JEECG开发第一个菜单显示设备列表

一、新建设备表(t_base_device)

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for t_base_device
-- ----------------------------
DROP TABLE IF EXISTS `t_base_device`;
CREATE TABLE `t_base_device` (
  `deviceid` int(10) NOT NULL,
  `devicecode` varchar(50) DEFAULT NULL,
  `devicename` varchar(50) DEFAULT NULL,
  `deviceclassno` varchar(10) DEFAULT NULL,
  `status` varchar(10) DEFAULT NULL,
  `username` varchar(50) DEFAULT NULL,
  `userdept` varchar(200) DEFAULT NULL,
  PRIMARY KEY (`deviceid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of t_base_device
-- ----------------------------
INSERT INTO `t_base_device` VALUES ('10001', 'STPC201711001', '华硕X550', '0101', '使用中', '谢红卫', '软件研发部');
INSERT INTO `t_base_device` VALUES ('10002', 'STPC201711002', '联想T440P', '0101', '库存', null, null);

二、实体类(BaseDevice.java)

package net.xhw.device.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@SuppressWarnings("serial")
@Entity
@Table(name = "t_base_device")
public class BaseDevice implements java.io.Serializable{

    private int deviceid;
    private String devicecode;
    private String devicename;
    private String deviceclassno;
    private String status;
    private String username;
    private String userdept;
    
    @Id
    @Column(name = "deviceid", length = 10)
    public int getDeviceid() {
        return deviceid;
    }
    
    @Column(name = "devicecode", length = 50)
    public String getDevicecode() {
        return devicecode;
    }
    
    @Column(name = "devicename", length = 50)
    public String getDevicename() {
        return devicename;
    }
    
    @Column(name = "deviceclassno", length = 10)
    public String getDeviceclassno() {
        return deviceclassno;
    }
    
    @Column(name = "status", length = 10)
    public String getStatus() {
        return status;
    }
    
    @Column(name = "username", length = 50)
    public String getUsername() {
        return username;
    }
    
    @Column(name = "userdept", length = 200)
    public String getUserdept() {
        return userdept;
    }    
    
    public void setDeviceid(int deviceid) {
        this.deviceid = deviceid;
    }
    
    public void setDevicecode(String devicecode) {
        this.devicecode = devicecode;
    }
    
    public void setDevicename(String devicename) {
        this.devicename = devicename;
    }
    
    public void setDeviceclassno(String deviceclassno) {
        this.deviceclassno = deviceclassno;
    }
    
    public void setStatus(String status) {
        this.status = status;
    }
    
    public void setUsername(String username) {
        this.username = username;
    }
    
    public void setUserdept(String userdept) {
        this.userdept = userdept;
    }    
    
}

三、action控制类(DeviceController.java)

package net.xhw.device.ctrl;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.jeecgframework.core.common.controller.BaseController;
import org.jeecgframework.core.common.hibernate.qbc.CriteriaQuery;
import org.jeecgframework.core.common.model.json.DataGrid;
import org.jeecgframework.tag.core.easyui.TagUtil;
import org.jeecgframework.web.system.service.SystemService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import net.xhw.device.entity.BaseDevice;


@Controller
@RequestMapping("/deviceController")
public class DeviceController extends BaseController {
    
    private SystemService systemService;
    
    @Autowired
    public void setSystemService(SystemService systemService) {
        this.systemService = systemService;
    }

    @RequestMapping(params = "deviceList")
    public ModelAndView deviceList(HttpServletRequest request) {
        return new ModelAndView("device/deviceList");
    }
    
    @RequestMapping(params = "datagrid")
    public void datagrid(BaseDevice basedevice, HttpServletRequest request, HttpServletResponse response, DataGrid dataGrid) {        
        CriteriaQuery cq = new CriteriaQuery(BaseDevice.class, dataGrid);
        this.systemService.getDataGridReturn(cq, true);
        TagUtil.datagrid(response, dataGrid);
    }
    
}

四、页面文件(deviceList.jsp)

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@include file="/context/mytags.jsp"%>
<t:base type="jquery,easyui,tools,DatePicker"></t:base>

<t:datagrid name="deviceList" title="设备信息列表" actionUrl="deviceController.do?datagrid" 
    fit="true" fitColumns="true" idField="deviceid" queryMode="group">
    <t:dgCol title="设备ID" field="deviceid" hidden="true"></t:dgCol>
    <t:dgCol title="设备编码" field="devicecode" query="false" width="100"></t:dgCol>
    <t:dgCol title="设备名称" field="devicename" query="false" width="100"></t:dgCol>
    <t:dgCol title="状态" field="status" query="false" width="100"></t:dgCol>
    <t:dgCol title="使用人" field="username" query="false" width="100"></t:dgCol>
</t:datagrid>

五、修改配置文件

　　1、修改spring-mvc.xml，添加扫描控制类包　　　　

<context:component-scan base-package="org.jeecgframework.web.*,com.jeecg.*,net.xhw.*">
　　<context:exclude-filter type="annotation"
   　　expression="org.springframework.stereotype.Service" />
</context:component-scan>

　　2、修改spring-mvc-hibernate.xml，添加注解方式配置

<!-- 注解方式配置 -->
<property name="packagesToScan">
　　<list>
   　　<value>org.jeecgframework.web.system.pojo.*</value>
   　　<value>org.jeecgframework.web.test.entity.*</value>
　　　　<value>org.jeecgframework.web.autoform.*</value>
　　　　<value>org.jeecgframework.web.cgform.entity.*</value>
　　　　<value>org.jeecgframework.web.cgreport.entity.*</value>
　　　　<value>org.jeecgframework.web.cgdynamgraph.entity.*</value>
　　　　<value>org.jeecgframework.web.graphreport.entity.*</value>
　　　　<value>org.jeecgframework.web.system.sms.*</value>
　　　　<value>com.jeecg.*</value>
　　　　<value>net.xhw.*</value>
   </list>
</property>

六、菜单配置及结果
