IOUtils.toString()方法

需要在pom.xml中加入:


			commons-io
			commons-io
			2.3
		

在maven->update一下
在class 文件中导入import org.apache.commons.io.IOUtils;
之后使用IOUtils.toString()方法,但是有异常,需要捕获
完整代码:

package com.wisely.highlight_spring4.ch3.aware;

import org.springframework.beans.factory.BeanNameAware;
import org.springframework.context.ResourceLoaderAware;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.apache.commons.io.IOUtils;

import java.io.IOException;

public class AwareService implements BeanNameAware,ResourceLoaderAware{
    private String beanName;
    private ResourceLoader loader;


    @Override
    public void setBeanName(String name) {
        this.beanName = name;
    }

    @Override
    public void setResourceLoader(ResourceLoader resourceLoader) {
        this.loader = resourceLoader;
    }
    public void outputResult(){
        System.out.println("Bean的名称为:"+beanName);
        Resource resource = loader.getResource("classpath:com/wisely/highlight_spring4/ch3/aware/text.txt");
        try{
            System.out.println("ResourceLoader加载的文件内容为:"+ IOUtils.toString(resource.getInputStream()));
        }catch (IOException e){
            e.printStackTrace();
        }

    }
    
}
