FileInputStream serviceAccount = new FileInputStream(googleJson.getInputStream()); ``` #### 正确写法 ```java @Value(value = "classpath:rr-hitube-firebase-adminsdk-ivopy-0743e9a8b3.json") private Resource googleJson; ----- FileInputStream serviceAccount = new FileInputStream(googleJson.getInputStream()); ```
