下载springboot的包

链接: https://spring.io/projects/spring-boot

使用idea或者eclipse导入Maven项目

• 在pom.xml中添加依赖

<!--mybatis的依赖包-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.0</version>
</dependency>
<!--oracle的依赖包-->
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0</version>
</dependency>
<!--springboot 热部署-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>

<!--插件-->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>true</fork>
</configuration>
</plugin>
</plugins>
</build>

##dataSource数据源配置
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@127.0.0.1:1521/orcl
spring.datasource.username=yjy
spring.datasource.password=yjy

##Mybatis映射实体类和映射文件配置,扫描哪个包
mybatis.typeAliasesPackage=com.cgzx.certificates.entity
mybatis.mapperLocations=classpath:com/cgzx/certificates/dao/*Mapper.xml

#debug
logging.level.org.springframework=WARN
logging.level.com.github.ArchiveService.dao=DEBUG
loggin.file=logs/srping-boot-loggin.log

#service端口配置和项目路径配置
server.port=8082
#server.servlet.context-path=/certificates

项目目录如下

• 资源放在resources中,比如html,jar包
  

三个层的代码

• controller层

package com.cgzx.certificates.controller;

import com.cgzx.certificates.entity.User;
import com.cgzx.certificates.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping(value = "/select")
public class controller {
@Autowired
private UserService userService;
@RequestMapping(value = "/getUser")
public List<User> getUser(){
System.out.println("jinlaile");
List<User> user = userService.getUser();
System.out.println(user);
return user;
}
@RequestMapping(value = "/ok")
public String ok(){
System.out.println("ok");
return "ok";
}
}

• Service层

package com.cgzx.certificates.service;

import com.cgzx.certificates.dao.UserMapper;
import com.cgzx.certificates.entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserMapper userMapper;
@Override
public List<User> getUser() {
List<User> user = userMapper.getUser();
return user;
}
}

• dao层

package com.cgzx.certificates.dao;

import com.cgzx.certificates.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
@Mapper
public interface UserMapper {
List<User> getUser();
}

</mapper>

运行结果

• 访问资源
  

• 访问select/getUser接口成功拿到数据
