本文详细介绍如何在Eclipse中进行各种实用配置，包括但不限于调整控制台输出行数、设置注释模板、添加文件关联、更改字体样式及编码方式等。此外还提供了如何设置代码模板来提高开发效率的方法。

Eclipse Console 加大显示的行数：

在 Preferences-〉Run/Debug-〉Console里边，去掉对Limit console output的选择，或者选择，设置一下buffer size的设定值

Window->preferences->Java->Code Style->Code templates. 选中Comments下的Types，edit

/**
 * @author Corleone
 * @created at ${date}${time}
 * ${tags}
 */

windows->perferences->General->Editors->File Associations

新增*.ini -> Text Editor

查看Eclipse 版本号

.eclipseproduct 中

设置字体

windows->perferences->General->Appearance->Colors and Fonts->Basic->Text Font->Edit->字体选 Courier New

Text文件编码

windows->perferences->General->Workspace 页面下的->Text file encoding->选Other：(UTF-8)

windows->Preferences->General->ContentTypes->Text->Java Properties File，设置Default encoding，utf-8

eclipse setter 返回this，确保可链式调用

Window->preferences->Java->Code Style->Code templates. 
Code 下 选中 "Setter body" template as following:

${field} = ${param};
return this;

# 结果如下，需要手动再将void 改成对应的类名
public void setMyField(String myField) {
    this.myField = myField;
    return this;
}

java 代码模版

# Window->preferences->Java->Editor->templates. 
Edit "new" template as following:

# return_list

${imp:import(java.util.ArrayList)}

${return_type} ${varName} = new ${ArrayList}<>(${});
	${cursor}
return ${varName};

# return_set
