Java 8 : Reading a file into a String

Question

我在 Controller 的同一个包中有一个json文件，我尝试读取该文件并将其转换为String

new String(Files.readAllBytes(Paths.get("CustomerOrganization.json")));

但是我得到一个错误:

java.nio.file.NoSuchFileException: CustomerOrganization.json

Answer 1

主要使用与您相同的方法:

new String(Files.readAllBytes(Paths.get(CustomerControllerIT.class.getResource("CustomerOrganization.json").toURI())));

但是，如果您需要它在 JAR 中工作，则需要改为这样做:

InputStream inputStream = CustomerControllerIT.class.getResourceAsStream("CustomerOrganization.json");
