1 | +## 配置中心客户端,须知: | ||
2 | + | ||
3 | +## 一、bootstrap.yml 模板 | ||
4 | + | ||
5 | +将客户端原来的 application.yml 改成 bootstrap.yml | ||
6 | + | ||
7 | +```yml | ||
8 | +# spring 配置 | ||
9 | +spring: | ||
10 | + cloud: | ||
11 | + config: | ||
12 | + # url地址记得修改 | ||
13 | + uri: http://localhost:8888 | ||
14 | + # 和git中的配置文件里面的服务名,一致 | ||
15 | + name: cgonms-arrival | ||
16 | + # 分支 | ||
17 | + label: master | ||
18 | + # 开发环境 | ||
19 | + profile: dev | ||
20 | + # 与配置中心的security一致 | ||
21 | + username: admin | ||
22 | + password: 123456 | ||
23 | + | ||
24 | +``` | ||
25 | + | ||
26 | +## 注: | ||
27 | + | ||
28 | +git中配置文件的名称,注意点: 查看 | ||
29 | + | ||
30 | +http://118.31.66.166:8099/cloud-config/cloud-config-center/tree/master/respo | ||
31 | + | ||
32 | +## 二、在git中的yml配置文件,一定要有 | ||
33 | + | ||
34 | +```yml | ||
35 | +spring: | ||
36 | + rabbitmq: | ||
37 | + host: 192.168.1.63 | ||
38 | + port: 5672 | ||
39 | + username: mrz | ||
40 | + password: vmvnv1v2 | ||
41 | + | ||
42 | +# boot admin | ||
43 | +management: | ||
44 | + endpoints: | ||
45 | + enabled-by-default: true | ||
46 | + web: | ||
47 | + exposure: | ||
48 | + include: "*" | ||
49 | + endpoint: | ||
50 | + health: | ||
51 | + show-details: always | ||
52 | + shutdown: | ||
53 | + enabled: true | ||
54 | +``` | ||
55 | + | ||
56 | +## 三、配置中心客户端的 pom | ||
57 | + | ||
58 | +```xml | ||
59 | +<dependency> | ||
60 | + <groupId>org.springframework.boot</groupId> | ||
61 | + <artifactId>spring-boot-starter-actuator</artifactId> | ||
62 | +</dependency> | ||
63 | +<dependency> | ||
64 | + <groupId>org.springframework.cloud</groupId> | ||
65 | + <artifactId>spring-cloud-bus</artifactId> | ||
66 | +</dependency> | ||
67 | +<dependency> | ||
68 | + <groupId>org.springframework.cloud</groupId> | ||
69 | + <artifactId>spring-cloud-stream-binder-rabbit</artifactId> | ||
70 | +</dependency> | ||
71 | +``` | ||
72 | + | ||
73 | +## 四、配置中心客户端的启动类 | ||
74 | + | ||
75 | +```java | ||
76 | +/** | ||
77 | + * 和添加配置中心服务之前,一样。没有修改 | ||
78 | + */ | ||
79 | +@EnableScheduling | ||
80 | +@SpringBootApplication | ||
81 | +@MapperScan("com.sunyo.wlpt.cgonms.arrival.mapper") | ||
82 | +@EnableFeignClients | ||
83 | +@EnableEurekaClient | ||
84 | +@EnableTransactionManagement | ||
85 | +public class CgonmsArrivalApplication { | ||
86 | + public static void main(String[] args) { | ||
87 | + SpringApplication.run(CgonmsArrivalApplication.class, args); | ||
88 | + } | ||
89 | +} | ||
90 | +``` | ||
91 | + | ||
92 | +## 五、注意点 | ||
93 | + | ||
94 | +任何使用 @value 读取配置文件信息的所在类的上面,必须要添加上 @RefreshScope | ||
95 | + | ||
96 | +```java | ||
97 | +@RestController | ||
98 | +@RefreshScope | ||
99 | +public class IndexController { | ||
100 | + @Value("${server.ip}") | ||
101 | + private String ip; | ||
102 | + | ||
103 | + @GetMapping("/index") | ||
104 | + public String index(){ | ||
105 | + return ip; | ||
106 | + } | ||
107 | +} | ||
108 | +``` | ||
109 | + |
