CRM第六天：客户拜访管理，权限配置，验证码实现
目录
1.CRM客户关系管理系统：客户拜访记录
1.1需求概述
一个系统的用户（公司业务员），业务员需要对客户进行拜访，对拜访的过程进行记录。业务员（用户）和客户（客户）之间关系（需要具体业务具体分析：一对多—公司产品比较单一，只允许一个业务员对应多个客户。多对多—大公司有不同的产品，不同产品下有不同业务员都可以接触到同一个客户，一个客户可以对应多个业务员）。大部分情况创建成多对多。
- 多对多建表原则：
- 创建中间表，中间表中至少两个字段分别作为外键指向多对多双方的主键。
1.2准备工作
1.2.1创建表
CREATE TABLE `sale_visit` (
`visit_id` varchar(32) NOT NULL,
`visit_cust_id` bigint(32) DEFAULT NULL COMMENT '客户id',
`visit_user_id` bigint(32) DEFAULT NULL COMMENT '负责人id',
`visit_time` datetime DEFAULT NULL COMMENT '拜访时间',
`visit_addr` varchar(128) DEFAULT NULL COMMENT '拜访地点',
`visit_detail` varchar(256) DEFAULT NULL COMMENT '拜访详情',
`visit_nexttime` date DEFAULT NULL COMMENT '下次拜访时间',
PRIMARY KEY (`visit_id`),
KEY `FK_sale_visit_cust_id` (`visit_cust_id`),
KEY `FK_sale_visit_user_id` (`visit_user_id`),
CONSTRAINT `FK_sale_visit_cust_id` FOREIGN KEY (`visit_cust_id`) REFERENCES `cst_customer` (`cust_id`) ON DELETE NO ACTION ON UPDATE NO ACTION,
CONSTRAINT `FK_sale_visit_user_id` FOREIGN KEY (`visit_user_id`) REFERENCES `sys_user` (`user_id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
1.2.2创建实体和映射
实体：
package com.albertyy.crm.entity;
import java.sql.Date;
import java.sql.Timestamp;
/**

}配置文件：
<!-- 验证码action -->
<action name="SecurityCodeImageAction" class="com.albertyy.crm.web.action.SecurityCodeImageAction">
<result name="success" type="stream">
<param name="contentType">image/jpeg</param>
<param name="inputName">imageStream</param>
<param name="bufferSize">2048</param>
</result>
</action>
3.3编写页面
Html：
<a href="###"><img id="Verify" src="${pageContext.request.contextPath}/SecurityCodeImageAction.action" alt="看不清换一张" width="80" height="40"></a>Js:
<script type="text/javascript">
window.onload=function(){
var verifyObj = document.getElementById("Verify");
verifyObj.onclick=function(){
this.src="SecurityCodeImageAction.action?timestamp="+new Date().getTime();
};
}
</script>
本项目基本的功能已经实现，由于只是练手，后边的小功能不在实现，如有需要可以自己实现。
