二、编写mybatis-plus的代码生成工具

调整目录结构

技术图片

在util下新建mybatis代码生成工具类

技术图片

mybatisplusutil代码如下

  1 package com.cxw.util;
  2 
  3 import com.baomidou.mybatisplus.annotation.DbType;
  4 import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;
  5 import com.baomidou.mybatisplus.core.toolkit.StringPool;

 10 import com.baomidou.mybatisplus.generator.config.po.TableInfo;
 11 import com.baomidou.mybatisplus.generator.config.rules.IColumnType;
 12 import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
 13 import com.baomidou.mybatisplus.generator.engine.VelocityTemplateEngine;
 14 import org.apache.commons.lang3.StringUtils;
 15 
 16 import java.util.ArrayList;
 17 import java.util.List;
 18 import java.util.Scanner;
 19 
 20 public class MybatisPlusUtil{
 21 
 22     /**
 23      * <p>
 24      * 读取控制台内容
 25      * </p>
 26      */
 27     static String Scanner(String tip) {
 28         Scanner scanner = new Scanner(System.in);
 29         StringBuilder help = new StringBuilder();
 30         help.append("请输入" + tip + "：");
 31         System.out.println(help.toString());
 32         if (scanner.hasNext()) {
 33             String ipt = scanner.next();
 34             if (StringUtils.isNotEmpty(ipt)) {
 35                 return ipt;
 36             }
 37         }
 38         throw new MybatisPlusException("请输入正确的" + tip + "！");
 39     }
 40 
 41     public static void main(String[] args) {
 42         //代码生成器
 43         AutoGenerator autoGenerator = new AutoGenerator();

 50 //        globalConfig.setOpen(false);
 51         //是否覆盖文件

 68             @Override
 69             public IColumnType processTypeConvert(GlobalConfig globalConfig, String fieldType) {
 70                 return super.processTypeConvert(globalConfig, fieldType);
 71             }
 72         });
 73         dataSourceConfig.setUrl("jdbc:mysql://localhost:3306/cxwdb?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false");
 74         dataSourceConfig.setDriverName("com.mysql.cj.jdbc.Driver");
 75         dataSourceConfig.setUsername("root");
 76         dataSourceConfig.setPassword("123456");
 77         autoGenerator.setDataSource(dataSourceConfig);

 85         //模块名
 86         packageConfig.setModuleName(Scanner("模块名"));
 87         packageConfig.setService("service");
 88         packageConfig.setServiceImpl("service.impl");
 89         packageConfig.setEntity("entity");
 90         packageConfig.setController("controller");
 91         packageConfig.setMapper("mapper");
 92         packageConfig.setXml("mapper");
 93         autoGenerator.setPackageInfo(packageConfig);
 94 
 95         // 自定义配置
 96         InjectionConfig injectionConfig = new InjectionConfig() {
 97             @Override
 98             public void initMap() {
 99                 // to do nothing
100             }
101         };
102         List<FileOutConfig> focList = new ArrayList<>();
103         focList.add(new FileOutConfig("/templates/mapper.xml.vm") {
104             @Override
105             public String outputFile(TableInfo tableInfo) {
106                 // 自定义输入文件名称
107                 return projectPath + "/src/main/resources/mapper/" + packageConfig.getModuleName()
108                         + "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
109             }

127         autoGenerator.setTemplateEngine(new VelocityTemplateEngine());
128         autoGenerator.execute();
129     }
130 }

通过工具类生成代码

三、spring+springmvc+mybatis-plus 纯注解搭建

1、构建核心配置文件

 1 package com.cxw.config;
 2 
 3 import org.springframework.context.annotation.ComponentScan;
 4 import org.springframework.context.annotation.Configuration;
 5 import org.springframework.context.annotation.FilterType;
 6 import org.springframework.stereotype.Controller;
 7 
 8 
 9 @Configuration
10 @ComponentScan(basePackages = {"com.cxw"},excludeFilters = {
11         @ComponentScan.Filter(type = FilterType.ANNOTATION,value = Controller.class),
12 })
13 /**
14  * 核心配置文件
15  */
16 public class AppConfig {
17 
18 }

2、构建springmvc配置文件

 1 package com.cxw.config;
 2 
 3 import org.springframework.context.annotation.ComponentScan;
 4 import org.springframework.context.annotation.Configuration;
 5 import org.springframework.context.annotation.FilterType;
 6 import org.springframework.stereotype.Controller;
 7 import org.springframework.web.servlet.config.annotation.EnableWebMvc;
 8 
 9 @Configuration
10 @ComponentScan(basePackages = "com.cxw",
11     includeFilters = {@ComponentScan.Filter(type = FilterType.ANNOTATION,
12     value = Controller.class)})
13 @EnableWebMvc
14 /**
15  * springmvc配置文件
16  */
17 public class WebConfig {
18 
19 }

