Java定义获取类属性名方法减少hardcode代码

本产品中调用存储过程,前端属性绑定到只需要知道Model对象的属性名称。引用时直接使用属性名会导致程序中出现很多harcode代码。可以为每个Model类定义一个ModelField类，ModelField类定义了一些返回Model类属性名称的方法，这样可以防止hardcode代码，对以后的维护也很有帮助。本文将介绍如何定义和使用ModelField,包括”定义所有ModelField类的父类“、”具体的ModelField继承了BaseModelField“、”使用ModelField“。

1、定义所有ModelField类的父类。

BaseModelField是所有ModelField类的父类，定义了一些获取公共属性的方法：

  1. package com.bx.erp.model;
  2.  
  3. public class BaseModelField {
  4. 	protected String FIELD_NAME_ID;
  5.  
  6. 	public String getFIELD_NAME_ID() {
  7. 		return "ID";
  8. 	}
  9.  
  10. 	protected String FIELD_NAME_listSlave1;
  11.  
  12. 	public String getFIELD_NAME_listSlave1() {
  13. 		return "listSlave1";
  14. 	}
  15. 	
  16. 	protected String FIELD_NAME_listSlave2;
  17. 	
  18. 	public String getFIELD_NAME_listSlave2() {
  19. 		return "listSlave2";
  20. 	}
  21.  
  22. 	protected String FIELD_NAME_listSlave3;

  55. 		return "iOrderBy";
  56. 	}
  57.  
  58. 	protected String FIELD_NAME_isASC;
  59.  
  60. 	public String getFIELD_NAME_isASC() {
  61. 		return "isASC";
  62. 	}
  63.  
  64. 	protected String FIELD_NAME_ErrorMessage;
  65.

  86. 	}
  87.  
  88. 	protected String FIELD_NAME_queryKeyword;
  89.  
  90. 	public String getFIELD_NAME_queryKeyword() {
  91. 		return "queryKeyword";
  92. 	}
  93.  
  94. 	protected String FIELD_NAME_fieldToCheckUnique;
  95.  
  96. 	public String getFIELD_NAME_fieldToCheckUnique() {
  97. 		return "fieldToCheckUnique";
  98. 	}
  99.  
  100. 	protected String FIELD_NAME_date1;
  101.  
  102. 	public String getFIELD_NAME_date1() {
  103. 		return "date1";
  104. 	}
  105.  
  106. 	protected String FIELD_NAME_date2;
  107.  
  108. 	public String getFIELD_NAME_date2() {
  109. 		return "date2";

  112. 	protected String FIELD_NAME_iPageIndex;
  113.  
  114. 	public String getFIELD_NAME_iPageIndex() {
  115. 		return "iPageIndex";
  116. 	}
  117.  
  118. 	protected String FIELD_NAME_iPageSize;
  119.  
  120. 	public String getFIELD_NAME_iPageSize() {
  121. 		return "iPageSize";
  122. 	}
  123.  
  124. 	protected String FIELD_NAME_uniqueField;
  125.  
  126. 	public String getFIELD_NAME_uniqueField() {
  127. 		return "uniqueField";

  158. 	}
  159.  
  160. }

2、具体的ModelField继承了BaseModelField。

例如：StaffField：

查看代码 
  1. public class StaffField extends BaseAuthenticationModelField {
  2. 	protected String FIELD_NAME_involvedResigned;
  3.  
  4. 	public String getFIELD_NAME_involvedResigned() {
  5. 		return "involvedResigned";
  6. 	}
  7.  
  8. 	protected String FIELD_NAME_forModifyPassword;

  71. 		return "openid";
  72. 	}
  73.

  78. 	}
  79.  
  80. 	protected String FIELD_NAME_ICID;
  81.  
  82. 	public String getFIELD_NAME_ICID() {
  83. 		return "ICID";
  84. 	}
  85.  
  86. 	protected String FIELD_NAME_passwordExpireDate;
  87.  
  88. 	public String getFIELD_NAME_passwordExpireDate() {
  89. 		return "passwordExpireDate";
  90. 	}
  91.  
  92. 	protected String FIELD_NAME_isFirstTimeLogin;
  93.  
  94. 	public String getFIELD_NAME_isFirstTimeLogin() {
  95. 		return "isFirstTimeLogin";
  96. 	}
  97.  
  98. 	protected String FIELD_NAME_shopID;
  99.  
  100. 	public String getFIELD_NAME_shopID() {
  101. 		return "shopID";
  102. 	}
  103.  
  104. 	protected String FIELD_NAME_departmentID;
  105.  
  106. 	public String getFIELD_NAME_departmentID() {
  107. 		return
