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
