springboot 应用注意事项

mysql安装 docker-compose.yml内容

version: '3'
 
services:
    mysql-db:
        container_name: mysql5.7
        image: mysql:5.7
 
        ports:
          - "13306:3306"
        environment:
            MYSQL_ROOT_PASSWORD: "root"
			- TZ=Asia/Shanghai
        command:
          --wait_timeout=31536000
          --interactive_timeout=31536000
          --max_connections=1000
        volumes:
          - "./mysql/data: /var/lib/mysql"
          - "./mysql/config: /etc/mysql/conf.d"

maven 换源 setting.xml

      
          
            alimaven  
            aliyun maven  
            http://maven.aliyun.com/nexus/content/groups/public/  
            central          
          
      

排除自动配置bean @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})

pom.xml 配置druid和Hibernate验证

自动生成实体类


响应基类

import lombok.Data;


@Data
public class BaseResponse {

    private int code;

    private T data;

    private String message;

    public BaseResponse(int code, T data, String message) {
        this.code = code;
        this.data = data;
        this.message = message;
    }
}

响应工具类

public class ResultUtils {

    
    public static  BaseResponse success(T data) {
        return new BaseResponse<>(0, data, "ok");
    }

    
    public static  BaseResponse error(int code, String errorMessage) {
        return new BaseResponse<>(code, null, errorMessage);
    }
}
