spring - 导入 org.springframework.boot.actuate.metrics.CounterService 无法解析

Question

早些时候我使用spring-boot-starter-parent版本1.5.7.RELEASE，当我将依赖项升级到2.0.4.RELEASE时，出现以下错误：导入

org.springframework.boot.actuate.metrics.CounterService 无法解决

此外，Spring Data Mongo 也有更新：

QueryByExampleExecutor 类型中的方法 findOne(Example) 不适用于参数 (String)

CrudRepository 类型中的方法 delete(Person) 不适用于参数 (String)

我很确定，org.springframework.boot.actuate.metrics.CounterService在 Spring v2.0.x.RELEASE 中已弃用。

任何指针什么是这个类的替换？或者我现在可以调整我的逻辑吗？

PersonCounterService.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.actuate.metrics.CounterService;
import org.springframework.stereotype.Service;

@Service
public class PersonCounterService {

    private final CounterService counterService;

    @Autowired
    public PersonCounterService(CounterService counterService) {
        this.counterService = counterService;
    }

    public void countNewPersons() {
        this.counterService.increment("services.person.add");
    }

    public void countDeletedPersons() {
        this.counterService.increment("services.person.deleted");
    }

}

人控制器.java

@RestController
@RequestMapping("/person")
public class PersonController {

    @Autowired
    private PersonRepository repository;
    @Autowired
    private PersonCounterService counterService;

    @GetMapping
    public List<Person> findAll() {
        return repository.findAll();
    }

    @GetMapping("/{id}")
    public Person findById(@RequestParam("id") String id) {
        return repository.findOne(id);
    }

    @PostMapping
    public Person add(@RequestBody Person p) {
        p = repository.save(p);
        counterService.countNewPersons();
        return p;
    }

    @DeleteMapping("/{id}")
    public void delete(@RequestParam("id") String id) {
        repository.delete(id);
        counterService.countDeletedPersons();
    }

    @PutMapping
    public void update(@RequestBody Person p) {
        repository.save(p);
    }

    @GetMapping("/lastname/{lastName}")
    public List<Person> findByLastName(@RequestParam("lastName") String lastName) {
        return repository.findByLastName(lastName);
    }

    @GetMapping("/age/{age}")
    public List<Person> findByAgeGreaterThan(@RequestParam("age") int age) {
        return repository.findByAgeGreaterThan(age);
    }
}

Micrometer 现在已集成到 spring boot 2.0 中。在这里阅读更多：千分尺-Springboot

使用 MetricRegistry 调整逻辑

@Bean
MeterRegistryCustomizer<MeterRegistry> addPersonRegistry() {
    return registry -> registry.config().namingConvention().name("services.person.add", Type.COUNTER);
}

@Bean
MeterRegistryCustomizer<MeterRegistry> deletePersonRegistry() {
    return registry -> registry.config().namingConvention().name("services.person.deleted", Type.COUNTER);
}


@Service
public class PersonCounterService {

    private final Counter personAddCounter;
    private final Counter personDeleteCounter;

    public PersonCounterService(MeterRegistry registry) {       
        this.personAddCounter = registry.counter("services.person.add");
        this.personDeleteCounter = registry.counter("services.person.deleted");
    }

    public void countNewPersons() {     
        this.personAddCounter.increment();
    }

    public void countDeletedPersons() {
        this.personDeleteCounter.increment();
    }

}

最后，点击执行器端点以查看指标：

/actuator/metrics/services.person.add

{"name":"services.person.add","description":null,"baseUnit":null,"measurements":[{"statistic":"COUNT","value":1.0}],"availableTags":[]}
