Spring Boot开发 之 日志部署

开始

spring init -dweb --build gradle SpringBootDeploy && cd SpringBootDeploy

vim src/main/java/com/example/SpringBootDeploy/APIController.java

package com.example.SpringBootDeploy;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class APIController {

    private final static Logger log = LoggerFactory.getLogger(APIController.class);

    @GetMapping("/api")
    public String api() {
        log.debug("debug");
        log.info("info");
        log.warn("warn");
        return "api";
    }
}

• 测试

./gradlew bootrun

curl localhost:8080/api
# "api"
# "info"
# "warn"

配置

./gradlew build

/usr/bin/java -jar /Users/kevin/Desktop/java/SpringBootDeploy/build/libs/SpringBootDeploy-0.0.1-SNAPSHOT.jar --spring.config.location=/Users/kevin/Desktop/java/SpringBootDeploy/build/libs/application.properties

• 测试

curl localhost:9000/api
# "api"
# "info"
# "warn"
