使用springboot暴露oracle数据接口的问题

江南才子

　　新建一个Spring Initializr项目

　　2.把pom.xml文件中的oracle依赖换成自己的oracle版本依赖：
　　原来的：

　　现在的：

<dependency>
      <groupId>com.oracle</groupId>
      <artifactId>ojdbc6</artifactId>
      <version>11.2.0.1.0</version>
    </dependency>

　　3.编辑application.yml

spring:
  datasource:
  driver-class-name: oracle.jdbc.driver.OracleDriver
  url: jdbc:oracle:thin:@192.168.21.200:1521:orcl
  username: alisa
  password: alisa

　　4.创建实例类——Userinfos.java：

package cn.alisa.myspboracle.entity;
 
import java.util.Date;
 
public class Userinfos {
  private int userid;
  private String username;
  private Date birthyear;
  private float userhight;
 
  public int getUserid() {
    return userid;
  }
 
  public void setUserid(int userid) {
    this.userid = userid;
  }
 
  public String getUsername() {
    return username;
  }
 
  public void setUsername(String username) {
    this.username = username;
  }
 
  public Date getBirthyear() {
    return birthyear;
  }
 
  public void setBirthyear(Date birthyear) {
    this.birthyear = birthyear;
  }
 
  public float getUserhight() {
    return userhight;
  }
 
  public void setUserhight(float userhight) {
    this.userhight = userhight;
  }
}

　　创建接口类——UserinfosDAO.java

package cn.alisa.myspboracle.dao;
 
import cn.alisa.myspboracle.entity.Userinfos;
import org.apache.ibatis.annotations.Select;
 
import java.util.List;
 
public interface UserinfosDAO {
  @Select("select userid,username,birthyear,userhight from userinfos")
  public List<Userinfos>findAll();
 
  @Select("select userid,username,birthyear,userhight from userinfos where username like '%${name}%'")
  public List<Userinfos>findUserSameName(String name);
}

　　创建服务类——UserinfosService.java

package cn.alisa.myspboracle.service;
 
import cn.alisa.myspboracle.dao.UserinfosDAO;
import cn.alisa.myspboracle.entity.Userinfos;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import java.util.List;
 
@Service
public class UserinfosService {
  @Autowired
  private UserinfosDAO udao;
 
  public List<Userinfos>searchAll(){
    return udao.findAll();
  }
 
  public List<Userinfos>sameName(String name){
    return udao.findUserSameName(name);
  }
}

　　创建控制层类——InitCtrl.java:

package cn.alisa.myspboracle.ctrl;
 
import cn.alisa.myspboracle.entity.Userinfos;
import cn.alisa.myspboracle.service.UserinfosService;
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
public class InitCtrl {
  @Autowired
  private UserinfosService userinfosService;
 
  @RequestMapping("/all")
  public List<Userinfos>init(){
    return userinfosService.searchAll();
  }
 
  @RequestMapping("/same")
  public List<Userinfos>same(String name){
    return userinfosService.sameName(name);
  }
}

　　编辑MyspboracleApplication.java类：

package cn.alisa.myspboracle;
 
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
@MapperScan("cn.alisa.myspboracle.dao")
public class MyspboracleApplication {
 
  public static void main(String[] args) {
 
    SpringApplication.run(MyspboracleApplication.class, args);
  }
 
}

　　运行此类（MyspboracleApplication.java），在浏览器中输入"http://localhost:8080/all"或者"http://localhost:8080/same?name=l"即可看到想要的结果。
