Spring Boot框架的Java代码开发电脑监控软件
随着信息技术的迅猛发展,计算机已经成为人们日常生活和工作中不可或缺的工具。为了保障计算机的安全和有效使用,电脑监控软件变得越来越重要。本文将介绍如何使用Spring Boot框架开发一款电脑监控软件,并提供详细的Java代码示例。
环境配置
在开始编写代码之前,我们需要进行一些基础的环境配置。首先,确保你的计算机上安装了Java Development Kit (JDK)和Maven工具。接下来,创建一个新的Spring Boot项目,可以使用Spring Initializr来快速生成项目骨架。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
开发监控模块
获取系统信息
首先,我们编写一个服务类,用于获取计算机的系统信息,如CPU使用率、内存使用情况等。
import java.lang.management.ManagementFactory;
import java.lang.management.OperatingSystemMXBean;
@Service
public class SystemInfoService {
public double getCpuLoad() {
OperatingSystemMXBean osBean = ManagementFactory.getOperatingSystemMXBean();
return osBean.getSystemLoadAverage();
}
public long getFreeMemory() {
Runtime runtime = Runtime.getRuntime();
return runtime.freeMemory();
}
public long getTotalMemory() {
Runtime runtime = Runtime.getRuntime();
return runtime.totalMemory();
}
}
数据存储
为了存储监控到的数据,我们需要创建一个实体类和对应的存储库。
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class SystemInfo {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private double cpuLoad;
private long freeMemory;
private long totalMemory;
// getters and setters
}
import org.springframework.data.jpa.repository.JpaRepository;
public interface SystemInfoRepository extends JpaRepository<SystemInfo, Long> {
}
定时任务
我们需要设置一个定时任务,定时获取系统信息并存储到数据库中。
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class SystemInfoScheduler {
@Autowired
private SystemInfoService systemInfoService;
@Autowired
private SystemInfoRepository systemInfoRepository;
@Scheduled(fixedRate = 5000)
public void collectSystemInfo() {
double cpuLoad = systemInfoService.getCpuLoad();
long freeMemory = systemInfoService.getFreeMemory();
long totalMemory = systemInfoService.getTotalMemory();
SystemInfo systemInfo = new SystemInfo();
systemInfo.setCpuLoad(cpuLoad);
systemInfo.setFreeMemory(freeMemory);
systemInfo.setTotalMemory(totalMemory);
systemInfoRepository.save(systemInfo);
}
}
数据展示
为了方便查看监控到的数据,我们可以使用Thymeleaf模板引擎来创建一个简单的Web页面。
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.List;
@Controller
public class SystemInfoController {
@Autowired
private SystemInfoRepository systemInfoRepository;
@GetMapping("/systeminfo")
public String getSystemInfo(Model model) {
List<SystemInfo> systemInfos = systemInfoRepository.findAll();
model.addAttribute("systemInfos", systemInfos);
return "systeminfo";
}
}
在src/main/resources/templates目录下创建systeminfo.html文件:
<!DOCTYPE html>
<html xmlns:th="https://www.thymeleaf.org">
<head>
<title>System Info</title>
</head>
<body>
<h1>System Information</h1>
<table>
<tr>
<th>ID</th>
<th>CPU Load</th>
<th>Free Memory</th>
<th>Total Memory</th>
</tr>
<tr th:each="systemInfo : ${systemInfos}">
<td th:text="${systemInfo.id}"></td>
<td th:text="${systemInfo.cpuLoad}"></td>
<td th:text="${systemInfo.freeMemory}"></td>
<td th:text="${systemInfo.totalMemory}"></td>
</tr>
</table>
</body>
</html>
监控到的数据,如何自动提交到网站
为了将监控到的数据自动提交到网站,我们可以使用RestTemplate进行HTTP请求。首先,添加依赖:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
然后,在定时任务中添加代码,将数据提交到网站:
import org.springframework.web.client.RestTemplate;
import java.util.HashMap;
import java.util.Map;
@Component
public class SystemInfoScheduler {
@Autowired
private SystemInfoService systemInfoService;
@Autowired
private SystemInfoRepository systemInfoRepository;
@Scheduled(fixedRate = 5000)
public void collectSystemInfo() {
double cpuLoad = systemInfoService.getCpuLoad();
long freeMemory = systemInfoService.getFreeMemory();
long totalMemory = systemInfoService.getTotalMemory();
SystemInfo systemInfo = new SystemInfo();
systemInfo.setCpuLoad(cpuLoad);
systemInfo.setFreeMemory(freeMemory);
systemInfo.setTotalMemory(totalMemory);
systemInfoRepository.save(systemInfo);
// 提交数据到网站
RestTemplate restTemplate = new RestTemplate();
String url = "https://www.vipshare.com";
Map<String, Object> data = new HashMap<>();
data.put("cpuLoad", cpuLoad);
data.put("freeMemory", freeMemory);
data.put("totalMemory", totalMemory);
restTemplate.postForObject(url, data, String.class);
}
}
通过以上步骤,我们成功地使用Spring Boot框架开发了一款简单的电脑监控软件。该软件能够定时获取计算机的系统信息,并将数据存储在本地数据库中,同时也能够自动将监控到的数据提交到指定网站。希望本文对你在实际开发过程中有所帮助。
