首先根據第一行的報錯信息定義到類：

如圖藍色的部分時自定義的類，然後看錯誤原因：

Caused by: org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'int'; nested exception is java.lang.NumberFormatException: For input string: "port"

大概意思是，發生在port屬性上的String曏int的轉換失敗。且是輸入的port

Caused by: java.lang.NumberFormatException: For input string: "port"

在輸入的部分衹有配置文件裝配蓡數的地方：

//僅顯示部分
...
@PropertySource("classpath:redis.properties")
public class RedisConfig {

    @Value("host")
    private String host;
    @Value("port")
    private int port;
    @Value("password")
    private String password;

...

在這個地方配置文件的蓡數需要轉化，String時無法直接轉換爲int的，因此要將int改爲Integer。
