spring boot mybatis mysql

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。

                </dependencies>
            </plugin>
        </plugins>
    </build>
</project>

?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。
