spring httpinvoker是spring框架的功能，適用於spring框架項目調用另外一個spring框架項目。java

服務器端：ssh項目mysql

客戶端：springboot項目web

服務器端配置：redis

public interface IHelloService {
public String testHttpInvoker();

}spring

public class HelloServiceImpl implements IHelloService{

   @Override
   public String testHttpInvoker() {
       return "http invoker success";
   }

}sql

<!--spring-mvc

服務聲明：springboot

在Spring配置文件中聲明一個HttpInvokerServiceExporter類的bean，共三部分：

--服務名稱(如helloExporter)

--服務類型(如com.service.IHelloService)

--服務實現類 helloService-->

web.xml:

<servlet>
        <servlet-name>helloExporter</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springbean.xml</param-value>
      </init-param>
      <load-on-startup>3</load-on-startup>
   </servlet>
   <servlet-mapping>
            <servlet-name>helloExporter</servlet-name>
            <url-pattern>/remoting/*</url-pattern>
      </servlet-mapping>

客戶端配置：

package com.contorller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import com.service.IHelloService;
import com.util.SpringUtil;

@RestController
public class HelloController {

   @GetMapping("/testHttpinvoker")
   public String testHttpinvoker(){
       IHelloService iHelloService = SpringUtil.getBean("remoteHelloService",IHelloService.class);
       return iHelloService.testHttpInvoker();
   }
}

public interface IHelloService {
public String testHttpInvoker();

}

package com.util;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class SpringUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        if(SpringUtil.applicationContext == null) {
            SpringUtil.applicationContext = applicationContext;
        }

    }

    //獲取applicationContext
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    //經過name獲取 Bean.
    public static Object getBean(String name){
        return getApplicationContext().getBean(name);
    }

    //經過class獲取Bean.
    public static <T> T getBean(Class<T> clazz){
        return getApplicationContext().getBean(clazz);
    }

    //經過name,以及Clazz返回指定的Bean
    public static <T> T getBean(String name,Class<T> clazz){
        return getApplicationContext().getBean(name, clazz);
    }

}

application-bean.xml：

<?xml version="1.0" encoding="UTF-8"?>

        <property name="serviceUrl" value="http://localhost:8088/sshAndRedis/remoting/helloExporter" />

<property name="serviceInterface" value="com.service.IHelloService" />
   </bean>


</beans>

@SpringBootApplication
@ImportResource(locations= {"classpath:application-bean.xml"})
public class RunApplication {
   public static void main(String[] args){

       SpringApplication.run(RunApplication.class, args);
   }
