# 项目接入到SOP
5 years ago
以springboot项目为例,完整项目可参考sop-example下的sop-story
- pom.xml添加版本配置
```xml
<properties>
4 years ago
<!-- springboot 版本-->
<spring-boot.version>2.2.5.RELEASE</spring-boot.version>
<!-- spring cloud 版本 -->
<spring-cloud.version>Hoxton.SR3</spring-cloud.version>
<!-- spring cloud alibaba 版本 -->
<!-- 具体版本对应关系见:https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E -->
<spring-cloud-alibaba.version>2.2.1.RELEASE</spring-cloud-alibaba.version>
5 years ago
</properties>
```

- application.properties配置文件添加

5 years ago
```properties
server.port=2222
spring.application.name=story-service
5 years ago
# nacos注册中心
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848
6 years ago
```
- 在springboot启动类上添加`@EnableDiscoveryClient`
- 新增一个配置类,继承`AlipayServiceConfiguration.java`,内容为空
```java
@Configuration
public class OpenServiceConfig extends AlipayServiceConfiguration {
}
```
到此准备工作就完成了,接下来可前往`新增接口`查看如何新增接口。
## 非Java项目接入
如果是非Java项目接入,如php,需要做到以下几点:
5 years ago
> 1. 提供路由配置接口
> 2. 服务注册到nacos,并在nacos的metadata中指定接口路径,metadata的key为:`sop.routes.path`
- 提供路由配置接口
php应用提供的接口需要返回如下json内容:
```json
{
5 years ago
"serviceId": "goods-service",
"createTime": 1568603471646,
"updateTime": 1568603471646,
"description": null,
"routeDefinitionList": [
{
5 years ago
"id": "goods.list1.0",
"name": "goods.list",
"version": "1.0",
5 years ago
"uri": "lb://goods-service",
5 years ago
"path": "/goods/list_goods",
"order": 0,
"ignoreValidate": 0,
"status": 1,
"mergeResult": 1,
"permission": 0
},
...
]
}
```
json参数说明
|参数名|是否必填|说明|
|:----|:----|:----|
|serviceId |是|serviceId,服务id |
|createTime |是|创建时间,Unix timestamp,毫秒 |
|updateTime |是|修改时间,Unix timestamp,毫秒 |
|description|否|描述|
|routeDefinitionList元素参数说明|是|路由配置,见:routeDefinitionList元素参数说明|
routeDefinitionList元素参数说明
|参数名|是否必填|说明|
|:----|:----|:----|
|id |是|路由id,全局唯一,格式:接口名+版本号 |
|name|是|接口名称|
|version|是|版本号|
5 years ago
|uri|是|格式:lb:// + serviceId,如:lb://goods-service|
5 years ago
|path|是|接口path,填端口号后面的path,如你的接口为`http://open.domain.com:8080/goods/list_goods`,填:`/goods/list_goods`|
|order|是|固定填:0|
|ignoreValidate|是|忽略签名验证,1:是,0:否|
|status|是|启用状态,1:启用,2:禁用|
|mergeResult|是|是否统一返回结果,1:是,0:否|
|permission|是|是否需要权限访问,1:是,0:否|
- 服务注册到nacos
可前往nacos官网,参考[open-api](https://nacos.io/zh-cn/docs/open-api.html),使用nacos提供的接口完成服务注册
- 在nacos的metadata中指定接口路径
伪代码如下:
```java
Instance instance = new Instance();
5 years ago
instance.setServiceName("goods-service");
instance.setIp("192.168.0.11");
instance.setPort(8080);
// 在nacos的metadata中指定接口路径
instance.getMetadata().put("sop.routes.path", "/goods/list_goods");
namingService.registerInstance(serviceId, instance);
```
完成以上步骤后,php服务注册到nacos,网关会触发监听事件,获取新注册的服务,然后会向你的服务拉取路由配置。
