程时，它运行良好，但是当我做一个示例时，它没有进行正确的映射。

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class CacheApplication {

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

@Bean
public TProtocolFactory tProtocolFactory() {
    return new TBinaryProtocol.Factory();
}

@Bean
public Servlet cache(TProtocolFactory protocolFactory, CacheServiceHandler handler) {
    return new TServlet(new TCacheService.Processor<>(handler), protocolFactory);
}


}

这是我的主要内容，当我启动服务器时，它会显示“Servlet 缓存映射到 [/]”，而它应该是“Servlet 缓存映射到 [/cache/]”

本教程在 gradle 上，但我使用的是 maven

运行服务器我没有收到错误，但是当我使用此代码运行客户端时

@EnableAutoConfiguration
@ComponentScan(basePackageClasses = {CacheApplication.class})

public class ClientTest {
    protected int port;

    @Autowired
    protected TProtocolFactory protocolFactory;

    public static void main(String[] args)  throws Exception {
        new SpringApplicationBuilder().sources(ClientTest.class).profiles("client").web(false).run(args);

    }
    @Bean
    public String test() throws Exception{
        TTransport transport= new THttpClient("http://localhost:8080/cache/");
        TProtocol protocol = protocolFactory.getProtocol(transport);
        TCacheService.Client client;
        client = new TCacheService.Client(protocol);
        return client.query(10);
    }

}

这是我得到的错误：

解决方案

设法通过修改servlet bean来解决它，如下所示：

@Bean
public ServletRegistrationBean cache(TProtocolFactory protocolFactory, CacheServiceHandler handler) {
    TServlet servlet = new TServlet(new TCacheService.Processor<SampleServiceControllerHandler>(handler), protocolFactory);
    return new ServletRegistrationBean(servlet, "/cache");
}
