spring httpinvoker 实践
spring httpinvoker是spring框架的功能，适用于spring框架项目调用另一个spring框架项目。
服务器端：ssh项目
客户端：springboot项目
服务器端配置：
public interface IHelloService {
public String testHttpInvoker();
}
public class HelloServiceImpl implements IHelloService{
@Override
public String testHttpInvoker() {
return "http invoker success";
}
}
springbean.xml:

<mvc:annotation-driven/>
<bean id="helloService"
class="com.service.HelloServiceImpl">
</bean>
<!-- 服务器端httpinvoker 配置 -->
<!--
服务声明：
在Spring配置文件中声明一个HttpInvokerServiceExporter类的bean，共三部分：
--服务名称(如helloExporter)
--服务类型(如com.service.IHelloService)
--服务实现类 helloService-->
<bean name="/helloExporter"
class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
<property name="service" ref="helloService"></property>
<property name="serviceInterface" value="com.service.IHelloService">
</property>
</bean>
</beans>

<!-- 服务器端httpinvoker 配置 -->
<servlet>
<servlet-name>helloExporter</servlet-name>

客户端配置：
package com.contorller;

@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
if(SpringUtil.applicationContext == null) {
SpringUtil.applicationContext = applicationContext;
}
}
//获取applicationContext
public static ApplicationContext getApplicationContext() {
return applicationContext;
}
//通过name获取 Bean.
public static Object getBean(String name){
return getApplicationContext().getBean(name);
}
//通过class获取Bean.
public static <T> T getBean(Class<T> clazz){