3、构建数据库配置文件

技术图片

1 spring.datasource.user=root
2 spring.datasource.password=123456
3 spring.datasource.driver=com.mysql.cj.jdbc.Driver
4 spring.datasource.url=jdbc:mysql://localhost:3306/cxwdb?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false

4、构建数据库配置文件关联文件

 1 package com.cxw.config;
 2 
 3 import lombok.Data;
 4 import org.springframework.beans.factory.annotation.Value;
 5 import org.springframework.context.annotation.Configuration;
 6 import org.springframework.context.annotation.PropertySource;
 7 
 8 @PropertySource("classpath:db.properties")
 9 @Data
10 @Configuration
11 public class PropertyConfig {
12 
13     @Value("${spring.datasource.url}")
14     private String url;
15     @Value("${spring.datasource.driver}")
16     private String driver;
17     @Value("${spring.datasource.user}")
18     private String user;
19     @Value("${spring.datasource.password}")
20     private String password;
21 
22 }

5、构建mybatisplus配置文件

 1 package com.cxw.config;
 2 
 3 import com.alibaba.druid.pool.DruidDataSource;
 4 import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
 5 import com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean;
 6 import org.mybatis.spring.annotation.MapperScan;
 7 import org.springframework.context.annotation.Bean;
 8 import org.springframework.context.annotation.Configuration;
 9 
10 import javax.sql.DataSource;
11 
12 @Configuration
13 @MapperScan(value = "com.cxw.studentinfo.mapper")
14 public class MybatisPlusConfig {
15     /**
16      * 配置数据源
17      */
18     @Bean
19     public DataSource dataSource(PropertyConfig propertyConfig){
20         DruidDataSource dataSource = new DruidDataSource();
21         dataSource.setUsername(propertyConfig.getUser());
22         dataSource.setPassword(propertyConfig.getPassword());
23         dataSource.setUrl(propertyConfig.getUrl());
24         dataSource.setDriverClassName(propertyConfig.getDriver());
25         return dataSource;
26     }
27 
28     /*@Bean
29     public DataSource dataSource(PropertyConfig propertyConfig) throws Exception {
30         ComboPooledDataSource dataSource = new ComboPooledDataSource();
31         dataSource.setUser(propertyConfig.getUser());
32         dataSource.setPassword(propertyConfig.getPassword());
33         dataSource.setJdbcUrl(propertyConfig.getUrl());
34         dataSource.setDriverClass(propertyConfig.getDriver());
35         return dataSource;
36     }*/
37 
38     /**
39      * 获得getMybatisSqlSessionFactoryBean
40      * @return
41      */
42     @Bean
43     public MybatisSqlSessionFactoryBean sqlSessionFactory(DataSource dataSource){
44         MybatisSqlSessionFactoryBean mybatisPlus  = new MybatisSqlSessionFactoryBean();
45         mybatisPlus.setDataSource(dataSource);
46         return mybatisPlus;
47     }
48 
49 
50     /**
51      * 设置mapper文件的扫描路径
52      * @return
53      */
54    /* @Bean
55     public MapperScannerConfigurer getMapperScannerConfigurer(){
56         MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
57         mapperScannerConfigurer.setBasePackage("com.cxw.studentinfo,mapper");
58         return mapperScannerConfigurer;
59     }*/
60 
61     /**
62      * 分页插件
63      * @return
64      */
65     @Bean
66     public PaginationInterceptor getPaginationInterceptor(){
67         PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
68         //自定义方言 可以没有
69         paginationInterceptor.setDialectType("mysql");
70         return paginationInterceptor;
71     }
72 
73 }

6、构建核心初始化文件

package com.cxw.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;


/**
 * web.xml替代文件，可以简单理解为相web.xml文件
 */
public class WebInit extends AbstractAnnotationConfigDispatcherServletInitializer {
    //将bean加入容器
    @Override
    protected Class<?>[] getRootConfigClasses() {
        //这里可以配置需要加入容器的Bean,同样可以声明配置类,然后加Bean
        return new Class[]{AppConfig.class,MybatisPlusConfig.class};
    }

    //这个也是相当于将Bean加入容器
    //相当于springmvc容器
    // url映射配置,返回spring的配置文件
    //这里WebConfig主要是配置DispatcherSerlvet,视频解析器,JSON等
    @Override
    protected Class<?>[] getServletConfigClasses() {
        //return null;
        return new Class[]{WebConfig.class};
    }
    //拦截请求匹配,只拦截/
    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

