2022-07-24 17:57:00 【51CTO】

To readers

Now the environment, are you all ready ？

Then the next step is real development ,Idea I didn't give you the download link on the official website , Now here you are ： https://youtrack.jetbrains.com/articles/IDEA-A-21/Release-Notes

I downloaded it 2021.3.2 Of , Corresponding “ Continuous learning ” Development jar package

Sky wing cloud disk Cherish the good life Family cloud | Network disk | File backup | Resource sharing ( Access code :6in8)

The recommended Idea To configure ： Probably the best use IDEA Set up _ Zhangzhishuai ‍ The blog of -CSDN Blog

“ Continuous learning ” The configuration file ：

Two ways ：

The first one is ：

Put the downloaded package in the right place , Yes ja-netfilter.jar Hold down Shift Right click the mouse to copy the path , If it can be opened Idea Development tools , Go to help–>Edit Custom VM Options Copy the content in .

The second kind ：

open Idea The installation directory bin Under the idea64.exe.vmoptions file , Copy “ Continuous learning ” Configuration information goes in , Just reopen .

The chicken soup cooking time is over , It's time for development

1. Create project

open Idea Manually create a maven Empty item , Include several module folders

step ：

File --> New --> Project --> Maven --> Select corresponding Project SDK（ namely JDK） --> Next --> Name --> Localtion --> GroupId（com.fyupeng）–> ArtifactId（fyupeng-blog） --> Version（1.0-SNATSHOT）

Directory structure ：

– fyupeng-blog

– fyupeng-blog-commons

– fyupeng-blog-pojo

– fyupeng-blog-mapper

– fyupeng-blog-service

– fyupeng-blog-api

establish 1 individual Project 5 individual Model,model Is in File --> New --> Model Next

After the operation is completed and no error is detected , Open the root directory pom.xml

2. Configuration dependency and configuration information

commons It mainly includes public api package

You can directly download what I often use , link ： GitHub - fyupeng/SoftWare: Software download address

Develop the first interface ：

stay api Resource directory in the module （resources） Add files to application.properties file

Add two lines of configuration information ：

application.properties

############################################################
#
# Server
#
############################################################
server.port=8080

############################################################
# Server - tomcat
############################################################

General configuration files use unicode code , Decode when necessary , Otherwise, it is easy to get garbled

Provide Unicode Online codec tools ： On-line Unicode Encoding conversion -Unicode and ASCII Online transfer - Chinese to Unicode Tools

3. Write the first interface

api New China controller Catalog

BasicController It is mainly used to configure basic static variables , Supply inherits its subclasses Controller Use

package com.fyupeng.controller;

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


@RestController
public class BasicController {


}

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

    public BlogJSONResult helloWorld() {

4. Reverse engineering

What to do next ： Reverse engineering （ As the name suggests, I am too lazy to write by myself pojo Layer and the mapper layer ）

Reverse engineering links ： GitHub - fyupeng/mybatis-generator: mybatis Reverse engineering

Create database users

Grant user rights

Tips ：

with grant option: Multiple authorization can superimpose permissions

Here you can use ' user name '@' host '

When authorizing , Not available ' database .' surface ', You can use the database name @‘ surface ’

Reverse engineering creates User surface , I'm using Navicat

Reverse engineering I provide two ：

An interface ：

Interface oriented uses maven project

Just configure jdbc Relevant connections and database tables

Maximize and reduce development costs , I use interface oriented development

First put the generated files into the corresponding model in ,util Under the MyMapper Put it in commons Under bag utils Next

Configuration database jdbc Connection pool , Need to application.properties Add configuration information to ：

spring.datasource.url=jdbc:mysql://localhost:3306/fyupeng_blog?useUnicode=true&characterEncoding=utf8&useJDBCComplliantTimezoneShift=true\
  &useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=fyupeng
spring.datasource.password=*****
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.druid.initial-size=1
spring.datasource.druid.min-idle=1
spring.datasource.druid.max-active=20
spring.datasource.druid.test-on-borrow=true
spring.datasource.druid.stat-view-servlet.allow=true

And then there are mapper.xml file , Put it in mapper Modular resources in mapper Under the folder

This folder needs to be told springboot Scan and put the instance object into spring In the container , So it can be application.xml Add configuration information ：

############################################################
#
# mybatis  To configure

Preliminary Configuration completed

6. Develop the second interface

For testing MySQL database

@ApiOperation(value = "testMysql", notes = " Test the interface of the database ")
@RequestMapping(value = "/testMysql")
    public BlogJSONResult testMysql() {
        User user = new User();
        user.setId(Sid.next());
        user.setName(" Xiao Ming ");
        user.setAge(21);
        user.setSex(" male ");
        userMapper.insert(user);
        return BlogJSONResult.ok();
    }

Data table garbled , Lead to ERROR 1366 (HY000): Incorrect string value: '\xE5\xB0\x8F\xE6\x98\x8E' for column 'name' at row 1

You can use the following method to set , All fields will take effect

If the database is created, attach default charset=utf8 Can solve the problem of disorderly code

Handwritten blog platform ~ the second day _xml_02

Edit switch to center

Data sheet

More wonderful on the third day , Hiccup kid paper is continuing to follow up …

Any bug Feel free to contact the author , I will solve your doubts as soon as possible , Let's finish this job together , Just do other more interesting things together, haha .

By the way, I would like to share with you the completed blogs , This development is the second development , The main thing is to share what you have learned , Of course, I will definitely gain something ！

I'll give you the link tomorrow , I hope to see you tomorrow ！

By the way, I would like to share with you my technical column in recent years ： https://github.com/fyupeng
