1. IDEA 新建mven工程
1.1 在pom文件中引入SpringBoot相關(guān)依賴
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.6.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
1.2 新建springboot入口類
@EnableAutoConfiguration
@Controller
public class MainController {
@RequestMapping("/")
@ResponseBody
public String home(){
return "Hello World";
}
public static void main(String[] args) {
SpringApplication.run(MainController.class, args);
}
}
到這里springboot工程就搭建好了蓖租，啟動main函數(shù)嫉嘀，瀏覽器地址欄中輸入http://localhost:8080即可埂息。
1.3 pom文件中引入相關(guān)依賴(MySQL連接驅(qū)動 以及mybatis,thymeleaf模板引擎)

1.5 在resource目錄下新建application.yml文件
添加相關(guān)配置
server:
port: 8080
tomcat:
uri-encoding: utf-8
spring:
datasource:
url: jdbc:mysql://localhost:3306/fish?characterEncoding=utf8
username: root
password: 123456
type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: com.mysql.jdbc
mybatis:
mapper-locations: classpath:mapping/*.xml
type-aliases-package: com.fish.model
#pagehelper分頁插件
pagehelper:
helperDialect: mysql
reasonable: true
supportMethodsArguments: true
params: count=countSql
1.6 使用mybatis generator 自動生成代碼
配置pom中g(shù)enerator 插件所對應的配置文件${basedir}/src/main/resources/generator/generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<!-- 是否去除自動生成的注釋 true：是 ： false:否 -->
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--數(shù)據(jù)庫鏈接URL，用戶名棘利、密碼 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/fish" userId="root" password="123456">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成模型的包名和位置-->
<javaModelGenerator targetPackage="com.fish.model" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成映射文件的包名和位置-->
<sqlMapGenerator targetPackage="mapping" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 生成DAO的包名和位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.fish.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成的表 tableName是數(shù)據(jù)庫中的表名或視圖名 domainObjectName是實體類名-->
<table tableName="t_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>
2 Generator代碼生成及Controller注解
2.1 Generator代碼生成代碼生成
在generatorConfig.xml下配置好數(shù)據(jù)庫表信息運行maven插件mybatis-generator:generate -e，
就會在指定目錄下生成model，mapper類以及xml文件
2.2 啟動類中添加相關(guān)注解
@EnableAutoConfiguration
@MapperScan("com.fish.mapper")
@ComponentScan(basePackages={"com.fish"})
public class SpringbootApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootApplication.class, args);
}
}
@MapperScan 指定mapper接口所在包
@ComponentScan 指定springboot啟動時需要掃描的包(@Controller,@Service等)
2.3 編寫Controller Service等
與普通Spring MVC工程一樣媒抠，編寫好Controller及Service類。
@Controller
@RequestMapping(value = "/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value="/login")
@ResponseBody
public String login(){
return "Hello world";
}
}
2.4 啟動springboot
啟動main函數(shù)咏花，地址欄輸入對應的url趴生，http://localhost:8080/user/login即可訪問web應用了。
到這里昏翰，簡單的springboot工程就搭建好了苍匆。
