使用Logger JBoss中使用Quarkus中的日志时的错误

Question

下午好，我有一个查询，我从quarkus开始，我在其中使用日志有问题，我正在使用一种使用get动词的简单服务，当放置日志线时，它会给我带来错误java.lang.nullpoInterException。这是我的主要代码：

package com.tmve.subscriber;

import com.tmve.subscriber.repository.FindPrepaidSubscriberICCIDRepository;
import io.agroal.api.AgroalDataSource;
import org.jboss.logging.Logger;

import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import java.util.HashMap;


@Path("/api")
public class FindPrepaidSubscriberICCID {

    @Inject
    AgroalDataSource defaultDataSource;
    Logger log;
    FindPrepaidSubscriberICCIDRepository repository= new FindPrepaidSubscriberICCIDRepository();
    private final String movil="142910399";

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public HashMap<String,String> hello() {
        HashMap<String,String> map=new HashMap<>();
        map=repository.getResources(defaultDataSource,movil);
        log.info("movil: "+movil);
        return map;
    }
}

可能发生的事情，我不明白

Answer 1

您没有注入记录器。您可以将代码更改为：

    @Inject
    AgroalDataSource defaultDataSource;

    @Inject
    Logger log;

顺便说一句，quarkus 提供了一种获得logger的其他方法没有注射：

package com.example;

import io.quarkus.logging.Log; 

class MyService { 
    public void doSomething() {
        Log.info("Simple!"); 
    }
}

Answer 2

@Davide的答案是完全正确的，我只想补充说您可以使用构造函数注入：

private final AgroalDataSource ds;
private final Logger log;

public FindPrepaidSubscriberICCID(AgroalDataSource ds, Logger log) {
   this.ds = ds;
   this.log = log;
}

构造函数注入倾向于简化可测试性（因为您可以创建对象传递间谍或模拟的实例）。它还确保您不会写入托管字段（因为字段是最终的）。
