Idea新建Springboot项目

【特别注意】

idea运行时，文件会在项目目录下，有file和log文件夹。打包时，会去掉依赖，因此运行时，需要指定环境变量。
启动.bat文件如下

java -classpath "D:/Users/windows/jdk17/springjars/*;web-root.jar" com.lkl.web.root.MyApp
@pause

由于后面pom.xml指定了依赖输出目录为 【D:\Users\windows\jdk17\springjars】 因此这里写同样的地址

1、创建项目，注意左侧模块的选择

创建项目

2、配置maven和maven仓库

maven设置

setting.xml文件如下

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <pluginGroups>
    </pluginGroups>
    <proxies>
    </proxies>
    <servers>
        <server>
            <id>nexus-releases</id>

            <name>The code storage of lkl</name>
            <url>http://www.wxylkl.cn:880/content/repositories/public/</url>
        </mirror>
        
        <mirror>
            <id>alimaven</id>
            <mirrorOf>alimaven</mirrorOf>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
        </mirror>
        <mirror>
            <id>maven2</id>

        </mirror>
    </mirrors>
    <profiles>
    </profiles>
</settings>

3、打开项目的pom.xml文件配置这个

<?xml version="1.0" encoding="UTF-8"?>

            <url>http://www.wxylkl.cn:880/content/repositories/public</url>
        </repository>
    </repositories>
</project>

4、配置项目src/main/resources/application.properties文件

spring.web.resources.static-locations=file:${user.dir}/file/,classpath:/static/,classpath:/public/
spring.mvc.static-path-pattern=/file/**
spring.application.name=web-root
server.port=80
# once size:10MB
spring.servlet.multipart.max-file-size=1000MB
# once total size:100MB
spring.servlet.multipart.max-request-size=1500MB
# enable file upload
spring.servlet.multipart.enabled=true
# 
spring.mvc.throw-exception-if-no-handler-found=true
# 
server.error.whitelabel.enabled=false
# 
server.error.path=/error

5、配置项目启动入口的类

import com.lkl.web.base.BaseApp;
import com.lkl.web.base.utils.Log;
import com.lkl.web.base.utils.MainExecutor;
import com.lkl.web.base.utils.MyDateBean;
import com.lkl.web.base.utils.listener.OnAppInitCall;
import jakarta.annotation.PreDestroy;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.event.ApplicationReadyEvent;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.event.EventListener;

@SpringBootApplication
@ComponentScan(basePackages = {"com.lkl.web.luck", "com.lkl.web.base.api", "com.lkl.web.root.api.config"})
public class App {
    public static void main(String[] args) {
        BaseApp.init(SpringApplication.run(App.class, args), new OnAppInitCall() {
            @Override
            public void onBaseInitSuccess() {
                MainExecutor.get().execute(() -> {
                    try {
                        Thread.sleep(3000);
                        MyServer.getInstance().start(BaseApp.name);
                        //0离线，1在线（0未知，1运动，2静止）
                        new PositionDao().resetDeviceState();
                    } catch (Exception e) {
                        Log.e(e);
                    }
                });
            }

            @Override
            public int configPort() {
                return 0;
            }

            @Override
            public void onSecondExecute(MyDateBean dateBean) {
              //每秒回调
            }

            @Override
            public void onDayStartExecute(MyDateBean dateBean) {
              //每天0点0分0秒回调
            }

            @Override
            public void onRequestUrlCall(jakarta.servlet.http.HttpServletRequest request) {
                if ("OPTIONS".equals(request.getMethod())) {
                    //忽略OPTIONS方法，不做api记录
                    return;
                }
            }
        });
    }

    @EventListener(ApplicationReadyEvent.class)
    public void onApplicationReady() {
        System.out.println("应用已就绪，可处理请求！");
        BaseApp.onApplicationCreated();
    }

    @PreDestroy
    public void onShutdown() {
        System.out.println("应用正在关闭...");
        // 执行资源释放逻辑
        BaseApp.onApplicationDestroyed();
    }
}

5、写一个根API（也叫控制器）


import com.lkl.web.base.BaseApp;
import jakarta.servlet.http.HttpServletResponse;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.io.IOException;

@RestController
public class RootApi {
    @GetMapping("/")
    public void root(HttpServletResponse response) throws IOException {
        // 重定向到某个项目
        response.sendRedirect(BaseApp.ip + ":81");
    }
}

然后写一个测试控制器

@RestController
public class TestApi {
    @GetMapping("/api/t1")
    public String t1() {
        return "接口测试成功--->" + System.currentTimeMillis();
    }

    @GetMapping("/api/t2")
    public String t2() {
        throw new MyException(400, "这里发生一些错误");

    }

    @POST("/api/t3")
    public CallResult<Void> t3() {
        return CallResult.ok("请求成功");
    }
}