四、逻辑代码编写

1、controller代码

package com.cxw.studentinfo.controller;


import com.cxw.studentinfo.entity.TblStudent;
import com.cxw.studentinfo.service.ITblStudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

/**
 * <p>
 *  前端控制器
 * </p>
 *
 * @author cxw
 * @since 2019-09-25
 */
@RestController
@RequestMapping("/studentinfo/tbl-student")
public class TblStudentController {
    private ITblStudentService iTblStudentService;

    @Autowired
    public TblStudentController(ITblStudentService iTblStudentService){
        this.iTblStudentService = iTblStudentService;
    }

    public TblStudentController(){

    }

    @RequestMapping("/gettblstudentbyid/{id}")
    public TblStudent getTblStudentById(@PathVariable("id") String id){
        TblStudent student = iTblStudentService.getById(id);
        return student;
    }

}

2、serivce代码

 1 package com.cxw.studentinfo.service;
 2 
 3 import com.cxw.studentinfo.entity.TblStudent;
 4 import com.baomidou.mybatisplus.extension.service.IService;
 5 
 6 /**
 7  * <p>
 8  *  服务类
 9  * </p>
10  *
11  * @author cxw
12  * @since 2019-09-25
13  */
14 public interface ITblStudentService extends IService<TblStudent> {
15 
16 }

3、impl代码

package com.cxw.studentinfo.service.impl;

import com.cxw.studentinfo.entity.TblStudent;
import com.cxw.studentinfo.mapper.TblStudentMapper;
import com.cxw.studentinfo.service.ITblStudentService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * <p>
 *  服务实现类
 * </p>
 *
 * @author cxw
 * @since 2019-09-25
 */
@Service
public class TblStudentServiceImpl extends ServiceImpl<TblStudentMapper, TblStudent> implements ITblStudentService {

    private TblStudentMapper tblStudentMapper;

    @Autowired
    public TblStudentServiceImpl(TblStudentMapper tblStudentMapper){
        this.tblStudentMapper = tblStudentMapper;
    }

    public TblStudentServiceImpl( ){

    }

4、mapper代码

 1 package com.cxw.studentinfo.mapper;
 2 
 3 import com.cxw.studentinfo.entity.TblStudent;
 4 import com.baomidou.mybatisplus.core.mapper.BaseMapper;
 5 import org.springframework.stereotype.Service;
 6 
 7 /**
 8  * <p>
 9  *  Mapper 接口
10  * </p>
11  *
12  * @author cxw
13  * @since 2019-09-25
14  */
15 @Service
16 public interface TblStudentMapper extends BaseMapper<TblStudent> {
17 
18 }

5、entity代码

  1 package com.cxw.studentinfo.entity;
  2 
  3 import com.baomidou.mybatisplus.annotation.TableId;
  4 import java.time.LocalDateTime;
  5 import com.baomidou.mybatisplus.annotation.TableField;
  6 import java.io.Serializable;
  7 
  8 /**

 11  * </p>
 12  *
 13  * @author cxw
 14  * @since 2019-09-25
 15  */
 16 public class TblStudent implements Serializable {
 17 
 18     private static final long serialVersionUID = 1L;
 19 
 20     /**
 21      * 主键
 22      */
 23     @TableId("id")
 24     private String id;
 25 
 26     /**

 28      */
 29     @TableField("name")
 30     private String name;
 31 
 32     /**

 34      */
 35     @TableField("age")
 36     private String age;
 37 
 38     /**

 40      */
 41     @TableField("sex")
 42     private String sex;
 43

 55 
 56 
 57     public String getId() {
 58         return id;
 59     }
 60 
 61     public void setId(String id) {
 62         this.id = id;
 63     }
 64 
 65     public String getName() {
 66         return name;
 67     }
 68 
 69     public void setName(String name) {
 70         this.name = name;
 71     }
 72 
 73     public String getAge() {
 74         return age;
 75     }
 76 
 77     public void setAge(String age) {
 78         this.age = age;
 79     }
 80 
 81     public String getSex() {
 82         return sex;
 83     }
 84 
 85     public void setSex(String sex) {
 86         this.sex = sex;
 87     }
 88 
 89     public String getDatainsuserid() {
 90         return datainsuserid;
 91     }
 92 
 93     public void setDatainsuserid(String datainsuserid) {
 94         this.datainsuserid = datainsuserid;
 95     }
 96 
 97     public LocalDateTime getDatainstime() {
 98         return datainstime;
 99     }
100 
101     public void setDatainstime(LocalDateTime datainstime) {
102         this.datainstime = datainstime;
103     }
104 
105     @Override
106     public String toString() {
107         return "TblStudent{" +
108         "id=" + id +

113         ", datainstime=" + datainstime +
114         "}";
115     }
116 }

6、mapper.xml代码
