在原來的消費者專案api下，更換App類和controller類

1、新APP類

package z3.cloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication
@EnableEurekaClient
public class ApiRestApp {
	public static void main(String[] args) {
		SpringApplication.run(ApiRestApp.class, args);
    }
	@Bean
	@LoadBalanced
	public RestTemplate restTemplate() {
	   // Do any additional configuration here
	   return new RestTemplate();
	}
}
 

2、更換controller類

package z3.cloud;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
@RequestMapping("/rest")
public class LoginRestController {
	@Autowired
	RestTemplate restTemplate;

	@RequestMapping("/login")
	public String login() {
		String url = "http://oauth2/auth";
		return restTemplate.getForObject(url, String.class);
	}
}
