IntelliJ IDEA新建maven项目

https://blog.csdn.net/m0_57532432/article/details/135991277

点击运行之后，多出来target目录

右击运行

也就是都可以运行，这两处

写了个Java文件，里面用package的时候，指定是目录名，从项目根目录下src/main/java下开始写路径。运行代码的时候，生成target目录下的clsses，根据上面写的代码路径生成对应的class文件

新建一个spingboot项目

package com.example.demo;

/**
 * Hello Controller
 */
@RestController
public class HelloController {

    @GetMapping("/")
    public String hello() {
        return "Hello World"
    }
}

package com.example.demo;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * Hello Controller
 */
@RestController
public class HelloController {

    @GetMapping("/")
    public String hello() {
        return "Hello World";
    }
}

导入之后还是有报错

OpenJDK 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended

上面新建项目，指定的是jar,现在指定war试试：

然后点击运行

可以访问到：

新增一个路由

package com.example.demo;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * Hello Controller
 */
@RestController
public class HelloController {

    @GetMapping("/")
    public String hello() {
        return "Hello World";
    }
    @GetMapping("/mcw")
    public String hello2() {
        return "Hello machangwei";
    }
}

重启项目，可以正常访问到

idea中把spring boot项目打成jar包

打jar包

打开项目，右击项目选中Open Module Settings进入project Structure

选中Artifacts，点击中间的加号（Project Settings->Artifacts->JAR->From modules with dependencies ）

弹出Create JAR from Modules，选择‘Main Class’，然后一路ok

点击右侧的Maven Projects，打开LIfecycle，先点击clean，再点击package，生成target文件夹（在该项目文件夹内），里面有以项目名命名加版本号的jar文件，打包完成啦

运行jar包
入jar所在的文件夹，使用java -jar命令运行jar，项目就能启动

java -jar jar包名-SNAPSHOT.jar

@@@

清理，是删除之前的target目录
