参考来源:https://github.com/hoserdude/spring-boot-mybatis-profile-sandbox
按照上面的例子先导入到自己的IDE中。
第一步配置spring boot的application.properties
spring.datasource.url=jdbc:mysql://localhost:3306/mecom
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.main.show-banner=false
第二步配置pom.xml 这个配置也很重要 我的与参考原来有些不一致。

第三步的就是java代码 tomcat我用的tomcat7 tomcat启动会加载这个Application.java 这个很关键。
package com.zmall;
import org.apache.ibatis.session.SqlSessionFactory;
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.builder.SpringApplicationBuilder;
import org.springframework.boot.context.embedded.MultipartConfigFactory;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseBuilder;
import javax.servlet.MultipartConfigElement;
import javax.sql.DataSource;
@Configuration
@EnableAutoConfiguration
@MapperScan(basePackages = "com.zmall.mapper")
@ComponentScan(basePackages = "com.zmall")
public class Application extends SpringBootServletInitializer {
@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setMaxFileSize("5MB");
factory.setMaxRequestSize("5MB");
return factory.createMultipartConfig();
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
// @Bean
// public DataSource dataSource() {
// return new EmbeddedDatabaseBuilder().setType(H2).build();
// }
@Bean
public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
sessionFactory.setDataSource(dataSource);
return sessionFactory.getObject();
}
}
希望大家能够成功。
