spring boot mybatis mysql

摘要: spring boot mybatis mysql

第一步配置spring boot的application.properties
Java代码


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。
Xml代码

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。
Java代码


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。
