一直對(duì)一些問題沒有去深的研究,有人說Intellij好,有人說MyEclipse好,有人說Eclipse好,其實(shí)蘿卜青菜各有所愛,只是看大家使用的習(xí)慣或者說公司用什么,你不能左右的時(shí)候,請(qǐng)去適合周圍的環(huán)境,當(dāng)我們說建立一個(gè)類的時(shí)候,最后去重寫其toString方法,但是我們是否考慮過生成自己喜歡的風(fēng)格呢? 下面我就來介紹一下使用Eclipse定制生成toString模版

Eclipse官方文檔

這里我借鑒了 Eclipse官方文檔 文檔說明,稍后再來回顧

Eclipse定制toString模版圖解

• 1.點(diǎn)擊toString方法

• 2.點(diǎn)擊編輯按鈕

• 3.點(diǎn)擊New按鈕設(shè)計(jì)新的規(guī)則

• 4.定制生成Json格式的規(guī)則策略

  {"className":"{object.getClassName}","{member.name()}":"{member.value}","{otherMembers}"} 復(fù)制代碼

  點(diǎn)擊OK完成,之后需要在toString的頁(yè)面設(shè)置

• 5.最后一步設(shè)置

• 6.生成效果如下

  @Overridepublic 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();} 復(fù)制代碼

模版屬性簡(jiǎn)單說明

${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.*} and {otherMembers} must stand after the last ${member.*} variable).
