一直对一些问题没有去深的研究,有人说Intellij好,有人说MyEclipse好,有人说Eclipse好,其实萝卜青菜各有所爱,只是看大家使用的习惯或者说公司用什么,你不能左右的时候,请去适合周围的环境,当我们说建立一个类的时候,最后去重写其toString方法,但是我们是否考虑过生成自己喜欢的风格呢? 下面我就来介绍一下使用Eclipse定制生成toString模版
Eclipse官方文档
这里我借鉴了 https://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Freference%2Fref-dialog-tostring.htm 文档说明,稍后再来回顾
Eclipse定制toString模版图解
-
1.点击toString方法
image -
2.点击编辑按钮
image -
3.点击New按钮设计新的规则
imageimage -
4.定制生成Json格式的规则策略
{"className":"{object.getClassName}","{member.name()}":"{member.value}","{otherMembers}"}image点击OK完成,之后需要在toString的页面设置
-
5.最后一步设置
image -
6.生成效果如下
@Override public String toString() { StringBuilder builder = new StringBuilder(); builder.append("{\""); if (this.role_id != null) { builder.append("role_id\":\""); builder.append(this.role_id); builder.append("\",\""); } if (this.role_name != null) { builder.append("role_name\":\""); builder.append(this.role_name); builder.append("\",\""); } if (this.role_key != null) { builder.append("role_key\":\""); builder.append(this.role_key); builder.append("\",\""); } if (this.status != null) { builder.append("status\":\""); builder.append(this.status); } builder.append("\"}"); return builder.toString(); }
模版属性简单说明
| ${object.className} | inserts the class name as a simple String |
|---|---|
| ${object.getClassName} | inserts a call to this.getClass.getName()
|
| ${object.superToString} | inserts a call to super.toString()
|
| ${object.hashCode} | inserts a call to this.hashCode()
|
| ${object.identityHashCode} | inserts a call to System.identityHashCode(this)
|
| ${member.name} | inserts the first member's name |
| ${member.name()} | inserts the first member's name followed by parenthesis in case of methods |
| ${member.value} | inserts the first member's value |
| ${otherMembers} | inserts the remaining members. For each member, the template fragment between the first and the last ${member.*} variable is evaluated and appended to the result. The characters between the last ${member.*} and ${otherMembers} define the separator that is inserted between members (${otherMembers} must stand after the last ${member.*} variable). |
