1.在视图微服务product-view的pom.xml中增加
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
2.bootstrap.yml,其中main表示所在分支
spring:
cloud:
config:
label: main
profile: dev
discovery:
enabled: true
serviceId: config-server
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
3.appllication.yml
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
spring:
application:
name: product-view-service-feign
zipkin:
base-url: http://localhost:9411
thymeleaf:
cache: false
prefix: classpath:/templates/
suffix: .html
encoding: UTF-8
servlet:
content-type: text/html
mode: HTML5
4.ProductController
@Controller
@RefreshScope
public class ProductController {
@Autowired
ProductService productService;
@Value("${version}")
String version;
@RequestMapping("/products")
public Object products(Model m) {
List<Product> ps = productService.listProducts();
m.addAttribute("version",version);
m.addAttribute("ps", ps);
return "products";
}
}
5.products
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>products</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<style>
table {
border-collapse:collapse;
400px;
margin:20px auto;
}
td,th{
border:1px solid gray;
}
</style>
</head>
<body>
<div class="workingArea">
<table>
<thead>
<tr>
<th>id</th>
<th>产品名称</th>

</tr>
</thead>
<tbody>
<tr th:each="p: ${ps}">
<td th:text="${p.id}"></td>
<td th:text="${p.name}"></td>
<td th:text="${p.price}"></td>
</tr>
</tbody>
<tr>
<td align="center" colspan="3">
<p th:text="${version}" >zhangdemo springcloud version unknown</p>
</td>
</tr>
</table>
</div>
</body>
</html>
6测试http://localhost:8012/products
ps.显示两条报错信息
（1.org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'eurekaAutoServiceRegistration': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)
(2 java.lang.IllegalArgumentException: Could not resolve placeholder 'version' in value "${version}"
原因：需要将label中的master改为main,git分支在2020.10.01之后分支就默认为main
