班级字段扩展方案

[songhuiqing88]

班级基础信息字段扩展

• 班级组件（gtiles-components-gtclasses）

数据库

在用户主表中增加要扩展的字段，例如：增加活动类型、是否记录学时，SQL如下。

ALTER TABLE `gt_class_basic`
ADD COLUMN `ACTIVITY_STATE`  tinyint(4) NULL,
ADD COLUMN `IS_RECORD_SCORE`  tinyint(4) NULL;

代码扩展

dao扩展

1. 覆盖org.gtiles.components.gtclasses.classbasic.extension.dao.IClassBasicInfoExtensionDao.xml。
2. 调整xml内容，增加扩展字段，代码如下。

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE mapper
   PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
   "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
   <mapper namespace="org.gtiles.components.gtclasses.classbasic.extension.dao.IClassBasicInfoExtensionDao">
   <!-- 班级查询结果 班级字段 -->
   <resultMap type="org.gtiles.components.gtclasses.classbasic.bean.ClassBasicInfoBean" id="classBasicInfo">
   <!-- ...产品内容 -->
   <result column="ACTIVITY_STATE" jdbcType="INTEGER" property="activityState"/>
   <result column="IS_RECORD_SCORE" jdbcType="INTEGER" property="isRecordScore"/>
   </resultMap>
   <!-- 班级表字段 -->
   <sql id="queryFields">
   <!-- ...产品内容 -->
   ACTIVITY_STATE,IS_RECORD_SCORE
   </sql>
   <!-- 字段值 -->
   <sql id="fieldValue">
   <!-- ...产品内容 -->
   #{activityState},#{isRecordScore}
   </sql>
   <!-- 更新条件 -->
   <sql id="upateCommond">
   <!-- ...产品内容 -->
   <if test="activityState != null">ACTIVITY_STATE = #{activityState},</if>
   <if test="isRecordScore != null">IS_RECORD_SCORE = #{isRecordScore},</if>
   </sql>
   <!-- 查询条件 -->
   <sql id="queryCommond">
   <!-- ...产品内容 -->
   <if test="query.queryActivityState != null"> and ACTIVITY_STATE = #{query.queryActivityState}</if>
   <if test="query.queryIsRecordScore != null"> IS_RECORD_SCORE = #{query.queryIsRecordScore}</if>
   </sql>
   </mapper>

   结果对象扩展

   覆盖 org.gtiles.components.gtclasses.classbasic.bean.ClassBasicInfoBean

   public class ClassBasicInfoBean extends ClassBasicInfo {
   private Integer activityState;
   private Integer isRecordScore;
   public Integer getActivityState() {
   return activityState;
   }
   public void setActivityState(Integer activityState) {
   this.activityState = activityState;
   }
   public Integer getIsRecordScore() {
   return isRecordScore;
   }
   public void setIsRecordScore(Integer isRecordScore) {
   this.isRecordScore = isRecordScore;
   }
   public ClassBasicInfoBean() {
   super();
   }
   public ClassBasicInfoBean(ClassBasicInfoEntity classBasicInfoEntity) {
   super(classBasicInfoEntity);
   }
   }

   查询对象扩展

   覆盖 org.gtiles.components.gtclasses.classbasic.bean.ClassBasicInfoQuery

   public class ClassBasicInfoQuery extends ClassBasicInfoAbstractQuery<ClassBasicInfoBean> {
   private Integer queryActivityState;
   private Integer queryIsRecordScore;
   public Integer getQueryActivityState() {
   return queryActivityState;
   }
   public void setQueryActivityState(Integer queryActivityState) {
   this.queryActivityState = queryActivityState;
   }
   public Integer getQueryIsRecordScore() {
   return queryIsRecordScore;
   }
   public void setQueryIsRecordScore(Integer queryIsRecordScore) {
   this.queryIsRecordScore = queryIsRecordScore;
   }
   }

   界面扩展

   覆盖html，在html中增加期望新增的字段、列表字段、查询条件。
