1.引入Mavan依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.hateoas</groupId>
<artifactId>spring-hateoas</artifactId>
</dependency>
2.actuator 相关配置
修改application.yml文件
server:
port: 8081
spring:
application:
name: springboot
## actuator配置
management:
endpoints:
web:
cors: # 跨域处理
allowed-origins: '*'
allowed-methods: '*'
allow-credentials: true
base-path: /manage # 访问路径 为 http://ip:port/monitor/manage
exposure:
include: '*'
enabled-by-default: false
server:
servlet:
context-path: /monitor # 访问路径 为 http://ip:port/monitor
port: 1234 # management 的端口 http://ip:1234 如果不想通过HTTP公开端点，则可以将管理端口设置为-1，如以下示例所示：
endpoint: #暴露出的endpoint
shutdown:
enabled: false # shutdown 可以关闭制定的端点 除shutdown以外的所有端点均已启用
info:
enabled: true
health:
enabled: true
show-details: always #展示详情
metrics:
enabled: true
health:
db:
enabled: false #关闭默认配置的db检查
redis:
enabled: false
# /actuator/info 的信息的配置
info:
name: @project.artifactId@
encoding: @project.build.sourceEncoding@
java:
source: @java.version@
target: @java.version@
3.配置完成项目
访问路径
http://ip:port/context-path/base-path/**
4.扩展actuator的监控功能
自定义endPoint
/**
* @describe: 自定义端点暴漏此端点需要设置 management.endpoints.web.exposure.include=*
*/
@Endpoint(id = "person")
@Component
public class MyEndpoint {
private final Map<String, Person> people = new ConcurrentHashMap<>();
MyEndpoint() {
this.people.put("name1", new Person("n1"));
this.people.put("name2", new Person("n2"));
this.people.put("name3", new Person("3"));
}
@ReadOperation
public List<Person> getAll() {
return new ArrayList<>(this.people.values());
}
@ReadOperation
public Person getPerson(@Selector String name) {
return this.people.get(name);
}
@WriteOperation
public void addOrUpdatePerson(@Selector String name, @Selector String person) {
this.people.put(name, new Person(person));
}
class Person {
private String name;
Person(String name) {
this.name = name;
}
public String getName() {
return this.name;
}
}
}
对health的扩展~实现接口方式
@Component("myHealth_interface")
public class MyHealthIndicator implements HealthIndicator {
@Override
public Health health() {
//健康检查实现
int errorCode = check();
if (errorCode != 0) {
return Health.down().withDetail("Error Code", errorCode).build();
}
return Health.up().build();
}
/**
* 健康检查实现
*/
public int check(){
return 0;
}
}
对health的扩展~实现接口方式~实现抽象类
@Component("myHealth_abstract")
public class MyHealthIndicator1 extends AbstractHealthIndicator {
@Override
protected void doHealthCheck(Health.Builder builder) throws Exception {
builder.up().withDetail("xxx", "xxxyyy");
}
}
扩展info信息
public class MyContributor implements InfoContributor {
@Value("${spring.application.name}")
private String applicationName;
@Override
public void contribute(Info.Builder builder) {
builder.withDetail("Application-info", Collections.singletonMap("name", applicationName));
}
}
public class MyContributor implements InfoContributor {
@Value("${spring.application.name}")
private String applicationName;
@Override
public void contribute(Info.Builder builder) {
builder.withDetail("Application-info", Collections.singletonMap("name", applicationName));
}
}
