Spring Boot获取时间

运行环境新建测试类

package com.wusiyao.websockets.service;

import org.springframework.stereotype.Service;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;

@Service
public class TimeService {
public String getTime() {
System.out.println("获取时间" + new Date());

    Date d = new Date();
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd kk:mm:ss ");
    System.out.println("格式化输出：" + sdf.format(d));

    sdf.setTimeZone(TimeZone.getTimeZone("Asia/Shanghai"));
    System.out.println("Asia/Shanghai:" + sdf.format(d));

    return "格式化输出：" + sdf.format(d) + '\n' + "Asia/Shanghai:" + sdf.format(d);
}

}

TimeController:

package com.wusiyao.websockets.controller;

import com.wusiyao.websockets.service.TimeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TimeController {

@Autowired
TimeService timeService;

@RequestMapping("/time")
public String getTime(){

    return timeService.getTime();
}

}
