Jeesite七个文件作用解释

Jeesite的七个文件：

Entity.java
EntityDao.java
EntityService.java
EntityController.java
EntityDao.xml
entityList.jsp
entityForm.jsp

七个文件的作用：

1. Entity.java：
定义使用到的属性名，以及set和get方法来对属性进行设置和获取

public class Entity extends DataEntity<Entity > {private static final long serialVersionUID = 1L;//控制版本一致private String major;           // 专业private String masterName;      // 硕士名//有参和无参构造器public Entity () {super();}public Entity (String id){super(id);}//属性的get和set方法，可以由eclipse的source--Generate Getters and Setters自动生成public String getMajor() {return major;}public void setMajor(String major) {this.major = major;}public String getMasterName() {return masterName;}public void setMasterName(String masterName) {this.masterName = masterName;}
}

2. EntityDao.java：
1. 接口，定义使用到的方法名，包括get/findList/findAllList/update/insert/…等方法名
2. 和EntityDao.xml连接，调用sql语句

public interface DistributeDao extends CrudDao<Distribute> {//其父类定义有相关方法名
}

3. EntityService.java：
用来具体实现EntityDao.java中定义的方法

@Service
@Transactional(readOnly = true)//设置为只读
public class EntityService extends CrudService<EntityDao, Entity> {public Entity get(String id) {return super.get(id);}public List<Entity> findList(Entity entity) {return super.findList(entity);}public Page<Entity> findPage(Page<Entity> page, Entity entity) {return super.findPage(page, entity);}@Transactional(readOnly = false)public void save(Entity entity) {super.save(entity);}@Transactional(readOnly = false)public void delete(Entity entity) {super.delete(entity);}
}

4. EntityController.java：
1. 定义了一些自定义方法，可以被jsp文件调用。
2. 该文件如果需要使用service的方法，可以创建service对象后调用所需要的方法

@Controller
@RequestMapping(value = "${adminPath}/gsmis/distribute")
//请求映射，value为该文件的地址。
public class DistributeController extends BaseController {@Autowired//自动注入private DistributeService distributeService;@ModelAttribute//模型属性：无论调用什么方法都会优先执行该注解的方法public Distribute get(@RequestParam(required=false) String id) {Distribute entity = null;if (StringUtils.isNotBlank(id)){entity = distributeService.get(id);}if (entity == null){entity = new Distribute();}return entity;}//验证是否有值传过来@RequiresPermissions("gsmis:distribute:view")//权限声明：view查看，edit编辑@RequestMapping(value = {"list", ""})//jsp文件执行的方法名public String list(Distribute distribute, HttpServletRequest request, HttpServletResponse response, Model model) {Page<Distribute> page = distributeService.findPage(new Page<Distribute>(request, response), distribute); //考虑分页model.addAttribute("page", page);//返回到jsp的值return "imd/gsmis/distributeList";//返回jsp文件}@RequiresPermissions("gsmis:distribute:view")@RequestMapping(value = "form")public String form(Distribute distribute, Model model) {model.addAttribute("distribute", distribute);return "imd/gsmis/distributeForm";}

5. EntityDao.xml：
调用数据库的·sql语句，负责对数据库的操作

<?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="cn.edu.ccnu.imd.gsmis.dao.DistributeDao"><!--对多个属性批量操作--><sql id="distributeColumns">a.id AS "id",a.major AS "major",a.masterName AS "masterName",a.topic AS "topic",a.studentID AS "studentID",a.keywords AS "keywords",a.status AS "status",a.create_by AS "createBy.id",a.create_date AS "createDate",a.update_by AS "updateBy.id",a.update_date AS "updateDate",a.remarks AS "remarks",a.del_flag AS "delFlag"</sql><sql id="distributeJoins"></sql><select id="get" resultType="Distribute">SELECT <include refid="distributeColumns"/>FROM thesis a<include refid="distributeJoins"/>WHERE a.id = #{id}</select><select id="findList" resultType="Distribute">SELECT <include refid="distributeColumns"/>FROM thesis a<include refid="distributeJoins"/><where>a.del_flag = #{DEL_FLAG_NORMAL}<！--模糊查询--><if test="major != null and major != ''">AND a.major LIKE <if test="dbName == 'oracle'">'%'||#{major}||'%'</if><if test="dbName == 'mssql'">'%'+#{major}+'%'</if><if test="dbName == 'mysql'">concat('%',#{major},'%')</if></if><if test="masterName != null and masterName != ''">AND a.masterName LIKE <if test="dbName == 'oracle'">'%'||#{masterName}||'%'</if><if test="dbName == 'mssql'">'%'+#{masterName}+'%'</if><if test="dbName == 'mysql'">concat('%',#{masterName},'%')</if></if><if test="studentID != null and studentID != ''">AND a.studentID LIKE <if test="dbName == 'oracle'">'%'||#{studentID}||'%'</if><if test="dbName == 'mssql'">'%'+#{studentID}+'%'</if><if test="dbName == 'mysql'">concat('%',#{studentID},'%')</if></if></where><choose><when test="page !=null and page.orderBy != null and page.orderBy != ''">ORDER BY ${page.orderBy}</when><otherwise>ORDER BY a.update_date DESC</otherwise></choose></select>
</mapper>

6. entityList.jsp && entityForm.jsp：
jsp文件作为前台显示的页面，可以根据方法名对controller.java的方法进行调用
list：显示展示页面
form：显示提交页面

<%@ page contentType="text/html;charset=UTF-8" %>
<%@ include file="/WEB-INF/views/include/taglib.jsp"%>
<html>
<head><title>论文分配管理</title><meta name="decorator" content="default"/><script type="text/javascript">$(document).ready(function() {/*  $("#distribute").click(function(){<a href="${ctx}/gsmis/distribute/form?id=${distribute.id}">分配</a>});*/       });function page(n,s){$("#pageNo").val(n);$("#pageSize").val(s);$("#searchForm").submit();return false;}function selectall(){if($('input[name="thesisId"]').get(0).checked){$('input[name="thesisId"]').attr("checked",false); }else{$('input[name="thesisId"]').attr("checked",true); /*$("input[name='documentId']").each(  function(){if($(this).val() != "undefined"){documentIds += $(this).val() + ","}})  */ }}</script>
</head>
