调教你的Idea

常用配置

1、基本配置

配置UTF-8

显示行号

更改字体和字体大小

设置大小写代码提示

自动导包

自动编译

main提示main方法

配置bash命令行

关闭idea通知

关闭打开上一次项目

关闭更新

保存当前布局

源码自动导入

3、插件安装

Lombok

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <optional>true</optional>
</dependency>

Easy Code

mp-entity

##引入宏定义
$!define

##使用宏定义设置回调（保存位置与文件后缀）
#save("/entity", ".java")

##使用宏定义设置包后缀
#setPackageSuffix("entity")

##使用全局变量实现默认包导入
$!autoImport
import java.io.Serializable;
import lombok.Data;
import lombok.EqualsAndHashCode;
import com.baomidou.mybatisplus.annotation.TableName;
import com.baomidou.mybatisplus.extension.activerecord.Model;
import com.baomidou.mybatisplus.annotation.TableId;


/**
 * @author $!author
 * @since $!time.currTime()
 */
@Data
@TableName("$!{tool.hump2Underline($tableInfo.name)}")
@EqualsAndHashCode(callSuper = true)
public class $!{tableInfo.name} extends Model<${tableInfo.name}> implements Serializable {
    
    private static final long serialVersionUID = $!tool.serial();
    

    ## 主键
    #foreach($column in $tableInfo.pkColumn)
    #if(${column.comment})/**
        * ${column.comment}
        */#end
        
        @TableId
        private $!{tool.getClsNameByFullName($column.type)} $!{column.name};
    #end

    ##非主键
    #foreach($column in $tableInfo.otherColumn)
    #if(${column.comment})/**
        * ${column.comment}
        */#end
    
        private $!{tool.getClsNameByFullName($column.type)} $!{column.name};
    #end
}

mp-mapper

##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "Mapper"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/mapper"))


#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}mapper;

import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import org.apache.ibatis.annotations.Mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;

/**
 * @author $!author
 * @since $!time.currTime()
 */
@Mapper
public interface $!{tableName} extends BaseMapper<$!{tableInfo.name}> {
   
}

mp-service

##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "Service"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/service"))



#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}service;

import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import com.baomidou.mybatisplus.extension.service.IService;

/**
 * @author $!author
 * @since $!time.currTime()
 */
public interface $!{tableName} extends IService<$!{tableInfo.name}> {

}

mp-service-impl

##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "ServiceImpl"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/service/impl"))


#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}service.impl;

import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import $!{tableInfo.savePackageName}.mapper.$!{tableInfo.name}Mapper;
import $!{tableInfo.savePackageName}.service.$!{tableInfo.name}Service;

import org.springframework.stereotype.Service;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;

/**
 * @author $!author
 * @since $!time.currTime()
 */
@Service
public class $!{tableName} extends ServiceImpl<$!{tableInfo.name}Mapper, $!{tableInfo.name}> implements $!{tableInfo.name}Service {

}

5、集成maven

下载安装maven 并配置环境变量

Path 
;%M2_HOME%\bin;


M2_HOME
D:\Eclipse EE\apache-maven-3.5.4

maven配置文件配置

#配置本地仓库文件夹
<localRepository>F:\Maven_respo</localRepository>


#配置阿里云镜像
<mirrors>
    <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>central</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>
<mirrors>
    
    
#配置java版本
<profile>
<id>jdk-1.8</id>
<activation>
	<activeByDefault>true</activeByDefault>

6、集成tomcat

点击工具栏

点击 + 号选择tomcat Server 再选择Local 如果找不到Tomcat Server 则在33 items more里面

设置Tomcat

将项目添加到Tomcat

常见问题

启动类灰色

Module灰色

开启Run Dashboard

<component name="RunDashboard">
    <option name="configurationTypes">
      <set>
        <option value="SpringBootApplicationConfigurationType" />
      </set>
    </option>
    .......
  </component>

配置Logback

logback-spring.xml

<configuration debug="false" scan="false">
	<property name="log.path" value="logs/${project.artifactId}"/>
	<!-- 彩色日志格式 -->

创建项目

1、创建普通java项目

2、创建javaweb项目

3、创建maven项目

修改目录结构

修改servlet版本为3.1 (web.xml)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    
    
    
</web-app>

修改junit版本为4.11(pom.xml 3.x不支持注解式测试)

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>

补全依赖以ssm框架为例(pom.xml)
