（转）编码规范系列（一）eclipse设置Code Templates
点击"Import"，导入模板codetemplates.xml文件。
codetemplates.xml内容是我们自己预先定义好的，在这里先不详细描述，我们可以看到Eclipse Code Templates界面中间Configure generated code and comments区域包含了两个菜单树：Comment、Code，如下图所示：
Comments代表注释模板，Code代表代码模板，其中每一个子菜单代表子项的模板。
我们只要点击某一个子项，就会在界面下方的Pattern区域看到该项我们所定义的模板内容和格式，如下图所示：
如上图所示，当我们点击Comments下的Files子菜单时，下面的Pattern会显示Java文件的头部注释。
下面详细列出每一个子项的模板格式：
Comments-->Files（Java文件注释）
/** * Project Name:${project_name} * File Name:${file_name} * Package Name:${package_name} * Date:${date}${time} * Copyright (c) ${year}, chenzhou1025@126.com All Rights Reserved. * */?Comments-->Types（Java类注释）/** * ClassName: ${type_name} <br/> * Function: ${todo} ADD FUNCTION. <br/> * Reason: ${todo} ADD REASON(可选). <br/> * date: ${date} ${time} <br/> * * @author ${user} * @version ${enclosing_type}${tags} * @since JDK 1.6 */?Comments-->Fields（类字段注释）/** * ${field}:${todo}(用一句话描述这个变量表示什么). * @since JDK 1.6 */?Comments-->Constructors（构造函数注释）/** * Creates a new instance of ${enclosing_type}. * * ${tags} */?Comments-->Methods（Java方法注释）/** * ${enclosing_method}:(这里用一句话描述这个方法的作用). <br/> * ${todo}(这里描述这个方法适用条件 – 可选).<br/> * ${todo}(这里描述这个方法的执行流程 – 可选).<br/> * ${todo}(这里描述这个方法的使用方法 – 可选).<br/> * ${todo}(这里描述这个方法的注意事项 – 可选).<br/> * * @author ${user} * ${tags} * @since JDK 1.6 */?Comments-->Overriding methods（重写方法注释）/** * ${todo} 简单描述该方法的实现功能（可选）. * ${see_to_overridden} */Comments-->Delegate methods（代理方法注释）/** * ${tags} * ${see_to_target} */?Comments-->Getters（Java Getter方法注释）/** * ${bare_field_name}. * * @return the ${bare_field_name} * @since JDK 1.6 */?Comments-->Setters（Java Setters方法注释）/** * ${param}. * * @param ${param} the ${bare_field_name} to set * @since JDK 1.6 */?Code-->New Java files（新建java文件代码模板）/** * Project

**/${filecomment}${package_declaration}/** * ClassName:${type_name} <br/> * Function: ${todo} ADD FUNCTION. <br/> * Reason: ${todo} ADD REASON. <br/> * Date: ${date} ${time} <br/> * @author ${user} * @version * @since JDK 1.6 * @see */${typecomment}${type_declaration}?Code-->Method body（方法体模板）// ${todo} Auto-generated method stub${body_statement}?Code-->Constructor body（构造函数模板）${body_statement}// ${todo} Auto-generated constructor stub?Code-->Getter body（字段Getter方法模板）return ${field};?Code-->Setter body（字段Setter方法模板）${field} = ${param};?Code-->Catch block body（异常catch代码块模板）?// ${todo} Auto-generated catch block${exception_var}.printStackTrace();?其中codetemplates.xml内容如下：<?xml version="1.0" encoding="UTF-8" standalone="no"?><templates><template autoinsert="false"
