首先根据第一行的错误消息定义类：

在这里插入图片描述
如图蓝色的部分时自定义的类，然后看错误原因：

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"

这可能意味着端口属性上发生的从 String 到 int 的转换失败。这是输入端口

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

输入部分，只有配置文件组装参数：

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

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

...

在这里插入图片描述

这里需要转换配置文件的参数。 String不能直接转换为int，所以int必须改为Integer。
