打开idea->new->project
1.选择Spring initializr,其他默认，点击下一步
2.项目配置
Group：对应pom文件中的groupId，项目组织的唯一标识，对应Java包的结构
Artifact：对应pom文件的artifactId，项目唯一标识，对应项目名称
Type：Maven构建的，选择第一个Maven Project
Packaging：打包类型，打包成Jar文件
Java Version：jdk版本，选择1.8
Language：开发语言，选择Java
Version：项目版本，对应pom文件的version
name:项目名称
Description：项目描述，对应pom文件的description
Package：包名
3.选择spring boot版本
4.填写项目名称，项目存放目录，点击Finish完成
5.删除下面三个无关的文件
6.最后的项目结构
查看自动生成的pom.xml文件
4.0.0
com.example
demo
0.0.1-SNAPSHOT
jar
demo
Demo project for Spring Boot
org.springframework.boot
spring-boot-starter-parent
1.5.6.RELEASE
UTF-8
UTF-8
1.8
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
test
org.springframework.boot
spring-boot-maven-plugin
7.新建一个controller测试
@RestController
public class HelloController {
@RequestMapping(value = "/hello")
public String hello(){
return "hello spring boot";
}
}
@RestController的意思就是controller里面的方法都一json格式输出
8.启动DemoApplication
9.到浏览器中输入http://localhost:8080/hello
至此一个spring boot项目创建完毕
10.接下来在pom.xml文件中加入mysql，mybatis和mybaits generator依赖
4.0.0
com.dwzzb
dwzzb
0.0.1-SNAPSHOT
jar
dwzzb
dwzzb web project
org.springframework.boot
spring-boot-starter-parent
1.5.6.RELEASE
UTF-8
UTF-8
1.8
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
test
org.mybatis.spring.boot
mybatis-spring-boot-starter
1.1.1
mysql
mysql-connector-java
5.1.21
org.springframework.boot
spring-boot-maven-plugin
org.mybatis.generator
mybatis-generator-maven-plugin
1.3.2
true
true
mysql
mysql-connector-java
5.1.21
11.在配置文件application.properties中加入数据库的配置信息
spring.datasource.url=jdbc:mysql://localhost:3306/dbname
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
12.创建generatorConfig.xml文件
注意注释的部分
这边已经把对jar包的依赖的classPathEntry配置移到pom中，上面有完整的pom配置。
13.添加一个“RUN运行”，使用maven运行mybatis-generator-maven-plugin插件
点击菜单run中的Edit Configurations，然后点“+”，添加maven，设置如下
14.在run菜单中选择generator
点击绿色小箭头运行
