其中需要在server和schedule的启动类上添加@ComponentScan注解。

package org.example.server;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@MapperScan("org.example.common.mapper")
@ComponentScan("org.example.common.service")
@ComponentScan("org.example.server.service")
@ComponentScan("org.example.server.controller")
@SpringBootApplication
public class ServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServerApplication.class, args);
    }
}

package org.example.schedule;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan("org.example.common.service")
@ComponentScan("org.example.schedule.proc")
public class ScheduleApplication {
    public static void main(String[] args) {
        SpringApplication.run(ScheduleApplication.class, args);
    }
}
