编写1个程序，使用文件流的相关方法顺序完成以下操作： //读取文件Data.txt中的所有数据； //将读取得到的数据以二进制的形式存放到程序所在目录下的文件Res.dat中； //再次读取Res.dat中的所有数据； //并将这些数据以文本文件的形式存放到程序所在目录下的Res.txt文件中，存放时每行2个数据， //每个数据占10列，右对齐，左边补'C'字符。

1. 在pom.xml文件中添加mybatis-plus和mysql驱动的依赖 ```xml <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.4.3.2</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.22</version> </dependency> ``` 2. 配置数据源和mybatis-plus 在application.properties文件中添加以下配置： ```properties spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8&useSSL=false spring.datasource.username=root spring.datasource.password=123456 # mybatis-plus配置 # 扫描mapper.xml文件的包路径 mybatis-plus.mapper-locations=classpath*:mapper/*.xml # 实体类包路径 mybatis-plus.typeAliasesPackage=com.example.demo.entity # 开启驼峰命名规则 mybatis-plus.configuration.map-underscore-to-camel-case=true ``` 3. 创建Employee实体类 ```java @Data public class Employee { private Long id; private String name; private String password; private Integer age; private String gender; private Date entryDate; private String department; } ``` 4. 创建EmployeeMapper接口 ```java @Mapper public interface EmployeeMapper extends BaseMapper<Employee> { } ``` 5. 创建EmployeeService接口和实现类 ```java public interface EmployeeService extends IService<Employee> { } @Service public class EmployeeServiceImpl extends ServiceImpl<EmployeeMapper, Employee> implements EmployeeService { } ``` 6. 创建EmployeeController ```java @RestController @RequestMapping("/employee") public class EmployeeController { @Autowired private EmployeeService employeeService; @PostMapping("/register") public Result register(@RequestBody Employee employee) { boolean success = employeeService.save(employee); return success ? Result.success() : Result.failure("注册失败"); } } ``` 7. 创建前端页面（使用layui和ajax） ```html <!DOCTYPE html> <html> <head> <title>员工注册</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://cdn.staticfile.org/layui/2.5.7/css/layui.min.css"> </head> <body> <div class="layui-container" style="margin-top: 50px;"> <div class="layui-row"> <div class="layui-col-md-offset3 layui-col-md6"> <form class="layui-form" id="register-form"> <div class="layui-form-item"> <label class="layui-form-label">姓名</label> <div class="layui-input-block"> <input type="text" name="name" lay-verify="required" placeholder="请输入姓名" autocomplete="off" class="layui-input"> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">密码</label> <div class="layui-input-block"> <input type="password" name="password" lay-verify="required" placeholder="请输入密码" autocomplete="off" class="layui-input"> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">年龄</label> <div class="layui-input-block"> <input type="text" name="age" lay-verify="required|number" placeholder="请输入年龄" autocomplete="off" class="layui-input"> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">性别</label> <div class="layui-input-block"> <input type="radio" name="gender" value="男" title="男" checked> <input type="radio" name="gender" value="女" title="女"> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">入职时间</label> <div class="layui-input-block"> <input type="text" name="entryDate" lay-verify="required" placeholder="yyyy-MM-dd" autocomplete="off" class="layui-input"> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">部门</label> <div class="layui-input-block"> <input type="text" name="department" lay-verify="required" placeholder="请输入部门" autocomplete="off" class="layui-input"> </div> </div> <div class="layui-form-item"> <div class="layui-input-block"> <button class="layui-btn" lay-submit lay-filter="register">注册</button> <button type="reset" class="layui-btn layui-btn-primary">重置</button> </div> </div> </form> </div> </div> </div> <script src="https://cdn.staticfile.org/jquery/3.5.1/jquery.min.js"></script> <script src="https://cdn.staticfile.org/layui/2.5.7/layui.min.js"></script> <script> layui.use(['form', 'layer'], function () { var form = layui.form; var layer = layui.layer; form.on('submit(register)', function (data) { $.ajax({ type: "POST", url: "/employee/register", contentType: "application/json", data: JSON.stringify(data.field), success: function (res) { if (res.code === 0) { layer.msg("注册成功"); } else { layer.msg(res.msg); } }, error: function () { layer.msg("网络错误"); } }); return false; }); }); </script> </body> </html> ``` 以上就是使用mybatis-plus、springboot、layui和ajax实现员工注册的完整代码。
