Micro-mvc不但可以与springmvc整合还可以与springcloud整合
Springcloud的controller层改为接口注解仍使用springcloud和springboot相关注解实现服务注册路由等配置,但controller接口上需要添加@InjectGroovy注解设置接口实现的关联groovy。
package com.nh.micro.springcloud.demo.web;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import com.nh.micro.service.InjectGroovy;
@InjectGroovy(name="ComputeGroovy")
@RestController
public interface ComputeController {
@RequestMapping(value = "/add" ,method = RequestMethod.GET)
@ResponseBody
public Integer add(@RequestParam(value="a") Integer a, @RequestParam(value="b") Integer b);
}
Spring配置中使用GroovyBeanScannerConfigurer扫描controller接口
<bean class="com.nh.micro.service.GroovyBeanScannerConfigurer">
<property name="scanPath" value="com.nh.micro.springcloud.demo.web"></property>
</bean>
ComputeController接口实现ComputeGroovy.groovy
package groovy
import javax.annotation.Resource;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.RequestParam;
import org.apache.log4j.Logger;
class ComputeGroovy {
private final Logger logger = Logger.getLogger(getClass());
//@Resource(name="discoveryClient")
//public DiscoveryClient client;
public Integer add(@RequestParam Integer a, @RequestParam Integer b) {
//GroovyExecUtil.execGroovyRetObj("TestGroovy", "test");
Integer r = a + b;
System.out.println(r);
//ServiceInstance instance = client.getLocalServiceInstance();
//logger.info("/add, host:" + instance.getHost() + ", service_id:" + instance.getServiceId() + ", result:" + r);
return r;
}
}
启动DemoServiceApplication,访问http://localhost:2222/add?a=1&b=2
