application.properties

spring.mvc.view.suffix=.jsp

#dataSource
spring.datasource.type=org.apache.commons.dbcp.BasicDataSource
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:orcl
spring.datasource.username=scott
spring.datasource.password=tiger

#springMVC applicationContext-dao.xml SqlSessionFactory mapperLocations
mybatis.mapper-locations=classpath:mapper/*.xml

 

dao,service,entity略，同springMVC一样

 

启动

package com.springboot;

import javax.sql.DataSource;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
//相当于mybatis scan
@MapperScan("com.springboot.dao")
public class App extends SpringBootServletInitializer implements CommandLineRunner {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
// TODO Auto-generated method stub
return super.configure(builder);
}

@Autowired
private DataSource dataSource;

public static void main(String[] args) {
SpringApplication.run(App.class, args);
}

@Override
public void run(String... args) throws Exception {
System.out.println("DATASOURCE:" + dataSource);

}
}
