SpringBoot学习笔记一之本地环境基础搭建

工程创建

Maven创建工程

搜索maven找到project的创建

创建simple project

填写group和artifact

项目

继续创建Module

选择Module

填写信息

选择war

项目出现

如果出现下面的错误

web.xml is missing and is set to true

是因为缺少文件，按照下面的操作解决就可以

继续创建Module,直接finish就可以了，分别创建四个Module

learn-admin-component

learn-admin-entity

完成后

再创建两个maven project：

learn-common-util

learn-common-reverse

全部创建完的工程

建立工程之间的依赖关系

learn-admin-webui 依赖 learn-admin-component

learn-admin-component 依赖 learn-common-util

learn-admin-component 依赖 learn-admin-entity

操作方式：

learn-admin-webui 依赖 learn-admin-component

搜索component,选择我们需要的component上面的groupid会自动出现

就可以看到了

同样的方式完成下面的依赖

learn-admin-component 依赖 learn-common-util

learn-admin-component 依赖 learn-admin-entity

创建数据库和数据库表

CREATE DATABASE `project_learn` CHARACTER SET utf8;

USE project_learn;

DROP TABLE IF EXISTS t_admin;

CREATE TABLE t_admin

(

id INT NOT NULL AUTO_INCREMENT, # 主键

login_acct VARCHAR(255) NOT NULL, # 登录账号

user_pswd CHAR(32) NOT NULL, # 登录密码

user_name VARCHAR(255) NOT NULL, # 昵称

email VARCHAR(255) NOT NULL, # 邮件地址

create_time CHAR(19), # 创建时间

PRIMARY KEY (id)

);

基于Maven的MyBatis逆向工程

在learn-common-reverse的pom文件中添加下面的内容

<code><dependencies>
         <dependency>
         <groupid>org.mybatis/<groupid>
         <artifactid>mybatis/<artifactid>
         <version>3.2.8/<version>
         /<dependency>
/<dependencies>/<code>

再将下面的内容依次添加

开始构建标签

构建过程中用到的插件

具体插件

填写插件

填写插件依赖

下面是配置内容

<code>
<build>

<plugins>
 

<plugin>
<groupid>org.mybatis.generator/<groupid>
<artifactid>mybatis-generator-maven-plugin/<artifactid>
<version>1.3.0/<version>

<dependencies>

<dependency>
<groupid>org.mybatis.generator/<groupid>
<artifactid>mybatis-generator-core/<artifactid>
<version>1.3.2/<version>
/<dependency>

<dependency>
<groupid>com.mchange/<groupid>
<artifactid>c3p0/<artifactid>
<version>0.9.2/<version>
/<dependency>

<dependency>
<groupid>mysql/<groupid>
<artifactid>mysql-connector-java/<artifactid>
<version>5.1.8/<version>
/<dependency>
/<dependencies>
/<plugin>
/<plugins>
/<build>/<code>

创建配置文件generatorConfig.xml

将下面的信息填入

<code>br>         PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
         "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorconfiguration>
         
         <context>
                  <commentgenerator>
                          
                          <property>
                  /<commentgenerator>
                  
                  <jdbcconnection>                                                     connectionURL="jdbc:mysql://localhost:3306/project_learn"
                                                     userId="root"
                                                     password="">
                  /<jdbcconnection>
                  
                  <javatyperesolver>
                          <property>
                  /<javatyperesolver>
                  
                  <javamodelgenerator>
                          
                          <property>
                          
                          <property>
                  /<javamodelgenerator>
                  
                  <sqlmapgenerator>
                           

                          <property>
                  /<sqlmapgenerator>
                  
                  <javaclientgenerator>
                          
                          <property>
                  /<javaclientgenerator>
                  
                  <table>
         /<context>
/<generatorconfiguration>/<code>

完成配置

注意更改数据库

执行逆向生成操作的 Maven 命令

mybatis-generator:generate

进入操作界面

添加命令，执行run

观察信息出现success

这个时候刷新项目就可以看到自动生成的一些文件

里面的一些内容我们补充完成

首先是实体类的构造器，无参、有参和toString，都自动生成就可以

然后将生成的数据放到对应的位置

将learn-common-reverse中的entity目录移动到learn-admin-entity

移动完后

将learn-common-reverse中的AdminMapper.xml文件移动到learn-admin-webui

在learn-admin-webui的resources目录下创建下面的结构，然后将AdminMapper.xml移动过来

移动完后

将learn-common-reverse中的AdminMapper.javal文件移动到learn-admin-component

AdminMapper.java中有个错误，是param缺少jar包，将之前mybatis的配置放到pom中

加入配置

父工程依赖管理

<code><properties>
         
         <spring.version>4.3.20.RELEASE/<spring.version>
         
         <spring.security.version>4.2.10.RELEASE/<spring.security.version>
/<properties>/<code>

配置到parent中pom.xml中

依赖管理，配置信息因为太长我们放到文档最后（ctrl+shift+f可以格式化）

Parent中pom的依赖管理配置信息

<code><dependencymanagement>
