idea2024创一个Spring Web项目springdemo1

使用maven-assembly-plugin插件打包成JAR文件

pom.xml参考如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.5.6</version></parent><groupId>com.jk</groupId><artifactId>Springdemo1</artifactId><version>0.0.1-SNAPSHOT</version><name>Springdemo1</name><description>Springdemo1</description><url/><licenses><license/></licenses><developers><developer/></developers><scm><connection/><developerConnection/><tag/><url/></scm><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin><plugin><artifactId>maven-assembly-plugin</artifactId><configuration><archive><manifest><mainClass>com.jk.springdemo1.Springdemo1Application</mainClass><!-- 这里要输入mainClass的地址 --></manifest></archive><descriptorRefs><descriptorRef>jar-with-dependencies</descriptorRef></descriptorRefs></configuration><executions><execution><id>make-assembly</id> <!-- this is used for inheritance merges --><phase>package</phase> <!-- bind to the packaging phase --><goals><goal>single</goal></goals></execution></executions></plugin></plugins></build></project>

com.jk.springdemo1/controller/hellocontroller.java

package com.jk.springdemo1.Controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;@RestController
public class hellocontroller{@RequestMapping(value="/",method = RequestMethod.GET)public String index(@RequestParam(value="name",required = false,defaultValue = "lihua") String name){System.out.println("hello");return "HelloWorld,"+name;}
}

idea终端输入mvn package开始打包

PS：可以把生成的jar文件放入lib目录下，右键->add as library，之后再项目其他位置import就可以用了。

下面把Springdemo1-0.0.1-SNAPSHOT.jar拖进kali虚拟机

idea添加Remote JVM Debug，Host填虚拟机ip

在这里插入图片描述

kali

java -version
sudo su
update-alternatives --config java     #切换jdk版本到jdk11
java -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:9988 -jar Springdemo1*
