Maven项目中获取src/main/resources下的properties文件

public void test(){
    String value = this.readValue("/vender_type.properties","4");
}


public String readValue(String filePath, String key){
    Properties prop = new Properties();
    InputStream in = null;
    try{
        in = this.getClass().getClassLoader().getResourceAsStream(filePath);
        if(in != null){
            prop.load(new InputStreamReader(in,"UTF-8"));
        }
        return prop.getProperty(key);
    }catch(){
        log.error("读取Properties配置文件信息失败",e);
    }finally{
        if(in != null){
            try {
                in.close();
            } catch (IOException e) {
                log.error("关闭输入流失败",e);
            }
        }
