在实战一种我们完成了hello world，接下来我们就完成连接数据库以及mongodb，首先我们在配置文件application.properties中添加如下配置：
#connect mysql
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=1988131zjp
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.max-idle=10
spring.datasource.max-wait=10000
spring.datasource.min-idle=5
spring.datasource.initial-size=5
spring.datasource.jdbc-interceptors=ConnectionState;SlowQueryReport(threshold=0)
#rabbitmq
spring.rabbitmq.host=192.168.20.102
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin
#mongodb mongodb 3.x 只支持这种方式
#spring.data.mongodb.uri=mongodb://192.168.20.102/local
spring.data.mongodb.host=192.168.20.102
spring.data.mongodb.port=27017
server.port=8080
server.session.timeout=10
server.tomcat.uri-encoding=UTF-8
然后再pom.xml加入下面的配置，配置文件如下:
<?xml version="1.0" encoding="UTF-8"?>

添加完成以后我们在SpringBootTest.java中加入如下的代码最后代码如下:
import com.datababy.enity.Customer;
import com.datababy.enity.Test;
import com.datababy.service.CustomerRepository;
import com.datababy.service.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import org.springframework.web.bind.annotation.*;
import java.util.List;
/**

*/
@RestController
@ComponentScan({"com.datababy.*"})
@EnableMongoRepositories
@EnableAutoConfiguration
public class SpringBootTest {
@Autowired
private TestService services;
@Autowired
private CustomerRepository customerRepository;
@ResponseBody
@RequestMapping(value = "/")
public String location() {
return "北京";
}
@ResponseBody
@RequestMapping(value="/get")
public List<Test> getTest(){
return services.getTest();
}
@RequestMapping(value = "/addCustomer", method = RequestMethod.GET)
public Customer addCustomer(){
return customerRepository.save(new Customer("test1","test1"));
}
public static void main(String[] args) {
SpringApplication.run(SpringBootTest.class, args);
}
}
最后项目结构结果如下图：
