1. readAllBytes()
inputstream의 readAllBytes()는 JAVA9 버전부터 이용이 가능합니다.
package com.example.logbacksample;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.io.IOUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.core.io.ResourceLoader;
import org.springframework.stereotype.Component;
import java.io.InputStream;
@Slf4j
@Component
public class ResourceApplicationRunner implements ApplicationRunner {
@Autowired
ResourceLoader resourceLoader;
@Override
public void run(ApplicationArguments args) throws Exception {
InputStream inputStream = resourceLoader.getResource("classpath:res.txt").getInputStream();
byte[] bytes = inputStream.readAllBytes();
log.info("bytes : " + new String(bytes));
inputStream.close();
}
}
2. toByteArray()
package com.example.logbacksample;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.io.IOUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.core.io.ResourceLoader;
import org.springframework.stereotype.Component;
import java.io.InputStream;
@Slf4j
@Component
public class ResourceApplicationRunner implements ApplicationRunner {
@Autowired
ResourceLoader resourceLoader;
@Override
public void run(ApplicationArguments args) throws Exception {
InputStream inputStream = resourceLoader.getResource("classpath:res.txt").getInputStream();
byte[] byteArray = IOUtils.toByteArray(inputStream);
log.info("byteArray : " + new String(bytes));
