三、代码规范配置

3.1 文件头和作者信息

配置入口：依次打开 File -> Settings -> Editor -> File and Code Templates。

Class

/*** Copyright (C) 2020-${YEAR}, Glodon Digital Supplier & Purchaser BU.* * All Rights Reserved.*/
#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")/*** 类描述** @author 名字* @date ${YEAR}-${MONTH}-${DAY} ${HOUR}:${MINUTE}:${SECOND}*/
public class ${NAME} 
{}

Interface

/*** Copyright (C) 2020-${YEAR}, Glodon Digital Supplier & Purchaser BU.* * All Rights Reserved.*/
#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")/*** 类描述** @author 名字* @date ${YEAR}-${MONTH}-${DAY} ${HOUR}:${MINUTE}:${SECOND}*/ 
public interface ${NAME}
{}

Enum

/*** Copyright (C) 2020-${YEAR}, Glodon Digital Supplier & Purchaser BU.* * All Rights Reserved.*/
#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")/*** 类描述** @author 名字* @date ${YEAR}-${MONTH}-${DAY} ${HOUR}:${MINUTE}:${SECOND}*/
public enum ${NAME}
{}

AnnotationType

/*** Copyright (C) 2020-${YEAR}, Glodon Digital Supplier & Purchaser BU.* * All Rights Reserved.*/
#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")/*** 类描述** @author 名字* @date ${YEAR}-${MONTH}-${DAY} ${HOUR}:${MINUTE}:${SECOND}*/
public @interface ${NAME} 
{}

3.2 统一缩进

咱们后台的Java项目统一要求：使用tab缩进。接来下我们来看一下怎么在IDEA中设置使用tab缩进。

设置入口: Settings -> Editor -> Code style -> Java。

3.3 编码规范

要求	限制
单个方法最大行数	不大于80行
单个方法最大列数	不大于120列
单个类最大行数	不大于1500行
