我是Spring的新手，我正在尝试实现一个简单的弹簧启动应用程序，该应用程序将解析JSON字符串并将其写入文件。
这是我的主要类的代码
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
//@SpringBootApplication
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
private static Class<Application> applicationClass = Application.class;
}
休息控制器的定义在
下面package com.example;
import java.io.*;
import javax.servlet.http.HttpServletRequest;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class Controller {
@RequestMapping(path="/api",consumes=MediaType.APPLICATION_JSON_VALUE)
public String insertData(@RequestBody String rawJsonData,HttpServletRequest request) throws ParseException, IOException{
JSONParser jparser=new JSONParser();
Object jsonObj=jparser.parse(rawJsonData);
JSONObject jObject=(JSONObject)jsonObj;
FileWriter filewriter=new FileWriter(new File("C:\Users\Desktop\Aayushi.txt"));
filewriter.write(jObject.toJSONString());
return rawJsonData;
}
}
updated pom.xml文件如下定义

如果我以运行AS-> maven构建运行此代码，那么我会收到以下错误，我不确定为什么这些错误会出现。
