Create 2 JavaBeans

　

Create the corresponding javabean file based on the user table and attachment table: ElecUser .java and ElecUserFile.java, the code is abbreviated

Create 2 xml

　

Because one user corresponds to multiple attachments, the user table and attachment table are one-to-many relation.

Service Design
Create Service Interface

Problem: When using the data dictionary Sometimes, data conversion is required, and there are many more SQL statements. How to optimize SQL?

Action design

　

1.Create the UserAction class

public class ElecUserAction extends BaseAction<ElecUser>{
    ElecUser elecUser=this.getModel();    
    //注入用户管理service@Resource(name=IElecUserService.SERVICE_NAME)
    IElecUserService elecUserService;    //注入数据字典service@Resource(name=IElecSystemDDLService.SERVICE_NAME)
    IElecSystemDDLService elecSystemDDLService;    /**  
    * @Name: home
    * @Description: 跳转到用户管理页面
    * @Parameters: 无
    * @Return: String：跳转到system/userIndex.jsp*/public String home(){//加载数据类型是所属单位的数据字典的集合，遍历在页面的下拉菜单中List<ElecSystemDDL> jctList = elecSystemDDLService.findSystemDDLListByKeyword("所属单位");
        request.setAttribute("jctList", jctList);//组织页面中的查询条件，查询用户表，返回List<ElecUser>List<ElecUser> userList=elecUserService.findUserlistByCondition(elecUser);
        request.setAttribute("userList", userList);return "home";
    }
}

　2.In Add 

<!-- 用户管理 --><action name="elecUserAction_*" class="elecUserAction" method="{1}">  
<result name="home">/WEB-INF/page/system/userIndex.jsp</result>        
</action>
