一、创建项目
1.右键-->New-->Project...
2.选中Maven Project，点击next
3.选中第一个
4.添写Group Id，Artifact Id，选择Compiler Level为1.6
5.创建完成后的目录结构如下
二、创建目录环境
1.修改pom.xml，更新内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.lm.spring-boot</groupId>
<artifactId>spring-boot</artifactId>
<version>0.0.1-SNAPSHOT</version>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.0.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--视图采用freemarker渲染 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<!-- JDBC -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<!-- mybatis -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.2</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.2.8</version>
</dependency>
<!-- mysql -->

<version>1.2.13</version>
</dependency>
</dependencies>
<build>
<plugins>

<configuration>

</configuration>

</dependency>
</dependencies>
</plugin>
</plugins>
<!-- 指定最终生成jar包的文件名-->
<finalName>spring-boot</finalName>
</build>
</project>
2.更新maven相关的jar包
3.创建相关的包和目录，创建后的目录结构如下：
application包存放的是应用程序启动类。
common包存放应用类。
controller包存放控制类。
dao包存放数据类。
model包存放实体类。
service包存放服务类。
mapper文件夹存放映射文件。
static文件夹存放页面相关的静态文件，如js、css等。
web文件夹存放ftl页面。
三、创建程序入口Application.java
在application包创建类文件Application.java
类文件内容为：
package sinosoft.bjredcross.application;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.tomcat.jdbc.pool.DataSource;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan(basePackages={"sinosoft.bjredcross"})//指定spring管理的bean所在的包
@MapperScan("sinosoft.bjredcross.dao")//指定mybatis的mapper接口所在的包
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
//创建数据源
@Bean
@ConfigurationProperties(prefix = "spring.datasource")//指定数据源的前缀 ,在application.properties文件中指定
public DataSource dataSource() {
return new DataSource();
}
//创建SqlSessionFactory
@Bean
public SqlSessionFactory sqlSessionFactory() throws Exception {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mapper/*.xml"));
return sqlSessionFactoryBean.getObject();
}
//创建事物管理器
@Bean
public PlatformTransactionManager transactionManager() {
return new DataSourceTransactionManager(dataSource());
}
}
四、创建配置文件application.properties
在src/main/resource目录创建文件application.properties，文件内容如下：
#datasource spring.datasource.url=jdbc\:mysql\://localhost\:3306/firstaid?useUnicode\=true&characterEncoding\=utf8&zeroDateTimeBehavior\=convertToNull spring.datasource.username=root spring.datasource.password=SinoSoftadmin123 spring.datasource.driver-class-name=com.mysql.jdbc.Driver # FREEMARKER (FreeMarkerAutoConfiguration) spring.freemarker.allow-request-override=false spring.freemarker.allow-session-override=false spring.freemarker.cache=false spring.freemarker.charset=UTF-8 spring.freemarker.check-template-location=true spring.freemarker.content-type=text/html spring.freemarker.enabled=true spring.freemarker.expose-request-attributes=true spring.freemarker.expose-session-attributes=true spring.freemarker.expose-spring-macro-helpers=true spring.freemarker.prefer-file-system-access=true spring.freemarker.request-context-attribute=request spring.freemarker.suffix=.ftl spring.freemarker.template-loader-path=classpath:/web/ spring.freemarker.settings.template_update_delay=0 spring.freemarker.settings.default_encoding=UTF-8 spring.freemarker.settings.classic_compatible=true spring.freemarker.order=1 #server server.port=8088
五、系统运行测试
在Application.java文件上右键run as点击java application
执行正常显示如下：
