# Springboot 读取 resources 下文件 ## 1. 使用org.springframework.core.io.ClassPathResource ```java @Test public void testReadFile() throws IOException { // ClassPathResource classPathResource = new ClassPathResource("resource.properties"); Resource resource = new ClassPathResource("resource.properties"); InputStream is = resource.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String data = null; while((data = br.readLine()) != null) { System.out.println(data); } br.close(); isr.close(); is.close(); } ``` ## 2. Spring注解，使用org.springframework.core.io.ResourceLoader ```java package com.tsinkai.ettp; ​ import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; ​ import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.core.io.Resource; import org.springframework.core.io.ResourceLoader; import org.springframework.test.context.junit4.SpringRunner; ​ @RunWith(SpringRunner.class) @SpringBootTest public class Test { ​ @Autowired ResourceLoader resourceLoader; @Test public void testReaderFile() throws IOException { Resource resource = resourceLoader.getResource("classpath:resource.properties"); InputStream is = resource.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String data = null; while((data = br.readLine()) != null) { System.out.println(data); } br.close(); isr.close(); is.close(); } ​ } ```
