spring-cloud-invoker-parent
介绍
目前只支持 spring boot 2.0 + 版本
一个简单轻量的rpc框架,不使用任何注册中心。
目前spring-cloud-starter-invoker使用http方式引用htppInvoker模块实现service暴露,从而实现远程调用功能。
并基于eureka、nacos基本原理,获取注册中心“服务模块”IP地址。同时也支持项目中,没有注册中心场景下的项目。
更新说明
1、 2.0.0 开启spring boot 2.0 + 版本支持
2、 2.0.1 主要新增实例,整理invoker代码,修改2.0.0遗留bug。新增支持oauth2验证
application.yml 配置
http:
invoker:
connectionRequestTimeout: 15000
connectTimeout: 20000
readTimeout: 15000
maxQueueSize: 1000
remote:
enabled: false
maven
- pom.xml 添加如下代码
<dependency> <groupId>com.sample</groupId> <artifactId>spring-cloud-starter-invoker</artifactId> <version>${project.version}</version> </dependency>
使用说明1、 启动类
@SpringBootApplication
@EnableDiscoveryClient
@EnableRemoteClients
@ComponentScan(basePackages={"com.xxx"})
public class TestBootstrap {
public static void main(String[] args) {
final ConfigurableApplicationContext run = SpringApplication.run(TestBootstrap.class);
}
}
2、 暴露service
@RemoteService
public class TestService implements TestServiceFacade {
public String test(){
return "ok";
}
}
3、 添加接口与熔断,并指向模块调用注册中心地址进行远程访问
3.1) 有注册中心下使用,如果没有项目名(projectPath)则为空或不填写
@RemoteClient(name = "cx-test",fallback = TestServiceFacadeHystrix.class, projectPath = "/projectName")
public interface TestServiceFacade {
public String test();
}
public class TestServiceFacadeHystrix implements TestServiceFacade{
public String test(){
return "ok";
}
}
3.2) 非注册中心下使用,如果没有项目名(projectPath)则为空或不填写
@RemoteClient(address = "127.0.0.1:8080",fallback = TestServiceFacadeHystrix.class, projectPath = "/projectName")
public interface TestServiceFacade {
public String test();
}
public class TestServiceFacadeHystrix implements TestServiceFacade{
public String test(){
return "ok";
}
}
4、 客服端使用接口
@RestController
@RequestMapping("/test")
public class ChatController {
@Autowired
private TestServiceFacade testServiceFacade;
@RequestMapping("/test")
public String test(){
return testServiceFacade.test();
}
}
5、oauth2 服务调用验证
@Component
public class RequestInterceptor implements HttpInvokerRequestInterceptor {
@Override
public void apply(RequestTemplate requestTemplate) {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if ((authentication instanceof AbstractAuthenticationToken)) {
AbstractAuthenticationToken aat = (AbstractAuthenticationToken)authentication;
if ((aat.getDetails() instanceof OAuth2AuthenticationDetails)) {
OAuth2AuthenticationDetails details = (OAuth2AuthenticationDetails)aat.getDetails();
requestTemplate.addHeaders("Authorization", new String(String.format("%s %s", new Object[] { details.getTokenType(), details.getTokenValue() })));
}
}
}
}
