        System.setProperty("java.security.auth.login.config",
                loader.getResource("").getPath() + File.separator + "com/shenyue/collectionpro/kafka_client_jaas.conf");
    }

文件内容：

怎么解决的呢？

✎﹏₯㎕ _ 慢走i -> 無名 2年前

把权限文件放外面把路径写死就行了

你需要把kafka_client_jaas.conf 放在你启动项目的Resource目录下，通过classpath路径直接获取。
原因是你打成jar包之后，启动项目会把所有的jar和class文件加载了启动项目，你使用getResources他不会去找你所对应的jar包里面的class文件获取配kafka_client_jaas.conf ，而是直接通过项目直接获取kafka_client_jaas.conf，则此此路径不对则找不到相对应的文件。

是放在Resource下的

半兽人 -> ✎﹏₯㎕ _ 慢走i 2年前

kafka_client_jaas.conf是在启动类的Resource中吗？

✎﹏₯㎕ _ 慢走i -> 半兽人 2年前

是的

你如果是使用FileInputStream去读取文件，它是绝对路径获取文件，

java.io.FileNotFoundException: file:/xxxx/target/docker-demo.jar!/BOOT-INF/classes!/com/shenyue/collectionpro/kafka_client_jaas.conf (No such file or directory)

使用Jar的时候启动运行，系统不是认这个路径的。

你可以读取文件的时候使用

ClassPathResource classPathResource = new ClassPathResource("com/shenyue/collectionpro/kafka_client_jaas.conf");

他是直接去classes目录中获取资源读取的。

他不是读的文件而是读的配置

先前发布贴出来的代码是如何获取配置文件的路径。
能否将读取kafka_client_jaas.conf配置文件的代码贴出来看下吗？

我把它写死了文件放出来了

KafkaClient {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="admin"
    password="Zjshenyue2021";
};
