The '.ignore' file required for the plug-in in this project has been generated. Please refer to: https://blog.csdn.net/ZZY1078689276/article/details/84952858 - The module code should be unit tested to confirm that the code is correct before pushing (PUSH) to the far end. Avoid hard-to-fix BUGS caused by conflict. ## 页面框架 Page Framework - 前端框架：layUI - layui是一款采用自身模块规范编写的前端 UI 框架，遵循原生 HTML/CSS/JS 的书写与组织形式，门槛极低，拿来即用。 - 学习教程：https://www.layui.com/doc/ - Front Page frame: layUI - Layui is a UI framework written with its own module specification, following the writing and organization of native HTML/CSS/JS, with very low thresholds for ready-to-use. - Learning tutorial: https://www.layui.com/doc/ ## 编写标准 Writing Standards ### 1、Controller层编写标准 **按照如下规则编写Controller**   模板中包含各类请求的映射方法，直接复制模板进行修改即可，模板代码如下： > @Controller > @RequestMapping(value = {"/Demo"}) > public class DemoController { >     //自动注入Service层 >     @Autowired >     private DemoService demoService; >     /** >      * 直接字符串映射样例 >      * @return >      */ >>     @RequestMapping(value = {"/StrDemo"}) >     // 使用ResponseBody可以让返回的数据变为字节流 >     @ResponseBody >     public String returnStr() { >         // 直接给前台返回一个字符串，一般用于AJAX交互。 >         return "hello,这是第一个映射"; >     } >     /** >      * 单对象获取样例 >      * @return >      */ >>     @RequestMapping(value = {"/BeanDemo"}) >     @ResponseBody >     public DemoBean returnEntify() { >         DemoBean testBean = new DemoBean(); >         testBean.setDemostr("测试实体"); >         testBean.setDemoint(12); >         // 会自动将Bean封装为JSON格式数据返回给前端 >         return testBean; >     } >     /** >      * 多对象获取样例Demo >      * @param orderAndRole >      * @return Json数据 >      * @throws Exception >      */ >>     @RequestMapping(value = { "/getMoreObjectDemo" }, method = { RequestMethod.POST }, consumes = { >      "application/json" }, produces = { "application/json" }) >     @ResponseBody >     public Object addEmpGetStu(@RequestBody VODemo orderAndRole) throws Exception { >         // 同时获取两个前端的数据，需要在VO层封装两个对象，并添加get方法，注意参数样式。 >         Order order = orderAndRole.getOrder(); >         Role role = orderAndRole.getRole(); >         order.setInfoAssessmentdate(new Date()); >         order.setInfoRemarks("这是生成的"); >         // 返回order对象的json数据。 >         JSONObject responseObj = (JSONObject) JSONObject.toJSON(order); >         return responseObj; >     } >     /** >      * service调用样例Demo >      */ >>     @RequestMapping(value = {"/ServiceDemo"}) >     @ResponseBody >     public String getUsers() { >         // 调用service中的方法。 >         List users = demoService.getUsersByExample(); >         System.out.print(users.get(0).getSex()); >         return "请在控制台查看输出！"; >     } > } ### 2、Service层编写标准 **使用Example进行数据库存取操作**   项目使用Example类进行数据库交互，在Service层直接调用Example类即可，具体查询数据的样例代码如下： > // 这是一个Demo样例的服务层实现 > @Service > public class DemoServiceImpl implements DemoService { >     //自动注入userMapper >     @Autowired >     private UserMapper userMapper; >     // 根据Example查询用户 >>     @Override >     public List getUsersByExample() { >         // 首先申明一个users对象用于接收查询结果（用户列表） >         List users = null; >         // 新建用户样例 >         UserExample example = new UserExample(); >         // 获取一个criteria对象，criteria对象用于设置查询条件 >         Criteria criteria = example.createCriteria(); >         // 这句话等同于 WHERE username LIKE '%a%' >         criteria.andUsernameLike("%a%"); >         // 这句话等同于 ORDER BY username ASC >         example.setOrderByClause("username asc"); >         // 执行select查询，参数就是example >         users = userMapper.selectByExample(example); >         // 返回查询结果给controller >         return users; >     } > } **具体用法请参考：https://blog.csdn.net/biandous/article/details/65630783** ### 3、Dao层编写标准 **Mapper文件不需要手动编写**   mapper.xml、mapper、entity都已经通过Maven工具Mybatis Generator自动生成， 如果无特殊需要，无须再手动编写。 ### 4、VO层编写标准 **VO全称Value Object，值对象。主要用于数据交互中，非entity数据的封装。**   例：将用户和订单对象组合，成为用户订单对象。 >// 封装用户订单对象 >public class UserAndOrder { >>     private Order order; >>     private User user; >>     public Order getOrder() { >>         return order; >>     } >>     public void setOrder(Order order) { >>         this.order = order; >>     } >>     public User getUser() { >>         return user; >>     } >>     public void setUser(User user) { >>         this.user = user; >>     } >}
