#### 第一步，创建包和类 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDU1MDQ5MA_size_16_color_FFFFFF_t_70]

**第二步，书写User类的Controller控制器**

**调用service接口方法**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDU1MDQ5MA_size_16_color_FFFFFF_t_70 2]

**实现类serviceImpl具有实现**

**书写非逆向工程实现的根据user\_id查询**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDU1MDQ5MA_size_16_color_FFFFFF_t_70 5]

#### 第三步：启动结果 ####

数据库添加数据

启动路径：http://localhost/user/get?id=1

**显示结果**

#### 备注 ####

创建dto model 和 vo 的意义

**逆向工程生成**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDU1MDQ5MA_size_16_color_FFFFFF_t_70 8]

**实际model参数**

**返回视图参数**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDU1MDQ5MA_size_16_color_FFFFFF_t_70 10]

--------------------

#### 复用类使用 ####

**创建Common包**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDU1MDQ5MA_size_16_color_FFFFFF_t_70 11]

**创建复用类代码**

package com.springboot.demo.common.response;
    
    
    public class CommonReturnType { 
    
        private String status;
        private Object data;
    
        // 默认成功
        public static CommonReturnType create(Object data) { 
    
            return CommonReturnType.create(data, "success");
    
        }
    
    
    
    
        public static CommonReturnType create(Object data, String status) { 
    
            CommonReturnType commonReturnType = new CommonReturnType();
            commonReturnType.setStatus(status);
            commonReturnType.setData(data);
    
            return commonReturnType;
    
    
        }
    
    getset

**使用复用类**

**结果**
